摘要

近年来,埕岛地区潜山勘探取得了重大进展,构造和储层条件控制了潜山油气的成藏和富集程度。通过对该区构造演化、储层的控制因素及其分布规律进行研究,进一步明确了潜山的构造演化过程对地层分布以及储层分布规律的作用。研究发现,埕岛潜山经历了长期的风化剥蚀和多期复杂的演化历程,储集空间类型多样,风化壳储层是潜山主要储集体,随着从风化面向下深度的增加,储层发育程度逐渐降低,内幕储层也有一定程度发育,内幕断层控制其分布。对埕岛油田潜山下一步勘探及渤海湾盆地潜山勘探有借鉴作用。

Abstract

In the past few years,great achievements have been made in the exploration in the buried hill reservoir of Chengdao.Structure and reservoir conditions control the accumulation and enrichness of oil and gas in the buried hill.This paper studies the structural evolution,the controlling factors on reservoir and its distribution and demonstrates the role of structural evolution of buried hill on the distribution of strata and reservoirs.Results indicate that the Chengdao buried hill experienced long time weathering denudation and multiple complex evolution.Reservoir space has great diversity and the weathering crust reservoir is the dominant reservoir in the buried hill.As the depth to the weathering front increases,the development of the reservoir decreases and inner buried hill reservoirs increases which is controlled by interior fault.This paper can provide some references to the exploration of the buried hill in Chengdao region as well as the Bohai Sea Bay basin.
