THE FORMATIVE CONDITIONS OF THE COAL GAS OF WANGJIAHE GAS FIELD, KAIPING SYNCLINE

North China Bureau of Petroleum Geology, Ministry of Geology and Mineral Resources

摘要: 王家河气藏是一典型的、非常规的煤成气藏。本文对这一气藏的形成条件,包括气源、储集、盖层、圈闭以及形成时间等进行了分析,指出王家河煤成气藏气源充足,属多种圈闭的构造裂隙气藏,气藏最终完成于第四纪。

Abstract: Wangjiahe Gas Field is a typical nonconventional coal gas pool. The formative conditions for such a gas pool, including the source of the gas, reservoir, cap, trap and its timing are studied and analysed. It is hoped that this presentation would call forth valuable opinions on searching of coal gas, especially the thin seam coal gas.
