最佳钻井防污土建结构的设计及应用

设计了一种高效实用的钻井防污土建结构，该结构与原结构相比能杜绝处理渣泥流入废水沉砂池参与废水循环，也可防止废弃钻井液和掏罐泥浆水直接进入沉砂池，因此能更好地控制钻井废水浓度，一定程度上提高钻井废水处理达标率，同时该结构具有对处理水进一步隔油、净化等优点，现场推广应用后得到证实。

Optimum design of construction structure for Drilling wast pollution prevention and its application

A new practical and high effective construction structure of drilling waste pollution prevention has been designed.Comparing with the original structure it has the advantages that it can better control the concentration of drilling waste water and raise the qualification rate of waste water to certain degree and can further divide oil from disposal water and purify the latter because the sludge can be prevented from entering into grit sediment chamber to join in the circulation with the waste water and the waste drilling mud and slurry from washing can not enter into it directly. All above advantages have been confirmed in extended practical application.
