Abstract

The invention discloses a device for simulating the oil-gas-water three-phase fluid variable mass flowing in a complex structural well shaft. The device comprises a simulation well shaft (1), a gas supply device (2) connected with the simulation well shaft (1), an oil supply device (3) and a water supply device. By utilizing the device, the flowing of a single phase fluid, a gas-liquid two-phase fluid, an oil-water two-phase fluid and an oil-gas-water three-phase fluid can be simulated with very wide simulation range, and the obtained experiment data is more accurate and good applicability is realized.

Description

technical field

[0001] The invention relates to an indoor experiment simulation device in the petroleum industry, in particular to a large-scale simulation device for variable mass flow of oil-gas-water three-phase fluid in a wellbore with a complex structure. Background technique

[0002] As a high-efficiency oil and gas recovery technology, complex structure wells are a new technology developed rapidly in the world oilfield development at the end of the 20th century. Using this technology can usually greatly improve the productivity and ultimate recovery of a single well, especially for Some special unconventional oil and gas reservoirs, such as low permeability, multiple fractures, and thin production layers, have more significant production benefits. At present, many countries in the world are using complex structure well technology to exploit oil and gas reservoirs. Although oil and gas resources can be effectively exploited by using complex structure wells, there are ...
