Energy-saving solid control system

Abstract

The invention discloses an energy-saving solid control system. The system is that the original four-stage solid control process is simplified into two-stage solid control process, which is the optimal working mode after carefully analyzing the working state of a plurality of field drilling well site solid control systems. According to the system, the quantity of vibrating screens is increased; a sand remover and a mud remover are integrated; the sand remover and the mud remover are generally avoided using in the solid control process; in case of a cement stratum, the sand remover and the mud remover are integrated and temporarily used in the solid control process; the solid control process is scientifically changed, so that lots of energy can be saved, the working efficiency can be increased, and the solid control cost can be greatly decreased.

Description

technical field [0001] The invention relates to an energy-saving solid control process, which belongs to the field of solid control in drilling rig well sites. [0002] Background technique [0003] Drilling fluid solid control is the core part of the drilling fluid circulation system. According to the principle of solid control classification, the drilling fluid treatment and solid control equipment placement procedures are vibrating screen + desander, desilter + centrifuge + large and medium displacement The centrifuge belongs to the four-stage solid control. The vibrating screen is the first-level leading equipment of the solids control system, and it is the only one with full flow treatment, so the reliability of the vibrating screen is very important. The quality of its working performance directly affects the working effect of the subsequent stages of solids control equipment and the mud The quality of the system. The good working performance of the vibrating scree...

AI Technical Summary

Problems solved by technology

1) Vibrating screens are better used, and the ratio of high-mesh screens that can be used is relatively high, but this is not the whole process, especially when the pulping is very serious in the early stage of 1-open and 2-open, most of them can only use 40-80 mesh

2) The effect of the desander and desilter is very poor. After the vibrating screen uses a 100-mesh screen, the desander and desilter hardly produce materials, especially when the pulping in the early stage of 1K and 2K is serious, normal low work rate

3) The centrifuge works well in the non-weighted mud system, but it cannot be used in the weighted mud system, because the weighted barite and iron ore powder are separated and discharged in large quantities, which destroys the weighted mud system
