电潜泵生产井压力监测的新方法

塔里木油田生产井产层在4000～6O00m，均属深井和超深井，转抽后井下压力监测非常困难。在电潜泵下利用永久式电子压力计进行深井和超深井的压力温度监测，已在LN10井试验成功。这种监测方法适合电潜泵机组外径与套管内径间隙较大的井，以便能安装永久式电子压力计。

A New Pressure Monitoring Approach for Production Wells Equipped with Electric Submersible Pumps

The depth of pay zones of production wells in Tarim Oilfield varies from 4000 to 6000 m,which are all classified as deep and ultra-deep wells,downhole pressure monitoring is very difficult after these wells started pumped. The trial at well LN10 has been successful using a technique to monitor downhole pressure and temperature in deep and ultra-deep wells with permenant electronic pressure gauges installed belows submersible pumps, such monitoring technique is suitable for the wells with a large gap between OD of submersible pump system and casing ID, where the permenant electronic perssure gauges are possible to be installed.
