Embodiment Construction
[0018] refer to figure 1 and figure 2 , open the upper cover 16, take out the overall support, remove the primary collection container 11 and the sample holder 6, install the sample on the sample holder 6, fix the sample holder to the cover 5 of the inverted funnel, and tighten it with tools Thread, clamp sample 7 to prevent the experimental sand from falling from the edge gap of the sample. Screw the primary collection container onto the lower end of the specimen holder. The monolithic support is then placed into the heating furnace. Fix the upper cover and the furnace body with bolts.
[0019] Check whether the circuit is safe and start the furnace. Set the required heating temperature on the control panel of the temperature controller, and turn off the heating switch when the sample reaches the required temperature. Connect the air inlet 18 to the high-pressure gas cylinder, turn on the switch of the sand filling port 1, and add a certain amount of experimental sand i...

The utility model relates to an experimental device for sand-retaining performance of a high-temperature and high-pressure oil-gas sand control screen, which belongs to the field of filtration precision measurement. It is especially suitable for conducting screen sand-retaining performance experiments in different temperature and pressure environments, especially high temperature and high pressure environment conditions. The device consists of a sand filling port, a tee joint, a temperature measuring couple, a heating furnace, an inverted funnel cover, a sample fixture, a sample, a foot, a secondary collection container, an air outlet and a sand outlet, a primary collection container, and a heating sheet. , Experimental sand, air intake coil, bracket, upper cover, thermocouple two, and air inlet. The advantage of this device is that the sand-retaining performance of the sand-control screen under high temperature and high pressure can be obtained by using the experimental sand to pass through the sand-control screen under high temperature and high pressure, and the influence of temperature and high pressure on the sand-retaining performance of the screen can be obtained. It has important practical significance for clarifying the influence of high temperature and high pressure on sand retaining performance of sand control screen.
Description
technical field [0001] The invention belongs to the field of sand-retaining performance experiments of screen pipes, and relates to an experimental device for sand-retaining performance of sand-retaining screen pipes used in high-temperature and high-pressure oil and gas development. It is suitable for the study of the influence of high temperature and high pressure on the sand-retaining performance of the sand control screen, especially for the study of the influence of fluid temperature and pressure difference changes on the filtration accuracy of the screen. Background technique [0002] During the production process of oil and gas wells, the formation sand produced with fluids will cause great harm, which increases the cost of oil and gas production, and increases the difficulty of mining and management of oil and gas fields [1]. For sand-producing oil and gas reservoirs, sand control can prolong the production life of oil wells, protect surface production equipment, and...
