Abstract
The invention discloses an oil pumping tubular column for an oil well. The oil pumping tubular column for the oil well is characterized in that the lower end of a flexible coiled tubing (3) of which both ends are respectively provided with a flexible tubing joint (4) is connected with a rodless electric deep-well pump (5). The oil pumping tubular column disclosed by the invention is used for oil field pumping wells, and as the flexible coiled tubing (3) and the rodless electric deep-well pump (5) are adopted as a main body, operation that joints are connected or detached does not need to be performed during trip operation, and convenience is brought to underground construction; meanwhile, as equipment, such as a rod string and a pumping unit, is canceled, not only is the production cost reduced but also the consumption of electric energy can be reduced.
Description
Technical field: the present invention relates to a kind of oil field well instrument, especially for a kind of oil well oil-pumping tubing string of pumpingh well.
Background technology: before the present invention, the conventional oil pipe of the many employings in each oil field and common deep well pump are the pumping pipe string of main body, therefore need repeatedly carry out connecting or dismantle single operation when carrying out rountrip, making troubles to underground construction.
Summary of the invention: the object of the invention is: for oil field pumping well provides a kind of oil well oil-pumping tubing string, because this device adopts continuous-tube to substitute conventional oil pipe, adopt and replace common deep well pump without bar motor-operated well pump, thus connecting or dismantling single operation when carrying out rountrip without the need to repeatedly carrying out, bringing convenience to underground construction.
The object of the invention is to be realized by following measures: a kind of oil well oil-pumping tubing string, comprise flexible continuous pipe, without bar motor-operated well pump, flexible pipe joint, it is characterized in that the flexible continuous pipe lower end that two ends are all provided with flexible pipe joint is connected with without bar motor-operated well pump.
Object of the present invention can also be realized by following measures: the flexible continuous pipe of oil well oil-pumping tubing string can be and strengthens rubber coiled tubing, reinforced plastic coiled tubing, glass fiber reinforced plastic coiled tubing; Linear electric motors piston deep-well pump, electrical submersible centrifugal deep well pump, electronic without rod-type screw pump is can be without bar motor-operated well pump; Oil well oil-pumping tubing string also sleeve pipe anchor can be installed without on bar motor-operated well pump.
The present invention is used in oil field pumping well, owing to adopting flexible continuous pipe and being main body without bar motor-operated well pump, thus connect or dismantle single operation when rountrip without the need to repeatedly carrying out, bring convenience to underground construction, simultaneously also owing to eliminating the equipment such as rod string and oil pumper, not only reduce cost of production, the consumption of electric energy can also be reduced.
Accompanying drawing illustrates: Fig. 1 is the structural representation of oil well oil-pumping tubing string.
Detailed description of the invention: oil well oil-pumping tubing string is by flexible continuous pipe 3, forms without bar motor-operated well pump 5, flexible pipe joint 4, sleeve pipe anchor 6 etc.; Its flexible continuous pipe 3 can according to oil well situation selective enhancement rubber coiled tubing, reinforced plastic coiled tubing or glass fiber reinforced plastic coiled tubing; It can select linear electric motors piston deep-well pump, electrical submersible centrifugal deep well pump or electronic without rod-type screw pump according to oil well liquid-producing situation without bar motor-operated well pump 5; Flexible continuous pipe 3 lower end that its two ends are all provided with flexible pipe joint 4 is connected with without bar motor-operated well pump 5, can select mounting sleeve anchor 6 without on bar motor-operated well pump 5 according to its pump setting depth.
Operating principle and the using method of oil well oil-pumping tubing string are: first according to the length of the down-hole desired depth determination flexible continuous pipe 3 without bar motor-operated well pump 5, again by entering sleeve pipe anchor 6 under Ground Operation equipment is successively in down-hole casing 2, without bar motor-operated well pump 5 and the flexible continuous pipe 3 with flexible pipe joint 4, then the flexible pipe joint 4 of flexible continuous pipe 3 by its one end being connected with well head 1.Simultaneously under enter flexible continuous pipe 3 time also should enter external working cable according under on-the-spot reality, and itself and flexible continuous pipe 3 outer tube wall are fixed; Or adopt the mode burying working cable in flexible continuous pipe 3 tube wall underground, and make cable one end by its operational procedure and be connected without bar motor-operated well pump 5, the other end draws from well head 1; Oil pumping first should be pressurizeed from well head 1 before producing and sleeve pipe anchor 6 is stuck on sleeve pipe 2 inner tubal wall in flexible continuous pipe 3.Be adopt flexible continuous pipe 3 due to the present invention and be main body without bar motor-operated well pump 5, thus when rountrip without the need to repeatedly carrying out connecting or dismantling single operation, bring convenience to underground construction; Simultaneously also because the present invention when oil pumping is produced relies on sleeve pipe anchor 6 to bear whole gravity, thus alleviate the load of flexible continuous pipe 3, thus can ensure that it works reliably and with long-term.
