摘　　要：在已建立的裂缝高度延伸机理模型的基础上,从地层应力、岩石物性和施工参数等方面分析了酸压裂缝高度延伸的影响因素,并对裂缝高度延伸控制给出了诊断方法。结合酸压工艺特点,从降低地层破裂压力、人工隔层控缝高、降滤失控缝高以及从酸压液体系、完井方案的优化、施工压力监控等各个方面讨论了控缝高酸压技术。This study bases on the established fracture height extension mechanism model,analyzes the influence factor on fracture height extension from the aspects of in-situ stress,rock physical property and operation parameters,and gives the diagnosis method for fracture height control.Combining with acid-fracturing process characteristics,the fracture height control technology is discussed from aspects of reducing stratum breakdown pressure,controlling fracture height by artificial insulation and fluid loss control,as well as acid fluid system, well completion plan optimization,and operation pressure monitoring.
