    摘要:

    压裂是低渗透油藏的主要增产措施,但常规压裂存在有效缝长短、易受到压裂液的污染等问题,为增加压裂裂缝有效缝长,实现压裂裂缝的无限导流能力,提高压裂成功率及效果,从工艺适用条件分析、非连续支撑剂铺置导流能力实验和保持高速通道的方法3个方面对高速通道压裂工艺进行了研究。优选纤维长度为10 mm,直径为15 μm,质量浓度为10 kg/m3,最佳方式为纤维支撑剂一起加入,从而形成了自主的高速通道压裂工艺。现场实施2口井,成功率为100%,截止到2014年12月底,累积增产原油量为3 700 t,与同区块采用常规压裂工艺的油井相比增产15%。与常规压裂相比,高速通道压裂工艺的适应性强,施工难度低,有较好的增油效果,适用于低渗透油藏的开发,推广前景广阔。

    Abstract:

    Fracturing is the major stimulation in the low permeability reservoirs,but the conventional fracturing has the problems of short effective fracture and being susceptible to fracturing fluid pollution. In order to increase the effective fracture length,to realize infinite conductivity of the fractures and to improve the success rate and effect,Hiway technology was researched from the aspects of applicable conditions,flow capability experiment of non-continuous proppant laying and method of maintaining the Hiway. The optimized fiber is:length is 10 mm,diameter is 15 μm,mass concentration is 10 kg/m3. The fiber and proppant should be injected together. Independent Hiway technology may be formed. It was applied to two wells in the oilfield with a success rate of 100%. By the end of December 2014,the cumulative incremental oil production is 3 700 t,increased by 15% compared with the oil wells in the same block by conventional fracturing. Compared with the conventional fracturing,Hiway technology has strong adaptability,low construction difficulty and good stimulation effect. It is suitable for the low permeability reservoirs with broad prospects.
