Embodiment

[0009] In an embodiment, with reference to the drawings, the separator includes a separator main body 1 , a first liquid level gauge 2 , an inlet 7 , an outlet 6 , an exhaust port 8 , and a gas balancer 3 . Open a hole at the upper scale of the first liquid level gauge 2 of the separator main body 1, and communicate with the water bag 4, install the second liquid level gauge 5 on the top surface of the water bag 4, and the exhaust port on the top of the separator main body 1 It communicates with the first liquid level gauge 2 and the second liquid level gauge 5 through the gas balancer 3 . Control valves 9 are respectively installed on the connecting pipes of the gas balancer 3 and the first liquid level gauge 2 and the second liquid level gauge 5 .

[0010] The separator in the present invention is based on the original 600mm separator used in the oil field, and is modified according to the principle of a connecting device: a hole is opened at a distance of 720mm from the low...

Abstract

The invention relates to separator and measuring method for measuring water content of oil well. The measuring method is: (1) the liquid needed to be measured is poured into the separator, shuts off the balancing valve, and the liquid level of the separator is decreased to the lowest; (2) opens the balance valve, the liquid level upgrades, when the liquid level upgrades to the upper limit a of the oil glass tube, records the lifting height of the second liquidometer, and pours the liquid out of the separator; (3) pours liquid of another well into the separator, repeats above mentioned two steps, acquires the rising height of the second liquidometer; (4) works out the water content according to the water content formula of oil well. The method is simple, and the process is convenient, the measuring precise is upgraded greatly.

Description

1. Technical field: [0001] The invention relates to a device and a method for measuring water content, in particular to a separator and a method for measuring the water content of an oil well. 2. Background technology: [0002] At present, the water content of oil wells in various oilfields is generally obtained by manual sampling and testing in the early 1960s in Daqing Oilfield. Oil production workers take oil samples at the wellhead, and analysts use distillation to test. As oilfield development enters the middle and later stages, there is a large amount of free water in the produced fluid of most oil wells. Due to the heterogeneity of the fluid in the oil well pipeline, the samples obtained cannot truly reflect the composition of the liquid in the pipeline. There must be a large error in the moisture content data. According to research, this error can reach 20% - 30%, while the current separator includes a separator main body, a liquid level gauge, inlet, outlet, and ex...
