Dynamic parameter measurement nipple, energy-saving oil extraction system and method

Abstract

The invention provides a dynamic parameter measurement nipple, an energy-saving oil extraction system and method. The dynamic parameter measurement nipple comprises a nipple housing, a measuring cabin and an annular liquid flow channel, wherein two ends of the nipple housing are opened; the measuring cabin is sealed and fixed in the nipple housing via a supporting element; the measuring cabin is formed by a measuring cabin liquid inlet, a measuring cabin liquid outlet, a sensor and a measurement module; the annular liquid flow channel is arranged between the nipple housing and the measuring cabin; produced liquid of a production layer flows into the measuring cabin via the measuring cabin liquid inlet; the produced liquid flows into the annular liquid flow channel via the measuring cabin liquid outlet after passing through the sensor, the measuring module; the produced liquid flows out of the dynamic parameter measurement nipple via the openings; and produced liquid parameter of the production layer can be collected by the sensor and the measuring module. By the use of the dynamic parameter measurement nipple, the energy-saving oil extraction system and the method, oil well monitoring result precision and credibility are improved; long term dynamic monitoring and intelligent plugging functions can be achieved for the oil well; and energy waste can be avoided and effect of energy conservation and consumption reduction can be realized.

Description

Technical field [0001] The invention relates to the technical field of oil field development, in particular to a dynamic parameter measurement short section, energy-saving oil extraction system and method. Background technique [0002] In the process of oilfield exploitation, with the extension of development time, crude oil production will continue to decline. Since most oil wells are produced by water injection or polymer injection, the water cut of the oil production fluid is very high. The surface engineering facilities of the oilfield need to separate the large amount of water contained in the produced liquid, and then reinject it into the formation to increase the pressure of the formation, so as to drive out less and less oil in the formation. [0003] After long-term exploitation, the liquid produced in the formation is no longer a liquid with a homogeneous mixture of oil and water, that is, it does not belong to a depolarized distribution state, and the crude oil has no c...
