Simulation and Experimental Study on the Safe Application Condition of Expandable Profile Liner in Slim Holes

Sinopec Research Institute of Petroleum Engineering, Beijing, 100101, China

摘要

摘要: 膨胀波纹管可以用于封隔小井眼斜井段坍塌煤层和泥岩，为解决地层坍塌问题提供了新的手段，但其适用工况不确定，影响了其推广应用。为确定膨胀波纹管在小井眼的安全应用工况条件，应用有限元法模拟分析了影响斜井段中φ149.2mm膨胀波纹管安全应用的主要因素；在弯曲井筒内开展了膨胀波纹管的膨胀试验，分析了井眼曲率、井径对膨胀效果的影响。研究结果表明，在相同条件下，井径越大，波纹管膨胀后的直径越大；井眼曲率越大，膨胀波纹管Mises应力越大，不圆度越大。试验和数值分析结果表明，二者有着较好一致性。通过分析确定了φ149.2 mm膨胀波纹管安全应用工况条件，可以保障膨胀波纹管的安全施工。

Abstract: Although the expandable profile liner technology has been successfully applied to sealing collapsed coal seams and mudstones in inclined sections of slim holes and provides a new means to solve the formation collapse problem,the uncertainty of applicable working condition limits the widespread use of the technology.To determine the safe working conditions of expandable profile liner in slim holes and secure the application,the finite element method was used to simulate and analyze the influence factors for application of φ149.2 mm expandable profile liner in inclined sections.An expansion test of expandable profile liner was made in wellbore hole simulator to analyze the influence of borehole curvature and hole diameter on the application.Under same conditions,the greater the hole diameter was, the larger the diameter of the expanded liner wouldbe;the larger the borehole curvature was,the greater the Mises stress and the higher the ellipticity wouldbe.The results of the test and numerical analysis were consistent.The safe working conditions for the φ149.2 mm expandable profile liner were defined through analysis,thus the safe application could be guaranteed.
