伴随我国油田开发步伐的加快,对开发新技术的开发与应用提出了更高的要求。以安塞油田为例,有储层渗透率低特征,建立压力驱替系统极为困难,且受微裂缝发育影响,有平面水驱不均表现,开发中所应用的侧向采油井波及范围有限,致使低压低产情况出现。此时,便可考虑做井网调整优化工作,为油田开发提供技术保障。本文将对安塞油田地质规律与剩余油分布规律、安塞油田井网调整历程与效果以及安塞油田井网调整优化方式进行探析。
With the acceleration of the development of China’s oilfields, higher requirements are put forward for the development and application of new technologies for development. Taking Ansai Oilfield as an example, it has the characteristics of low reservoir permeability and it is extremely difficult to establish a pressure-displacement system. Due to the development of microcracks, there is uneven water flooding. The range of lateral oil wells used in development is limited , Resulting in low pressure and low yield situation. At this point, we can consider to do the well network adjustment and optimization work, to provide technical support for the development of oil fields. This article will analyze the Geological Law of Ansai Oilfield and the remaining oil distribution law, Ansai well field adjustment process and effect of well and Ansai Oilfield well pattern to optimize the analysis.
