| 摘 要： | 海洋深水钻井过程中容易遇到气体水合物堵塞井筒、环空、防喷器等钻井事故.用THF/ SSW测试法对部分钻井液组分做了评价试验,包括粘土、NaCl、MgCl2、CaCl2、XY-27、FCLS、CMC、PSC、PEG等.结果表明,钻井液无机组分中,粘土对气体水合物的形成起促进作用,而NaCl、MgCl2、CaCl2等无机盐则起抑制作用;大部分有机处理剂对气体水合物的形成起抑制作用.在了解了各组分对气体水合物形成的影响后,可以调节组分的用量,以达到抑制气体水合物形成的最佳状态.

| Abstract: | Accidents caused by gas-hydrate formation are easily encountered during deepwater offshore drilling. In this paper, drilling fluid ingredients and additives including bentonite, NaCl, MgCl2, CaCl2, XY-27, FLCS, CMC, PSC and PEG were evaluated using THF/SSW method. Testing results indicated that, 1) Among inorganic drilling fluid components, bentonite is a promoter in gas-hydrate formation, while NaCl, MgCl2 and CaCl2 are inhibitor; 2) Most organic additives exhibit suppression in gas-hydrate formation. Based on impacts of drilling-fluid ingredients and additives, a maximum hydrate suppression state can be achieved by conditioning additions of some additives. |
