Design and Optimization of High-Viscosity and High-Density Drilling Fluid Separation System

Abstract:

For degassion of high-viscosity and high-density drilling fluid used in ultra-high pressure oil and gas zones, a two-stage vertical separation system was established. In this system, gravity separator was used as the first separator and the second separator was centrifugal separator. Using orthogonal experiment method, we simulated flow field in this system by CFD software and analyzed the effect of operate variable and structural variable on system degassion efficiency. In accordance with the characteristics of flow fields, the performance optimization scheme was presented.
