长堤潜山披覆构造带油气成藏规律分析

<title>alysis on oil-gas reservoir-forming rule in Changdi buried -hill drape structural belt.

长堤潜山披覆构造带发育近岸水下扇、滩坝、扇三角洲、浊积扇和河流相五类沉积体系,油气成藏模式分为构造、地层、岩性、复合四类。从沉积特征分析入手,评价研究其油气成藏规律、资源潜力,对预测披覆构造带油藏分布具有重要意义。

<abstract>e drape structural belt in Changdi buried -hill had developed five sedimentary systems which are near-shore submarine fan, beach bar, fan delta, turbidite fan and fluvial facies. The modes of hydrocarbon reservoir forming may be classified as structural, strati -graphic , lithological and compound ones . From the analysis of the sedimentary features, it is important to predict the oil reservoir distribution of the drape structural belt by studying the pool-forming rules of hydrocarbon and evaluating the potential of the natural resources.
