Hydrocarbon Accumulation of Shishugou Group in Cainan Oilfield

Abstract

Abstract: In October, 2002, high-yielding oil-gas flow gushed in C125 Well at Jurassic ishugou group started historical breakthrough in rolling exploration and development of this group in Jundong (eatem Junggar basin） area. Shishugou group is a typical low sistance reservoir with section span of 360 m, thin interbedded sands and great lateral variation, which brings the difficulty for rolling exploration and development. Therefore, further recognition and research of its petroleum accumulation mechanism are of great importance in the next step prospecting. In enns of structure, sedimentary setting and petroleum accumulation, this paper analyzes he reservoir-controlled fac- tors as guide for the next step work.

Key words: Junggar basin, Cainan oilfield, petroleum migration, fault, hydrocarbon accumulation
