扶余油田泉四段裂缝发育特征及其对开发的影响
Fracture Development Characteristics and Its Influence on Development in Q4 Member of Fuyu Oilfield
摘要
Abstract
In the process of water injection development, the water breakthrough of natural fracture has strong universality and directivity. Accurate identification of the occurrence of natural fracture, especially the fracture distribution characteristics of oil enrichment area, therefore, is the key to the improvement of water injection recovery for high water-content fractured low permeability oilfield. This paper makes full use of existing pressure coring and dynamic development data, systematically analyzes the distribution characteristics of natural fractures in the studied area, and studies the influence mechanism of fracture on water flooding development. The study results show that small size, high angle fractures with short extension are highly developed in Fuyu oilfield, with east-west fracture direction. Therefore the injected water will rapidly fill the east-west fractures, and water channeling will occur. This results in the water flooding and shut-in of oil wells in east-west direction, and the remaining oil is formed between east-west oil and water wells; the volume sweep efficiency of injected water in east-west direction is small, and the water flooding effect is poor.关键词
