摘要:

钻井液振动筛是石油钻井固控系统的关键设备,用于钻井液中有害固相颗粒的清除和钻井液的回收,对节约资源和保护环境具有重要意义。随着石油工业的发展,要求钻井液振动筛提高处理量,因此提出了一种新型负压钻井液振动筛。负压钻井液振动筛与传统钻井液振动筛的区别在于前者利用振动筛分和真空过滤的联合作用来提高振动筛的处理量。为了更深入了解负压振动筛的性能,基于传统钻井液振动筛上的单颗粒模型,用力学观点详细讨论了固相颗粒在负压振动筛上的运移规律,比较了不同参数下固相颗粒在2种振动筛上的运动情况,并分析了负压系统的应用对振动筛结构参数的影响。结果表明负压振动筛上固相颗粒的运移速度小于传统振动筛上固相颗粒的运移速度,这更有利于固液分离;负压系统的应用对振动筛结构参数的影响较小,可直接将传统振动筛改造为负压振动筛。研究结果为负压振动筛的设计和现场使用提供了理论依据。

Abstract:

Drilling fluid vibrating screen is the key equipment of solid phase control system for oil drilling and it is used to remove the harmful solid particles in the drilling fluid and recover the drilling fluid,which is of great significance to conserve resources and protect the environment. With the development of petroleum industry, higher requirements are put forward for vibrating screen. Therefore, a new type of negative pressure drilling fluid vibrating screen was proposed. The difference between the negative pressure drilling fluid vibrating screen and the traditional drilling fluid vibrating screen was that the former combined vibration screening and vacuum filtration to improve the processing capacity. In order to understand the performance of negative pressure vibrating screen in detail, based on the single particle model of the traditional vibrating screen, the conveyance law of the solid particle on the negative pressure vibrating screen was discussed by the mechanical view, and the movements of solid particle on the two kinds of vibrating screens under different parameters were compared. Besides, the effect of negative pressure system on structure parameters of vibrating screen was analyzed. The results indicated that the conveyance speed of solid particle on the negative pressure vibrating screens was slower than that on the traditional vibrating screens,which was more conducive to the separation of the liquid and solid. In addition,the application of the negative pressure system had little influence on the structural parameters of the vibrating screen, so the conventional vibrating screen could be directly converted into a negative pressure vibrating screen. The research results provide a theoretical basis for the design and field application of the negative pressure vibrating screen.
