这是对前人观点的重要改进和补充，也对整个勒陷袖气勘探具有十分重要的意义。 |
| 4. | As a result of complicated geology environment , many geology hazards frequently happen such as landslide in wushan county . furthermore , sidaogou landslide is one of the most important landslides that are relevant to the stability of wushan new county
由于其复杂的地质环境，巫山县城是滑坡等地质灾害的多发城市，四道沟滑坡是关系到巫山新县城稳定性的最重要滑坡之一。 |
| 5. | Sidaogou landslide situated at the north of yangtze river and the southwest of wushan new county , whether the landslide is steady or not relates to the reliability of bank reconstruction , dock building , roadbed along yangtze and the safety of the life and estate in the landslide area
四道沟滑坡位于长江北岸、巫山县新城区之南西边缘，该滑坡的稳定与否关系到库岸再造、码头兴建以及沿江路基稳定的可靠度和滑坡区内人民群众生命财产的安全。 |
| 6. | ( 5 ) discovered a abnormal law that the sonic velocity was enlarged with increasing of die core porosity in the sandstone reservoir of the haojiagou formation in triassic , and gave a geologic interpretation about the phenomenon . it was helpful to convert the sonic velocity into die porosity correctly in reservoir . ( 6 ) gave a primary reason for producing a little oil and gas in the well ha - 2 and ha - 3 of the sidaogou structure
通过取心段地层岩性与声波测井速度分析，首次发现郝家沟组储层段岩芯孔隙度与声波时差(声波速度)存在反常变化规律，并对这种现象进行了较合理的地质解释；提出了储层预测中应注意的问题，首次提出在本区按常规方法利用声波时差换算孔隙度存在陷阱。 |
| 7. | But with the increase in the hardness of petroleum exploration , the experience and lesson in the petroleum exploration history over the world ask to develop early reservoir description in the preparatory reconnaissance stage . it can reduce the risk of exploration and improve the exploration benefit significantly . therefore by explaining the definition , significance and task of early reservoir description , this paper proposed a systematic thought and method about early reservoir description , and applied in the sidaogou structure of the hami depression
但随着油气勘探难度的加大与勘探风险的增加，以及国内外众多油气田勘探成功与失败的经验教训表明，在新区油气予探阶段就开展早期油藏描述工作已变得十分必要，它不仅可降低勘探风险，提高勘探成功率和勘探效益，而更重要的是可使我们在油气勘探初期少走弯路。 |
| 8. | This paper also summarized a way how to do the early reservoir description in the preparatory reconnaissance stage . in the paper author provided a detailed study of sedimentary facies , reservoir , the forming conditions of hydrocarbon pool , structure feature and reservoir prediction about the sidaogou structure , and point out the primary reason for producing a little oil and gas in the sidaogou structure , and gave the main direction for the future petroleum exploration in the hami depression
因此，本文系统地阐述了早期油藏描述的定义、意义和任务，建立了早期油藏描述较完整的研究思路和研究方法，并通过对吐哈盆地哈密坳陷四道沟构造低产油气藏的早期油藏描述具体研究工作，摸索和总结出一套如何将早期油藏描述技术应用于油气藏预探阶段的研究方法。 |
| 9. | The direction of migration was in east and northeast . ( 3 ) this paper introduced the balanced section into the early reservoir description in the sidaogou structure for the first time , and gave a new viewpoint that the sidaogou structure was a fault - bend fold formed by two step thrust fault . the structural stress direction came from the northeast of the hami depression
首次将平衡剖面技术引入了四道沟构造早期油藏描述的构造研究之中，并首次提出四道沟构造是?至少由两个阶梯状断层组成的后倾双重构造叠加的断层转折褶皱，构造应力方向应大致源于北东方向。 |
| 10. | When the three - gorge reservoir is sluiced , the underground water level will ascend obviously and mechanics parameters of the slip strip below the reservoir water level can drop further , sidaogou landslide can lose stability wholly in controlled condition influenced by buoyancy of underground water and saturation stress at water level dropping
三峡水库蓄水后，滑体内的地下水位将明显抬高，库水以下的滑带力学参数会进一步降低，受滑体内地下水扬压力及水库水位降落时渗透压力的影响，四道沟滑坡在控制工况下可能整体失稳。 |
