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 2 50m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。
Tarim Basin Akekule area found in the Ordovician carbonate rocks Tahe 3,4,5 and rounds of ancient buried hill and other oil and gas fields (reservoir). Oil and gas distribution: longitudinally in the buried hill weathering and leaching karst, seepage karst and subsurface karst, about 2 50m thick; laterally in the hole, hole, seam developed ancient karst high, ancient karst slopes and different strike Crack intersection. The carbonate reservoir is a fracture, a hole, a hole and a hole, and the fracture is a fluid channel. A hole, a hole and a hole are reservoir spaces. Carboniferous mudstone is the lower caprock of Lower Ordovician, and the Lower Ordovician tight limestone can be used as impermeable seal. Late Hercynian is the main period of trap formation. Reservoir types are buried hill weathering crust, fractures, holes, holes and holes composite bottom water reservoir. The comprehensive exploration and development of this area is expected to realize the strategic goal of “stabilizing the east and developing the west” of the oil industry.
