GK-15型地质岩心钻探泥浆固控装置研究应用

固相控制装置在石油钻井中应用比较广泛,已实现系列化、标准化和专用化。地质岩心钻探在深度、口径和工艺等方面不同于石油钻井。因此,石油钻井固相控制装置不适合在地质岩心钻探施工中使用。GK-15型地质岩心钻探泥浆固相控制装置是在综合石油钻井固相控制装置特点的基础上,结合地质岩心钻探工艺的需求,把振动筛、清洁器和离心机通过管路联接,构成封闭的泥浆固相控制装置,实现泥浆的制备、循环、固相控制和储备。介绍了GK-15型泥浆固相控制装置结构、性能参数以及取得的使用效果。

Study and Application on GK-15 Mud Solid-phase Control Device for Geological Core Drilling

Solid-control device is widely applied in petroleum drilling and has been implemented in series, standardization and specialization. Geological core drilling is different from oil drilling in depth, diameter and process. The GK-15 mud solid-control device for geological core drilling is developed on the basis of the comprehensive characteristics of solid-control device for petroleum drilling and combined with the requirements of geological core drilling technology, the vibration sieve, cleaner and centrifuge are connected through a pipeline to form a closed mud solid control device to achieve of slurry preparation, circulation, solid control and reserve. The paper introduces the structure and parameters of GK-15 mud solid-control device for and sums up the application conclusion.
