长6油藏开发特征对比及稳产技术研究

自上世纪90年代采油三厂油藏开发重点由侏罗系向三叠系转移以来,相继快速有效地开发了五里湾、盘古梁、吴仓堡等三叠系长6油藏,目前三叠系长6油藏探明地质储量占全厂储量的73.7%,占全厂产量的66.3%。重点总结对比了五里湾、盘古梁、吴仓堡等已开发长6油藏的递减规律、含水上升规律、压力上升规律等开发特征,并在此基础上提出了长6油藏的稳产技术对策。

Research contrast development features and stability technology of chang 6 reservoir

Since the 1990s,the third factory of oil production which had transfered the focus from the jurassic to triassic have developed some triassic's chang 6 reservoir such as wuliwan、panguliang and wucangbao.at present,prevented geological reserves on triassic's chang 6 reservoir take a 73.7%of the whole factory and take a 66.3%of the factory's yield.the article have aggregated and contrasted some developed chang 6 reservoir such as wuliwan、panguliang、wucangbao and their features which include the law of diminishing、increased moisture and increased pressure.and then,on the basis of this point,we proposed the countermeasures to the stability technology of chang 6 reservoir.
