| 9. | Through studying it is shown that in chagan sag , the geothermal gradients in the center are higher than those around the sag margin and major factors influencing the characteristics of temperature field distribution are the property of geotectogenesis and the differences in tectonic portion , lithology and underground water behaviour ; there are three types of mudstone compaction , i . e . normal compaction , undercompacition and overcomepaction ; there are two pressure systems in sandstone reservoirs , i . e . normal pressure and negative pressure systems and the strata ' s being uplifted and denuded is the key factor leading to the formation of the negative pressure system in reservoir ; and the distinctive temperature - pressure field characteristics in the sag are possessed of important petroleum geological significance in hydrocarbon source maturity , hydrocarbon generation , widening on oil and gas exploration domain and selecting exploration targets , etc
研究表明，查干凹陷中心的地温梯度高于凹陷边缘，大地构造性质及所处构造部位、岩性与地下水活动的差异是影响凹陷地温场分布特徵的主要因素；泥岩压实存在正常压实、欠压实和过压实三种类型，砂岩储层段压力类型可分为正常和负压两个系统，地层抬升剥蚀是导致储层负压系统形成的主导因素；凹陷独特的温压场特徵对烃源岩成熟、油气生成、油气勘探领域的扩大及勘探方向的选择等具有重要的油气地质意义。 |
| 10. | Yinggete - bagemaode metamorphic core complex belt with three - layer construction is put forward , which evolved from late jurassic to cretaceous . the extensional simple shear model of the chagan fault depression is established . the tectonic evolution and the dynamics character of chagan fault depression and its adjacent mesozoic - cenozoic basins are discussed : at the end of triassic continental orogeny increased crust thickness crust uplift and denudation were happened ; jurassic was a period of local partly extensional collapse of erogenic belt and cretaceous was a period of widely extensional collapse of postorogenic erogenic belt ; cenozoic was a period of the development of stable intracontinental depression with the character of long distant collision response and weaked compression flexure
