最大限度地完整运用地震信息是提高反演动态解释有效性的主要方法,这些地震信息应当在钻井、地球物理测井和地震资料专业处理方法的基础上形成。综合速度谱预测技术就是专门进行处理和解释的方法之一,它建立在谱分解的基础上,而谱分解可以保障地震道和地球物理测井曲线的二维扫描。根据综合速度谱预测技术可以获得储层的比容、水力传导系数和产油率之间的关系。本文以季曼伯朝拉和西西伯利亚含油气省为例,在利用储层比容、水力传导系数和产油率关系的基础上,对区域内每口探井或一组探井的新远景区域的C1、C2、C1+C2储量进行了预测和评价,这样有利于提高地质勘探工作的有效性。
The most complete use of seismic information is the main method to improve the validity of dynamic interpretation of inversion. These seismic information should be formed on the basis of well drilling, geophysical well logging and seismic data processing methods. Synthetic velocity spectrum prediction is one of the methods that is specially processed and explained. It is based on spectral decomposition, which can guarantee the two-dimensional scanning of seismic traces and geophysical logs. The relationship between specific volume of reservoir, hydraulic conductivity and oil production rate can be obtained according to the integrated velocity spectrum prediction technique. Based on the relationship between specific volume of reservoir, coefficient of hydraulic conductivity and oil production rate, this paper takes the Qimangbu Chaocha and Western Siberia oil and gas provinces as an example. Based on the relationship between reservoir specific gravity, hydraulic conductivity and oil production rate, The reserves of C1, C2 and C1 + C2 have been predicted and evaluated, which will help to improve the effectiveness of geological exploration.
