| 摘 要： | 山东济阳坳陷构造特征复杂,利用地震勘探方法预测潜山裂缝的难度大。由于构造裂缝主要受控于构造应力场,从构造应力场分析入手预测构造裂缝发育规律是十分有效的手段。利用电阻率成像测井资料对济阳坳陷桩海地区井下构造应力场进行研究,研究结果表明:该区井下应力场十分复杂,井旁构造受断层影响较大,各层段地层倾向和裂缝方位变化较大;桩海北部地区现今最大水平主应力的方向为北西西—南东东向,桩海南部地区现今最大水平主应力的方向为北东东—南西西向。 |

| Abstract: | The structures of Jiyang depression are very complex, so it is difficult to predict the fractures deve-(loped) in the buried hill by seismic data.The fractures are always controlled by the tectonic stress distribution;therefore,to study the paleo-stress field is a useful method to predict the fractures.In this study,the borehole tectonic stress of Zhuanghai area was analyzed by FMI images.It was found that the directions of stress fields were variable and the structures near the boreholes were influenced by the faults.The dipping direction of the strata and fractures changed intensively.The present direction of the principle horizontal stress is NWW-SEE in the north of Zhuanghai area,while the direction is NEE-SWW in the south area. |
