双相介质油气检测技术在龙西——杏西地区含油性预测中的应用

Hydrocarbon detection based on two-phase medium for oil-bearing prediction in the Longxi-Xingxi area

松辽盆地龙西—杏西地区在萨尔图、葡萄花油层相继获得高产工业油流,具有巨大的勘探潜力。HA17井区地震资料品质较好,无切值、无截频现象,根据地下含油气时地震响应存在"低频共振、高频衰减"的现象,应用GeoEast系统双相介质油气检测技术预测有利含油区分布,结果与钻井一致,取得了良好的应用效果。

Great oil discoveries are achieved in Saertu and Putaohua oil formations in the Longxi-Xingxi area,which indicates a tremendous hydrocarbon potential. Based on high-quality seismic data newly acquired in this area, we conduct hydrocarbon prediction in the Well H17 area with some interpretation tools provided by GeoEast. When there is oil or gas underground, seismic response will show some phenomenon. We predict the favorable oil distribution with hydrocarbon detection based on twophase medium, submit a well drilling proposal. The drilling results show great consistence with our prediction, which proves the veracity of our prediction.
