Abstract

The invention relates to the technical field of heat injection steam and thickened oil thermal recovery, in particular to a heat injection steam dryness testing device. The device comprises a condenser, wherein a steam injection pipeline is connected to a steam inlet of the condenser, a steam outlet of the condenser is connected with a steam discharge pipeline, a cold water inlet of the condenser is connected with a cooling water inlet pipeline, a hot water outlet of the condenser is connected with a cooling water outlet pipeline, and a flow control valve, a flowmeter, a thermometer and a pressure meter are arranged on each pipeline. By testing the physical property parameters of the inlet pipeline and outlet pipeline of the condenser, the dryness value of inlet heat injection steam is obtained through analysis and calculation. According to the heat injection steam dryness testing device and a dryness value calculating method, the state of steam in the steam injection process can be dynamically monitored in real time, the testing device is simple and compact in structure, online continuous measurement of dryness can be achieved, reliability and precision are high, the oil recovery ratio can be increased effectively, and the boiler tube explosion rate can be reduced effectively.

Description

technical field [0001] The invention relates to the technical field of hot steam injection and thermal recovery of heavy oil, and is mainly used for testing the dryness of hot steam injected into steam injection pipelines so as to improve oil reservoir recovery and reduce the probability of pipe burst, specifically hot steam dry Dryness test device and its dryness value calculation method. Background technique [0002] my country is rich in petroleum resources, but many oilfields contain large amounts of asphaltenes and colloids, and conventional oil recovery methods are difficult to continuously recover heavy oil with high viscosity and high density. At present, the steam huff and puff technology is mainly used to continuously inject high-temperature and high-pressure saturated steam from the wellhead into the oil well. After a period of soaking the well, the heat of the steam diffuses to the heavy oil reservoir, which makes the temperature of the heavy oil rise and the vis...
