Abstract
An oil well separate production allocator comprises an upper joint 9, a sand control net 6, a main body 7 and the like, and is characterized in that an L-shaped liquid inlet hole 5 is processed on the main body 7, and a pressure regulating cap 1, a spring 2, a valve ball 3, a valve seat 4 and a rubber ring 8 are sequentially arranged at the upper part in the hole. The utility model discloses rational in infrastructure, convenient to use, reliable operation for among the oil pumping well layering oil recovery technology, accessible adjustment valve ball 3 opening pressure realizes pressure packing, therefore can avoid the interference of pressure difference between the layers, improves the oil well and divides the oil recovery technology effect.
Description
Technical field:
The utility model relates to a kind of oil field downhole tool, adopts production mandrel especially for a kind of oil well branch of pumpingh well.
Background technology:
Before the utility model, each oil field in pumpingh well oil production by layer technology more uses fixedly faucet type production mandrel, because this device does not possess pressure packing function, thereby can't avoid the bigger interlayer interference of pressure reduction, has influenced oil well and has divided the excavating technology effect.
Summary of the invention:
The purpose of this utility model is: adopt production mandrel for oil field pumping well oil production by layer technology provides a kind of oil well branch, because this device can be controlled the valve ball opening pressure by the adjustment spring and realize the pressure packing, thereby can avoid interlayer interference, improve oil well and divide the excavating technology effect.
The purpose of this utility model realizes by following measure: a kind of oil well branch is adopted production mandrel, comprise pressure regulation cap, spring, valve ball, valve seat, sand control screens, cushion rubber, top connection, and the upper end is connected with the fluid course that is processed with upper and lower perforation on top connection, the lower end outer wall in the threaded tubular main body of processing, on its outer wall sand control screens is installed, it is characterized in that also being processed with simultaneously on the main body " L " shape inlet opening, its hole internal upper part is equipped with pressure regulation cap, spring, valve ball, valve seat and cushion rubber successively.
The utility model is rational in infrastructure, easy to use, reliable operation, be used for pumpingh well oil production by layer technology, can control the valve ball opening pressure by the adjustment spring and realize the pressure packing, thereby can avoid the interference of interlayer pressure difference, improve oil well and divide the excavating technology effect.
Description of drawings:
Fig. 1 adopts the structural representation of production mandrel for the oil well branch.
The specific embodiment:
It is to be made of pressure regulation cap 1, spring 2, valve ball 3, valve seat 4, inlet opening 5, sand control screens 6, main body 7, cushion rubber 8, top connection 9 etc. that the oil well branch is adopted production mandrel, the upper end is connected with the fluid course that is processed with upper and lower perforation on top connection 9, the lower end outer wall in the threaded tubular main body 7 of processing, and sand control screens 6 is installed on its outer wall; Also be processed with " L " shape inlet opening 5 on the main body 7 simultaneously, its hole internal upper part is equipped with pressure regulation cap 1, spring 2, valve ball 3, valve seat 4 and cushion rubber 8 successively.
Operating principle and using method that the oil well branch is adopted production mandrel are: can adjust the pressure that valve ball 3 should be opened by pressure regulation cap 1, again it is connected with pumping pipe string with screw thread on the main body 7 lower end outer walls by top connection 9, and down to predetermined producing horizon position; Adopt in the process at branch, owing to be subjected to the restriction and the depressurization of valve ball 3 opening pressures, make the liquid stream of this producing horizon position only when reaching certain pressure, can enter pumping pipe string, also avoided simultaneously because of this producing horizon position because of hypertonia, the interlayer interference that may cause other producing horizon positions, thus guaranteed that each minute adopt the ordinary production of layer position.
