超稠油在油气资源中占有很大比例,其开发越来越受到重视。目前矩形超稠油油藏开采方式一般有两种:长水平井开采和短水平井-水平缝开采,但采用哪种方式开采更优尚无定论,本文将从产能方面进行探讨。本文的创新之处在于:(1)利用概念模型替代真实模型,解决了垂直面内渗透率不均的问题;(2)引入支撑剂数,绘制无因次采油指数和导流能力的图版,获取最大采油指数。
Ultra-heavy oil occupies a large proportion of oil and gas resources, and its development has drawn more and more attention. At present, rectangular extra-heavy oil reservoirs are generally exploited in two ways: long horizontal well and short horizontal well-horizontal seam. However, it is not clear whether this method is adopted. This article will discuss the production capacity. The innovation of this paper lies in: (1) Using the conceptual model instead of the real model to solve the problem of uneven permeability in the vertical plane; (2) Introducing the proppant number, plotting the dimensionless oil production index and diversion ability, Get the maximum oil recovery index.
