【摘要】 新华夏系第二沉降带华北沉降区受郯庐断裂中新生代应力方式及应力场的影响,广泛发育了不同级序旋扭构造体系,控制了不同级序复式油气聚集区带的形成分布。油气主要富集在内旋回层和撒开端,弧形断裂内侧和构造运动活跃期形成的低级序扭动构造中,对指导油气勘探开发有重要意义。更多还原

【Abstract】 With the effect of stress and stress field in Tanlu fault in Meso-Cenozoic,tectonic systems of various rotational shear structures are developed extensively in Huabei depression area in the second depression zone of new Cathaysian,which controls the generation and distribution of duplex hydrocarbon accumulation zones in different degrees.Oil and gas are concentrated in the inner cycle bed,divergent places,inner part of the arc faults and the lower-order twisting structures formed in tectonic movement active phase,which has important guiding significance in oil and gas exploration and development.更多还原
