Purpose
Preliminary water discharge units (UPSV) are intended for preliminary oil dehydration in production headers near the most watered well clusters, on lower sections of the route where free water accumulates, in locations of existing oil pumping stations, in well clusters.
UPSV are designed to use in moderate and moderately cold climate with air temperature:
— from 40 °C to –45 °C for moderate climate
— from 40 °C to –60 °C for cold climate
Preliminary water discharge unit (UPSV) designed by "ROG-Engineering" LLC includes all the main intensifying methods of separation process to achieve improved performance compared to traditional technologies. This increase of 1,5–2 times is due to:
— optimized use of chemical reagents based on previous studies;
— pipe demulsification and formation of favorable structural forms of liquid gas mixture for high gas-containing and sand jet wells at inlet of UPSV;
— combining of simultaneous gas and water separation processes;
— use of natural heat content of products (without heating);
— use of hydrodynamic effects for intensification of internal devices of separators and settling tanks.
