摘要/Abstract

摘要： 针对连续油管输送分簇射孔管柱存在下井遇卡的问题,考虑井眼轨迹、井筒约束、工具串变径结构、工具变形及连续油管屈曲效应等作用的影响,采用微元法建立连续油管输送分簇射孔管柱通过能力分析模型,分析连续油管输送1桥塞+2簇射孔枪管柱在井筒中的通过能力。研究表明:作业工具串下入过程不会遇卡,连续油管输送分簇射孔管柱能够下至预定井深3 850 m;直井段越长、水平段越短的井眼轨迹越有利于管柱的下入;射孔分簇数量越少、射孔枪规格越小、连续油管规格越大的管柱通过性更好。该分析方法可为现场连续油管射孔管柱作业参数优选和操作提供技术支持。

Abstract: To address the problem that the coiled tubing gets stuck in wells when conveying the clustered perforating string, considering the influence of wellbore trajectory, wellbore constraint, tool string variable diameter structure, tool deformation and coiled tubing buckling effect, the micro-element method was adopted to establish an analysis model of the passability of the coiled tubing conveying clustered perforating string to analyze the passability of the coiled tubing conveying 1 bridge plug + 2 clustered perforating guns string in the wellbore. The research shows: The operation tool string will not be stuck during the running process, and the coiled tubing conveying clustered perforating string can go down to the predetermined well depth of 3850m; the longer the vertical section and the shorter the horizontal section, the better the wellbore trajectory is for running the pipe string; the smaller the number of perforation clusters, the smaller the size of the perforating gun, and the larger the coiled tubing size, the better the passability of the tubing string. The analysis method can provide technical support for the operating parameters optimization and operation of the coiled tubing conveying the perforating string on site.

Key words: clustered perforating string, coiled tubing, wellbore trajectory, buckling effect, horizontal well
