川中下侏罗统大安寨组储层特征及控制因素
Reservoir Characteristics and Controlling Factors of Da’anzhai Member in Lower Jurassic,Central Sichuan
摘要
Abstract
Based on the lithology characteristics of the drill cores,outcrops profile,and thin slice observation,X-diffraction, isotopic analysis,CT-Scanning,and so on in the central of Sichuan Basin,we studied the reservoir of Da’anzhai Member in lower Jurassic in the paper. The Da’anzhai Member could be divided into two main kinds of reservoir:crystallized shelly limestone and argillaceous-organic shelly limestone. The main storage spaces include emposieu,intercrystalline gap,intra-shell dissolved pore,periphery gap,inter-shell gap,shelly microfracture,interlamination fracture,tectonic fracture and so on. The reservoir was controlled by sedimentary facies,diagenesis,denudation,tectonic disruption and so forth. Sedimentary facies is the environment basements of reservoir;denudation and tectonic disruption are the key factors that the reservoir could be improved;some diagenesis such as compaction,pressolution,cementation and metasomasis are disadvantages for the reservoir.关键词
