Abstract

Abstract:

The composite foreland basin in western Sichuan has undergone multiple tectonic conversions and sedimentary migrations since Late Triassic. Such tectonic settings with multi-phase and multi-boundary activities resulted in multiple sedimentary provenances as well as the diversity and superimposition of sedimentary system. The Upper Triassic-Jurassic clastic reservoirs are typical low-porosity and low-permeability tight to ultra-tight sandstone reservoirs with average porosity lower than 10 % and average permeability less than 0.1 mD, dominated by nanometer pore-throat. The reservoirs are distributed from mid-shallow layers to deep layers. Different types of multi-layer reservoirs are composite and superimposed vertically, while multiple sets of reservoirs were widely superimposed with laterally continuous distribution, presenting significant superimposition and extensive coverage. The reservoirs show extremely strong vertical and lateral heterogeneity in terms of rock components, pore space types, petrophysical properties, pore structure characteristics, petrophysical lower limit for reservoir formation, and etc. The reservoir formation and evolution occurred in multiple phases, and continuous effective reservoirs could be formed in each bed series or horizon. Generally, reservoirs present the reservoir-controlled characteristics of "provenance, sedimentation-diagenesis and structure-fault". Meanwhile, there are different key factors for favorable reservoir development in various horizons. The distribution of favorable reservoirs can be comprehensively and quantitatively predicted on the basis of rock types, sedimentary facies, quantitative diagenetic facies, fault characteristics and other research results.

Key words: tight sandstone reservoir, provenance, sedimentary facies, diagenetic facies, porosity evolution, superimposed tight sandstone gas area, western Sichuan depression

摘要：

川西复合前陆盆地自晚三叠世以来经历了多次构造转换与沉积迁移,多期次、多边界活动的构造背景造成了沉积物源的多源性以及沉积体系的多样性和叠合性。上三叠统至侏罗系碎屑岩储层平均孔隙度<10 % ,平均渗透率<0.1 mD,纳米级孔喉占主体,是典型的低孔低渗致密—超致密砂岩储层。储层分布范围从中浅层至深层,纵向上多层系不同类型储层复合叠置,平面上多套储层大面积叠合连片分布,呈现明显的叠合性和广覆性。储层在岩石组分、储集空间类型、物性特征、孔隙结构特征、成藏物性下限等方面具有极强的纵、横向非均质性。储层形成演化具有多阶段性,各个层系或层段均可形成规模有效储层。储层总体表现出"物源、沉积-成岩、构造-断层"控储的特征,同时不同层段有利储层发育的关键因素有所差别。根据岩石类型、沉积相、定量成岩相以及构造、断层特征等研究成果,可以对有利储层的分布进行综合定量预测。
