摘要
在调研国内外相关资料文献的基础上,对目前我国油气田所采用的主要的射孔技术包括负压、超正压、复合压裂、水力割缝以及过油管张开式射孔,作了一个详细的介绍,涉及到各射孔技术的原理、特点、适用范围及应用情况,也提到了国外一些比较先进的射孔技术如套管外射孔、连续油管输送等。最后,对各种射孔技术作了一个概括性结论,并指出应该推广应用最有潜力的三种射孔技术,同时加强国际合作,提高射孔水平。
Based on the investigation of correlative literatures at home and abroad, this paper introduces systematically the primary perforating technologies adopted in domestic oil and gas fields at present, including underbalanced perforation, overpressure perforation, compound fracturing, hydraulic cutting seam and through-tubing folding perforation. Moreover, the paper presents the principle, property, application of every domestic technologies as well as several advanced foreign technologies, such as external -casing and continuous tubing-conveyed perforation. Finally, it summarizes all perforation technologies and provides three technologies with the most potential application. It also points out to strengthen an international cooperation and improves a perforation level.
