prefrac flow

To the problem of the formation not producing water at pre-fracture and producing water at post-fracture,it is very important that the forecast at pre-fracture time for producing water layer of the well whose oil productivity is smaller than that at pre-fracture because of too much of water production.

针对压裂前测试不产水、压裂后地层产水;由于产水量过大,产油量比压裂前还低的井进行压后产水层的压前预测十分必要。
