Abstract

The utility model discloses a dispenser special for a solid acid rod and solves the problem that special dispensing equipment for the solid acid rod does not exist in actual application. The solid acid rod dispenser comprises an oil pipe, wherein the inner diameter of the oil pipe is equivalent to the diameter of the solid acid rod; two ends of the oil pipe are in threaded connection with ball valves; a supporting pipe is erected at a position which is 30-40cm away from the top end of the oil pipe; a pressure release valve is arranged on the supporting pipe; and two ends of the dispenser are provided with upper and lower valves and are connected with the mouth of a well through pup joint in a sealing mode. In addition, due to the arrangement of the pressure release valve, after pressure in the mouth of the well is released, the solid acid rod vertically falls in the well, the pressure dispensing safety is ensured, and a new way is developed for the actual application of the solid acid rod.

Description

Solid acid rod dispenser

Technical field

The utility model relates to and a kind of water injection well is carried out the scale remover dispenser that usefulness is handled in scale removal, and concrete is a kind of solid acid rod dispenser.

Background technology

The solid acid rod is a kind of novel scale remover; It is different from the liquid scale remover, and in use, the liquid scale remover can utilize the liquid conducting pipes of existing technology to be injected into the down-hole; And the solid acid rod can only be thrown in from well head; But because the water injection pressure of water injection well is very high, directly drives a well and throw in and to carry out, therefore need a kind of special on-the-spot delivery device.In view of above-mentioned state of arts, at first to guarantee when designing this delivery device and being connected of well head, secondly be to guarantee that on-the-spot band presses the safety of throwing in.

Summary of the invention

The purpose of the utility model provides the special-purpose dispenser of a kind of solid acid rod, has solved the actual application problem of solid acid rod, and this dispenser designs according to field working conditions, can guarantee the safety of throwing in pressing.

For realizing the foregoing invention purpose, the technical scheme that the application adopts is: solid acid rod dispenser comprises oil pipe; The diameter of the internal diameter of said oil pipe and solid acid rod is suitable; The two ends of the oil pipe ball valve that is threaded is set up arm in the position of the 30-40cm apart from the oil pipe top, and relief valve is set on the arm.

On the port of a preferred ball valve therein pipe nipple is installed.

The application's beneficial effect: the two ends of this dispenser are provided with lower valve; Be tightly connected through short circuit and well head; Be provided with relief valve in addition, after the pressure in the well head was laid down, the solid acid rod vertically fell in the well; Guaranteed the safety that the band pressure is thrown in, for road has been opened up in the practical application of solid acid rod.

Description of drawings

Fig. 1 is the structural representation of the application's dispenser.

Among the figure: oil pipe-1; Ball valve-2; Arm-3; Relief valve-4.

The specific embodiment

Below in conjunction with accompanying drawing the application is further described:

By shown in Figure 1: solid acid rod dispenser, comprise oil pipe 1, the diameter that the internal diameter of said oil pipe 1 and solid acid are excellent is suitable, and the two ends of oil pipe 1 ball valve 2 that is threaded setting up arm 3 apart from the position of oil pipe 1 top 30-40cm, is provided with relief valve 4 on the arm.

In the practical application; The solid acid rod is diameter of phi 42mm mostly; The pipe aperture that the application selects for use is Φ 50.4mm, and the internal diameter of oil pipe approaches the external diameter of solid acid rod, like this when the lower valve of switch dispenser; Be unlikely to make the acid rod to produce big inclination, make the acid rod keep plumbness to fall as much as possible.Certainly the specification of oil pipe can be adjusted according to the specification of solid acid rod, as long as ensure sour excellent vertical drop.

Ball valve port in a side during use installs pipe nipple and shaven head additional, and is connected and sealed with clip between the well head; Then the solid acid rod is encased in the oil pipe, closes and close after the valve, open lower valve; The solid acid rod vertically falls in the well, if borehole pressure is high, the solid acid rod can not free-falling; Can open relief valve, borehole pressure is laid down, solid acid rod nature will fall; After the input of acid rod finishes, close lower valve.

Claims

1. solid acid rod dispenser comprises oil pipe, it is characterized in that: the diameter that the internal diameter of said oil pipe and solid acid are excellent is suitable, and the two ends of the oil pipe ball valve that is threaded is set up arm in the position of the 30-40cm apart from the oil pipe top, and relief valve is set on the arm.

2. according to the said solid acid rod of claim 1 dispenser, it is characterized in that: on the port of a ball valve pipe nipple is installed therein.
