摘要
石油和地质钻井的钻井液一直采用阴离子型泥浆体系。阳离子泥浆休系是80年代出现的一种新型泥浆体系,它能更有效地解决因地层粘土水化膨胀及分散带来的一系列问题。阳离子泥浆体系采用田菁胶为增粘提切剂,最终实现钻井液和完井液的统一。
The drilling fluid used in petroleum and geology exploration was monopolized by anion-type mud system. In this paper, a new kind of mud system, the cation-type mud system developed in 1980's is introduced, which is more effective in solving problems caused by hydration, swelling and dispersion of stratum clay. Sesbania gum is used in this mud system as viscosity enhancer and carrying agent to achieve the goal of making a general mud for both drilling and well completion.
