High-Efficiency Pre-Treatment Core Tube for Produced Water in the Main Cavity Coupled with Secondary Cavities and Its Application in the Bohai Heavy Oilfield

Improving the produced fluid yield is an effective measure for realizing crude oil production capacity of offshore platforms. However, platforms employed in production, using narrow space platform to expand water treatment system a significant problem. In this study, highly efficient pre-treatment core tube was coupled with main cavity and secondary cavities (MCSCs) based on vane-type tubular separator cub-mother cyclone. The optimal inlet Reynolds number processing were determined according structure size MCSC, MCSC applied achieve heavy oilfield Bohai Sea. comprehensive evaluation indicators FA FV better than those used by current technology. When influent content fluctuated around 2000 mg/L (average 1772.81 mg/L), effluent stable below 200 106.44 separation efficiency nearly 94%. Compared corrugated plate interceptor platform, floor reduced more 60% increased up 65%.
