摘要

在油田开发过程中，周期性扰动通过改变油的流动性和多孔介质的过滤能力参数来提高油井的流量和地层的最终采收率。在非均匀介质中，由于耗散和/或色散的存在，在井筒中产生的谐波振荡转变为具有周期性冲击锋面的锯齿波，这改变了相变的动力学，并可能导致液相中的空化。考虑到这种情况，将有可能充分预测相变的动态，并优化对石油生产过程的控制。

Singular Controls For Increasing Oil Recovery Of Natural Oil Deposits

n the process of developing oil fields, periodic disturbances are used to increase the flow rate of wells and the final oil recovery of formations by changing the mobility of oil and the filtration-capacity parameters of the porous medium. In an inhomogeneous medium, in the presence of dissipation and / or dispersion, harmonic oscillations created in the wellbores transform into sawtooth waves with periodic shock fronts, which change the dynamics of phase transitions and can lead to cavitation in liquid phases. Taking this circumstance into account will make it possible to adequately predict the dynamics of phase transitions and optimize the control of the oil production process.
