【摘要】 平衡剖面不仅可以用于评价和检验地震解释剖面、分析盆地构造演化,还有助于分析油气的动态成藏过程。对哈萨克斯坦M盆地的主干地震剖面进行了平衡剖面恢复,分析了盆地的构造演化特征及构造发育对油气成藏的影响。研究结果表明,M盆地中新生代地质演化具有明显的阶段性,早、中侏罗世为盆地断陷伸展、沉积与沉降的主要时期,白垩纪主要为坳陷期。构造控制了盆地的油气成藏条件,两次构造抬升和两次深埋是造成油气成藏过程非连续性的主要因素。更多还原

【Abstract】 Balanced cross-section can be used not only to evaluate and test seismic interpretation profiles,analysis of tectonic evolution,but also can combine the oil and gas accumulation theory,truthfully reproduce the dynamic accumulation process of hydrocarbon.In this paper,we balanced one main seismic profile in M basin,Kazakhstan,and analyzed the characteristic of tectonic evolution and its effects to hydrocarbon accumulation.The results show that the evolution of the basin can be divided into five stages,in which the Early-Middle Jurassic period is the main stage for basin fracture extension,deposition and subsidence,and the Cretaceous period is the main stage for basin depression.Structure controlled the hydrocarbon accumulation conditions.Two tectonic uplifts and two deep buries are the main factors which resulted to the discontinuity of hydrocarbon accumulation process.更多还原
