摘要：

塔里木盆地阿克库勒地区在奥陶系碳酸盐岩找到了塔河3,4,5号和轮古潜山等油气田(藏)。油气分布:纵向上在潜山风化淋滤岩溶带、渗流岩溶带和潜流岩溶带内,厚约250m左右;横向上在孔、洞、缝发育的古岩溶高地、古岩溶斜坡及不同走向断裂缝交汇处。碳酸盐岩储集层体为裂缝、孔、洞、穴型,断裂缝是流体通道,孔、洞、穴是储集空间。石炭系泥岩是下奥陶统的直接盖层,下奥陶统致密灰岩可作为非渗透性封挡层体。海西晚期是圈闭形成的主要时期。油气藏类型为潜山风化壳与裂缝、孔、洞、穴复合型底水油气藏。全面勘探开发该区,有望实现石油工业“稳定东部、发展西部”的战略目标。

Abstract:

Oil and gas fields such as Tahe 3,4,5 and Lunnan buried hill were found in the Ordovician carbonate rocks in Akekule region,Tarim Basin.The oil and gas are mainly distributed in the weathered crust and leaching zones of buried hill,vados and underflow karst with the thickness of 250 m;in paleo karst highland and slopes,the convergent places of fualts and fractures.The carbonate rock reservoirs are fracture,cave and hole types;the Carboniferous mudstone is the cover of the lower Ordovician,the Lower Ordovician dense limestone is impermeable sealing bed,and Late Hercynian is the main pool-forming stage.

Key words: Tarim Basin, Akekule region, Ordovician carbonate rock, oil and gas prospects
