Study on the influencing factors of productivity under pressure drive development in low permeability reservoir

The productivity of low-permeability reservoirs is affected by multiple factors. After the development water injection pressure drive, it will also be factors such as construction, resulting in large differences different oil wells. According to reservoir engineering knowledge, affecting drive are preliminarily determined. conceptual model low permeability established numerical simulation method. Combined with orthogonal design, main control include production well spacing, volume measures, content before porosity, and quantitative analysis Through correct evaluation these factors, provides guiding significance for prediction optimization scheme.
