利用PNN测井远近计数率曲线识别井筒积液面

IDENTIFICATION OF WELLBORE FLUID SURFACE WITH PNN LOGGING DISTANCE COUNT RATE CURVE

一直以来随着气田的不断开采,气井出水量呈现增多的趋势,井筒存在积液逐步成为影响气井产能的一项很严重的问题。本文通过对PNN测井原理及近计数率的研究分析,找到了一种识别气井积液面的新方法。

With continuous exploitation of gas field, water yield showed a increasing trend. Wellbore fluid gradually becomes a serious problem which affects the gas well production capacity. In this paper, through the study of PNN logging principle and nearly count rate analysis, a way is found to identify the fluid in gas wells.
