摘要
某海上钻井项目需要一种海水钻井液用环空流变性改善剂 ,要求在钙质膨润土泥浆中加入 1%的改善剂 ,泥浆胶体稳定性好 ,表观粘度≥ 3 0mPa·s ,动切力≥ 10Pa ,滤失量≤ 10mL ,且要价格经济合理 ,可接受。本文介绍了该改善剂的室内研究过程 ,最后给出了满足要求的配方 ,该配方原料来源广泛 ,价格经济 。
One offshore drilling project needs a annulus rheologic properties improving agent used in seawater drilling fluid. When added 1% this agent into Ca-bentonite mud this mud must meet the requirement: good stability of mud colloid, apparent viscosity≥30mPa .s, yield stress≥10Pa, fluid loss≤10ml. And the price of this agent should be economical, reasonable and acceptable. This paper introduces the process of laboratory study of this agent, and at last gives the formula of this agent. The source of raw materials for this formula are extensive, inexpensive and they have a good capability.
