Abstract

The invention discloses a differential pressure type crude oil condensation point measuring device and method and belongs to the technical field of oil gas automatic metering. The device comprises a testing tube section, a temperature controlling system, a gas storage tank, pressure gauges, a valve and a matched pipeline, wherein the gas storage tank is connected with the testing tube section so as to provide a gas source and regulate the pressure in the testing tube section, the whole testing tube section is located in the temperature controlling system to regulate the temperature during testing, the inlet pressure gauge and the outlet pressure gauge are connected with the testing tube section to test the pressure change at an inlet and an outlet, and the crude oil condensation point is judged according to the pressure difference of the inlet and the outlet. The method uses the device to measure the condensation point. The device is simple in structure, convenient to operate and capable of accurately measuring the condensation point of crude oil with pressure, and the oil structure destruction degree of the method using the device during measuring is smaller than that of a traditional measuring method.

Description

technical field [0001] The invention belongs to the technical field of automatic measurement of oil and gas, and in particular relates to a device and method for measuring the solidification point of crude oil by pressure difference. Background technique [0002] In recent years, with the continuous and high-speed development of my country's economy, the domestic demand for crude oil has also continued to increase, and the development of crude oil pipelines has also been relatively rapid. Safe and efficient pipeline oil transportation can reduce the operating cost of the oil industry, save energy and reduce consumption. For crude oil pipelines, the freezing point of crude oil is an important parameter. The accuracy of its measurement is not only related to the energy saving and consumption reduction of petroleum product storage and transportation, but also an important basis for its flow safety. [0003] The freezing point of crude oil refers to the highest temperature at w...
