从压裂裂缝参数优化、水平缝脱砂技术、压裂液、高砂比管柱等方面全面论述了短宽缝压裂工艺技术的研究及现场应用情况。裂缝参数理论给出了不同井网和地层条件下最佳裂缝穿透比和导流能力，为短宽缝压裂工艺提供了定量的理论依据；高砂比管柱以其独特的结构及性能实现了高砂比、一趟管柱可压多层、可反洗、能分体等工艺要求，为短宽缝工艺实施提供了必要的技术保证。现场试验证明，短宽缝压裂配套技术，可将裂缝半径控制在19～25m之间，裂缝支撑缝宽能够达到相同施工规模、常规压裂的2．5倍。该工艺技术成为大庆油田三次加密井压裂改造的重要手段之一。
From the aspects of fracturing parameters optimization, horizontal seam sand removal technology, fracturing fluid, sand compaction and so on, the research on short and wide-gap fracturing technology and field application are comprehensively discussed. The theory of fracture parameters gives the best fracture penetration ratio and diversion ability under different well patterns and strata conditions, which provides a quantitative theoretical basis for the short and wide gash fracturing process. The high-sand ratio of the pipe string is realized by its unique structure and performance The high sand ratio, a trip to the column pressure multi-layer, backwash, can split the process requirements for the implementation of short and wide slit technology provides the necessary technical assurance. Field tests show that the short width and width fracturing supporting technology can control the fracture radius between 19 and 25m, and the fracture support width can reach 2.5 times of the same construction scale and conventional fracturing. The process technology has become Daqing Oilfield three infill wells one of the important means of fracturing transformation.
