四川盆地西部中三叠统储层特征与类型
Characteristics and Types of Middle Triassic Reservoir in Western Sichuan Basin
摘要
Abstract
Based on the data of drilling wells and well logging, this paper studied the reservoir rocks, pore types and physical property of middle Triassic in western Sichuan Basin, dividing the reservoir types, and then pointed out the controlling factors for the reservoir development. The good reservoir in Middle Triassic (Leikoupo Formation) in western Sichuan Basin concentrates in segment 3, and the reservoir rocks are chiefly diverse grain dolostone and algae-bounding dolostone. Their main reservoir spaces are various dissolution pores, such as interparticle solution pores and intraparticle solution pores. The Middle Triassic reservoir can be divided into three types, which are (reef) bank-facies dolomite reservoir, karst reservoir and hydrothermal dolomite reservoir. Their development are mainly controlled by deposition, diagenesis and tectonic action (uplifting and faulting).关键词
