实验设计方法在稠油油藏水平井分类中的应用

Application of Experimental Design Methods in Horizontal Well Classification of Extra-heavy Oil Reservoir

利用水平井蒸汽吞吐开发超稠油油藏,制定合理的工作制度的前提是对水平井进行合理的分类。开发早期通过地质参数、设备参数等静态因素对水平井进行分类,随着开发的进行,发现这种方法分类的井不利于工作制度的制定。本文将实验设计方法和数值模拟结合,考虑开发动态的影响,为水平井的分类提出新方法。

Horizontal steam huff and puff is one of the primary technologies for extra-heavy oil reservoir development. And good classification of horizontal wells is important and significant to production well proration making. In the early stage of oilfield development, horizontal wells can be classified based on static parameters including geological parameters, engineer parameters etc. When the development goes to mid-stage, the proration must be improved to solve the problems emerged in processing. But it is not easy to adjust the proration by old classification system. In this article, a new method was put forward. This new classification method has considered effect of production performance, and combined with experiment design and numerical simulation.
