| 摘 要： | 利用油藏渗流理论,基于裂缝为有限导流能力,建立了水力压裂油井产能计算模型及其求解方法,并编制软件计算分析了低渗透油藏水力裂缝参数对油井产能的影响。结果表明,当裂缝半缝长一定时,裂缝的导流能力对油井IPR曲线的影响较小;而当裂缝的导流能力一定时,裂缝半缝长对油井IPR曲线的影响明显,提高裂缝半缝长能显著增加油井的产量;对于一定的裂缝半缝长,存在最佳的裂缝导流能力。

| Abstract: | Computational models of productivities of hydraulically fractured oil wells are built by using reservoir percolation theory and based on the finite conductivity of fractures. Software is programmed to analyze the influences of hydraulic fracturing parameters on oil well productivity. When the half- length of a fracture is given, the influences of fracture conductivity on IPR curves of oil wells are relatively small. While when fracture conductivity is given, the half- length of the fracture has remarkable influences on IPR curves of oil wells. Production of oil wells can increase significantly when the half - lengths of fractures increase. An optimum fracture conductivity exists for a given fracture half - length. |
