摘要
塔河油田已经开发的区块不同程度地含有硫化氢和二氧化碳气体,有些区块含量极高,硫化氢和二氧化碳气体对电缆和钢丝造成严重的腐蚀断裂,使得压力计等设备落入井内,后果十分严重。投捞式压力计试井工艺技术具有抗腐蚀、不用起下油管、不受测试时间限制、投放深度准确灵活等特点,提高了测试的安全性和可靠性,很好地解决了含硫化氢和二氧化碳井试井难的问题。
There are H2S and CO2 in the oil produced from some blocks of Tahe Oilfield,and the contents of H2S and CO2 in the oil produced from several blocks are very high.Cable and wireline can be easily corroded and so ruptured by H2S and CO2,which causes serious results of dropping into the well of pressure gauges and other devices.Well test technique of pressure gauge with pulling and running tool has the virtue of corrosion resistance,and besides,it is not necessary to run in and pull out tubing,no limitation of test time,and the depth of the tool can be controlled accurately and easily.This technique improves the safety and reliability of test operation,and so solves the problems of well test in sour wells.
