摘　　要：注水开发是长庆特低渗油藏的主要开发方式，随着生产的进行，含水上升成为影响产量的主要因素，正确认识储层含水上升规律，是制订有效技术政策的基础，在研究含水上升规律方面主要有图版法、水驱特征曲线法和流管法．通过对比几种方法的优劣，优选出童氏图版法，并针对长庆低渗透油藏的特点加以改进，使其更适应长庆低渗透油藏开发规律研究的需要。The water injection development is the major way of the development of extra-low permeability reser- voir in Changqing. As the production progresses,the cut rising to become the main factors affecting tile yield. Correct understanding of the law of reservoir water rise ,which is the basis for the formulation of effective policy. Plate Law waterflooding characteristic curve method and flow tube method in the study of the laws of cut rising main. By contrast the pros and cons of several methods,preferably out of the boy＇s Plate Law,and to improve the characteristics of of Changqing low permeability reservoir,to make it more to adapt to the needs of Changqing low-permeability reservoir development law.
