摘要:

新疆塔河油田上奥陶统良里塔格组主要是一套微晶灰岩和含泥质条纹灰岩地层,属于台地相及台地边缘相沉积。其储层类型包括裂缝型、裂缝-孔洞型和裂缝-溶洞型。储层发育的控制因素主要为良里塔格组CaCO3的含量、早期断裂及岩溶作用的强度。断裂分布区和台地边缘颗粒滩相分布区为好—较好储层分布区。良里塔格组尖灭线以南至桑塔木组初始上超分布线之间的区域是两期岩溶发育区,为中等储层分布区,圈定了912km2良里塔格组有利储层。

Abstract:

Lianglitage Formation of Upper Ordovician is made up of microcrystalline limestone and shale ribbon-bearing limestone which generated in the platform facies and the marginal facies of platform. The types of reservoir include fissure, fissure-hole and fissure-carven. The factors controlling the growth of reservoirs mainly include the content of CaCO3 of Lianglitage Formation, the rifting in early stage, the palaeokarst and sedimentary facies; there were two periods of palaeokarst in Lianglitage Formation between the wedgeout of Lianglitage Formation and the onlap border  of Sangtamu Formation, so the region can be regarded as the middling region for the growth of reservoir,blocking out the region of 912 km2 that is favorable to the growth of reservoir of Lianglitage Formation.The result provides a theoretical base for the oil breakout of Upper Ordovician and the extension of main force pay formation in the south of Tahe oilfield.

Key words: reservoir characteristics, Lianglitage Formation, karstification, Tahe oilfield
