塔里木盆地沙雅隆起雅克拉断凸储层储集性研究及评价

雅克拉断凸下古生界以碳酸盐岩为主,主要储集空间类型为晶间孔及晶间溶孔、溶蚀孔洞、大型洞穴、风化裂隙,形成岩溶缝孔洞型储层、溶蚀孔洞型储层、岩溶洞穴型储层。其中以岩溶缝孔洞型储层为主。本文利用岩心观察、钻井资料、物性资料等综合分析岩溶缝孔洞型储层发育的有利区域,得知雅克拉断凸中部为该储层最为发育区。

Research and Evaluation of reservoir of Yakela Block in the Northern Tarim Basin

Reserviors in the Lower Paleozoic are dominated by carbonate rocks in Yakela Black.There are five types of storage spaces such as intra-crystal Pores and intra-crystal soluble pores,solution pores,large caves,weathered fissures.They can form the fractured-cavernous-type reservoirs,solution pores-type reservoirs,cavity-type reservoirs.And the fractured-cavernous-type reservoirs are the main.In this paper,it takes advantage of the Core observation,drilling data and Physical data to analysis the favorable regions of development of fracturedcavernous-type reservoirs,It shows that in the central of Yakela Block is the best.
