High Contains Water The Later Period To Pick The Fluid Demulsifiers And To Add The Medicine Craft Engineering Research

The Daqing Oil Field majority of extractions sub-area already entered high contains water thedevelopment later period, the oil well picks the fluid synthesis moisture content to surpass 85ï¼…, and thepartial oil wells pick the fluid synthesis moisture content to achieve above 90ï¼…. Along with picks thefluid moisture content the growth, picked the fluid the emulsion type also to have the remarkablechange, oil contains water type (W/O) transformed by the oil-field development initial period into awater package of oil type (O/W) and a water package of oil contains water type (W/O/W) the multipleemulsion, Various oil fields use demulsifiers formula, the demulsifiers appraisal method as well as thedemulsifiers action mechanism research mainly is aims at the W/O crude oil emulsion to propose, inview of the O/W crude oil emulsion demulsifiers action mechanism, the emulsion breaker formuladevelopment and in the demulsifiers room appraises the work which the method aspect develops very tobe also few. Therefore high contains water later period W/O/W to pick the fluid demulsifiers actionmechanism research, the demulsifiers formula development, in the demulsifiers room appraises themethod the research to have the count for much significance.The present paper tests through the room in, high contained water in view of the Daqing Oil Fieldthe later period to pick the fluid the water-oil separation characteristic, the application weak electricitycharacteristic analyzer has determined the lubricant film parameter, between changed the speed throughthe lubricant film electric capacity to reflect the lubricant film as necessary the thin speed; To affects thelubricant film thin speed the factor to conduct the analysis research, obtains the emulsion breaker theaction mechanism; Established high contained water the later period to pick in the fluid demulsifiersroom to appraise the method; Proposed suits the Daqing Oil Field high to contain water the later periodto pick the fluid emulsion breaker to add the medicine new draft.Through the field test, to the crude oil dehydration temperature, the pressure, the Canadian dose andadds the medicine craft to carry on the industry experiment, realized the water drive emulsion breaker toadd the dose to reduce 30ï¼…, the polymer drives the emulsion breaker to add the dose to reduce 15ï¼…, theunion station crude oil dehydration system movement is steady, solves the oil field crude oil dehydrationto live the mid-production technical difficult problem.
