摘要
从分析井壁围岩的应力出发,建立了地层倾角对地层坍塌压力影响的力学模型和坍塌准则,江苏油田桥7井地层坍塌压力计算实例表明,地层倾角对地层坍塌压力有较大影响,因此在研究地层坍塌压力过程中应充分考虑地层倾角。
On the basis of well rock stress analyses, a mechanical model and collapsed criteria for the effect of formation dip on collapsed pressure is established. Calculation of practical data from well Qiao 7 of Jiangsu oilfield demonstrates that formation dip is an effective and important parameter in the study of formation collapsed pressure.
