摘　　要：在地层水化学分析、气水层的识别的基础上,对苏里格气田苏54区块气水的分布特征及分布规律开展深入研究。区块东部基本不产水,其余区域均有地层水的存在,并且在一定程度上具有连片分布的特征。2012年在东部筛选不产水的区域集中,Ⅰ+Ⅱ类井比例达到72.0%,平均无阻流量10.6×104m3/d,2口水平井试气均达百万方,开发效果良好。The characteristics and the law of the gas-water distribution in the studied area are studied based on the chemical analysis of the formation water and the identification of gas/water layers. It is shown that, almost no water is produced in the east of the block, in the other areas of the block there is all formation water, the areas are characterized by continuous distribution to a certain extent. In 2012, the areas without producing water are selected. I ＋ II type of wells accounts for 72.0%, their average open flow rate is 10.6x 104m3/d. Of these, the test gas yield of 2 horizontal wells reaches to million cubic meters. A good development result is obtained.
