低渗透油藏考虑压裂的注采井间压力分布研究

Study of Pressure Distribution under the Consideration of Fracturing between Injection and Production Well in Low Permeability Reservoirs

低渗特低渗油藏都要进行压裂才具有经济效益。提出水井爆燃压裂、采油井水力压裂情况下的注采井间压力分布的求解思路,运用达西径向渗流模型、一维条带状渗流模型和拟线性渗流模型相结合的方法,更准确地求解注采压力分布,符合现场实际应用。

The vast majority to low permeability extra-low permeability reservoirs only to be fractured have industrial output.This paper puts forward the solving thinking and method of pressure distribution under the consideration of explosive fracture of injection well and hydraulic fracture of production well,combining the Darcy radial flow model,single dimensional seepage flow model and pseudo-linear flow model.It has a good guide in further studies on the distribution of pressure and selecting the best low permeability pattern well spacing.
