Description
Technical field
The utility model relates to oil recovery technique field, oil field, and the down-hole oil production control device of multiple zone separate-zone producer in particularly a kind of oil field development is a kind of oil production by layer controller.
Background technology
For giving full play to each oil reservoir potentiality, to the multiple zone commingled producing well, adopt the oil production by layer pump, realize two-layer or commingling production, improve single well productivity.
The oil production by layer pump is that the two-stage (two-speed) pump connected mode is made up, and separates two pay intervals with packer, and the feed pathway of each pump is respectively with the fluid extraction of two oil reservoirs, and the top oil pipe or on pump standing valve place converge the back extraction.There are following three aspect problems in the The field:
1, present oil production by layer pump can only realize that the branch of two-layer well adopts, for two-layer above can't realizing.
2, separate extracting pump be with two-stage (two-speed) pump by combining, cost height (more than 2.0 ten thousand yuan) because pump height degree is about 10m, the roping difficulty is transported regulation according to oil well pump, needs the vehicle roping with the lengthening compartment, with anti-bending damage.
3, need supporting special repair apparatus, the maintenance difficulty is big, cost of overhaul height.
The utility model content
The purpose of this utility model is: a kind of oil production by layer controller is provided, gets rid of pressure reduction interference between oil reservoir, substitute the separate extracting pump of The field, improve the commingling production well capacity.The pump housing length that overcomes the separate extracting pump existence is big, roping is difficult, the maintenance deficiency that difficulty is big, the cost of overhaul is high.
The technical solution adopted in the utility model is: the oil production by layer controller, mainly form by top connection, side-pocket mandrel, valve seat, plunger, compression spring, adjustment seat and lower contact, it is characterized in that: there is external screw thread the lower end in top connection, there is external screw thread upper end in lower contact, and side-pocket mandrel is threaded between top connection and the lower contact; Described side-pocket mandrel is the cylinder bodily form, two parallel cylindrical holes are arranged in side-pocket mandrel, and the center line of two parallel cylindrical holes is parallel with the side-pocket mandrel center line; First cylindrical hole passes through the hole as lower floor's liquid.There is internal thread the lower end of second cylindrical hole, be fixed with a spring pressure at the lower end of second cylindrical hole screw thread and adjust seat, on the top of adjusting seat the compression spring is arranged, a plunger is arranged at the top at the compression spring, and the diameter of plunger lower end is identical with the diameter of second cylindrical hole; The upper end of plunger is a cone shape; There is valve seat upper end at plunger, and valve seat is fixed on the upper end of second cylindrical hole; Valve seat is a cylindrical shape, and the end is arranged at the top of valve seat; Valve seat has transverse holes, and the valve seat transverse holes is communicated with inlet opening on the side-pocket mandrel wall; There is axial valve opening the lower end of valve seat, and plunger upper end cone is in the valve opening of valve seat lower end, and valve seat and plunger play the one way valve effect; Between two parallel cylindrical holes outage is arranged, the position of outage is relative with the compression spring.
The transverse holes of described valve seat is a slot.
The operating principle of summary oil production by layer controller.Consult Fig. 1.Plunger 4 is divided into two zones with oil sets annular space and oil pipe, when formation pressure greater than oil pipe internal pressure 0.1MPa, plunger 4 moves downward, reservoir fluid enters the inlet opening 9 on side-pocket mandrel 2 walls; Opened the outage 8 of plunger 4 sealings when plunger 4 moves downward, reservoir fluid enters first cylindrical hole of side-pocket mandrel 2, with the fluid collection of lower floor to, flow to oil well pump, be pumped down to ground.Otherwise, if the oil pipe internal pressure greater than formation pressure, the double action that plunger 4 is pressed in spring 5 and oil pipe moves upward, and closes the oil-feed system automatically, gets rid of between oil reservoir pressure reduction thus and disturbs.
The beneficial effects of the utility model: the utility model oil production by layer controller, can with packer, the supporting use of oil well pump, with packer each oil reservoir is separated, the oil production by layer controller relies on pressure reduction to promote plunger and moves back and forth, open oil inlet passage, form each oil reservoir oil inlet passage independently separately, drain into ground by oil well pump.Avoid each oil reservoir because of the difference that aspects such as pressure, reservoir properties, development degree exist, caused interlayer contradiction and interlayer interference, caused each oil reservoir potentiality not give full play to.
Description of drawings
Fig. 1 is the utility model oil production by layer controller architecture generalized section.
Among the figure, the 1-top connection, the 2-side-pocket mandrel, the 3-valve seat, the 4-plunger, 5-compresses spring, and 6-adjusts seat, 7-lower contact, 8-outage, 9-inlet opening.
