| 中文摘要: |
| 金沙—仁怀地区发育较好的生储盖组合，具有较好的油气地质条件，但由于构造等作用导致该区油气保存受到不同程度的影响，使得保存条件成为该区油气勘探最为关注的一个重点问题。文章从盖层特征、断裂构造特征和热液活动特征等3个方面对区内油气保存条件开展研究，并在此基础上将金沙—仁怀地区划分为3个油气保存区块：黔北隔槽式褶皱区、大方—安底低潜构造区以及构造热液破坏区。通过对不同区块内的保存条件综合分析评价认为，大方—安底低潜构造区内油气保存条件良好，且已发现较好的油气显示，表明该区块可能具有良好油气勘探前景，值得深入开展勘探工作。 |
| 英文摘要: |
| In Jinsha-Renhuai area exists good reservoir-cap portfolio and geological condition of oil and gas generation but due to tectonic and other factors the preservation conditions are subject to different degrees of damage. The preservation condition becomes one of the key exploration problems. In this paper the preservation conditions are studied in three aspects of cover, fault and hydrothermal activity. According to the study the Jinsha-Renhuai area is divided into three blocks: the wide spaced syncline belts of northern Guizhou, Dafang-Andi low latent structure, Tectonic and hydrothermal area. Comprehensive analysis of preservation condition in different blocks shows that the preservation condition within Dafang-Andi block is ok and netter oil gas indication has been discovered there thus it is potential for further prospecting. |
