目的
2
针对多级压裂过程中由封隔器系统诱发的管柱强度失效问题,开展了管柱力学行为与强度影响规律研究,以保障压裂作业安全性与管柱结构可靠性。
方法
2
首先,基于多级封隔器工作特性,建立了压裂管柱系统力学模型,并推导了坐封与压裂两种工况下的控制方程。其次,采用有限元方法,将封隔器位移作为压裂工况的初始边界条件。然后,考虑了封隔器滑移与固定的非确定性边界条件,构建了多级压裂管柱系统的数值计算方法。最后,以现场某口井为实例进行了计算分析。
结果
2
分析结果表明,随着压裂级数增加,井口轴向力与等效应力显著上升,安全系数逐步下降;压裂液流量、井口压力与砂比对管柱强度均具有显著影响,任一参数的增大均会引起轴向力增加和安全系数下降,从而加剧管柱强度失效风险,并为多级压裂管柱强度设计与安全评估提供了依据。
Objective
2
Aiming at the string strength failure problem induced by the packer system during multi-stage fracturing
the investigation on the mechanical behavior of the string and the influence law of strength was carried out to ensure the safety of fracturing operations and the structural reliability of the string.
Methods
2
Firstly
based on the working characteristics of multi-stage packers
a mechanical model of the fracturing string system was established
and the governing equations under the two working conditions of setting and fracturing were derived. Secondly
the finite element method was adopted
and the packer displacement was taken as the initial boundary condition of the fracturing working condition. Then
the non-deterministic boundary conditions of packer sliding and fixing were considered
and a numerical calculation method for the multi-stage fracturing string system was constructed. Finally
calculation and analysis were carried out through field well cases.
Results
2
The analysis results showed that with the increase of fracturing stages
the wellhead axial force and equivalent stress increased significantly
and the safety factor decreased gradually; the fracturing fluid flow rate
wellhead pressure and proppant concentration all had significant effects on the string strength; the increase of any parameter would lead to the increase of axial force and the decrease of safety factor
thereby aggravating the risk of string strength failure. The research results provided a basis for the strength design and safety evaluation of multi-stage fracturing strings.
