About regulation of rheological parameters and preparation of emulsions with oil - water content
Y.M. AliyevDuring various technological processes for the use of operation in oil wells it is necessary to prepare emulsions. There is a great importance to obtain emulsions with set rheological properties. In a special laboratory installation have been studied water and oil formation and showed that the main requirement is the quantity of the asphalt - resin compounds in oil content and dispersion of water with certain limit. Oil and water samples from Balakhany Oil OGDC 3951, 35081 numbered wells and commodity reservoirs were studied for ability of emulsions formation. It has been determined that 3951 numbered well exploiting KaS II horizon lower division of Productive Series (PS) forms quite sustainable emulsions with all water sample. Commodity reservoirs oil accumulated from different horizons also has an ability to form emulsions. 35081 numbered wells oil operating in PS upper division III horizon cant form emulsions with any source of water. Research works have shown that in the preparation of emulsions with necessary rheological parameters the quality of oil has of great importance and thus the main criterion should be the reduction of oil consumption to minimum. Also was determined that the sustainability of emulsions depends on its dispersion and rheological characteristics of the disperse medium. For the preparation and the use of emulsion in the field conditions was proposed special setup to regulate the parameters of the disperse phase with hydrodynamic method.
