博兴地区油气成藏系统研究

Study on oilgas reservoir forming system in Boxing area.

博兴地区发育多种类型的圈闭 ,油气资源丰富 ,是一个复式油气聚集区。该区油气有两个成藏期 ,即东营组沉积末期和明化镇组沉积时期。提出油气成藏系统概念和划分原则 ,并将博兴地区划分为西部高青断裂带、南部樊家—正理庄—金家斜坡带、东部纯化—梁家楼和北部小营—平方王四个油气成藏系统 ,不同系统具有不同的油气成藏特征和成藏模式。

Boxing area is a complex oilgas accumulation one with many types of developed traps and abundant hydrocarbon resources. There are two reservoir forming stages including the late Ed sedimentary period and Em sedimentary period in this area. In this paper, the concept of oilgas reservoir forming system and dividing principle are presented. Boxing area is divided into four oilgas reservoir forming systems including the west Gaoqing faulted zone, the south FanjiaZhenglizhuangJinjia slope belt, the east ChunhuaLiangjialou and the north XiaoyingPingfangwang. Different system has different oilgas reservoir forming character and model.
