| 2. | Distribution and burying characteristics of the permo - carboniferous system and the coal - formed gas source rock in jiyang depression 济阳坳陷石炭二叠系埋藏条件及煤型气源岩分布特征 |
| 3. | Coal , carbargilite in permo - carboniferous and carbonate in ordovician system were the main source rock of natural gas in the researched area 石炭二叠系分布的煤层、炭质泥岩和奥陶系碳酸盐岩是研究区主要的气源岩。 |
| 4. | This paper introduces the half peak width method ( ki index ) which is widely used in the or1d to analyze the permo - carboniferous sample from budate group in geier sag in hailaer basin and northern songliao basin 引入国际通行的半峰宽法( ki指数法) ,对海拉尔盆地贝尔凹陷布达特群和松辽盆地北部石炭二叠系的样品进行了分析。 |
| 5. | The non - linear optimum inversion technique has achieved a fine result in predicting the distribution of the oil - bearing formation of permo - caboniferous in the south hexiwu structural zone , and provided the important data for promoting the rolling exploration in the district 应用非线性最优化反演技术预测河西务南部石炭二叠系的含油储层分布取得了良好的效果,为本区滚动勘探的突破提供了有力的决策依据。 |
| 6. | Under the guide of dynamic system for pool - forming and petroleum system , this research has fully taken advantage of every kinds of data from the area , applied the new idea , new technology , new methods to study tectonic , sedimentary and resource rock . the results suggest that the source rock of permo - carboniferous has undergone three evolution periods . the first gas generation occurs at the end of triassic and the generation stopped during jurassic - cretaceous 该文以成藏动力学系统和含油气系统理论为指导,充分利用工区以及邻区的各种资料,运用新思路、新技术、新方法,在构造、沉积、烃源岩评价等基础地质研究的基础上,认为石炭?二叠系烃源岩经历了三叠纪末期以前的一次生气阶段、侏罗纪?白垩纪时期的演化停止阶段和早第三纪至今的二次生气阶段等三个阶段。 |
| 7. | On the basis of analyzing and chemically examining a large numble of samples , through comprehensively studying the reservoiring geological conditions as hydrocarbon generation , petrophysical property , reservoir - caprock assemblage and lithologic trap type , by use of mathematical statistics , it was considered that yulin gas field is located in the greatest hydrocarbon - generating intensity area in the basin and its hydrocarbon source rocks are the permo - carboniferous coal measure strata , thus possessing the material conditions of forming large - sized gas fields 通过大量的化验分析样品数据,采用数理统计的方法对生烃条件、储层物性、储盖组合配置、岩性圈闭类型等成藏地质条件进行了较为深入的研究,认为榆林气田处于鄂尔多斯盆地最大生烃强度区,其烃源岩为石炭二叠系煤系地层,具备形成大型气田的物质条件。 |
| 8. | Kongxi buried hill shows following features in the seismic profiles : the structures are asymmetric . there is flexural syncline on the east side and a monocline on the west side . asymmetric repetition of stratigraphic units is present in the drill wells and the dips of beds and faults are gentle . the permo - carboniferous system of both sides almost lie in the same slope and the events of cambrian or upper proterozoic are continuous from east to west . the phenomenas suggest that kongxi buried hill could be a thrust belt been traced which consists of reverse faults . the imbricate faults mainly effect pre - jurassic strata . there are obvious angular unconformity between jurassic - cretaceous system and paleozoic involved deformation of thrust . the thrust front in some place has cut off the beds of jurassic - cretaceous system . the structural style of the thrust structure changes along the strike of the kongxi buried hill 地震和钻井资料揭露的孔西构造带前第三系潜山的地质特征可以归纳为:构造带总体上不对称构造带内部有地层重复现象石炭二叠系地层的位置明显高于两侧的同一地层的高度。用由34条向东倾斜的逆冲断层组成的叠瓦扇构造模式能够比较合理地解释上述地质特征。该带向东倾斜的逆冲叠瓦状断层组主要影响前侏罗系地层,侏罗白垩系与卷入逆冲构造变形的古生界地层之间有明显的角度不整合。 |
| 9. | This paper emphasize the research of geometry , kinematics , age of formation of oblique - thrustin . it is discussed that geological significance of obligue - trusting . ( 1 ) this paper classified the strata of sertengshan - xitieshan in northern qaidam basin into daken - dabanyan group in lower proterozoic , tanjianshan group in ordovician - silurian period , aimunike group in upper devonian period and guokesan formation of zhongwu - nunsan group in permo - carboniferous ( 1 )对柴达木盆地北缘的赛什腾? ?锡铁山一带出露的地层进行了较为系统的划分,厘定了古元古代达肯大坂岩群、奥陶? ?志留纪滩间山(岩)群、泥盆纪上泥盆统埃姆尼克群、石炭? ?二叠纪中吾农山群果可山组。 |
