Abstract

The invention provides a simulation evaluation device. An annular space formed between an outer cylinder and a screen pipe is filled with fillers of different particle sizes, and pressure of an oil gas outlet is adjusted to preset pressure through an outlet pressure control device to simulate wellhead pressure. Oil gas is transported to the outer cylinder at the preset flow rate by an oil supply device, then the oil gas flows through the fillers and enters the screen pipe through a screen hole of the screen pipe, the oil gas flows out from the outlet pressure control device under the effect ofpressure difference, the oil production rate of the fillers of different particle sizes is measured by an inlet oil gas measuring device and an outlet oil gas measuring device, the influence of the particle size of gravel in sand producing wells on the productivity of an oil gas well is evaluated, the situation that optimization and modification are carried out on oil extraction equipment when the particle size of the gravel produced by oil well sand production is in an appropriate range is avoided, the unnecessary oil production process is simplified, oil production efficiency is improved, oil production cost is saved, and an important basis is provided for the development and treatment of a sand production well.

Description

technical field [0001] The invention relates to the technical field of petroleum development, in particular to a simulation evaluation device. Background technique [0002] Sand production refers to the phenomenon that during the production process of oil and gas wells, due to excessive production pressure difference and rock cement transportation in sandstone oil and gas layers, formation sand flows into the wellbore, blocking oil and gas channels, and causing oil and gas wells to stop production. [0003] At present, in order to prevent oil well sand from clogging oil and gas passages and affecting the productivity of oil and gas wells, the sand control string in the oil production string is generally optimized so that the sand control string can effectively filter sand and gravel, such as sand control The pore size of the screen in the pipe string and the distribution of the screen holes are optimized; or sand removal equipment such as a hydrocyclone is installed in the w...
