| 1. | It is claimed that more petroleum may be preserved in stratigraphic than in structural traps . 有人主张,地层圈闭也许比构造圈闭存有更多的石油。 |
| 2. | Paleogene lowstand system tract deposits and nonstructural traps in dongying sag 东营凹陷下第三系低位域沉积及非构造圈闭 |
| 3. | The structure model shows the sometimes normal and sometimes reverse characteristics of jiazhangsi fault , which is the control fault of the reservoir 构造模型清晰地展示了控藏断层驾掌寺大断裂时正时逆的特点,解决了深浅层构造圈闭差别大的问题。 |
| 4. | The activity of exploration for oil and gas all around the world can be divided into three stages i . e . early stage for tectonic traps , the middle stage for complex traps and the late stage for lithologic - stratigraphic traps 国内外大量油气勘探研究成果表明:任何一个地区的油气勘探都要经历三个阶段,即早期的构造圈闭勘探阶段,中期的复合圈闭勘探阶段和晚期的地层岩性圈闭勘探阶段。 |
| 5. | The envelop capacity of seal influence the formationand and scale of reservoir . the main kind of trap is structure trap as anticlinal or fault anticlinal with high closure height and big area . so the trap is put into effect and its formation match the period of hydrocarbon runoff 孔雀河斜坡圈闭类型以背斜和断背斜等构造圈闭为主,闭合面积幅度大,落实程度较高,而且圈闭形成期与排烃期相匹配,在现阶段圈闭条件不是影响成藏的主要因素。 |
| 6. | The result shows that the hydrocarbon resources are abundant , physical properties of the reservoirs are mainly of mid - porosity and mid - low permeability reservoirs , its trap types are mainly of overlying pinchout lithological traps and structural or lithological - structural traps , accumulation conditions are good 结果表明,研究区油气资源丰富,储层物性主要为中孔中低渗储层,圈闭类型主要为砂岩上倾尖灭的岩性圈闭和构造或岩性构造圈闭,成藏条件较好。 |
| 7. | The reservoir is located at yishan slope area between jinxi fold belt and tianhuan depression , it has the characters of less structural deformation , overlying hydrocarbon genetic center in upper and lower palaeozoic era , growth of high efficient reservoirs and as well as fast lateral changes of reservoir physical properties , it has the condition of forming non structural traps , which is the major area for gas reservoir exploration in the basin 位于晋西挠褶带和天环坳陷间的伊陕斜坡区,因具有构造变形微弱,上、下古生界生烃中心叠置,高效储层发育,储集层物性侧向变化快等特点,具备形成非构造圈闭优越条件,为盆地气藏勘探约重点区带。 |
| 8. | ( 4 ) the formation and growth of structural traps and stratigraphic - unconformity traps in the area is controlled by three compressive stages of silurian - devonian , late permian - tertiary and oligocene - quaternary ; non - structural and compound traps mainly grew in the early paleozoic . structural traps mostly grew in the late paleozoic and the cenozoic and mostly grew on the north and south belts ; non - structural traps mostly grew in the northern area of the hetian concave . most traps in the area formed or typed at last in the himalayan episode , dispersed on the north and south belts ( 4 )研究区构造与地层不整合圈闭的形成和发育受志留-泥盆纪、晚二叠世-第三纪、渐新世-第四纪三个挤压阶段的控制;早古生代主要发育非构造圈闭和复合圈闭,晚古生代和新生代则主要发育构造圈闭:构造圈闭主要发育在南北两带上,其次为中带;非构造圈闭主要发育在和田凹陷以北的地区;研究区内大多数圈闭是喜山期形成或最终定型的,在南北两带都有分布,而海西期圈闭主要分布于研究区中带玛南构造带处。 |
| 9. | On the base of description and analysis of main fractures time - space developmental characteristics , this paper further expound formation mechanism of these two suites of fractures and control action of structure trap , favorable sedimentary facies distribution , process of hydrocarbon migration and accumulation , degree of hydrocarbon preservation and mineral dressing 在对柴西南区主要断裂时空发育特征描述与分析基础上,进一步阐明了这2组断裂的形成机制和对柴西南区构造圈闭、有利沉积相带、油气运聚成藏过程及油气藏保存、富集等成藏要素的控制作用。 |
| 10. | The distributions of source rocks , reserviors and faults / fissures , and conservation are the critical factors in poolforming and enrichment of gas in the foreland basin . 6 . the thrust belts of longmen mountains are potential prospects in the basin with the concentrated structural traps , strucrural - fissuring traps , and faults connecting between the shallow and middle formations 6 、龙门山山前冲断带具有较大的油气潜力,构造圈闭、构造-裂缝型圈闭发育,中浅层构造同步发育或有断裂沟通,具有中浅层均含气的特征。 |
