浅谈低渗透油藏的增产技术改造

低渗油藏资源丰富,分布面广,开采难度大,要使低渗透油藏得到有效开发,必须对低渗透油藏的增产技术进行改造。水力压裂技术、爆炸压裂技术和复合技术是低渗透油藏增产技术改造的具体方法。它们具有独特的优势,在生产中发挥了不同的作用,但也存在着不足,对其进行改造时,在理论上要注意多学科的交叉运用,以油藏地质和油藏保护为出发点;在实践上将现有的多种技术结合起来联合作业,实现优势互补,降低作业成本。

Stimulation Technology Improvement for Low Permeability Reservoirs

Low permeability reservoirs, which have rich resources, large distribution areas but more difficulties in exploitation, must be improved in stimulation technology. The specific stimulation methods include hydraulic fracture, exploding fracture and compound fracture, which have peculiar advantages respectively and play different roles in production. However they have some shortcomings as well. While improving these methods, the author advocates both multidisciplinary application on the basis of reservoirs geology and reservoirs protection in theory and combining several current kinds of technology to fulfill mutual supplement and cost decrease in practice.
