摘要
樊家地区沙三段地层为高青扇三角洲的前缘相沉积,发育了一系列互不连通的浊流砂体,浊流砂体在地震剖面上以弱能量、叠瓦状、短同相轴出现。利用合成记录、VSP、道积分剖面对浊流砂体进行标定和定量解释,求得砂体的厚度图和消除了火成岩影响的精细构造图。在此基础上,参考钻井、测井资料,对砂体的形态、分布及含油情况进行综合解释和油藏描述,预测了砂体的含油面积和地质储量。经钻井证实,该区的油藏描述是成功的。
The third member of the Shaheji formation in Fanjia area is the frontal sediments of the Gaoqing fan delta.It has many unconnected turbidite sand bodies, which appear as shingled weak short events in a seismic section.Both the isopach map and the exact structural map without igneous rock influence have been plotted successfully by correlating and quantitatively interpreting the turbidite sand bodies with the use of synthetic seismograms, VSP and trace integral section.Furthermore, Oil bearing area and geological reserve were predicted by comprehensively interpreting the shape, distribution and oil content of the turbidite sand bodies, and then making reservoir description, with referring to relevant drilling and logging data.Drilling has proved the reservoir description successful.
