摘要 通过大港滩海关家堡地区的油气控制因素分析及有利区块的评价,取得了3点主要认识:①三种控藏因素,即有桥梁及纽带作用的地层不整合面、断层控制油气的纵向运移及分布、不同类型的输导网络控制油气的分布;②三种油气成藏模式,即斜坡带阶梯状成藏模式、断层与次级断层组成"Y"字形成藏模式、次级小断层成藏模式;③三种数学地质评价方法(地质风险概率法、模糊数学评判法、专家系统方法)综合评价认为D18断鼻→庄海4X1断块→庄海8井区→庄海808X1并区油藏依次变差。 The study of the main controlling factor on hydrocarbon accumulation and evaluation on the favorable block has been con- ducted for Guanjiapu district in Dagang Beach District. Three main understandings have been achieved. Firstly, there are three main controlling factor on hydrocarbon accumulation, including unconformable surface, faults and the combination of hydrocarbon trans- portation layer. Secondly, three hydrocarbon accumulation models have been established, including ladder accumulation model. In the slope zone, "Y"front style accumulation model. And the secondary fault accumulation model. Thirdly, three geologic evaluation methods (geologic risk stochastic method, fuzzy mathematic evaluation method, and expert system method ) have been developed for Guanjiapu district. Through comprehensive geologic evaluation, it is concluded that from D18 faulted nose to Zhuanghai 4X1 Fault Block, Zhuanghai Well block-8, Zhuanghai Well block 808X1, the reservoirs become poor gradually in Guanjiapu district.
