摘要
塔里木盆地雅克拉断凸中西段前中生界下奥陶统-上震旦统岩石类型以发育白云岩、灰岩和灰岩与白云岩之间的过渡类型为主,储集空间可以分为孔隙、裂缝、溶蚀孔洞三大基本类型。根据储集空间类型特征研究区以发育裂缝型储层为主,其次为缝洞型,孔隙型储层发育较少。研究区碳酸盐岩成岩史复杂,表现为中间开启型,成岩演化经历了同生-准同生成岩阶段(海底成岩、大气淡水成岩)、早成岩阶段(浅-中埋藏成岩)、表生成岩阶段再到中成岩阶段(中-深埋藏成岩)的过程,成岩作用主要有压实压溶作用、胶结、交代和充填作用、白云石化作用、溶解作用、碎裂作用等。
The lower Ordovician to upper Sinian series＇s rock types of Premesozoic carbonate reservoir characteristics of middle-western segment of the Yakela faulted uplift, Tarim Basin are main dolomite, limestone and transitional types between them, the reservior space are mainly pores, cracks and solution caves, According to the reservior space＇s characteristics, there are main fractured reservoir, then is the fraetured-vuggy reservoir, while the pore type reservoir is the least in this research area. Carbonate diagenetic history which represented intermediate opening in this research area is complex, diagenetic evolution underwent syngenetic-penecontemporaneous diagenetie stage（Subsea diagenesis and the meteoric diagenesis）, early diagenetic stage （shallow-middle buried diagenesis）, hypergene diagenetic stage to middle diagenetie stage （middle-deep buried diagenesis）, diagenesis are main compaction, pressolution, cementation, metasomatism and filling, dolomitization, dissolution and cataelasm.
