摘要
针对中原油田文72和文95等断块的地质特点及定向井的工程要求,设计了以KH931为主剂的新型防塌钻井液体系。室内试验和现场应用表明,该体系具有较强的抑制性、抗盐膏能力和良好的润滑性,很好地解决了这些区块的泥页岩水化膨胀导致缩径、盐膏层污染严重等问题,为这些区块的定向井钻井探索出了一条成功之路。
Based on the geological property of the Wen 72 and Wen 95 blocks in Zhongyuan Oilfield and the engineering requirements of the directional wells, a new drilling fluid system which uses KH-935 as principal component is developed. Lab tests and field applications show that this system has powerful inhibitivity, salt-resisting capability and good lubricity. It successfully solved the problems in those blocks, such as hole undergauge owning to hydration swell of shale and the pollution of the salt pay zone. So a success way to drill directional well in those blocks is developed.
