Visual model kettle for ultra-low gas permeation

Abstract

The invention relates to the technical field of oil exploitation, and discloses a visual model kettle for ultra-low gas permeation. The visual model kettle comprises a visual kettle body, wherein a gas inlet pipe is fixedly connected to one side of the visual kettle body. According to the visual model kettle for ultra-low gas permeation, needed rock is placed in the visual kettle body, two sets of one-way valves arranged on the gas inlet pipe are opened, one end of the gas inlet pipe is connected with an inert gas device, inert gas is sucked into the visual kettle body through work of a gas pump, the gas pressure intensity in the visual kettle body can be known through a pressure detector, and therefore oil in the rock can be effectively discharged out; and an oil pump is started, the oil is fed into an oil conveying pipe through a collecting pipe, impurities carried on the rock are effectively filtered out through a filtering plate in the collecting pipe, and therefore the purity of the oil is guaranteed. By means of the structure, the oil is effectively discharged out of the rock, and the oil extraction efficiency is improved; by arranging the model, the process of discharging the oil through the inert gas can be effectively simulated.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to a visual model kettle for ultra-low gas permeability. Background technique [0002] Gas lift recovery is a kind of oil recovery. Gas lift recovery is an oil recovery method that artificially presses gas into the bottom of the well so that crude oil can be extracted to the ground along the wellbore. This oil recovery method belongs to mechanical oil recovery, but the wellbore principle is different from that of automatic It is similar to spraying, and the equipment in the wellbore is simple. It is often used in deep offshore oil production wells, inclined wells, wells with more sand, water and gas in the wells, and wells with corrosive components. [0003] At present, with the continuous expansion of the application scale of gas lift oil recovery in oil fields at home and abroad, in order to meet the development and production needs of different oil fields, it is ne...

AI Technical Summary

Problems solved by technology

However, there is currently no device for simulating gas lift oil recovery, and during the process of collecting oil, no suitable monitoring device is installed to monitor oil transportation, which may lead to pipeline leakage or other problems in the pipeline during oil extraction. Gas mixing causes problems in oil collection and cannot be collected effectively
