平北探区是平湖油气田之后,又一重要的勘探开发基地。本文在二维、三维地震资料解释的基础上,分析了该区的构造特征和类型,结合钻井揭示的地层、沉积相和油气地质资料,对东、西部两个构造带的生、储、盖条件进行了探讨,认为平北探区的东部构造带优于西部构造带,其主要勘探目的层——平湖组具备了油气聚集的基本条件,可形成高产油气藏。

PingBei area is another important base for exploration and development besides PingHu petroleum field. Based on 2-D and 3-D seismic data interpretation, the structural type and characteristic of the area were analyzed in this paper. Integral with drilling data, depositional facies and petroleum geological condition, we learned the source, reservior and caprock of the eastern and western structural belts. The eastem structural belt is more promising than the western structural belt. Pinghu Formation-the main target stratum, is advantageous for petroleum accumulation and highly-productive pool.
