摘要

在天然地震的影响下,油井产量发生波动,使人们受到启示,从而引进了振动采油工艺技术。本文对振动增产的机理进行了探讨,指出振动增油机理在于加快地层中流体的流速;改变储集层内油、气、水的重新分布;改变岩石表面润湿性,有利于清除油层堵塞,提高渗透率。通过分析两个试验区的振动采油效果,总结出在不同扰动力、不同激振频率、不同振动周期下的增产效果和规律,对振动采油的实施具有一定的指导意义。

Abstract

Oil production fluctuation of well will take place due to effect of earthquake. Being enlighened from the above-mentioned fact, we developed vibration enhanced oil recovery technology.This paper discusses the mechanism of increase production of this technology,point out that the mechanism depends on it may increase flow speed,improve distribution of oil,gas and water in formation,change surface wettability of rock,help removal of formation plugging and enhance permeability. According to analysis of field application result in two test areas,this paper summarizes the increase production and laws in different perturbation force,different vibration frequency and different vibtation period,which have a guide significance for application of vibration oil enhanced recovery technology.
