Study On The Crude Oil Two Section Dehydration For Jin 16 Block Chemical Flooding

Jin 16 block of Liaohe oilfield waterflood development has been more than 20 years, most well integrated water rate has exceeded 90%, recovery more than 40%, has entered the stage ofhigh mining. Fault block production decline and water cut increase has not slowed by the routine method, must adopt new methods, new techniques to increase based on flood development of recoverable reserves, enhanced oil recovery, started in the context of chemical flooding oil production is three times need to be sustained and stable development of Liaohe oilfield.Huan combined chemical flooding oil dehydration station is Jin 16 block of chemical flooding oil and gas gathering and treatment engineering in the most important part, Huan three joint stationunder the Jinzhou oil production plant, has been running for thirty years, the station has been built for chemical flooding process can not meet the crude oil dehydration processingrequirements, the need for process modification necessary.Through indoor dewatering test, collecting research data, put forward new and centralized processing station scheme Huan triple transformation scheme, design, plan for process ofcomparison and optimization, to determine the Huan three joint station reconstruction scheme,and puts forward the Huan combined the main problems and reform. Eventually adopts theprocess scheme of pressure settlement, electrochemical dehydration of crude oil dehydration processing, to ensure the efficient, safe, reliable, energy saving.According to the design scheme, parameter determination, process calculation, to further determine the renovation measures, fully utilize the facilities, equipment like triple station,optimization of process flow, preferably a new equipment, ensure that after the transformationprocess of energy saving, high efficiency, investment at least, the highest economic benefit;meanwhile carries on the transformation to the safety, Huan combined station environment, fire protection and energy-saving measures, make the joint station can be safe, stable operation.Through the research for the Jin 16 block of chemical flooding of crude oil dehydration processprovides the guiding ideology, which provides guarantee for normal production operation forunion station, union station renovation Huan specific implementation provides a foundation, has the vital significance.
