钻井液回收率提升装置获专利

Core Viewpoint - The invention of a "squeezing-type drilling cuttings concentration and liquid separation device" by Shengli Oil Engineering Company aims to improve the efficiency of solid-liquid separation in drilling operations, enhancing the recovery rate of drilling fluid from cuttings [1] Group 1: Invention Details - The newly patented device is designed for solid-liquid separation of liquid-containing cuttings generated by drilling fluid solid phase control systems [1] - It addresses the high moisture content in separated cuttings from existing equipment like vibrating screens, centrifuges, and filter presses, which are often costly and prone to maintenance issues [1] - The device features a compression chamber, liquid collection chamber, compression drive mechanism, solid input/output mechanisms, and a liquid discharge mechanism, allowing for natural sedimentation, filtration, and squeezing concentration [1] Group 2: Benefits and Efficiency - The device significantly reduces the moisture content of cuttings, solving issues related to transporting solid phases during adverse weather conditions [1] - It is characterized by a simple structure, high reliability, and low manufacturing costs, utilizing mechanical physical processing methods for liquid recovery [1] - The recovered liquid phase is the drilling fluid, which can be reused on-site in real-time, greatly increasing the recovery rate of drilling fluid [1]
