摘要
在渗吸模型的基础上,借鉴国内外油田开发经验并结合岩心实验,分析了流体在裂缝基质储层中各种力的作用,研究了低渗透裂缝油藏储层的渗吸特点,得出基质吸水压力、注水压力、注入量、注水周期等相关参数的确定方法,为渗吸法开发低渗透裂缝油藏的应用和推广提供了理论依据。
On the basis of imbibition model, taking development experiences home and aboard and core experiments into consideration, this paper analyzes various fluid forces in fracture matrix reservoirs and studies the imbibition characteristics of low permeable fracture then gets a new way to determine relevant parameters such as absorbing pressure, injection pressure, water injection rate and water injection cycle. All these provide the theoretical foundation for the promotion and application of imbibition oil recover-y in low permeable fracture reservoirs.
