    摘要
  • 摘要: 针对孟加拉亚热带雨林气候常年高温情况，提出了孟加拉定向钻海水泥浆体系面临的问题和性能要求。针对孟加拉定向钻海水泥浆体系（海水+6%抗盐膨润土A1/B1/E1），优选研制了复合杀菌剂HCA101。该杀菌剂与体系配伍性好，添加0.1%杀菌剂的定向钻海水泥浆体系高速搅拌不起泡，在35℃下发酵时间大于10 d，满足现场泥浆体系发酵控制要求。该杀菌剂首次在孟加拉单点系泊项目中应用，取得了良好的施工效果，连续施工20 d后泥浆性能仍很稳定，未出现高温发酵现象，值得在国内外海上和类似孟加拉气候的定向钻海水泥浆体系中推广应用。

     

    Abstract: Oil well drilling in the subtropic rain forest climate in Bangladesh is facing high temperature environment through the whole year. To prevent the negative effects of high temperature on the performance of drilling fluid, a compound bactericide HCA101 was selected to treat the seawater drilling fluid (seawater + 6% salt clay A1/B1/E1) for directional drilling. HCA101 is compatible very well with the drilling fluid; treatment of the drilling fluid with 0.5% HCA101 does not cause the mud to foam when agitating at high speeds. Time for the HCA101 treated mud to ferment is longer than 10 d, satisfying the needs of fermentation control in field application. HCA101 was first used in March of 2019 in a single-point mooring project in Bangladesh with good operational results; the mud properties were stable after successively 20 d of operation, no fermentation at high temperatures was found. This bactericide is worth spreading in operation with seawater drilling fluids in an environment that is similar to that in Bangladesh.
