随着人们对油藏开发的认识程度不断加深,逐渐总结出了各类油藏的开发地质类型和开采特点,提出了各种开发地质分类方案。本文根据我国现已投入开发的油田,提出了二个对我国油藏的开发地质分类意见,分类以储层和原油性质为基础,因为考虑到阶相湖盆储层的特征不仅直接影响到油藏开发特点,而且在很大程度上影响到原油性质、油水分布等其他重要开发地质特征。油藏开发地质类型是以指导油藏合理开发为目的,直接为油藏开发服务的,有效地指导油田的挖潜和提高采收率。要提高油藏开发工作的科学性、预见性和效益性,必须对油藏的开发地质类型有很深入的认识,从而科学的指导油藏工程的顺利进行。
With the deepening of people’s understanding of reservoir development, the geological types and mining features of various types of reservoirs have been summarized. Various geological classification schemes for development have been put forward. Based on the oilfields now under development in our country, two opinions on the geological classification of the development of our country’s reservoirs are proposed. The classification is based on the properties of the reservoir and the crude oil. Considering that the characteristics of the reservoir in the step-wise lacustrine basin not only directly affect the oil Tibet development characteristics, but also to a large extent affect the nature of crude oil, oil and water distribution and other important geological features of development. The geological type of reservoir development is to guide the rational development of the reservoir for the purpose of serving the reservoir development directly and effectively guiding the potential of the oil field and enhancing the oil recovery. In order to improve the scientific, predictability and profitability of reservoir development, it is necessary to have a deep understanding of the geological types of reservoir development so as to guide the smooth progress of reservoir engineering.
