摘　　要：川中地区合川—潼南区块须家河组气层,由于含高束缚水和黄铁矿,造成气层电阻率很低,属典型低阻气藏。在该区用常规测井资料难以准确识别储层流体性质。通过分析低阻油气藏形成的原因,提出了利用阵列感应和核磁共振测井评价储层流体性质的方法,实际应用取得了良好效果。Xujiahe gas layer,Hechuan-Tongnan block of Central Sichuan Basin,is a typical low-resistivity reservoir because rich high-irreducible water and pyrite can be found resulted in an extra low resistivity.It is very difficult to accurately distinguish the fluid property by means of conventional well-logging data.In this paper,some causes to form low-resistivity reservoir are analyzed;and then to use array induction logging and NMR to evaluate fluid property is presented;at last,a better application result has been obtained.
