| 摘 要： | 以胜利油田砂岩油藏为例,分析了砂砾岩油藏具有储层物性差、岩性多样、连通性低、裂缝普遍发育、储层岩石以亲水为主的特点。实验研究表明,砂砾岩储层压裂时以脆性破坏为主,裂缝形态扩展复杂,压裂液滤失严重。通过射孔参数优化、压裂液优选、组合支撑剂评价,以及施工参数优化等,形成了砂砾岩储层压裂改造的关键技术。在Y104-1C井进行现场应用,增产效果显著,值得在类似储层的改造中推广。 |

| Abstract: | Taking of the sandstone reservoir in Shengli oilfield as examples,characteristics of poor physical properties,lithology variety,low connectivity,fissure growth and water wetting as glutinite reservoir are analyzed.Experimental studies indicate that brittle failure of formation is the main phenomena when operating rock hydraulic fracture in the glutinite reservoir,and fracture morphology is complicated and fracture fluid leak-off is serious.Through optimizing and valuating of perforating parameters,fracture ... |
| Keywords: | glutinite fracturing and reforming perforation optimization combined proppant field application |
