Coalescence type multiphase cyclone separator

Abstract

The invention discloses a coalescence type multiphase cyclone separator which is in vertical installation. The coalescence type multiphase cyclone separator comprises an oil-gas separation cavity, a cyclone separating cavity, a solid-liquid separation cavity and a solid phase sedimentation tank. The oil-gas separation cavity, the cyclone separating cavity, the solid-liquid separation cavity and the solid phase sedimentation tank are sequentially welded. The oil-gas separation cavity is provided with a natural gas outlet and oil outlets. The natural gas outlet is arranged at the front end of the oil-gas separation cavity, the number of the oil outlets is two, the cyclone separating cavity is provided with produced liquid inlets, and the number of the produced liquid inlets is two. The solid-liquid separation cavity is provided with two water outlets, each part of mixed liquid is separated through centrifugation, separated oil and gas flow into the oil-gas separation cavity and then are discharged through the natural gas outlet and the oil outlets, separated solid and water enter the solid-liquid separation cavity, water obtained after solid phase and water phase separation is discharged timely out of the water outlets, and the solid phase is stored in the solid phase sedimentation tank to be discharged in a timed mode. Various used processes are greatly reduced, equipment is simplified, the efficiency is improved, energy is saved, and the cost is reduced.

Description

technical field [0001] The invention relates to the treatment of oil well production fluid in the field of oil fields, in particular to a coalescence multiphase cyclone separator. Background technique [0002] The multi-phase cyclone separator is used after the oil well production fluid is pumped out and before the oil-water separation equipment. Since the oilfield production fluid treatment process at this stage is: gas-liquid separation, liquid-solid separation, liquid-liquid separation, crude oil treatment, desalination, water treatment , water injection, crude oil stabilization and other processes, the existing process structure is cumbersome and complex, requiring many types of equipment and power sources, each process requires special connection requirements, and some processes require heating and other conditions for liquid temperature. Therefore, it is necessary According to practical experience and on-site commissioning of equipment, design a separation equipment th...
