新沟嘴组油藏是江汉油田增储上产的主要潜力区,如何提高新沟嘴组油藏的开发效果也一直是广大油田工作者重点攻关的对象。分析总结了新沟嘴组油藏注水开发特征,并深入分析开发特征的形成原因,提出了新沟嘴组油藏剩余油分布有利区域,结合目前现状,认为注水调整是下步工作的重点,油井适时压裂是挖潜的主要途径,而酸化工艺在新沟嘴组的运用还有待研究。
The Xingouzui Formation reservoir is the main potential area where Jianghan oilfield increases production and reserves, and how to improve the development effect of the reservoir in Xingouzui Formation has also been the focus of the majority of oilfield workers. This paper analyzes and summarizes the development characteristics of the water injection in the Xindugui Formation reservoir and analyzes the formation reason of the development characteristics in depth and proposes the favorable area for the remaining oil distribution in the Xugouzui Formation. Considering the present situation, it is considered that the water injection adjustment is the focal point of the next step, Timely fracturing of oil wells is the main way to tap the potential, and the application of acidification process in Xingouzui Formation has yet to be studied.
