摘　　要：通过对正理庄油田火成岩圈闭形成条件、油藏成因等分析研究,确定出该区有四种火成岩遮挡的成藏类型;应用构造地质剖面图、火成岩底面构造图和砂层顶面与底面构造图等,圈定出火成岩遮挡的圈闭范围,并结合电测、试油试采与开发动态等资料,确定出火成岩遮挡油藏含油范围,计算了石油地质储量。Through analysis and study on encirclement-forming condition and oil deposit origin of Zhenglizhuang magmatic rocks, four types ore deposits are determined in this area. By using tectonic and geological profile map, lower surface tectonic sketh of magmatic rocks and tectonic sketch of upper and lower surfaces in sand stratum, encirclement scope screened by magmatic rocks is circled. Combing with electrical measuring, oil-exploration experiment and dynamic exploration information, oil-bearing scope of oil deposit screened by magmatic rocks is determined, and geological reserve of oil is measured.
