胜利油田有限公司临盘采油厂监测大队科技人员从生产实际出发 ,经过精心设计 ,反复试验 ,终于研制成功“挂壁式压力计释放器” ,并在现场应用中获得良好的经济效益。注水井压降测试是生产测井工作中的一项重要工艺。为了得到水井的压降曲线 ,压力计下井后需要关井 3ｄ ,测井车 Shengli Oilfield Co., Ltd. Linpan oil production plant monitoring brigade scientific and technical personnel starting from the actual production, after careful design, repeated testing, and finally successfully developed “wall-mounted pressure gauge release” and in the field application to obtain good economic returns. Injection well pressure drop test is an important process in the production logging. In order to get the pressure drop curve of the well, the pressure gauge needs to be shut in after the well goes down
