不同条件下的注采井关调实验及数值模拟研究
Experimental and Numerical Simulation Study on Shut-In or Adjustment of Injection Production Wells under Different Injection Production Conditions
摘要
Abstract
This article conducts research on the injection production well patterns under different injection production conditions through two methods:physical simulation and numerical simulation.On the core scale,a reservoir physical simulation model was prepared based on similarity criteria.It was found that the higher the permeability of the physical model was,the lower the overall pressure value was and the smaller the average pressure drop after shutdown.As the viscosity of crude oil increases,the overall pressure of the model increases,and the reduction in pressure during adjustment becomes more pronounced.As the decrease in flow rate increases,the decrease in pressure regulation significantly increases.According to the numerical simulation results,due to the obstruction of the fault,there is no connectivity on both sides,resulting in different energy replenishment on both sides.As the mining progresses,the pressure difference decreases from 0.35 MPa in the initial stage to around 0.15 MPa.When both sides of the fault of the adjustment well are one injection and two extractions,the pressure difference between the two sides of the fault exists with the extension of the development time,but converges again in the late production period.While both sides of the fault of the adjustment well are one injection and two extractions and one injection and four extractions,the difference between the two sides of the fault pressure system increases with the extension of the development time.The research of this paper is of great significance to drilling of adjustment wells in the"Double High"oilfield.关键词
