摘　　要：在小层细分、沉积、储层研究的基础上,充分利用气水分析化验和试采资料,系统分析了须二气藏气水特征。认为蓬莱地区须二气藏气水分布主要受控于储集体和构造位置,单个储集体内气水总体具有"上气下水"特征、优质储层发育的地区含气性好;气层主要分布在距须二段顶界90 m以内的T3x24、T3x25砂层组,下部T3x21、T3x22和T3x23砂层组主要为气水同层。The gas-water relation in Xujiahe 2 gas reservoir(T23x) is analyzed by experimental and production-test data based on some study on the sub-layer subdivision, deposition,and reservoir. Results show that(1) for the T3x2 in Penglai area, the gas-water distribution is mainly affected by reservoir body and tectonic position;(2) in a single reservoir body, the gas-water relation generally appears a feature of upper gas and lower water;(3) better gas content can often be found in one area with developed high-quality reservoir;(4) gas is dominantly from both T3x24 and T3x25sandstones, which are within 90 m from top T3x2;and(5) the T3x21, T3x22, and T3x23 sandstones are mostly gas-water zones. So, it is significant to clarify this gas-water relation in Xujiahe 2 reservoir for its further E & P.
