摘要

随着油田开发的不断深入,老构造解释与新资料的不符逐渐显示出来,利用地质、地震、测井等多种手段和方法对断层进行重新识别、组合,使其更符合现有各种静态和开发资料;研究表明主要的微构造类型为微鼻状、微断鼻、微沟槽构造,且大部分具有继承性;微构造主要是由断层的不平衡运动、断层走向的突变,以及沉积体厚度变化造成的差异压实作用形成;正向微构造开发状况好,剩余油富集,并且位于正向微构造的高部位略好于其翼部。
With the continuous deepening of oilfield development,the old structure interpretation inconsistent with the new information gradually became apparent,In this paper,we used geological,seismic,logging and other means and methods to re-identify and combine the faults,Make it more in line with the static and the development of existing information;Studies have shown that the major type of micro-structure are micro-nose,micro-broken nose,micro-groove construction,And most have inherited;Micro-structure mainly causes by the unbalanced fault movement,fault direction of mutation,and the sediment thickness differences caused by changes in the formation of compaction;Positive micro-structure have good development status and enrichment remaining oil,located in the high positions of positive micro-structure is better than its wings.
