摘要

川西坳陷上三叠统须家河组油气资源丰富，是四川盆地主要的致密砂岩气产气层段之一。以川西坳陷须家河组四段(须四段)致密砂岩为研究对象，基于岩石学特征、物性分析和成岩作用的研究，分析须四段砂岩的致密化过程及致密因素，并结合油气成藏史，探究须四段储层的致密-成藏耦合关系。结果表明，造成须四段孔隙损失的主因是压实作用，但导致储层致密的关键因素是成岩系统处于半封闭-封闭状态下沉淀的晚期碳酸盐胶结物，使得须四段相对有利储层在中成岩A期的中、晚阶段砂岩孔隙度降至10 % 以下，对应地质历史时期为早白垩世。包裹体及激光拉曼成分分析表明，须四段具有两个成藏时期，其中处于晚侏罗世—早白垩世的晚期成藏为主成藏期。以储层孔隙度低于10 % 为标准，川西坳陷不同类型储层进入致密演化阶段时，须四段的主成藏期(晚侏罗世—早白垩世)尚未结束，表明须四段储层是“先致密后成藏”型储层。

Abstract

The Upper Triassic Xujiahe Formation in Western Sichuan Depression is rich in hydrocarbon resources and has been one of the major tight gas pay zones in the area. By focusing on the tight sandstone of the fourth member of the formation

this study aims to answer why the stone is so tight and what factors had affected its tightening-up process based on petrological characteristics

reservoir physical property and diagenesis analyses

which are also combined with hydrocarbon accumulation history to confirm a possible coupling relationship between the two processes. It reveals that compaction caused great porosity loss in the stone. However

it was the late-stage precipitation of carbonate cements in a semi-closed to a closed setting that played a key role in the process by reducing the porosity of high-quality reservoirs in the formation to less than 10 % during the middle and late stages of mesodiagenesis (corresponding to the Early Cretaceous). Fluid inclusions and laser Raman compositional analyses suggest two hydrocarbon accumulation periods

of which the second period (the Late Jurassic-Early Cretaceous) contributed more. It also suggests that when other types of reservoirs in the basin were entering the tightening-up stage

i.e. when their porosity was reduced to less than 10 %

hydrocarbon accumulation in the fourth member of Xujiahe Formation was still ongoing

indicating a precedence of reservoir tightening to hydrocarbon accumulation.
