【摘要】 探讨了废钻井液固液分离后再利用的方法,即用经离心机分离后的脱出水与脱出固相再配淡水钻井液、盐水及饱和盐水钻井液。室内实验表明,此方法在技术上是可行的;这种再配的钻井液性能与现场用钻井液和室内按常规方法配制的钻井液性能相近;用脱出固相再配制的钻井液原材料成本只有常规钻井液材料成本的1/6左右。为废钻井液的再利用和解决废钻井液环境污染问题提供了一条可行途径。更多还原

【Abstract】 The effective constituent of waste mud is prepared by centrifugal separation method . It is shown that most of the effective constituent remains in separated solid . The property of mud prepared by both separated solid and liquid is near those of new prepared mud and wellsite mud . It is a practical method to eliminate environmental pollution due to waste mud .更多还原
