Abstract

The invention discloses an experimental device and method for vibratory oil displacement by water flooding. The device comprises a three-dimensional vibration unit, a core holding unit, a confining pressure pump and an injection pump, wherein the core holding unit is fixed on the three-dimensional vibration unit and comprises an injection end, an outlet end and a confining pressure opening; the confining pressure pump is connected to the confining pressure opening; the injection pump is connected to the injection end; and the injection end, the outlet end and the confining pressure opening areprovided with stop valves. The experimental device has the advantages that a vibrating process of generating longitudinal waves and transverse waves by natural shaking can be simulated by the device,the effect is obvious if a vibration method is implemented under a state of water flooding to residual oil, oil is recovered jointly by a composite vibration method in the initial stage of water flooding, the water flooding effect can be improved effectively, and the raw oil recovery rate can be further increased.

Description

technical field [0001] The invention relates to the field of oil and gas field development experiments, and more specifically relates to an experimental device and an experimental method for water flooding and vibration flooding. Background technique [0002] Vibration oil recovery technology is the technology of using various forms of vibration to act on the oil layer to extract oil. This technology originated from the phenomenon of increased oil production in oil wells found in the natural earthquakes in the old Grozny oilfield of the former Soviet Union in the 1930s, and it was subsequently found all over the world. The seismic process will be beneficial to increase crude oil production. The former Soviet Union began to study the mechanism of acoustic oil recovery in the 1950s, conducted a large number of indoor and outdoor studies, conducted large-scale field tests in the 1960s, and developed high-power ultrasonic oil well treatment devices in the 1970s. The field appli...
