| 摘 要： | 基于水力裂缝层内爆燃压裂技术提高低渗透油田采收率和油井产量的基本设想,利用油藏渗流理论和节点系统分析方法,建立了水力裂缝层内爆燃压裂油井产能计算模型,并分析了水力裂缝和爆燃裂缝参数对油井产能的影响。研究结果表明,在低渗透油藏中,增加水力裂缝的长度比增加水力裂缝的导流能力对油井增产更有利;爆燃裂缝的存在可在水力裂缝增加油井产量的基础上进一步增产,相对于水力压裂油井,爆燃压裂油井增产倍数可达1.55。由此说明,利用水力裂缝层内爆燃压裂技术来提高低渗透油田油井产量是可行的。

| Abstract: | Based on the basic idea of the stimulation with exploding in the hydraulic fracture front in low permeability reservoirs,a productivity calculation model was built using the theory of fluid flow in porous media and the nodal system analysis method.The effects of hydraulic fracture parameters and exploding fracture parameters on well productivity were analyzed.The results show that the well productivity is improved by increasing the length of hydraulic fracture more than that of increasing the hydraulic fracture conductivity in low permeability reservoirs.The hydraulic fracture well productivity can be enhanced by the exploding fracture and the stimulation ratio is up to 1.55.It proves that the technique of the stimulation with exploding in fracture front is feasible. |
