摘要

川西新场气田蓬莱镇组次生气藏为岩性气藏，在蓬莱镇组砂、泥岩中，砂岩为最主要储层。通过对该气藏进行沉积相、储层及气层地震响应等特征的详细研究后，认为控制储层储集性好坏的主要因素是沉积微相。气藏内有利储集砂岩多属三角洲前缘河口砂坝、三角洲平原分流河道砂坝及河流相河道砂坝微相。有利储集砂体展布即与这三种微相展布一致
The secondary pools in the Penglaizhen Formation in the Xinchang gas field,western Sichuan are believed to be lithologic gas pools.The sandstones are considered as the main reservoir beds in the sandstones and mudstones of the Penglaizhen Formation. The detailed studies of sedimenary facies of the gas pools,and seismic response of reservoir beds and gas beds indicate that sedimentary microfacies are the main controlling factors on reservoir quality.The favourable reservoir sandstones in these gas pools may broadly be assigned to the deltaic front channel mouth bar,deltaic plain distributary channel bar and fluvial channel bar microfacies.The distribution of the favourable reservoir sandstone bodies tends to concur with that of the three sedimentary microfacies cited above.
