海上底水稠油油藏蒸汽吞吐可行性研究

FEASIBILITY STUDY ON CYCLIC STEAM STIMULATION IN OFFSHORE HEAVY OIL RESERVOIRS WITH BOTTOM WATER

针对埕北油田A31井的开发现状,结合国内外类似油藏开发实例,表明埕北A31井有可能通过蒸汽吞吐改善开发效果,而底水将是影响埕北A31井蒸汽吞吐开发效果的关键因素;然后利用数值模拟方法,预测A31井蒸汽吞吐的开发效果;并在以上综合研究基础上给出了埕北A31井蒸汽吞吐的可行性。

According to the development status of well A31 in ChengBei offshore oilfield and the similar reservoir development cases both home and abroad, the production performance of well A31 can be improved by cyclic steam stimulation, and the bottom water will be the key factor affecting the production results of well A31. Numerical simulation method is used to forecast the development results of cyclic steam stimulation in well A31, and finally, the feasibility of cyclic steam stimulation for well A31 in ChengBei oilfield is proposed.
