王庄地区地层油气藏形成条件及分布规律

近年来。王庄地区地层油气藏勘探获得重大突破，相继发现了太古界、古生界、沙三段、沙一段和馆陶组等多套含油层系。油藏类型有原生砂岩体(岩性上倾尖灭和透镜体)油气藏、地层不整合遮挡油气藏、超覆不整合遮挡油气藏和生物礁块油气藏等。成藏条件分析表明。处于盆地边缘的王庄地区发育多种地层圈闭和两种输导体系。对于它源型油气藏来说。输导体系起着至关重要的作用，油层多沿输导层分布。形成上下叠置的复式地层油气藏。

Forming conditions and distribution law of stratigraphic hydrocarbon reservoirs in Wangzhuang area

In recent years, exploration breakthroughs of stratigraphic hydrocarbon reservoirs have been made in Wang zhuang area. Series of oil - bearing strata were discovered successively in Archaeozoic, Palaeozoic, Es3, Esl and Ng, including primary sandstone (lithologic updip pinchout and lens) reservoir, stratigraphic unconformity screened reservoir, unconformability of lap screened reservoir, and reef hydrocarbon reservoir. The analysis of reservoir forming conditions shows that, many types of stratigraphic traps and two types of transport systems had developed in this basin edge area. For else - source reservoirs, the transport system plays an important role. Oil reservoirs are likely to distribute alone transport layer, forming superimposed complicated stratigraphic reservoirs.
