| 摘 要： | 在油气井加砂压裂施工作业中，常遇到一井多产层压裂问题，按常规方法进行逐层压裂，不但工期长、不安全，还会对油气层造成再次污染。分层及选层加砂压裂工艺，是通过下入联作管串，在地面投球开启或关闭井下转层器，实现对油气层进行选层或分层加砂压裂的目的，压裂后进行多层分采。

| Abstract: | In the sand fracturing process,multilayer fracturing problem is often meet. Traditional method is fracturing layer by layer,this need to spend a long time, lot of money,damage the formation many times and have low safty.Laying and selecting layers fracturing can be performed by using tubing string and through ball to control layering and selecting. The oil fie1d application provided that this kind of technology is beni fit in oil field. |
