Test device for high-temperature and high-pressure inspection and evaluation of sand-preventing material

Abstract

The invention discloses a test device for high-temperature and high-pressure inspection and evaluation of a sand-preventing material in an oil-extraction engineering of an oil field. The device mainly comprises a steam supply system, a high-temperature integral test model, a high-temperature sample test model, a safety control system, a temperature control system, a back pressure control system, a cooling system, a recovery system, a data acquisition processing part, a sand-preventing material high-temperature and high-pressure test device, a high-temperature and high-pressure integral model and a high-temperature and high-pressure sample model, wherein well water is added into a water storage tank; calcium and magnesium ions are removed after water treatment by water treatment equipment;the water is fed into a steam boiler by using a high-pressure plunger pump; the high-temperature and high-pressure water steam of the boiler enters the high-temperature integral test model and the high-temperature sample test model through a ground pipe manifold; the water steam coming out of the other end of the model is cooled by a heat exchanger and discharged into the water storage tank; the temperatures and pressures of the systems are acquired by a temperature pressure sensor; acquired data is processed by a computer; and the computer controls the boiler, the pump and the like accordingto the data and automatically controls and protects the systems. The device solves the problem that sand-preventing simulation test can be performed only at the normal temperature in the prior art, and can be widely applied to sand-preventing test of the oil-extraction engineering of the oil field.

Description

Technical field: [0001] The invention relates to a high-temperature and high-pressure inspection, detection and evaluation test device for sand control materials used in oil production engineering tests in oil fields. Background technique: [0002] In order to improve the sand control effect of oil wells, major foreign companies and universities have established several sets of sand control simulation test devices. Taking the research on sand control of gravel packing in horizontal wells as an example, since the early 1980s, companies such as Schlumberger, Halliburton, Chevron, and Baker Hughes in the United States and Herrett-Water University in the United Kingdom have used large-scale solid-scale The horizontal well gravel packing simulation test device has carried out horizontal well gravel packing mechanism test research, established a horizontal well gravel packing mathematical model, carried out horizontal well gravel packing numerical simulation, parameter optimizatio...
