Petroleum exploration and develop are facing more and more strict environment requirements all over the world, especially in offshore area. A fresh water base mud and a sea water base mud have been recently developed, with the negative-charged poly alcohols and positive-charged coating agents being the main additives. The two muds have better shale inhibitive capacity. The main additives in these two muds are all chemically modified naturally products, which are low-toxic and are able to degrade automatically. This paper discusses the evaluation of the performance of the main additives and the mud properties. The application of the muds in 21 wells, such as well Zhanghai-4, Zhuanghai-5 and Zhuanghai-2 × 1, to name three, is also introduced. Laboratory study and field application showed that the two drilling muds pur-formed very well in mud lubrication, shale inhibition, temperature stability, contaminant tolerance, reservoir protection and are environmentally friendly. The rates of overcut of the wells drilled with the drilling muds are less than 6% and the production rate of these wells are high (averaged 36 t/d). Electric loggings are very successful. Wells drilled with the drilling muds found higher ROPs. The drilling muds have better solids carrying capacity and lower friction coefficient (less than 0. 08). The low toxic negative-charged poly alcohol muds not only met the requirements in offshore use, they can also be used in shallow and medium-deep wells for borehole stability, lubrication and fast-drilling purposes.

勘探开发对环境保护的要求越来越严格,滩海等环境敏感区域更是如此。以提高钻井液抑制性为核心,研究出了正电聚醇和正电护壁剂2种产品,并形成了淡水和海水2套正电聚醇体系。该体系的主要处理剂均由天然矿物经化学改性而成,能够自动降解,具有低毒特性。评价了环保型正电聚醇钻井液主处理剂的作用及体系性能,介绍了其在张海4、庄海5及庄海2x1等不同类型的12口井的应用效果。室内试验和现场应用结果表明,该体系具有良好的润滑防塌、抑制、抗温、抗污染、油气层保护和环保性能;应用井井径扩大率小(小于6%),产油量高(平均达36t/d),电测1次成功;该体系有利于提高机械钻速,携岩能力强,摩阻系数小于0.08。指出,低毒正电聚醇体系能满足海洋井的环境保护需要,也可满足浅井和中深井井壁稳定、润滑和快速钻进的要求。
