真诚地向各位大侠求助一下几本钻井液英文书籍，原已花前购买
1.“Composition and properties of Drilling and Completion Fluids” G.R.Gray”, Fifth
Edition. Gulf Publishing Company, 1997
2.“Principles of DRILLING FLUID CONTROL”, Edited by A Subcommittee of the API
Southern District Study Committee on Drilling Fluids, Published by PETROLEUM
EXTENSION SERVICE,
3、“IDF TECHNICAL MANUAL”,The Advanced Technology of International Drilling Fluids.
急需! 不知道求助书籍是否违反版规，如果是，还请版主手下留情，工作继续.国内的书店和网点都没找到。
先行谢过了
