济阳坳陷孤西负反转断层形成演化定量研究及其油气地质意义
|
摘要
以高精度三维地震资料和钻井资料为基础,对研究区断裂构造进行精细解释,确定孤西断层为"薄底型"的、且表现为北段缓而南段陡、并向西倾的负反转构造;通过回剥技术和平衡剖面等定量分析技术对垂直穿越孤西断层的典型地震剖面研究揭示,孤西断层在J3-K1时期断层性质发生改变,由逆断层反转变为正断层,且在印支、J3-K1和Ek-Es4时期剖面拉伸率分别为-4%,17.2%和18.5%;沿孤西断层走向方向不同位置计算其断层活动速率表明该断层整体经历了负反转运动。以上述分析为基础,论文从烃源岩、圈闭、储集岩和油气运移角度,探讨了孤西负反转断层在孤岛潜山油气成藏方面的重要意义。
Based on the high resolution 3D seismic and well drilling data,the thin-bottom type of Guxi negative inversion fault is distinguished by analysis and interpretation of geological structures in study area,and the differences between northern and southern segment of the fault are recognized,and the dip angle of geometric northern segment is gentler than the one of the southern segment.By the method of balanced section,a geological section across the Guxi Fault was analyzed in details.The results indicate that properties of Guxi Fault are changed from reverse fault to normal fault during the period of J3-K1.Backstripping and balanced sections show the stretch ratio of Indosinian periods,J3-K1 and Ek-Es4 are-4%,17.2% and 18.5%,respectively;Along different locations of northern section of Guxi fault,fault activity rates reveal the fault wholly experienced inversion.Moreover,the relationship between Guxi negative inversion fault and its significance of hydrocarbon accumulation in Gudao buried hill are discussed including source rocks,traps,reservoir,and migration of oil and gas.
