一种新颖的仿生钻井液模仿模糊bacteriaAAA’本文介绍了细胞结构,它被命名为模糊球钻井液。AAA“特殊结构的一个核心,两层,三个membranesAAA”使模糊球仿生钻井液自动封堵能力,能够抵抗高压。模糊球仿生钻井液的组成可以调整根据不同的形成条件。模糊球仿生钻井液的主要成分是植物胶和纤维素,所以它是无毒的,对环境安全。模糊球仿生钻井液已成功应用在中国20多个井。本文提出了三种方法回收了模糊球仿生钻井液,1)分离的絮凝和生产低密度水泥浆;2)分离破胶和直接排放;3)直接和生产固体水泥固化。实验室实验研究每种方法的可行性。结果表明:1)产生的水泥浆絮凝分离液体能满足的需求shallowcementing井; 2) the separating liquid by gel-breaking satisfies the secondary standard of “GB8978-96 National Sewage Discharge Standard”; 3) the strength of solid cement produced by curing the dumped fuzzy ball bionic drilling fluid is high enough to be used for further well stimulation, and the leach liquid satisfies the secondary standard of “GB8978-96 National Sewage Discharge Standard”. All the three recycling methods can be adopted according to different working conditions. The research results improved the technical specification of the fuzzy ball bionic drilling fluid and proved a train of thought to recycling the dumped drilling fluid.
