摘　　要：为了准确落实构造,克服单一采用地震或测井解释进行构造成图的局限性,本文针对目前老油田在构造研究中存在的问题,有机结合测井解释和地震解释的优点,提出了一种油田开发阶段的全三维地震解释技术的思路与流程,包括测井构造研究、测井层位深度建模、常规三维地震解释、全三维地震解释、研究区变速场建立、高精度变速场构造成图以及有利区块分析和井位部署等技术.该技术在大港唐家河油田构造研究中取得了很好的效果,在勘探开发程度很高的港深18-2断块东侧发现了一个圈闭面积为0.8km2的GS18-2东断块,推测为含油断块,建议部署两口探井.In order to accurately identify structures and to overcome the limitation of structure mapping with seismic or logging data separately, a set of ideas and procedures of full 3D seismic interpretation for oilfield development is developed, which aims at several problems occurred during structural research of old oilfield and makes use of the advantages of combination between logging and seismic interpretations. It is composed of several techniques such as log structure researching, log layer_depth modeling, conventional 3D seismic interpretation, full 3D seismic interpretation, various velocity modeling, high_accuracy structure mapping, favorable block evaluation and well location design. These techniques have been applied to structural research in Tangjiahe oilfield and have made a good result,i.e.the GS18?2E fault block with a trap area of 0.8km 2 is found along the east side of GS18?2 fault block with mature exploration,and it is proposed to drill two exploration wells in the fault block.
