Analysis of well and layer selection method for fracturing displacement in thin-and-poor layers in the transition zone of A Oilfield

This paper mainly provides the well and layer selection method of fracturing displacement. It solves problem insufficient formation energy lack forming effective communication between oil water wells, resulting in poor injection capacity thin-and-poor layers, production capacity, deficit seepage capacity. The research includes following two parts. (1) Target wells were optimized by selecting those with relatively perfect relationship, oil-water connectivity long-term deficit. should be porosity, low air permeability some development potential. They are required to meet construction requirements large capability fluid into wells. (2) layers based on injection-production relationship target well, reservoir thickness, interlayer liquid production, intensity, pressure, situation other parameters. Then, sedimentary unit high potential is selected as layer. improves effect stimulation layers.
