地震属性应用中的不确定性
The uncertainties in seismic attribute application
【摘要】 地震属性在油气勘探开发中发挥着越来越大的作用。由于其应用属于求解地球物理反问题,在数据有限并存在误差时具有不确定性和非惟一性。根据地球物理反演理论,着重分析了地质条件、观测数据、预测方法和主观因素对地震属性可靠性的影响,指出了引起地震属性不确定性的基本原因,明确了地震属性的应用前提、应用条件和应用范围。
【Abstract】 The seismic attributes have been bringing into play more and more in petroleum exploration and development. The methods are uncertain when the data is limited and has errors because of its application is restricted to find the geophysical reverse solution. The impact from geology, observations, prediction methods and subjective knowledge on seismic attributes application are analyzed based on geophysical inversion theory.The fundamental causes which result in the uncertainties are pointed out. The application prerequisite and range of the seismic attribute are further defined.
【Key words】 seismic attribute; uncertainty; reverse solution; interference and error;
