【摘要】 建立了萍乐坳陷西部地区的航测、遥感油气预测模型。通过航测、遥感构造解译和区域油气成藏背景分析,指出该地区具有中小型油气藏成藏的构造条件。圈出了常指示油气圈闭构造的航磁局部构造异常和遥感环形构造,并提取了与油气微渗漏直接相关的微磁异常、航空放射性低铀异常、低钾异常和热异常,据此预测出三片油气成藏有利区。更多还原

【Abstract】 At first, a forecast model has been set up in order to evaluating the prospection potential of oil and gas resource with airborne survey and remote sensing data in the west of Pingle depression area Then, based on the analysis of regional tectonic features and the interpretation of airborne survey and remote sensing data, it is concluded that there are tectonic conditions helpful to form middle or smallsized oil and gas fields in this area Meanwhile,some local tectonics often indicating the information of oil and gas traps have been interpretted according to anomalies of aeromagnetic and cycle image The anomalies,which are immediately associated with oil and gas microseepage,have been extracted at the same time,for example,micromagnetic,lowuranium, lowpotassium, thermal anomalies Finally,Three favorable target areas have been proposed for the exploration of oil and gas reservoirs in the depression areas by mixing these anomalies information together更多还原
