| 摘 要： | 针对古构造应力场反演计算中建立“古构造模型”和“约束条件”时所存在的问题,本文提出了应用三维地震资料进行古构造应力场反演的思路和方法,并以富台潜山为例,阐述了如何用三维地震资料来解决古构造应力场研究的“定时”、“定向”和“定量”问题。胜利油田富台潜山研究的实践表明:三维地震资料可以用来较好地解决古构造应力场研究中的“三定”问题,其结果的可靠性总体可以得到保障。因此,据于三维地震资料精细解释而进行的古应力场数值反演是古应力场研究的有效途径,同时也为裂缝的预测提供了基础。

| Abstract: | In view of problems existing in “paleo-structure model” and “constraint condition” on paleo-tectonic stress field backward computation, ideas and methods which applied 3D seismic data to deal with paleo-tectonic stress field backward computation were proposed, and it was elaborated how used 3D seismic data to solve “timing”, “orientation” and “quantity” in paleo-tectonic stress field study in this paper. A case study on the Futai buried hill, Shengli Oilfield, indicated that the application of 3D seismic data might be relatively useful to solve “three determination” problems in paleo-tectonic stress field study , and the obtained results be of reliability. The results were as follows. 1)There were two episodes of structural deformation, namely, thrusting-folding in the Yanshanian orogeny during which the majority of fractures created, and extension-normal faulting in the Himalayan movement. 2)There were 5 types of structural trackway, namely, the main thrust, branch thrust fault, common thrust, fault propagation fold axis, and transfer faults, could be used to determine the principle stress direction of the Yan￣shanian orogeny, and their results were highly consistent. 3) On basis of fine interpretation of the 3D seismic data, the key problems existing in “paleo-structure model” and “constraint condition” on paleo-tectonic stress field could be solved. Therefore, paleo-tectonic stress field backward computation, which was an effective way in paleo-tectonic stress field study, could be applied validly, meanwhile, it also provided the foundation for the fissures’ prediction. |
