用逐步稳态替换法确定低渗油藏合理井距
Determination of reasonable spacing in low permeability reservoirs by means of series of steady state analysis
摘要
Abstract
The reasonable spacing of low permeability reservoir was determined by means of series of steady state analysis based on the continuous model of non-linear flow proposed by Yang Qingli and the latest experimental data. And the impact of threshold pressure gradient and driving pressure difference on reasonable spacing was analyzed. The results show that the threshold pressure gradient strongly affects the reasonable spacing, the greater the threshold pressure gradient, the smaller the reasonable spacing is. When the threshold pressure gradient is small, the producer-injector spacing increases with driving pressure difference increasing. When the threshold pressure gradient is great, driving pressure difference has little impact on the reasonable spacing, and fracture treatments should be taken to develop low permeability reservoirs economically. Compared with steady state method, the results obtained by this method agree well with the practice of low permeability reservoir development, which can guide the development of low permeability oilfield.关键词
