复合离子型聚合物重泥浆的初步应用

A Tentative Practice of Compound Ion-type Polymer Heavy Mud

为解决异常高压地区钻井中泥浆密度高,机械钻速低,泥浆处理困难的问题。本文提出了用复合离子型聚合物处理重泥浆的新方法,经室内试验和现场初步实践,取得较好效果,可供现场参考。

In order to solve the problems as high mud density and low penetration rate as well as difficulty in treating mud, meeting with in drilling at the area with abnormally high pressure, this paper puts forward a new method for treating heavy mud by use of compound ion-type polymer. By using this method, a good result was obtained both in indoor experiment and initial practice at well-site. The method is available for reference.
