With the development of Bohai oil and gas fields entering the middle and late stages, the pressure and efficiency reducing have become increasingly prominent. For the technical problems of reservoir protection in the current completion operation, high-efficiency adjustment of interlayer separation of fine oil layer, an offshore oilfield frac-pack sand control for single multiple subdividing zones system is proposed. According to offshore oilfield with 244.5 mm production casing of single multi-layer packing sand control completion, the domestic and foreign status of similar technology research has been investigated, analysis of their technical characteristics and scope have been studied, the frac-pack sand control for single multiple subdividing zones pipe and the necessary wells tools, simulation analysis and parameter optimization has been proposed, the applicable range of the technical parameters, the comprehensive comparison of various advanced technology, advantages and risks have been verified, the specific and reliable data support for the follow-up design and product refinement of frac-pack sand control for single multiple subdividing zones have been provided.
