水性钻井泥（WBM）

What Does Water-Based Drilling Mud (WBM) Mean?

Water-based drilling mud (WBM), otherwise known as water-based drilling fluid, has freshwater or saltwater as its major mixing medium, unlike oil-based drilling fluid in which oil is the major mixing medium. Additives such as polymers are added to change the density, viscosity, control circulation loss, and other parameters as required for the project.

WBMS便宜，环保。钻井液是挖掘管道安装项目的重要组成部分，并在钻孔路径中定制到普遍的地面条件，在抵达添加剂的正确组合之前，需要广泛的岩土和土壤调查。

The primary constituent of drilling fluid is water, and additives constitute only about 3-4%. The quality of water will also affect the final drilling mud because water has to be sourced from creeks, rivers or the city. Additives will be more effective when the pH of the water on the pH scale is between 8.5 and 9.5; calcium content should be below 100 parts per million (ppm).

钻井液的主要组成部分是膨润土，它是粘土床中的矿物质。当与水相结合时，它形成类似蛋糕的纹理，有助于密封钻孔壁，防止钻井液通过钻孔壁中的裂缝逸出，导致Frac-out。

浆料提供的支撑件也使钻孔塌陷。
