摘　　要：陆相断陷盆地岩性圈闭目标的快速识别和优选,需要先进地质理论指导与地震技术应用两方面的有机结合。本文通过对塔南凹陷岩性油气藏快速勘探过程中使用的地质理论和地震技术进行总结,建立了一套复杂断陷盆地岩性油气藏快速探明储量规模的实用地质一地震配套技术系列。在岩性油气藏勘探程度不断加深的过程中,综合采用构造分析、层序分析、相带分析和成藏分析等地质分析方法进行指导,配合使用精细构造解释、地震多属性分析、井—震约束下的拟声波波阻抗反演等地震技术,实现岩性圈闭的"定背景、定层系、定区带和定目标",有效地解决了塔南凹陷岩性油藏勘探中遇到的地质难题,在较短的时间内实现了岩性油藏勘探的突破和基本探明。这一技术系列对同类断陷盆地岩性油气藏的勘探具有重要的借鉴和指导意义。That how to identify and optimize lithology traps in fault basin quickly and improve exploration efficiency needs the guidance of advanced geology theories and the application of seismic technologies jointly.This paper creates a practical geologicseismic technology series for rapidly finding the scale of proved oil and gas reserves of lithologic reservoirs in complicated fault basin through summarizing the geologic and seismic technologies used during lithologic reservoirs exploration in Tanan sag,Tamsag Basin.In the series,in order to determine the structural background,formations,zones and traps developed for oil and gas accumulation in lithologic reservoirs,different emphasis should be focused on structure,stratigraphic sequence,sedimentary facies belt and accumulation condition analysis,using together with fine structure interpretation,seismic attribute analysis and seismic wave impedance inversion,in different exploration stage.The technology series solve many geological problems and achieve a breakthrough during lithological reservoirs exploration in a short time,and can also be used to direct lithologic reservoirs exploration in similar fault basin.
