河南油田环空测压工艺已在40余口井上应用。经现场试验主要出现以下几个问题: 1.原油凝固点高,油套环形空间在一定深度出现蜡环,使压力计起下困难,测不出压力恢复曲线。
Henan Oil Field Central Manometry has been applied in more than 40 wells. Mainly through the field test the following questions: 1. Crude oil freezing point high, oil ring in a certain depth of the annular space appears wax ring, so that the pressure gauge from the next difficult to measure the pressure recovery curve.
