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