| 1. | The preferred fault control of coal - gas outburst in north henan s 1 area 豫北二1煤瓦斯突出的优势断裂控制 |
| 2. | The long developing major faults controls the subsidence of the depression and the depression of the formation 长期发育的主干断层控制着凹陷的沉降和地层的沉积。 |
| 3. | The regional faults controlled the distribution of the facies , and the shaoxin - yichun fault controlles the evolution of the palaeogeography in the two sides of the fault 在整个三叠纪,区域性大断裂对沉积相的分布具有显著的控制作用。 |
| 4. | It was considered that karstification is the base of reservior formation , and lithology and faulting control the formation and development of internal reservior 其发育规律为:岩溶作用是下古生界储集层发育的基础;岩性和断裂作用决定内幕储层的形成与发育。 |
| 5. | After recombination of faults according to new penetrated breakpoints data , the number , extension length and trend of some faults controlled by original patterns changed 根据新钻遇中断点资料对断层进行重新组合,原井网条件下控制的部分断层的数量、延伸长度、走向发生了变化。 |
| 6. | The faults controlled the mineralization mainly and connected the deep with the surface by the upward migration of the deep - derived auriferous metallogenetic fluids via the fractured zones and by their later precipitation 提出了断裂构造对成矿的主要控制作用,它起着沟通深部与浅部的作用,并使深部的含金流体沿断裂破碎带上升、沉淀而成矿。 |
| 7. | The source faults control oil gas accumulation and distribution in the research area : 1 ) the nearer to the source faults is , the higher the oil - gas accumulation degree is ; 2 ) the smaller fault displacement of the source fault is , the higher oil gas output near the source fault is 源断裂控制着贝尔凹陷布达特群油气成藏与分布,主要表现在距源断裂越近油气富集程度越高及断距越小的源断裂附近油气产量越高2个方面。 |
| 8. | The fault controlled the magmatism and metallization relevant to the contact zone , and deformed successively and produced cataclastic rocks and two sets of joints ; the second stage was from late cretaceous to eocene . the fault zone deformed right - laterally under ne - sw striking transtention , and new joints zone was produced at the end of the two main faults because of local stress concentration . the fault produced inchoative cataclastic rocks , and two sets of typical joints in plutons ; the third stage of deformation was relatively faint and only a little of microcracks was produced and infilled with vei ns in the deformed rocks , which was during the himalayan movement 其后的继承性活动在断裂带内形成碎裂程度最强达到碎裂岩的碎裂岩系列构造岩,变形带两侧发育两组典型的共轭剪节理;第二次在晚白垩世?始新世,断裂在北东?南西向近水平挤压作用下右行张扭性活动,断裂带两主断裂在斜列重叠的端部由于局部应力集中进一步扩展形成节理带,而断裂在岩体区也发育两组典型的共轭剪节理,断裂内形成初碎裂岩为主的构造岩;第三次是喜山期以西侧抬升、东侧下降的强烈升降为主的活动,在基岩中,主断层两侧围岩出现微破裂。 |
| 9. | 5 . by summarizing the distribution regularity of existing oil & gas fields , it is found that all kinds of oil & gas reservoirs are distributed around the qikou depression like rings , which are divided into inner ring oil - bearing belt , infer ring oil - bearing belt and outer ring . the inner ring is central of oil - bearing region in qikou depression , which is controlled by haihe faults and qidong faults . the inter ring is in regions which are prospect for oil and regions with paleogeographic background of low - gradient slogze . the outer ring is regions . which are outside the oil - bearing region and inside the oil & gas migration region , with paleogeographic background of buried - hill and faults controlling the basin , ect 5 、通过对已知油气藏分布规律的总结,发现各类油气藏围绕歧口凹陷生油中心呈环带状分布,分为内环、中环、外环三个含油带。内环为海河断裂和歧东断裂控制的歧口凹陷生油中心区,中环为有利生油区范围内和缓坡古背景上的地区,外环为生油区范围以外、油气侧向运移范围以内的以古潜山为背景或控盆断裂带等区域。 |
| 10. | Northeast faults control the spread of the anhui riverway , and eastwest faults resulted in the widening of the river and the occurrence of nodes , then the stream raised and the riverway turn into goose pattern braided river . northwest faults and northsouth faults influence the evolvement of partial riverway , for example , the northwest lujiang - zhongming fault influence the evolvement of tongning shoals , and the northsouth faults passing through zongyang - digang make the riverway ' s direction from north - east to north - south 北东向断裂构造控制了皖江河型的展布;东西向断裂构造影响河道的拓宽,形成矶头,矶头挑流进一步使河道形成稳定的鹅头型;北西、南北向断裂影响局部河道的发育演变,如北西向庐江-钟鸣断裂影响铜陵沙洲的发育演变,南北向断裂影响枞阳、铜陵、获港河道使其延伸方向由北东转向南北向。 |
