Conflicting or cannot achieve when, will be understood that the combination of this technical solution is not present, also not the present invention claims protection model
Within enclosing.
Please also refer to Fig. 1-2, the present invention proposes a kind of submersible electric pump and gas lift valve geared power structure A in fact, described
Submersible electric pump includes with gas lift valve geared power structure A：Gaslift valve gear 02, underground submersible pump apparatus 01, ground installation (figure
In do not indicate), oil pipe 03, cable 05 and detection device 06；The detection device 06 and the underground submersible pump apparatus 01 are equal
It is electrically connected by the cable 05 with the ground installation；The oil pipe 03 be connected to the underground submersible pump apparatus 01 with it is described
Ground installation simultaneously runs through the gaslift valve gear 02.
Further, the underground submersible pump apparatus 01 includes：Circulating pump 11, protector 12 and submersible motor 13, institute
Circulating pump 11, protector 12 and submersible motor 13 is stated sequentially to connect from top to bottom；Diversion pipe 14,14 one end of diversion pipe connection
In the circulating pump 11, the other end extends to the bottom of the submersible motor 13.
In the present embodiment, detection device 06 monitors the gas-oil ratio of well liquid in oil well D, and monitoring signals are passed by cable 05
It is sent to ground installation, ground installation calculates analysis gaslift valve gear 02 by the gas-oil ratio of the well liquid of each section in analysis oil well D
The suitable position that should be placed；Underground submersible pump apparatus 01 is connect with gaslift valve gear 02 by oil pipe 03, and gas lift valve fills
It sets 02 to be connected to ground installation also by oil pipe 03, when gaslift valve gear 02 does not work and the work of underground submersible pump apparatus 01
When, gaslift valve gear 02 functions as oil pipe, and underground submersible pump apparatus 01 is connected to ground installation.Gaslift valve gear
It is determined whether 02 work by the gas-oil ratio of well liquid in oil well D, when the well liquid gas-oil ratio of 02 present position of gaslift valve gear is more than
When setting value, gaslift valve gear 02 enters working condition, when the well liquid gas-oil ratio of 02 present position of gaslift valve gear is lower than setting
When value, gaslift valve gear 02 is in off working state, it will be understood that the setting value might not be certain certain value, can also
Think a certain preset ratio range.
When the submersible electric pump and gas lift valve geared power structure A are used for natural gas extraction, due to gas hydrates well
Gas content is larger in liquid, and traditional centrifugal submersible electric pump easily causes gas lock, cavitation erosion when being pumped into the biggish well liquid of air content,
It causes submersible electric pump idle running, can not take out the phenomenon that well liquid, so that well liquid unsmooth flowing in oil well D, and further result in latent oil electricity
Machine can not radiate, to cause to damage to the work package of submersible electric pump, influence the service life of submersible electric pump.The present invention provides
Submersible electric pump and gas lift valve geared power structure A can be realized gaslift and liquid and lift two kinds of oil production methods, when gas contains in well liquid
When measuring higher, underground submersible pump apparatus 01 stops working, then is switched to the work of gaslift valve gear 02, avoids underground latent oil
Electric pump device 01 forms gas lock, cavitation because being pumped into high gas-oil ratio (HGOR) well liquid, realizes gaslift valve gear 02 and underground submersible electric pump
01 a preparation and a use of device, associated working, extends the service life of submersible electric pump.
As a kind of deformation, the gaslift valve gear 02 can also enter work shape with underground submersible pump apparatus 01 simultaneously
State realizes that gaslift is lifted two kinds of oil production methods with liquid and carried out jointly.
