| 中文摘要: |
| 博乐盆地是天山构造带的山间盆地,在古地理环境上,处于残余洋盆南部边缘的浅海区,区域构造特征严格控制着有机质的堆积、保存和转化；温泉坳陷位于汗吉尕山与阿拉套推覆体形成的一个“对冲”构造格局下。博乐盆地温泉坳陷发育富有机质暗色泥页岩,具有良好的生烃条件。是最有利于油气生成的古地理区域。通过开展重力、磁法以及电磁勘探等综合物探工作,建立该区岩性、地层密度、磁化率、电阻率反演模型。结合已知资料,勾画出了典型的地质构造剖面,为建立博乐盆地晚古生界—中新生界沉积充填系列,研究 研究页岩气富集规律,评价盆地页岩气资源潜力,进一步开展页岩气勘查提供地球物理和地质依据。 |
| 英文摘要: |
| Bole Basin is a mountain basin in the Tianshan tectonic belt. In the ancient geographical environment, it is located in the shallow sea area on the southern edge of the residual ocean basin. The regional tectonic characteristics strictly control the accumulation, preservation, and transformation of organic matter. The hot spring depression is located under a "hedging" structural pattern formed by Khan Jijia Mountain and Alatao. Dark mud shale rich in organic matter developed in the hot spring depression of Bole Basin has good hydrocarbon producing conditions. It is the paleogeographical area that is most conducive to oil and gas generation. The model of lithology, formation density, magnetization and resistivity inversion in this area was established through the work of gravity, magnetic method and electromagnetic exploration. Based on the known data, the typical Geological structure profile is outlined, and the Geophysical and geological basis is provided for the establishment of the Late Paleozoic-Mesozoic sedimentary filling series in the Bole Basin, the law of shale gas enrichment is studied, the potential of shale gas resources in the basin is evaluated, and further shale gas exploration is carried out. |
