摘要:

页岩气藏人工裂缝起裂、裂缝延伸机理与常规储层有很大差异，且页岩储层天然裂缝和层理发育，体积

压裂改造导致加砂压裂异常，影响增产改造效果。针对威远页岩气藏储层特性，统计分析了威远龙马溪组42井次754层段的压裂施工，其中73层段出现不同程度的加砂

异常，从而归纳出导致加砂压裂异常的主控因素，包括气藏埋藏、天然裂缝发育情况和页岩页理层理结构、矿物组分等，形成高密集度加砂压裂、混合压裂、连续加砂

综合压裂和复合暂堵转向压裂等4种针对性的工艺技术。采取配套适应储层特点的工艺技术，可提高龙马溪组加砂压裂改造的成功率，为页岩压裂设计优化和现场施工

提供技术支持。

Abstract:

The mechanism of the artificial fracture initiation and propagation in

shale gas reservoir are greatly different from that of conventional reservoir. The natural fracture and bedding in shale gas reservoir usually

result in abnormal sand fracturing operation, which greatly influences the reservoir stimulation effect. In view of the reservoir properties of

Weiyuan shale gas reservoir, 754interval fracturing operations in 42 welltimes were statistically analyzed. There are 73interval sanding

anomalies in different levels. The maincontrolling factors leading to abnormal sand fracturing were summarized, including gas reservoir burial

depth, natural fracture development level, shale lamellation and bedding structures, mineral composition, etc. Four specific fracturing

technologies were developed, including highdensity sand fracturing, mixed fracturing, continuous sand fracturing and composite temporary

plugging fracturing. These technologies can improve the success rate of sand fracturing stimulation and could also provide certain technical

reference for the shale gas reservoir fracturing design optimization and field operation.
