In this research , some conclusions are followed : l ) in the tahe oilfield , multiphase tectonic movement and pleokarst were so deeply worked on the diagenesis that the types of diagenesis are various , and the relation of those are complicated 本次研究最终得出如下结论: 1 )研究区由于受到多期构造运动的影响,又受到多期古岩溶作用的叠加改造,成岩作用类型多样,关系复杂。
Fracture and unconformity do n ' t controlled distribution of structure bearing , but the distribution of oil - gas , composed network channel for oil - gas move , and formed a large of trap . 4 . three stages of hydrocarbon happened in silurian - devonian stratum 3不整合是构造运动的结果,它与断裂的结合为满加尔坳陷生成的油气向高部位运移提供了网络通道,同时也控制了大量地层圈闭的形成。
The lower paleozoic oil & gas exploration practices within and adjacent to the well li - 1 in the study area reveal that the preservative conditions are the key factors for petroleum reservoir generation , because the lower paleozoic has earlier hydrocarbon - generating times and had experienced reformations and destruction by multi - periodic tectonic movements 据研究区内利1井及邻区下古生界油气勘探的实践表明:下古生界成油气时间早,油气演化程度高,后期经多次构造运动的改造和破坏,能否成藏,保存条件是关键。
( 5 ) by analyzing the terrace in the lacustrine sediment of the ancient barrier lake , diexi , minjiang river , forming of the terrace is not only because of the intermittent arising of the tectonic movement , but also because of descend of the eroding normal covering resulting from destroying of the barrier lake ( 5 )通过对岷江叠溪古堰塞湖湖相沉积中的河流阶地分析可知,阶地的形成不仅仅是由于新构造运动的间歇性抬升作用,由于堰塞湖的溃决引起洪水下泄,导致河流侵蚀基准面的下降也可以形成阶地。
From the viewpoint of neotectonic movement , the formatio n and characteristics of natural landscapes controlled by neotectonic movement i n the strong crust raising area , slightly raising area , subsiding area and trans ition area of northeast poyang lake region are discussed , and some suggestions a bout tour land planning and development in different areas are made 从新构造运动的观点出发,讨论了在鄱阳湖东北地区新构造运动强烈抬升区内、沉降区内、轻微抬升区内及过渡区内的旅游自然景观的形成、特点,并提出了合理规划和开发不同区域内旅游用地的建议。
