| 摘 要： | 在套管射孔压裂井中,存在影响井生产动态的裂缝伤害:瓶颈裂缝和压裂液滤失形成的滤失带伤害.运用分析方法研究了上述伤害对井产能的影响.分析结果表明两种类型的裂缝伤害都会降低压裂井产能,与滤失带伤害相比,瓶颈裂缝大幅度地降低了井产能,最大降幅达7倍.虽然压裂液滤失对井产能的影响没有瓶颈裂缝那么大,但也降低多一半.在实际施工中,应采用各种措施消除瓶颈裂缝和减小压裂液滤失.

| Abstract: | In the fracture well of the casing perforation, the fracture was damaged, that is the choked fracture and fluid leak - off damage. An analyzable method was introduced to study the effects of fracture damages on fractured well productivity. The results indicated both can greatly decrease productivity index while choked fracture had more side effects on well productivity. Some measurements must be taken to minish choked fracture and decrease fracture fluid leak off. |
