Abstract
The utility model relates to a layering commingled oil production device, which belongs to a ground tool for an oil-field oil well. The utility model is composed of an upper connector (1), a regulating bolt (2), a nut (3), a spring (4), a working barrel (5), a spring press cover (6), a valve ball (7), a ball seat (8), a selective mining body (9), an outer working barrel (10) and a lower connecter (11). The ball, the vale ball, the spring press cover, the spring and the nut are orderly connected with the working barrel from right to left; a regulating bolt is connected with the nut; the working barrel is connected with the selective mining body; the outer working barrel is connected with the selective mining body; both ends of the outer working barrel are respectively connected with an upper connector and a lower connector. Crude oil of a lower layer can enter an annular (20) through a lower connector and a bridge type channel (21) and is merged with the crude oil of an upper layer; the crude oil can be pumped by an oil pump; the regulating bolt is used for regulating the opening pressure of a valve ball; the crude oil entering an oil pipe can maintain the same pressure system before the crude oil entering the oil well pump without mutual interference. Thereby, the layering combining pick goal can be realized. The utility model can simultaneously pick two layer oil through one oil pump; the investment is less.
Description
Technical field: the utility model belongs to the downhole tool that oilfield is used.
Background technology: run into some low permeability oil fields at present in field produces, the oil reservoir span is big, and the reserves of every layer of oil are low, can not in order to exploit this class oil well, generally adopt the method for double pump separate zone whole production or single-string multi-zone production separately as the oil well of a cover series of strata exploitation.The double pump separate zone whole production is to adopt packer to separate oil reservoir, is lowered to oil well pump respectively and recovers the oil in different oil reservoirs, so just needs to drop into a large amount of oil production equipments.Cause problems such as investment is big, deficiency in economic performance to enterprise, single-string multi-zone production can cause problems such as formation pressure system phase mutual interference.
Summary of the invention: reduce investment, increase economic benefit of enterprises in order to realize single pump separate zone whole production, reduce or eliminate between two oil reservoirs owing to span reaches the pressure disturbances that interlayer contradiction causes greatly greatly, bring into play two-layer production capacity effect to greatest extent, propose following technical scheme: the utility model is to be adopted body 9, outer working tube 10 and lower contact 11 and constituted by top connection 1, adjusting bolt 2, nut 3, spring 4, seating nipple 5, spring capping 6, valve ball 7, ball seat 8, branch.In seating nipple 5 from right to left successively connecting ball seat 8, valve ball 7, spring capping 6, spring 4, nut 3, on nut 3, connecting adjusting bolt 2, divide the left end of adopting body 9 to be connected on the right-hand member of seating nipple 5, outer working tube 10 is sleeved on the outside that branch is adopted body 9, is connecting top connection 1 and lower contact 11 respectively at the two ends of outer working tube 10.Only the utlity model has and just the extraction simultaneously of two-layer oil can be invested little, economic benefit advantages of higher with an oil well pump.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
The specific embodiment: present embodiment is by top connection 1, regulates bolt 2, and nut 3, spring 4, seating nipple 5, spring capping 6, valve ball 7, ball seat 8, branch are adopted body 9, outer working tube 10 and lower contact 11 and constituted.End at seating nipple 5 is provided with internal thread 14, is provided with external screw thread 15 at the other end of seating nipple 5, has oil outlet 12 at the middle part of seating nipple 5, and ball seat 8 is drum shape, has oil duct 19 in the centre of drum shape ball seat 8.Outer working tube 10 is cylindrical, end at outer working tube 10 is provided with external screw thread 17, the other end at outer working tube 10 is provided with internal thread 18, have fuel feed hole 13 at the middle part of outer working tube 10, on seating nipple 5 from right to left successively connecting ball seat 8, valve ball 7, spring capping 6, spring 4, nut 3 usefulness are threaded on the internal thread 14 on the seating nipple 5, regulate bolt 2 usefulness and are threaded on the nut 3, when turning when regulating bolt 2, the degree that compresses that can regulating spring 4.Divide the left end adopt body 9 with being threaded on the right-hand member external screw thread 15 of seating nipple 5, adopting at branch has oilhole 16 on the body 9, divides to adopt body 9 and be fixed on the outer working tube 10, divides the fuel feed hole 13 corresponding and connections on the oilhole 16 adopted on the body 9 and the outer working tube 10.Top connection 1 usefulness is threaded on the external screw thread 17 of outer working tube 10 left ends, and lower contact 11 usefulness are threaded on the internal thread 18 of outer working tube 10 right-hand members.When the oil field pumping well ordinary production, upper strata crude oil is through fuel feed hole 13, oilhole 16, divide and adopt body 9, behind the oil duct 19, back down valve ball 7, oil outlet on seating nipple 5 12 enters in the annular space 20 between seating nipple 5 and the outer working tube 10 again, lower floor's crude oil is through lower contact 11, divide the passageway bridge 21 adopt body 9 to enter annular space 20 between seating nipple 5 and the outer working tube 10, converge with the upper strata crude oil that enters annular space 20 again, enter oil pipe, extract out by oil well pump, be input in the petroleum pipeline through well head and go, by regulating the degree that compresses that bolt 2 comes regulating spring 4, reach the opening pressure of regulating valve ball 7, make two-layer pressure balance up and down, make the crude oil that enters in the oil pipe advance oil well pump and keep same pressure system before, do not disturb mutually, thus the purpose of realization separate zone whole production.
