STATE, CHALLENGES AND PROSPECTS OF DEVELOPMENT OF THE METHOD FOR SIMULTANEOUS-SEPARATE OPERATION OF WELLS USING ECP UNITS IN THE MULTIHORIZON FIELDS OF WEST SIBERIA

Abstract

To create the operable equipment for simultaneous-separate operation of wells by electrical centrifugal pumping units (“SSO-ECP”) the experience gained by domestic and foreign specialists in this equipment designing, manufacturing and introduction was studied. It is offered to experimentally apply the assembly of SSO-ECP -A unit in wells being in operation for development of multihorizon fields with the purpose to increase these horizons oil recovery factor and current flow rates of wells. It is shown that for perspective development of SSO-ECP it is necessary to speed up the designing process and to arrange the commercial production of automated well systems of flow rate control and water encroachment of layers separated in the borehole, well chokes, and to prepare the industry «Methodical recommendations for designing the SSO technologies in multihorizon oil fields of Russia».
