连续油管酸化钻孔技术在碳酸盐储层改造中的应用
|
摘要
连续油管酸化钻孔技术作为新型、有效的储层改造技术已经成功应用于国外碳酸盐储层改造,并取得了良好的效果,国内目前还没有相关的作业应用。本文首先介绍了连续油管酸化钻孔技术工艺方案、井下工具、增产机理、技术特点、作业程序,连续油管设备选择等关键技术,然后以国外具体的现场应用情况为基础对连续油管酸化钻孔技术的可行性和存在的问题进行了分析总结。
Coiled tubing acid tunneling technology as a new effective stimulation approach has been applied on overseas oil and gas field to enhance recovery of carbonate reservoir,but this new technology is not used on internal oil field.Firstly,this paper introduces the pivotal technology about coiled tubing tunneling that includes Process scheme,downhole tools,enhancement mechanism,technology features,selection of coiled tubing equipment,operation procedures and so on.Lastly,based on specific field operations in oversea,the viability and existent problems about coiled tubing tunneling technology are also discussed in this paper.
