摘要: 在大套凝灰质砂砾岩、砂岩中寻找渗透性砂岩,用基于声波反演的储层预测方法,效果很不理想。改用以孔隙度为基准的反演方法,提高了储层预测的精度。同时利用属性分析的方法,识别优质储层,最终预测有利砂体2个。其中之一试油,获低产油流,使本已无望老井重又获得新生,为具有相似地质条件的其他地区的储层预测提供了借鉴。

Abstract: The inversion method of reservoir prediction, based on acoustic wave (AC), has been applied to find permeable sandstone in tuffaceous conglomerate and sandstone , and its predicting result is not ideal. Being used the inversion method based on porosity of reservoir, the prediction precision has then been increased. Meanwhile, the analysismethod of attribute property is also used to identify high quality reservoir ,as a result, two favorable sand bodies has been predicted, one of them has low-production oil flow after oiltesting, which makesmature oil-producing wells in this area revivify .The method can be used in reservoir predicting in other regions with similar geological condition .
