利用重磁资料研究Vøring盆地断裂构造与油气远景
Fault structure and the oil and gas prospect of the Vøring Basin using gravity and magnetic data
摘要
Abstract
The Vøring Basin,in the Norwegian midland near the sea has favorable geological conditions for hy-drocarbon accumulation.To gain a deeper understanding on the fault structure and hydrocarbon exploration poten-tial in the basin,available gravity and magnetic data have been analyzed systematically.The Varimax transforma-tion technique was applied to eliminate the influence of latitude changes on the magnetic data.Additionally,the edge detection technique for potential fields was utilized to delineate the edge of the local field in this area.By in-tegrating existing geological and geophysical knowledge,a systematic analysis on the gravity and magnetic anom-alies in the study area was conducted,and ultimately the fault structure features of the Vøring Basin were identi-fied and the outlining favorable areas for hydrocarbon exploration were defined.Result indicates that the second-ary faults in the Vøring Basin exhibit complex orientations,including mainly two sets of major faults in northeast and nearly north-south directions respectively.Additionally,there are other two sets of faults trending northwest and nearly east-west,and they often cut across the first two sets of faults.The basin is surrounded by four major boundary faults(F1～F4),which control the development of secondary structures in the area.Favorable hydrocar-bon exploration areas in the Vøring Basin were delineated,represented by high-amplitude anomalies with clear gradients in the second-order vertical derivative anomalies,as well as anomalous bands controlled by faults and their flanks,as evidenced on the gravity gradient map.关键词
