摘要:
渗透率各向异性在气藏的开发过程中起着不容忽视的作用。以长庆油田某气藏为例,结合渗透率各向异性的理论基础,探索了渗透率各向异性气藏井网调整方法。其具体做法是,首先通过坐标变换将现有各向异性井网转化为等价各向同性井网,对现有井网的适应性进行评价;然后根据区块储层物性,建立各向同性机理模型来优选各向同性最优井网;最后在各向同性井网设计结果的基础上通过坐标变换设计得到适合气藏各向异性的最优井网。

Abstract: Permeability anisotropy played a role which could not be ignored in the process of gas reservoir development. By taking a certain gas reservoir in Changqing Oilfield as an example, a well pattern adjustment method was studied based on the basic theory of permeability anisotropic reservoirs. First of all, the current well pattern into was transformed into an equivalent isotropic reservoir well pattern on the basis of coordinate transformation rules so as to evaluate the adaptability of the current well pattern. Secondly, an isotropic mechanical model was set up for target reservoir for well pattern choosing according to the reservoir physical properties in the block. Finally, based on the results of isotropic well pattern design, the optimized well pattern suitable for gas reservoir anisotropy is obtained from coordinate transformation.
