洪泽地区由于沉积的特点,储层横向变化快,油藏受构造、岩性、油源多因素控制。在对该区三维AVO属性体解释中,利用多元回归方法求取了横波曲线,分岩性和含油气性统计了纵、横渡、泊松比参数分布规律,建立了本区的含油砂岩的正演模型,从而降低了AVO解释的多解性。通过井-震结合对四种AVO属性数据体进行了标定,并确定了各属性体应用范围,进而进行了储层和含油气检测。实践表明,该方法能有效地利用AVO属性数据体进行储层预测及油气检测,具有一定的推广价值。 Due to the characteristics of sedimentation in Hongze area, the reservoir changes rapidly laterally and the reservoir is controlled by many factors such as structure, lithology and oil source. In the interpretation of the three-dimensional AVO attributes in this area, the multiple regression method was used to calculate the transverse wave curve, and the distribution rules of vertical, horizontal and Poisson’s ratio were calculated and classified according to lithology and hydrocarbon bearing. Model, thus reducing the multiplicity of AVO interpretation. The four AVO attribute data bodies were calibrated by well-seismic combination, and the scope of application of each attribute body was determined. Then the reservoir and oil-bearing gas detection were carried out. Practice shows that this method can effectively use AVO attribute data to predict reservoir and detect oil and gas, which has some promotion value.
