摘要:
水平井是渤海Q油田开发后期的主力井型，但水平井进入高水期后，控水、防砂难度大。近年来，渤海油田先后采用了变密度筛管、中心管等技术来控水，但效果欠佳，为此提出了环空阻流控水技术。该技术能实现精细分段控水，鉴于此技术的控水原理，对渤海Q油田的180口水平井进行数据统计分析，归纳总结出油田中水平井含水上升规律和水平段出水类型，确定控水防砂效果评价指标ΔR/Δfw（产油效率），利用灰色关联确定其主控因素，在此基础上制定适宜该项技术的选井原则，为技术成功实施奠定基础。在渤海Q油田，应用该技术对3口水平井进行了控水防砂措施，效果显著。现场实践证明，该技术控水、防砂效果显著，该技术以及选井原则具有推广应用价值。
Abstract:
Horizontal wells are the main well type in the late development of Bohai Q Oilfield，but it is difficult to control water and sand after horizontal wells enter the high water-cut stage. In recent years，the technologies such as variable-density screen tubes，central pipes have been adopted to control water in Bohai Oilfield，but the effect is not good. Therefore，an annulus blocking flow control water technology is proposed，which can realize fine segmented water control. According to the water control principle of this technique，it was carried out the data statistical analysis of 180 horizontal wells in Q Oilfield，and it was summarized the laws of water-cut rising and the types of water production in the horizontal section. And then it was determined the water and sand control effect evaluation index （ΔR/Δfw，oil production efficiency）. Using gray correlation，the main control factors were determined. On this basis，it was formed the well selection principle suitable for this technology，which lays the foundation for the successful implementation of the technology. In Bohai Q Oilfield，this technology was applied in 3 horizontal wells for water and sand control，and the effect was remarkable. The field application confirms that the technology has significant effects on water and sand control，and the technology and the principle of well selection have broad application value.
