Title
THE DISCOVERY OF TAHE OILFIELD AND ITS GEOLOGIC IMPLICATION
摘要
塔河油田是由三叠系、石炭系、奥陶系等多个不同性质油藏组成的油田(群),主体是奥陶系灰岩岩溶缝洞网络型油气藏。这种油藏类型的主要控制因素是不同期次、不同规模、不同方向的岩溶洞、缝、孔,并以复杂的形式联通而形成网络。因为网络发育程度不同、成藏和改造经历不同,各储集体在储量、产能、油质上可有较大差别。
Abstract
Tahe Oilfields is composed of different ages of reservoirs such as Triassic,Carboniferous and Ordovician reservoirs.The main part is the network consisting of karst cracks and holes in Ordovician limestone reservoir.Its controlling factors are karst holes,cracks and pores which formed quite different in size,time and extending direction and connected into nets in very complicated ways.The reservoirs vary in reserve,productoin capacity and oil quality due to the different levels of net developing and history of reservoir forming.
