摘要
根据力学和热力学分析,构造挤压应力导致流体增压是间接通过储集岩体应变实现的,流体压力增量与构造挤压体应变具有正比关系。统计表明,库车坳陷北部中生界圈闭的紧闭度及挤缩率与超压具有较高的正相关性。力学和构造地质学理论分析显示,圈闭的紧闭程度及挤缩率可以表达岩层体应变。所有这些分析证实,构造挤压作用是导致库车坳陷北部中生界储集层流体增压的主要因素之一。
Dynamics and thermodynamics analyses show that the incremental pore fluid pressure caused by tectonir: compressive stress is realized by bulk strain of reservoir indirectly, both of which assume relations of direct, ratio. The statistic analysis showed more intensive positive correlation between the tightness or compressive ratio and overpressures in Mesozoic traps in northern Kuqa depression. The analysis of dynamics and tectonic geology proved that the tightness and compressive ratio of traps could be used for description of the bulk strain. It is suggested that the tectonic compression is one of the main factors resulted in the incremental pore fluid pressure of Mesozoic reservoirs in northern Kuqa depression.
