Indoor Vibration Flooding Simulation Experimental Device and Experimental Method

Abstract

The present invention relates to an indoor vibration flooding simulation experimental device and an experimental method, wherein the upper half of the rock core, the electromagnetic vibrator and the lower half of the rock core of the indoor vibration flooding simulated experimental device are all placed in the experimental sleeve, and the electromagnetic vibrator is set Between the upper half core and the lower half core, a lower circular plate with holes is set between the electromagnetic vibrator and the lower half core, an upper circular plate with holes is set between the electromagnetic vibrator and the upper half core, and the core holder holds the experimental set The cylinder is clamped inside; the lower end cover is set on the support, and the shock absorber is set under the support; the upper circular plate with holes and the lower circular plate with holes are equipped with simulated oil passages and evenly distributed cylindrical holes, and the core is clamped The device is provided with a simulated oil inlet, and the simulated oil inlet is bifurcated to form two simulated oil branch channels, and the two simulated oil branch channels communicate with the simulated oil channel of the upper circular plate with holes and the simulated oil channel of the lower circular plate with holes respectively; The vibrator is connected to the computer. The invention can greatly enhance the effect of vibration flooding.

Description

technical field [0001] The invention relates to an indoor vibration simulation experiment using crude oil as a seepage medium. During the indoor simulation vibration test process, a technology for improving crude oil recovery is obtained, in particular to an indoor vibration flooding simulation experiment device and an experiment method. Background technique [0002] Petroleum is one of the main energy sources in our country. It is an extremely important issue to rationally develop oilfields and realize stable and high yields. With the exploitation of oil, the pressure of the formation gradually decreases, and the energy of the oil formation decreases accordingly. Therefore, the supply, consumption and conversion of the energy of the oil formation are the core issues of the rational development of oilfields. At present, the corresponding measures adopted by the oil field are to supplement the energy loss of the underground oil layer through formation water injection, acid s...
