11 Yue 11 Ri to 15, Dagang Oilfield Company organization of production and management departments, key subordinates in 22 production units with energy-efficient enterprises can be created to conduct on-site assessment, summed up a lot of value with the promotion of energy-saving experience and practices. Among them, especially the practice of science and technology energy-saving. The company said energy-saving management personnel since last year, Dagang Oilfield promote the use of the 15 new energy-saving technologies, mechanical oil recovery, oil field water injection, oil and gas gathering and transportation, heating heating, electricity distribution system, carried out the five-round, three-dimensional energy-saving technological transformation, has made significant energy-saving effect. These three energy-saving technology is important promotional value, therefore be introduced.

waste heat recovery natural gas generator sets

oil Wuchang West 2 West, Hong Kong joint stations bear the crude oil gathering and transportation, waste water re-injection and other tasks, produces more than 20,000 cubic meters per day of associated gas, while consuming a lot of power. In order for the associated natural gas into electricity to meet the West, two co-station electricity needs, Dagang Oilfield organization installed five 500-kilowatt gas-fired generating units. However, the personnel in the test found that only 35% of associated gas generator into electricity, 30% with the gas emissions, 25% of the engine cooling water taken away, there are about 10% distributed through the fuselage and so on.

looked at the energy generated per day of associated natural gas, so lost in vain away, is responsible for energy-saving technical staff, such as thorn in the side, restless, so put forward such an idea: up of these waste heat recovery for heating the station’s outer transmission of crude oil, natural gas furnace to replace the burning. Although they are not familiar with waste heat recovery technology, but they firmly believe that as long as in learning, we will be able to master. As a result, they took part in the Dagang oil field will be organized by the exchange of energy-saving technologies, learn to use knowledge and technology, waste heat recovery, but also to the relevant business study tour last, a joint station of the West 2 to design a waste heat recovery flow chart, that is, in every Taiwan generator exhaust pipe heat recovery unit installed, the laying of 100-meter heat medium pipes and the installation of another of the two circulating water pumps and two plate heat exchanger.

of the project put into operation, the 5 units of natural gas generating units crossing the smoke from the exhaust gas temperature of 356 degrees Celsius before installation down to 108 degrees Celsius, the waste heat recovery for heating oil, the heat output of 1274 kilowatts per hour, per day to save 3108 cubic meters of natural gas. To see such an effect, the company promoting the project in a timely manner, has now eight points were 32 natural gas generating waste heat recovery technological innovation, external heat input for oil heating and heating in winter.

transformation of old-fashioned blue 12-type pumping unit

Dagang Oilfield, a large number of the last century put into operation 80 years old blue 12-type pumping unit, even though in normal operation, but has been unable to meet the needs of today extraction process. Because the old oil into the later stages of development, the depth of oil well pump hanging a general increase in the general pumping load increases, process to request a long-stroke pumping unit, low-red times. If, however, abandon the obsolete, re-purchase of a new pumping units, we need to invest huge sums of money, if it continues to use, not only affects the oil production, but energy consumption is also high.

energy-saving potential exists in the high-energy-consuming equipment into. Dagang Oilfield supplies and equipment energy conservation authorities and established by the Ministry subject to the blue 12-type pumping unit conducted a special study, and choose a well for oil extraction plant in four trials. In the design and testing process, the researchers in-depth analysis and study, explore new ideas, time and again modify the technical route, and finally blue 12-type rear walking beam pumping unit installed in a certain angle with the tour Leung Shing-bias with weights , by the bar right under the partial suspension point load a balance and realize both the increase of pumping crude oil and energy-efficient purpose, succeeded in obtaining a scientific research.

After transformation, a blue 12-type pumping unit, and the supporting electrical power from 55 kilowatts to 37 kilowatts, energy-saving rate of 32.73%, the annual energy-saving 1.2 × 104 kilowatt hours and a maximum stroke increased by 3.3 m to 5 meters. Oil four plants commonly used by the 44 mm diameter pump pump, pumping unit impulse times 4 times / min, crude oil moisture content of 90%, the annual average number of days open wells 300 days calculation, one-year increase of crude oil pumping 12.2 tons . At the same time, the purchase of a 5-m-cycle of the beam pumping unit, about 30 million yuan, while the extended range energy-saving on average a total investment of 100,000 yuan each. Lan-type pumping unit 12 after the effectiveness of such a remarkable transformation, Dagang Oil Field will promote the use of the various oil extraction plant has been transformed more than 120 units.

Applications 3 partial pressure of water injection technology

energy-saving technology is everywhere. Oil three plants from a water injection station in conjunction with two water pumping stations, is responsible for five oil station 14 water injection wells task of 1164 cubic meters of water daily injection. Because of the different geological structure, the suction pressure of injection wells vary widely, but prolonged pressure injection pumps are to meet the high-pressure water injection wells as a standard, therefore, a low pressure suction wells have had a lot of damage, resulting in energy consumption of water injection system high.

how to reduce water consumption? Dagang Oilfield organized technical personnel from a water injection station in conjunction process conditions was analyzed and found that injection with high pressure water injection system when the motor input power was significantly higher than with high and low pressure water injection system when the two motor input power, therefore, put forward the implementation of high, medium and low partial pressure of three rehabilitation programs. In the transformation process, the maintenance of five water injection pressure plunger pump for the suction pressure is higher than 15 MPa six water injection wells; to three plunger pump 2 #, 3 #, 4 # pump as a medium-pressure injection pump, in order to suction pressure of less than 15 MPa of the seven water injection wells; to a # 3 piston pump as a low-pressure injection pump pumps, for suction pressure of less than 2.5 MPa in a water injection wells, while water flow inside the station, station outside the pipe network has been transformed.

transformation from a joint water stop after the one pressure level into three pressure levels, energy-saving effect immediately apparent: the average unit consumption by the injection pump unit 7.55 kwh / m down to 4.03 kwh / cubic meters, Japan Day 4097 kwh electricity, per 1 kWh / m 0.64 yuan per day for 2,622 yuan may be to save money; transformation invested 250,000 yuan, investment recovery period is only 4 months. Similarly, the Dagang Oilfield Oil Production Plant immediately in all promotion, is now eight injection points to energy-saving technological transformation of the partial pressure of water.

