波形差异反演方法及其在气藏描述中的应用

在油气藏开发中后期,如何利用的已有的勘探成果和丰富的油气藏知识,加深对勘探区域油气开发潜力的认识,为油气田的稳产高产服务,是摆在油气田中后期开发人员面前的难题.油气田开发的研究人员,利用现有的资料,开发出了很多方法,结合地震测井等资料为油气田的稳产高产做出了巨大的贡献.本文在分析了地震波在地质体中传播过程中能量变化,相应的产生了振幅变化的理论,利用三维地震数据,通过对三维地震数据解释层位对应的波形差异的分析,结合工区内的生产井和开发井的对应地层中的油气信息,进行反演得到地层的波形差异数据体,利用相应的绘图软件绘制二维平面图形,结合工区内的沉积相等地质信息对其数据体进行油藏解释,最终得到波形差异反演数据体,利用波形差异反演数据体进行油气藏的识别、描述和预测,为油气田的中后期开发服务.

The inverse of wave different and its application in the forecast of gas

The difficult how to utilize of those explored production and the abundant old information about oil and gas to serve the aim what is to increase the knowledge of the output oil and gas to the oil field should be faced to the developer in the middle of exploration in the oil field.Which technique can increase the knowledge of the output oil and gas with integrate of the information of seismic and well to be developed by many people.The variety of energy,which transmitted in the earth of seismic,is to be analyzed in this article.The swing of seismic is changed with the different of substance in the medium.We can forecast the information of oil and gas when we use this information combine with that old information of this oil field.
