摘要
对于特低渗透油藏, 常规压力注水已不能满足生产要求, 必须采取高压注水, 但是高压注水会使管柱发生较大变形, 而常规的强度校核方法也受到公式适用范围的限制。以油田常用的高压注水管柱为例, 详细阐述了高压注水条件下管柱变形及强度校核的计算方法。
Abstract
The conventionality pressure o f wa ter injection can not
satisfy production requirem ent in low perm eability reservoir.
W e must increase the pressure, but it w ill make pipe str ing
d istort greatly ifw e compute the biggest stress from pipe str ing
in o rd ina ry w ay. It is not co rrect. In th is paper, the autho r
w ill take common high pressure p ipe str ing as an ex amp le to
illustrate the accurate m ethod for computing stress and
d istortion quan tity.
