摘要
针对我国目前振动法采油技术在实际应用中盲目性大、增产效果难以预料的状况 ,从理论上研究了振动场对原油渗流的影响 ,推导出了几种主要增产机理与地层渗透率和原油粘度间的关系式 ,并用实例检验了公式的合理性。从而使振动参数和增产效果间的关系趋于定量化 ,对指导生产有重要意义。
Aimed at the blindness in application and difficulty of forecasting the stimulation effect in using vibration production, this paper studies the effects of vibration field on crude oil seepage flow. The relational formula between a few stimulation mechanisms, formation permeability and crude oil viscosity is derived, and its reasonableness is verified by examples. So the relation between vibration parameters and stimulation effect becomes quantitative, which has a very important role in guiding production.
