摘要
通过对松辽盆地南部近 2 0年化探资料的综合研究 ,概述了该区的油气微渗漏与化探异常成因、地表化探主要影响因素、化探方法指标有效性、异常信息提取技术及化探异常模式 ,总结出适合于该区的有效油气化探方法系列以及一套干扰因素的排除、异常信息提取及化探异常解释评价技术。
Based on an integrated study of geochemical data obtained in southern Songliao basin in the past 20 years, this paper has given a rough description of the oil and gas micropercolation and origin of geochemical anomalies in this area, the main factors affecting surface geochemical exploration, the effectiveness of geochemical indices, the technique for extracting anomaly information, and the model of geochemical anomalies, and summed up the effective oil and gas geochemical technical series suitable for this area, and a suite of techniques for elimination of interference, extraction of anomaly information and interpreation and appraisal of geochemical anomalies.
