摘要
强边底水稠油油藏在稠油油藏中占有很大的比例,这类油藏开采难度较大,边底水水侵导致热采效果差、开发效益低,需要在各开发阶段开展控水稳油措施。在低含水期,制定合理的采液速度;中高含水期,实施非烃类气体复合热采技术和化学复合热采技术;高含水期,通过深部多级堵水热采技术达到控水的目的。
Heavy oil reservoirs with edge and bottom water account for a large proportion of heavy oil reservoirs.These types of reservoirs are difficult to exploit.The water encroachment from the edge and bottom water leads to poor thermal recovery effects and low development efficiency.Therefore,water control and oil stabilization measures need to be carried out in each development stage.During the low-water-cut period,a reasonable fluid production rate should be formulated.In the medium-to-high-water-cut period,non-hydrocarbon gas composite thermal recovery technology and chemical composite thermal recovery technology should be implemented in advance.In the high-water-cut period,the goal of water control can be achieved through deep multi-stage water-plugging technology.
