Dynamics Study of Cable-Fed Bridge Plug and Borehole Logging Coupling System for Ultra-Deep Horizontal Wells
摘要
Abstract
Based on the features of pumping-type cable perforation and multistage fracturing with soluble bridge plugs,the dynamics analysis is conducted on the activity of bridge plug tool strings inultra deep horizontal wells.A dynamic control method for pumping volume distribution throughout the well section and a calculation method for cable tension were established.The relationship between dogleg degree(rate of change of wellbore angle),well-bore inclination angle and pumping volume distribution,as well as related factors such as pumping volume distribu-tion,tool string length and gap width,and cable tension were analyzed.The results show that with an increase in dogleg degree,the pumping volume distribution almost shows a quadratic relationship,while the well slope angle and pumping volume distribution have a linear relationship.In addition,in straight well sections,the correlation between cable tension and pumping volume distribution is not significant,but in curved sections,there is a signifi-cant linear relationship between tension and pumping volume distribution,tool string length,and the cable tension increases approximately exponentially with the decrease of gap width.关键词
