| 1. | Experimental results indicate that the sealing capacity of bedding faults is so high that it greatly enhances that of its original rock 我们的数据证实,顺层断层具有较强的封闭能力,将大大地增强原岩层的封堵能力。 |
| 2. | To understand the control action of bedding faults during the formation of hydrocarbon accumulations , an experimental analysis on sealing capacity of bedding fault rocks was performed 摘要为了解顺层断层对油气成藏的控制作用,实验研究了顺层断层岩的封闭能力。 |
| 3. | Therefore , cap rocks with bedding faults can seal higher hydrocarbon column height and fluid pressure , and thus facilitates the formation of larger scale hydrocarbon accumulations 如果盖层中发育顺层断层,盖层的封盖能力将被大大改善,将能够封盖更大的油气高度或者流体压力,利于形成更大规模的油气藏。 |
| 4. | This is the other main reason for the overpressure in kuche depression to be preserved . we analyzed the effect of fracture in the gas deposit formation and hold that different kinds of fracture have different effect : hydrocarbon dissipation and relief effect of crossing salt bed faults that run through source rock , reservoir , and caprock ; filling effect of under salt bed faults that run through source rock and reservoir ; slippage faults that did not connect source rock have no effect to hydrocarbon accumulation and dissipation ; adjusting faults in reservoir have effect of adjusting formations for hydrocarbon distribution 分析了断裂在天然气成藏中的作用,认为不同类型的断裂在天然气成藏过程中的作用是不同的:贯通生、储、盖层的穿盐断层对油气散失和泄压作用;贯通源岩和储层的盐下断层对抽气运聚的充注作用;不连接源岩的滑脱断层对油气聚散无作用;储层内调整断层对油气分布起调整层位作用。 |
| 5. | The mechanisms summarized are as follows 1 ) compressional normal stress ; 2 ) ductile and / or viscous deformation in bedding fault since incompetent bed is susceptible to plastic flow ; 3 ) higher likelihood of clay / shale smearing ; 4 ) foliation fabric whose sealing capacity is enhanced greatly in direction perpendicular to foliation 其机理可归纳为四个方面: 1 )压性的正应力; 2 )以韧性及粘性变形为主,因为非能干岩层易塑性流变; 3 )涂抹效应强; 4 )面理化组构,垂直面理方向的封闭能力大大增强。 |
| 6. | We also summed up four kinds of faults combination transportation model : the model that under salt bed fault and crossing salt bed fault are connected by faults ; the model that under salt bed fault and crossing salt bed fault are connected by reservoir , the model that under salt bed fracture and crossing salt bed fracture are connected by reservoir and breakthrough faults at the top of the trap ; single crossing salt bed model 总结了库车坳陷存在的四种断层组合输导模式:即盐下断层通过断层与穿盐断裂相连的组合输导模式;盐下断层通过储层与穿盐断裂相连的组合输导模式;盐下断裂通过储层和圈闭顶部突破断层与穿盐断裂相连的组合输导模式;单一穿盐断层输导模式。 |
