摘要
文南-刘庄地区处于东濮凹陷中央隆起带北部的南部倾末端,东、西紧邻生油洼陷,储、盖组合配套,油气富集务件优越,勘探潜力较大,解剖区域内探明油气藏类型归纳为构造型与复合型油气藏两大类,依据构造样式及岩性变化作用程度细分为地垒式、地堑式、反向断块式和构造-岩性、岩性-构造5种类型,深入分析该区运聚与富集规律共划分为正向地垒构造样式双向运移、负向地堑构造样式单向运移、断节构造样式双向运移和单斜构造样式单向运移4种油气成藏模式,在此基础上深化研究取得了明显的勘探效果.
Abstract
Wennan-Liuzhuang lies in the southern (lipping end in the north of central uplift zone of Dongpu Depression, closing to the oil generation sag on the east and the west. The reservoir-seal association forms a complete system and the hydrocarbon accumulation condition is well It has an attractive exploration prospect The proved regional reservoir types consist of the structural reservoir and complex reservoir. According to the structure and lithology, the reservoirs can be subdivided into five types, including horst, graben, reverse faulted block, structure-lithology and lithology-structure. Further analysis shows that there are four types of reservoir-seal associations, namely dual migration of normal horsl structure, single migration of reverse graben structure, dual migration of faulted structure and single migration of monoclinal structure, in which the detailed study has got the obvious effects in exploration.
