摘要
复杂裂缝型新站油田加密后,为了保证加密井初期含水控制在指标内,从动态分析的角度,按照水驱油机理和注采平衡原理,劈分单井单层单方向的注入产出量,在传统水驱前缘计算方法的基础上,考虑单层裂缝发育程度的影响,确定注入水波及体积,从而计算出油井水淹半径,并结合静态解解,综合判断油井的水淹程度,为加密井射孔提供依据。应用改进的方法计算了20口井水驱前缘,取得了较好的开发效果。
In order to ensure the early water of infill well within the index after encryption in complex fracture oilfield of Xinzhan, according to the water and oil displacement mechanism and injection-production balance principle with the perspective of dynamic analysis, injection production was assigned to the single well monolayer in all directions. On the basis of the conventional calculation method for water flooding front, considering the influ- ence of the single fracture development degree, Injected water swept volume was determined, and the radius of water flooding was calculated. Combined with the static solving, water flooding degree of oil well was judged synthetically, which provided the ba- sis for inffll well perforation. Good development effect was ob- tained by applying this improved methods to calculate water drive front of twenty well.
