苏南区块下古生界气井产水岩石测井学原因初步评价研究

Preliminary study on the causes of water production in the palaeozoic gas well in sunan block

本文从马五4段白云岩体分布和储层特征入手;在应用马五4段产层判识标准对单井储层流体识别的基础上;以气水分布剖面为手段研究了工区的气水分布特征;分析得出了工区的气水分布规律和控制因素;结合地层水的水化学资料;预测了工区的气水分布。

This paper starts with the distribution and reservoir characteristics of baiyun rock mass in the five and four sections of the horse.On the basis of the identification standard of different production layers on the fluid identification of single well reservoir;The distribution characteristics of gas and water in the working area were studied by means of gas-water profile.The distribution law and control factors of gas and water in the working area were analyzed.Combining the hydrochemical data of formation water;The distribution of gas and water in the industrial area is predicted.
