摘要:

受理南断层及其派生断层长期不均衡活动的影响,车镇凹陷北部陡坡带发育13个下古生界滑脱潜山,具有形成潜山风化壳油藏与潜山内幕油藏的有利条件,但油气分布规律十分复杂。通过区域地质特征、储层特征和含油气特征研究,认为车镇凹陷北部陡坡带下古生界的油气分布受多种因素控制,生油洼陷烃源岩的最大埋深控制油藏的含油底界,程南派生断层控制油藏的平面分布,碳酸盆岩储层的非均质性控制油藏的垂向分布与富集高产。

Abstract: As a result of the imbalanced activities of Chengnan fault and its secondary fault, there are 13 decollement buried hills in the the Northern abrupt slope of Chezhen sag, which has favorable condition to form the weathering crust and interior reservoirs,whereas the distribution rule of hydrocarlwn is quite complicated.The areal geology, reservoir rock and oil-bearing character of the Northern abrupt slope of Chezhen sag are systematically analyzed in this paper, and it is pointed out that the hydrocarbon distributing of the Lower Palaeozoic is controlled by multiple factorn. The oil-bearing bottom of buried hill reservoirs is controlled by the most buried depth of source rocks of the generative subsags, the horizontal distributing of oil pools is controlled by the imbalanced activities of its secondary fault, and the section distributing and the enrichment and high yield of oil pools are controlled by the developing degree of reservoir rock.

Key words: Chezhen sag, the Northern abrupt slope, the Lower Palaeozoic, secondary fault of Chengnan fault, heterogeneous reservoir
