摘　　要：常规酸压与加砂压裂均有技术优势,也有技术局限性;酸压携砂作业将两者的技术优势集成在一起,适应了复杂油气藏储集层改造地质需求。JN、CYY和CZY三种地面交联酸的性能较佳,宜于酸压造缝和携砂充填作业。针对泥质粉砂岩、火山岩和白云岩油气藏裂缝—孔隙型储集层地质特征,采用特色泵注技术作业,施工成功率很高,成效显著。施工范例解析有助于深化认识,促技术成熟。The conventional acid fracturing and sand fracturing have technical advantages,but there are technical limitations.Acid fracturing carrying sand operation integrate the technological advantages both conventional acid fracturing and sand fracturing,it can meet the demand of geological transformation of complex reservoir.The performances of JN,CYY and CZY crosslinked acid are better,they are suited for acid fracturing making fractures and carrying sand filling operation.According to the geologic characteristics of fracture porosity reservoir of muddy siltstone,volcanic rocks and dolomite,the success ratio of characteristic pump injection technology operations is very high.Sample analysis of operation will be helpful to deepen understanding,promote maturity of the technology.
