随着我国经济的迅速发展以及科学水平的进步,我国的石油工业取得了巨大的发展。而在石油工业中,对于定向井套管应力随地应力条件的变化规律研究是比较重要的。目前状况下,我国对于相对复杂条件下的直井套管的损伤问题的研究已经取得了一定的成果。而对于相应的定向井情况的研究却十分稀少。
With the rapid economic development in our country and the progress of science, China’s oil industry has made tremendous progress. However, in the petroleum industry, it is more important to study the variation rules of the casing stress in the directional well under the conditions of in-situ stress. Under the current situation, some achievements have been made in the study of the damage of straight-hole casing under relatively complicated conditions in our country. However, the research on the corresponding directional well situation is very rare.
