Abstract

Abstract:

The north margin of Kashi Depression is one of the beneficial zones of oil and gas exploration in Southwest Tarim Basin. The Kelatuo Anticline has the most oil gas seepages in north Kashi Depression. Through outcrop description and fine strata section correlation in the east of Kelatuo Anticline, the types of sand body formations and their shapes and distributions and microfacies features were distinguished. The thickness of most sand body is 0115 m and the breadth is 10150 m. The main factors controlling the sand reservoir were analyzed.

Key words: Kashi Depression, Pakabulake Formation, reservoir, characteristics of sand body
