摘要
在俄罗斯联邦和世界范围内，有一种使钻井技术复杂化的趋势。这是由于水平井数量的增加和分支井长度的增加造成的。在斜井和水平井下入过程中，带螺纹连接的套管承受轴向载荷、弯曲载荷、压差等综合载荷。套管柱最关键的环节是螺纹连接。连接压缩效率达不到50% ~ 80%。本文描述了API Buttress和TMK UP CWB连接的有限元分析结果，以及TMK UP CWB 177.8 × 9.19 N80的全尺寸试验结果。
Performance of casing connection for horizontal oil wells
Summary There is a tendency to complicate drilling techniques in the Russian Federation and in the world. It is caused by increase the number of horizontal wells and increase the length of the laterals. Casing with thread connections while run in hole operation in deviated and horizontal wells are subjected to combined loads caused by axial load, bending load, differential pressure. The most critical point of casing string is the thread connection. 50%-80% compression efficiency of connection becomes insufficient. This article describes results of FEA (finite element analysis) for API Buttress and TMK UP CWB connections and full scale test for TMK UP CWB 177.8 х 9.19 N80.
