摘要/Abstract

摘要： 文中应用动坐标迭代法分析环空大挠度钻柱受力与变形理论,将摩擦引入平衡计算,对大港油田女MH—1水平井下部钻具组合进行优化计算和事后分析。计算与观场施工相吻合,说明所用钻具都比较合理。

关键词: 水平钻井钻具组合事后分析

Abstract:

This paper uses moving coordinate iteration method to analyze the theory of forces and deformations of a large deflection drill string , and makes the optimization computation and poat analysis of bottom-hole assembly (BHA) in Nu MH-1 horizontal well in Degang oil Fi eld by introducing friction into balance computation. The computation results are in agreement with the field BHA, thus indicating all the drilling tools used are more reasonable.

Key words: Moving coodrinate iteration method, Bottom-hole assembly, post analysis