大港油田推广利用新能源，节能技术纪事

11乐11日至15日，大港油田公司的生产和管理部门，在22个单位与能源生产效率的主要下属企业组织可以创建进行现场评估，总结与推广节能很大的价值节能经验和做法。其中，特别是实践的科学和技术节能。该公司表示，节能自去年以来，管理人员，促进大港油田的15个新使用节能技术，机械采油，油田注水，油气集输，供暖供热，供电系统，进行出了五轮，三维节能技术改造，取得了显着的节能效果。这三个节能技术是重要的推广价值，因此，采用的。

余热回收的天然气发电机组

石油武昌西2西，香港联合站承担收集和原油，废水再运输，注射和其他任务，生产2万多立方米，每天伴生气，而消耗了很多力量。为了伴生天然气，以便为电能，以满足，两个共同西站的电力需求，大港油田组织安装了5 500千瓦的燃气发电机组。不过，在测试人员发现，只有35％转化为电能，30％的气体发生器的气体的排放，25冷却水带走的引擎％，有10％左右通过机身等分发。

看着占伴生天然气每天产生的能源，所以白白丢失了，负责节能，如在侧，不安眼中钉技术人员，因此提出这样一个想法：这些组成废物加热站原油外传输热回收，天然气炉，以取代燃烧。虽然他们不与废热回收技术熟悉，但他们坚信，只要在学习，我们将能够掌握。因此，他们参加了大港油田的部分将由能源节能技术交流组织，学会运用知识和技术，余热回收，而且对相关业务考察，{zh1}一联合站西2设计了废热回收流程，即在每一个台湾发电机排气管热回收安装单位，铺设了100米长的热媒管道和两个循环水泵和二板式换热器另一个安装。

的投产项目

，天然气发电通道安装前下降到108摄氏度，取暖油余热回收，从356度的废气温度摄氏烟雾单位的5个单位，热输出每小时的1274万千瓦，每天节省3108立方米的天然气。看到这样的效果，促进公司及时项目，现在已经8点32天然气发电余热回收技术创新，取暖油和冬季取暖外部热输入。

改造老式蓝12型抽油机

大港油田，投产一个80岁的蓝12型抽油机，在正常运行，即使把上个世纪很多，但有已不能满足今天的提取工艺的需要。由于发展到后期，石油油井深度旧泵挂在一般抽水负荷增加的普遍增加，处理请求长冲程抽油机，低红色倍。但是，如果放弃过时的，重新建立一个新的抽水单位购买，我们需要投入巨额资金，如果继续使用，不仅影响石油生产，但能源消耗也很高。

节能潜力存在于高耗能的设备，。大港油田用品和设备节能当局和该部受蓝12型抽油机建立进行了专门研究，并选择良好的四项审判采油厂。在设计和测试过程中，研究人员在深入分析和研究，探索新的思路，多次修改的技术路线，{zh1}蓝12型游梁抽油机后在与各大旅行社梁成一定的角度安装单位偏见与重量，由主管部分中止点负载平衡，实现既抽水原油和能源效率的目的，增加栏右侧获得一个科学研究成功。

改造后，蓝色12型抽油机，从五十五千瓦配套电力37万千瓦，节能的32.73％，每年节能1.2 × 104千瓦小时，{zd0}行程提高利率3.3米至5米。石油四家工厂通常使用的44毫米直径油泵，抽油机冲次，4次/分，原油的90％，每年的平均天数300天开放井计算，一年抽油的原油含水量增加12.2吨。同时，一个5购买米周期的游梁式抽油机，约3000万人民币，扩大范围的能源，平均10万人民币的总投资储蓄。兰式抽水后，这种转变的成效显着的单位12个，大港油田将促进各采油厂的使用已改造120多个单位。

应用3注水技术氧分压

节能技术是无处不在。石油三从一个两个抽水站，注水站结合植物，负责5个油站的14注水井的1164立方米水表每日注射任务。由于不同的地质结构，注水井吸入压力差别很大，但长期高压注射泵，以满足高压水作为一个标准的注水井，因此，低气压吸井产生了很大损失，导致高能量注水系统能耗。

如何减少用水量？大港油田组织了一个共同的工艺条件下注水站的技术人员进行了分析，结果发现注射用高压水喷射系统，当电机输入功率显着高于高，低高压水喷射系统，高的时候，双方电机输入功率，因此，提出了高，中，低三个康复计划执行情况的部分压力。在转型过程中，5个注水压力柱塞泵的吸气压力维持高于15兆帕斯卡6注水井;在三柱塞泵2＃，3＃，4＃泵为中高压注射泵，在为了少于15 7注水井兆帕斯卡吸入压力，以1＃3作为一个低高压注射泵泵活塞泵小于2.5兆帕斯卡的压力的吸力注水井，而里面的水流量站外站的管网已转变。

转变，从联合水停止后分为三个压力水平，节能效果立即显现出来，：平均单耗由一个高压喷射泵装置七点五五千瓦时/米下降至4.03千瓦时/立方米，日日水平四○九七千瓦时电力，每1千瓦时/平方米为2622元，每天0.64元，可节省资金;改造投资25.00万元，投资回收期为只有4个月。同样，大港油田采油立即在所有宣传机器，现在8点注射节能的水分压的技术改造。
