摘要: 塔里木盆地中—上寒武统广泛发育白云岩储层,但对储层的主要类型、特征和成因机制均缺乏深入研究并存在争议。为了弄清该区储层发育特征和成因,综合利用野外露头、岩心、薄片、钻井、测井及地震资料,运用沉积学、储层沉积学、沉积地球化学等方法开展综合研究,探讨了中—上寒武统主要白云岩储层类型的储集空间特征及控制因素。研究表明,中—上寒武统主要发育有蒸发性潮坪泥—粉晶型、礁滩相-残余结构型、热液-裂缝中粗晶型、表生岩溶-热液叠加型及埋藏-细中晶型5种白云岩储层;各类储层的储集空间、发育演化和分布均受到了沉积环境、白云石化作用、岩溶作用和深部流体改造等多种因素的叠加控制。通过建立礁滩型、表生岩溶-热液叠加型及蒸发性潮坪型等3种有利白云岩储层发育模式,预测了有利发育区。研究成果对塔里木盆地中—上寒武统白云岩储层油气勘探具有借鉴意义。

Abstract: Dolomite reservoirs are extensively developed in Tarim Basin,however,the types,characteristics and genesis have not been research thoroughly and are debated. Based on the data of outcrop,cores,loggings and seismic,the sedimentology,reservoir sedimentology and sedimentary geochemistry were applied to study the reservoir space characteristics and controlling factors of the main dolomite reservoirs in the Middle-Upper Cambrian. The result shows that there are five types of dolomite reservoirs are developed in the Middle-Upper Cambrian,including evaporative tidal flat,reef shoal,hydrothermal fluid fracture,epigenetic karst-hydrothermal superposition and burial type. The reservoir spaces,development and distribution were controlled by depositional setting,dolomitization,karstification,deep fluid reformation. Three favorable types of dolomite reservoir development models were established,such as reef shoal type,epigenetic karst-hydrothermal superposition type and evaporative tidal flat type,and the favorable developmental areas were predicted. The research results have reference significance for the oil and gas exploration of the Middle-Upper Cambrian dolomite reservoirs in Tarim Basin.

Key words: depositional system, high-resolution sequence framework, Jurassic-Paleogene, Turpan-Kumul Basin
