Problems solved by technology

When using this method, it is necessary to use a laser altimeter to measure the foam height. The cost of the instrument is high, the operation is difficult, and the volume of the PVT cylinder is small, and the amount of foam produced in the experiment is small, so it is not easy to measure

Abstract

The invention discloses a device and method for testing the foaming performance of a surfactant under high-temperature and high-pressure conditions, which are mainly used for solving the problem of lack of a device and method for effectively testing the foaming performance of the surfactant in the prior art. The invention is characterized in that: the device is formed by arranging a high-pressure, constant-speed and constant-pressure pump, a piston container and a reactor in a constant-temperature box; and the reactor is provided with a transparent observation window structure with an altitude scale. When the device is used, the surfactant and foaming gas are pumped into the reactor in sequence by using the high-pressure, constant-speed and constant-pressure pump, and a foam half-life period and a foam altitude are directly measured by using the altitude scale in the observing window structure after preset reaction pressure, temperature and ventilating time conditions are satisfied. The device and method have the characteristics of low production cost, easiness in operation, large amount of foams and capability of testing the foaming performance of the surfactant under any pressure condition, and have good popularization and application prospects.

Description

technical field [0001] The invention relates to a device for measuring the foaming performance of a surfactant, in particular to a device and a method capable of measuring the foaming performance of a surfactant under high temperature and high pressure conditions. Background technique [0002] At present, in the field of oilfield chemistry, the evaluation of the foaming performance of surfactants under high temperature and high pressure conditions is mainly evaluated from two aspects: foaming ability and stability. The parameters that characterize foaming ability and foam stability are mainly foaming height. h f and the foam half-life T. The methods for measuring the foaming performance of surfactants in the prior art are mainly divided into stirring method and fluid analysis method. Among them, the stirring method means that the experiment is carried out in a stainless steel high-temperature and high-pressure reactor with a glass observation window and a magnetic stirrin...
