Embodiment Construction

[0023] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0024] Such as figure 1 As shown, the crude oil pipeline water content analyzer of this embodiment includes: a sampling unit including an oil pumping device 11 and a sampling pipeline 12 connected between the oil pumping device 11 and the crude oil pipeline 2; a composite sensor including a radio frequency capacitive sensor, The radio frequency capacitive sensor is arranged on the sampling pipeline 12 .

[0025] Use the sampling unit to extract crude oil in the crude oil pipeline, and use the radio frequency capacitive sensor to detect the extracted crude oil. Since the state of the extracted crude oil is more stable than the crude oil in the crude oil pipeline, it is beneficial to use the rad...

Abstract

The present invention provides a crude oil pipeline water analyzer comprising a sampling unit and a composite sensor, the sampling unit includes an oil pumping means and a sampling pipe which is connected between the oil pumping means and a crude oil pipeline; the composite sensor includes a radio frequency capacitive sensor, and the radio frequency capacitive sensor is arranged on the sampling pipe. Crude oil is extracted from the crude oil pipeline by the sampling unit, the crude oil is detected by the radio frequency capacitive sensor, the extracted crude oil is more stable in state than crude oil in the crude oil pipeline, and detection of the crude oil by use of the radio frequency capacitive sensor can be facilitated.

Description

technical field [0001] The invention relates to the field of crude oil analysis equipment, in particular to a crude oil pipeline moisture analyzer. Background technique [0002] In recent years, with the continuous progress of various measurement methods, analysis techniques and calculation models, the digital detection of oilfield recovery efficiency has become an important research field. Especially for oil wells using thermal recovery technology, if the production fluid can be accurately measured on-line in phase separation, the data can be quickly fed back to the upstream steam injection system, and related downhole temperature and pressure measurement systems and Cooperate with the boiler outlet dryness measurement system to reasonably adjust the boiler steam injection parameters, so that a complete set of digital network can be built between the injection and production systems of the oil field, and the most reasonable crude oil recovery can be obtained under the minim...
