摘要
W地区珠海组储层砂岩内部物性、含油气性变化快,开展储层物性预测尤为重要。叠前地震同步反演方法是利用不同炮检距道集数据和纵波、横波、密度等测井数据的反演方法,可同时反演得到储层岩性、物性相关的多种参数,用于综合判别储层物性及含油气性。将叠前地震同步反演方法应用于W地区珠海组储层的物性及含油气性预测中,利用获得的P波阻抗、S波阻抗及密度等地震特征参数对珠海组储层进行了综合判别,并对珠海组储层品质作了评价,优选出有利优质储层及其分布范围,并被钻探证实。
It is important to predict the physical properties of reservoirs in W area, due to the rapid varying of the physical and oil-bearing properties in Zhuhai Formation of this area. Pre-stack seismic inversion is a method of inversion based on the logging data, including various offset trace gathers, P and S waves and density. In this method, people can simultaneously obtain parameters related to lithological and physical properties of reservoirs. This can he helpful in comprehensively iudging the physical and oil-bearing properties of reservoirs. This study contains two steps mainly. The first step is to use this technology to predict the physical and oil-bearing properties of the reservoirs in Zhuhai Formation of W area. The second step is to discriminate the reservoirs of Zhuhai Formation based on the obtained seismic parameters, including P wave impedance, S wave impedance and density. Then, this study evaluates the quality of the reservoirs and identify some optimal parts and distribution of them which are verified by drilling data. Eventually, pre-stack simultaneous in version used in this study provides the technological support to the exploration of oil-bearing reservoirs in Zhuhai Formation in W area.
