摘要
用钻孔崩落分析程序处理冀中坳陷６７口井的四臂双井任测井资料，分析其水平主应力方向。结果表明，该区水平最大主应力方向总体近东西向，存在明显的局部应力方向变化；并存在水平主应力方向随深度而变化。本文讨论了应力场的地区差异在油田开发中的可能应用。
Hole diameter data from four-arm dipmeter logging in 67 oil wells in Jizhong depression, Hebei province, were processed with computer programs I which the authors developed previously, and orientations of horizontal principal stress axes were derived for the depression region. The result indicates that on the average the maximum horizontal principal compressive stress is oriented N85°E for the whole region, while significant local variation of stress orientations can also be seen. The present study has also found the cases that SHmax direction vary continuously or discontinuously with depth. Finally,the possible application of the knowledgeon local stress variation to oil and gas exploration and production is discussed.
