内蒙二连盆地北部重磁电资料综合解释预测含油有利区
|
摘要
针对中石化在内蒙二连盆地北部新区的勘探工作,收集、整理并连片处理了区内及外围航磁、重力与电法资料,在此基础上应用常规重磁数据处理技术和有特色的重磁异常优化滤波技术、航磁异常全梯度深度标定技术,结合其它物探资料和已知地质资料进行了综合解释并对成油远景进行了分析,提出了下一步勘探部署建议。进一步证明非地震方法在沉积盆地圈定和含油有利区带预测中具有良好的应用效果,也显示了老资料重新处理解释的不菲效益。
As a part of the exploration project for oil prospecting on the new area in the northern part of the Eren Basin, Inner Mongolia, aeromagnetic, gravity and electric data were collected and processed. For the gravity and magnetic data processing, the conventional method and specific optimal filtering and total gradient techniques were adopted. A prediction of prospective oil land in the area was then made based on the integrated interpretation of gravity and magnetic data combined with other geophysical data and geological information, with a suggestion for further oil exoploration put forward. It is indicated that non-seismic geophysical methods are effective for sedimentary basin outlining and oil & gas predicting.
