摘要
基于对河南油田稠油油藏开发井存在的油井近井地带堵塞机理分析，研究论证了压裂充填工艺技术在稠油油藏解堵增渗的可行性，并结合油藏条件对压裂充填施工参数进行优化，现场应用表明：压裂充填工艺增产效果突出，具有改善油井渗流能力、提高原油产量的技术优势。
Based on the analysis on blocking mechanism in adjacent wells in heavy-oil reservoir development in Henan Oilfield,the feasibility of blockdown and permeability increment in heavy-oil reservoirs using the techniques of fracturing and filling was studied.In combination with reservoir condition,the fracturing and filling parameters were optimized.Field application result indicates that its effect is evident and it has the advantages of improving filtration ability and enhancing oil production rate.
