摘　　要：通过砂体厚度及物性分布、砂体属性预测及反演等方法对双城地区FI油层组进行有利储层预测。所得出的结果为:FI的3个油层组中,FI3油层组砂体较为发育,FI2油层组砂体最不发育,FI1油层组砂体呈条带状展布。3个油层组均属于低孔低渗储层,但FI3油层组砂体发育最好,埋深相对较浅,物性最好。根据均方根振幅属性得到分流河道发育区分布的范围。确定了波阻抗、电阻率、伽马为主要反演参数。通过孔隙度、平均孔隙半径、排驱压力和含油产状这4种参数划分两类有利储层,并对每一个油层组进行了分类预测。研究结果表明:王府凹陷中心区域的有利储层仍然可以作为后期的重要勘探领域。Through the sand body thickness and physical property distribution,seismic identification and attribute prediction methods,favorable reservoir prediction will be carried out for the FI oil layer group in Shuangcheng area.The results are as follows: Of the three FI reservoir groups,the sand body of FI3 reservoir is relatively developed.The sand body of FI2 reservoir group is the least developed,and the sand body of FI1 reservoir group is distributed in strip shape.The three reservoirs all belong to low porosity and low permeability reservoirs,but the FI3 reservoir has the best sand body development,relatively shallow burial depth and the best physical properties.According to RMS amplitude attribute,the distribution of distributary channel is obtained.Wave impedance,resistivity and gamma are the main inversion parameters.Two kinds of favorable reservoirs are divided by four parameters: porosity,average pore radius,displacement pressure and oil-bearing occurrence,and each oil layer group is classified and predicted.The results show that the favorable reservoirs in the central area of Wangfu Sag can be used as an important exploration area in the later stage.
