摘要
哈山地区处于盆缘斜坡构造背景,经多期构造运动,地层超剥关系复杂,主要发育超覆-削蚀油藏,圈闭识别难度较大。本文通过对不整合面的精细刻画、超剥点的准确识别,建立了一套适合超剥带圈闭识别方法,并在研究区发现并描述了大量的圈闭,为哈山南缘浅层超剥带下步勘探提供了有利的勘探目标。哈山地区近年探井相继钻探成功证实了此圈闭识别方法对哈山勘探开发具有重要的指导意义。
HaShan area is located in slope of basin border,and suffered tectonic movement of multiple phase,which has complex overlapping denudation relationship with main development of unconformity reservoirs,so trap identification is difficult.And through unconformity surface depiction and exact identification of overlapping denudation point,a set of method to suit the ultra peelable strip trap characteristic recognition is established,and we find lots of traps,and provide favorable exploration targets.In recent years,many successful drilling wells confirmed the trap identification method on HaShan exploration and development,which has an important guidance in HaShan area.
