摘要:

通过分析带扶正器套管柱的受力与变形,导出了套管柱在水平井中的摩阻计算模型。模型考虑了管柱单元体的刚性效应及套管扶正器的影响,同时对实测井斜数据进行平滑和插值处理。在克拉玛依油田的试验水平井HW701中用该模型开发的软件预测了完井套管柱下入的摩阻力和井口载荷,预测结果与实测结果吻合较好。

Abstract:

This paper analyzes the stress and deformation of casing string with casing stabilizers, deduces the calculation model of frictional drag of casing string in horizontal wells. The model takes into account the effect of stiffness of the string element and the effect of casing string stabilizers, and makes smoothing and interpolation to the measured well inclination data. The software based on the model is used to predict the frictional drag and hook load of running completion casing string in the experimental horizontal well (Well No. HW701) in Kelamayi oilfield, and the calculated results agree with the measured data.

Key words: Horizontal well, Casing running, Frictional force, Stress analysis, Casing string
