摘　　要：塔河油田碳酸盐岩油藏缝洞储集体距离井眼超过120m以上、井层埋深超过6000m以上的超深井储层。针对目前的酸压工艺不能实现有效沟通这类远井缝洞发育带的问题,提出了超深裸眼碳酸盐岩储层水力加砂压裂技术,具体就是综合选井选层、地应力及岩石力学参数模型、压裂液体系筛选、工艺设计研究、裂缝监测与评价等技术的研究及应用,既能形成较长的有效裂缝长度,又能确保裂缝高导流能力,从而达到进一步提高沟通更远处的有效储层的机率,提高储层改造效果目的。The super-deep well reservoir bed in the carbonate reservoir is above 120m deep,and the buried depth of the stratum surpasses 6000m.In order to deal with the problem that the current acid-fracturing craft technology can not effectively communicate with the developed band of fracture-vuggy,we put forward the hydraulic sand fracturing technology,which based on the research and application of an overall consideration of formation evaluation well choosing,crustal stress and rock mechanics parameter model,fracturing fluid system selection,and the study on technology design,monitoring evaluation of fissures various factors.It could form longer cracks,ensure higher conductivity,and reach the purpose of improving opportunity on communicating the further available reservoirs.
