| 摘 要： | 从力学角度对DY地区井下复杂情况进行研究。结合声波时差和密度测井资料,运用ADS法间接求得现今地应力值。在此基础上,建立最小水平主应力与破裂压力的关系,并依此关系确定破裂压力的大小。运用经典岩石坍塌压力计算模型得到DY地区连续的坍塌压力剖面。通过实钻资料验证,证实了评价DY地区须家河组地层井壁稳定性方法的可行性和可靠性。

| Abstract: | From a mechanical point of view, downhole problems of DY region have been studied in this paper. First, the presentday stress value was obtained indirectly by using the ADS combining with acoustic data and density log data. Based on this, the relationship between minimum horizontal principal stress and breakdown pressure was established, and value of the fracture pressure was obtained. The continuous collapse pressure profile was obtained by calculation model of classic rock collapse pressure in DY. It was confirmed by drilling data the feasibility and reliability of borehole stability evaluation method of Xujiahe Formation in DY area. |
