【摘要】 由于AVO响应存在多解性,即不同的岩性组合和流体组合可以产生相似的AVO响应,该多解性使得AVO的应用受到限制。AVO流体反演技术是用来分析AVO响应并将这些结果与理论结果相比较,确定流体的性质从而降低多解性问题并提供油气存在的可能性到底有多大。首先介绍了该技术的原理及实现方法,然后结合某地区的叠前地震资料进行了详细说明,并对结果进行了分析,认为通过AVO流体反演技术可以较好地提高油气预测的精度。更多还原

【Abstract】 As there existed multi-interpretations of AVO,there were different combinations of lithologies and fluids could result in same AVO response,AVO technique was limited by the multi-interpretations.It was used to analyze AVO response and its result was contrasted with theoretical one to determine the fluid property for reducing the problem of multi-interpretations and providing the extent of possibility of oil and gas existence.The basic theory of AVO fluid inversion and application are introduced,it is denoted in detail in combination with pre-stacked seismic data a certain area and the result is analyzed,it is considered that this method can be used to improve the predicting accuracy of the oil and gas.更多还原
