BZ34-3／5小边际油田的开发模式和电潜泵采油技术的应用

开展海上边际油田的开发研究是开发海上油田的三大技术难题之一。BZ34-3／5油田是渤海海域的小边际油田，针对该边际油田“现有油田附近含油构造”特点采用了“三一”开发模式和两腿三桩轻型平台，并且采用了一井双泵采油技术，自投产以来日产油达300多立方米，这标志着该海上小边际油田建成并成功投产，达到了预期的目的，并取得了较好的经济效益。该油田的开发和开采模式对于边际油田的开发具有普遍意义，因此简要介绍了该油田开发模式和电潜泵采油技术的应用。

Models of exploiting the small marginal BZ34-3/5 oil field and application of ESP to well production technology

BZ34-3/5 oil fields are small marginal oilfield in the Bohai Bay. According to their characteristics, in order to save cost oil produced here was sent to a nearby well-developed oilfields using one simple platform with 2 legs and 3 piles, one seabed pipe, and one seabed cable. Meantime dual electric submersible pump was used here. Daily output reached 300m^3, which showed that these two oil fields had been constructed successfully and put into production. It achieved the anticipated goal and significant economic results. Therefore, the development models of small marginal oil field and the application of ESP were briefly introduced in this paper.
