水平井压裂起裂规律研究现状

Research advance of the fracture cracking laws in horizontal well

介绍了国内外在水平井压裂裂缝起裂规律的研究进展,主要包括运用解析法和有限元法两种不同方法,研究了水平井井筒周围地应力分布对裂缝起裂的影响,破裂压力及起裂方位,指出了目前研究中的不足,并对未来的研究方向进行了分析和展望。

This paper introduces the domestical and foreign research progress of cracking laws to the horizontal wells when fracturing,It mainly includes using the analytical method and the finite element method,which studies the impact on cracking caused by the Stress distribution near the wellbore of horizontal wells,while the research of burst pressure and cracking location,It also indicates the drawbacks in the current research,analyzes and forecasts the future research directions.
