Abstract

FIELD: testing technology. SUBSTANCE: method consists in pumping liquid out of accumulating reservoir 1 and delivery of this liquid by means of pump 3 or 4, ejection of gas by means of jet apparatus 6, supply of it to delivery line and then to inlet of well condition simulator 5 by dispersed gas-and-liquid mixture thus formed followed by separation and return of liquid to accumulating reservoir 1; method also includes smooth control of flow rates and pressures; in course of tests, construction of flow section of jet apparatus is changed discretely to extend range of operational modes; flow rates of gas and liquid are changed smoothly from zero to maximum throughput capacity of jet apparatus by each phase respectively. To extend range of gas content from 0 to 100 percent, gas is forced into flow by means of compressor 8; to make testing conditions more realistic, use is made of simulator 5; angle of its deviation from vertical is changed from 0 to 135 deg. During tests, foaming properties and viscosity of working fluid are regulated as well. EFFECT: tests of submersible pumps, gas separators and electric motors of different arrangement.

Использование: для испытаний гидравлических машин и электродвигателей к ним. Сущность изобретения: в предложенном способе, включающем откачку жидкости из накопительной емкости, нагнетание ее насосом 3 или 4, эжектирование газа струйным аппаратом 6, подачу в нагнетательную линию, а затем на вход блока моделирования внутрискважинных условий 5 образующейся дисперсной газожидкостной смеси, ее последующую сепарацию, поступление жидкости обратно в накопительную емкость 1, плавное регулирование расходов и давлений, для расширения спектра режимов работы в процессе испытаний дискретно изменяют конструкцию проточной части струйного аппарата, причем расходы газа и жидкости плавно изменяют от нуля до максимальной пропускной способности струйного аппарата по каждой фазе соответственно. Для расширения диапазона газосодержаний от 0 до 100% в рабочий поток нагнетают газ компрессором 8, а для приближения условий испытаний к реальным используют блок моделирования внутрискважинных условий 5, причем угол его отклонения от вертикали изменяют от 0 до 135o. При испытаниях регулируют пенообразующие свойства и вязкость циркулирующего объема рабочей жидкости. Способ позволяет осуществлять испытания погружных насосов, газосепараторов к погружным насосам и электродвигателей к ним, струйных аппаратов, а также различных компоновок их совместной работы и может быть использовано для получения рабочих характеристик перечисленного оборудования, в частности для добычи нефти.

Usage: for testing hydraulic machines and electric motors for them. The inventive method, including pumping liquid from a storage tank, pumping it with a pump 3 or 4, ejecting gas with a jet apparatus 6, supplying it to the injection line, and then to the input of the downhole modeling block 5 of the resulting dispersed gas-liquid mixture, its subsequent separation, liquid flow back to storage tank 1, smooth regulation of flow rates and pressures, to expand the range of operating modes during the tests, the design of the flowing hour is discretely changed and an ink jet apparatus, wherein the gas and liquid costs smoothly varied from zero to the maximum capacity of the jet device for each phase respectively. To expand the gas content range from 0 to 100%, gas is pumped into the working stream by compressor 8, and to approximate the test conditions to the real ones, the downhole conditions modeling block 5 is used, and the angle of its deviation from the vertical is changed from 0 to 135 o . During testing, the foaming properties and viscosity of the circulating volume of the working fluid are regulated. The method allows testing submersible pumps, gas separators for submersible pumps and electric motors for them, jet devices, as well as various arrangements for their joint work and can be used to obtain the performance characteristics of the above equipment, in particular for oil production.
