摘 要: | 本文以西峰油田董志区长8油藏为例,运用数值模拟技术,研究了水平井组合方式及其井网形式。研究结果表明,水平井是提高特低渗油藏开发效果的有效途径。结合长庆特低渗储层吸水性能好的特点,认为采用直井注水,水平段走向垂直于储层最大主应力方位的水平井采油的井网组合开发效果最佳。

Abstract: | Combination mode and Well pattern of horizontal wells are studied in this paper, by application of numerical simulation technology, taking the Chang8 reservoir of Dongzhi district of Xifeng oilfield. Research results show the horizontal well is an effective approach to enhance the effect of extra-low permeability reservoir development. Well pattern combination of vertical well injection and horizontal well production with the horizontal interval trend perpendicular to the most main reservoir stress orientation is considered to have the best development result, in the light of characteristics of good water intake capacity of extra-low permeability reservoirs in Changqing oilfield. |
