| 摘 要： | 柴达木盆地的油气资源丰富,近年来在该区发现了大量异常显示,但是各种异常形成机理各不相同,存在较大多解性,使得该区油气储量探明率很低.根据柴达木盆地以往开展的常规非地震勘探的现状及效果,以磁测找油机理为基础,采用磁力资料化极、剩余磁力异常提取和磁力平剖图等处理手段,对三湖地区生物气藏磁异常进行分析研究,取得明显的异常显示效果.

| Abstract: | The Qaidam basin has rich oil and gas resources.However,anomalies found in recent years in the area are varied in formation mechanism and multi-explanations thus lead to low rate of proven oil reserves.Based on status and effects of the past conventional non-seismic exploration in Qaidam basin,this article mainly studies the magnetic anomalies of bio-gas reservoirs in Sanhu area by means of magnetic measurement oil-searching mechanism,polarization of the magnetic data,the residual magnetic anomaly extraction and processing tools of magnetic orthographic drawings,and achieves tangible results. |
