Sand blocking performance experiment device for oil gas sand control screen pipe at high temperature and high pressure

Abstract

The invention provides a sand blocking performance experiment device for an oil gas sand control screen pipe at a high temperature and a high pressure and belongs to the field of filtration precision measurement. The sand blocking performance experiment device for the oil gas sand control screen pipe at the high-temperature and the high pressure is particularly suitable for conducting a sand blocking performance experiment for a screen pipe at various temperatures and various pressure environments, particularly in high-temperature and high-pressure environmental conditions. The sand blocking performance experiment device for the oil gas sand control screen pipe at the high temperature and high pressure comprises a sand addition opening, a three-way connector, a temperature measuring galvanic couple I, a heating furnace, an inverted funnel seal cover, a sample fixture, a sample, a support leg, a secondary collection container, an air and sand outlet, a primary collection container, a heating sheet, experiment sand, an air inlet coil pipe, a bracket, an upper cover, a temperature measuring galvanic coupling II and an air inlet. The sand blocking performance experiment device for the oil gas sand control screen pipe at the high temperature and high pressure has the following advantages: through the experiment that under the high-temperature and high-pressure condition, the proportion of the experiment sand to pass through the sand control screen pipe is tested, the sand blocking performance of the sand control screen pipe under the high-temperature and the high-pressure conditions can be obtained; the influences of high temperature and high pressure to the sand blocking performance of the sand control screen pipe can be obtained. The sand blocking performance experiment device for the oil gas sand control screen pipe at the high temperature and high pressure has practical significance for clarifying the influences of high temperature and high pressure to the sand blocking performance of the sand control screen pipe.

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] For sand producing oil and gas reservoirs, sand control is an indispensable part of oil and gas reservoir exploitation, and plays an important role in the stable exploitation of crude oil. The mechanical sand control method is a sand control method commonly used in oil fields at home and abroad at present, and about 80% of sand control oil and gas wells in foreign countries adopt this san...
