摘要

通过对高压注水时砂岩的垂向形变特征和拉应力作用下套管强度性能的理论研究和计算,得出了高压注水对砂岩层段套管损坏的机理。以大庆榆树林油田砂岩段的套损情况为例,计算了注水压力、套管应力及套管强度之间的关系。

Abstract

Based on the theoretical study and calculation on the characteristic of vertical deformation of sandstone under high pressure water injection and properties of casing strength under axial extent stress, this paper introduces the mechanism of casing deformation in sandstone under high pressure injecting. As an example, Shuangyushu oilfield in Daqing is used to demonstrate the relationship between water injection prbssure, casing stress and casing strength.
