Chemical Process and Application of Continuous Foam Drainage Gas Production in Low Production Gas Wells
In order to solve the problem of foam performance and stability during continuous foam drainage gas production in low production gas wells,the effects of different foaming agents,foam stabilizers and defoamers on foam performance were evaluated.By comparing the performance of five common foaming agents,it was found that Tween 80 had excellent foaming ability and foam stability.In the experiment,its foam height reached 10.2 cm,and the foam stability time reached 45 min.Further comparison of the five foam stabilizers showed that sodium chloride could significantly improve the stability of foam and prolong the foam stabilization time to 55 min.In addition,after comparing the five defoamers,it was found that calcium chloride exhibited good defoaming effect,reaching 90%.These research results provide important reference for optimizing continuous foam drainage gas production process in low production gas wells,and help to improve gas production efficiency and economic benefits.
