Abstract
Disclosed is a novel striking oil draining apparatus which is a device in oil well production. The oil draining apparatus overcomes drawbacks of other technologies and is formed by connecting an oil draining apparatus body and hollow pins welded inside symmetrical axial holes of the oil draining apparatus body, and fragile grooves are arranged on the hollow pins. The working principle of the novel striking oil draining apparatus includes that the apparatus is mounted between an oil well pump and a fixing valve, when a pipe post is lifted out, an oil pumping rod is placed inside an oil pipe to break the hollow pins, and liquids inside the oil pipe leaks into the oil pipe from a broken hole. The apparatus has the advantages that the liquid inside a pipe post leaks into an oil well when the pipe post is lifted out, thereby not polluting ground.
Description
One, technical field: the utility model relates to a kind of device in the oil well production, especially a kind of new bump bleeder.
Two, background technology: present eccentric type bump bleeder, its structures shape it following shortcoming is arranged: 1, area of passage is little, and oil flow resistance is big; 2, adopt the seal with elastometic washer of " O " type, under the effect of bottom hole temperature (BHT) and oil-water media, " O " type rubber ring is easily aging, thereby loses sealing effectiveness; 3, be subjected to force unbalance, it is bigger to be subjected to hydraulic shock in aspiration procedure; 4, eccentric orfice changes oily flow path direction, increases oil flow resistance.5, after bleeder is opened, have only a draining hole draining, might be stopped up by bigger particle.
Three, summary of the invention: the purpose of this utility model provides a kind of new bump bleeder that does not pollute ground, it has overcome the shortcoming that other technology exists, the purpose of this utility model is to realize like this, it is to be formed by connecting by bleeder main body and hollow pin, the hollow pin is welded in the radial hole of bleeder main body symmetry, and easy fault trough is arranged on the hollow pin.
Operating principle: this device is installed between oil well pump and the standing valve, during lift pipe string, drops into a sucker rod in the oil pipe and the hollow mortise pin is pounded disconnected, and the liquid in the oil pipe leaks into oil pipe from pounding in the disconnected hole.
Meaning of the present utility model is when tripping out tubing string for oil well the liquid in the tubing string to be let out the oil return well, does not pollute ground.
Four, description of drawings: Fig. 1 is a kind of structural representation of novel bump bleeder, among the figure 1, bleeder main body 2, hollow pin
Five, the specific embodiment: in Fig. 1, hollow pin 2 is welded in the radial hole of bleeder main body 1 symmetry, and easy fault trough is arranged on the hollow pin 2.
Claims (1)
1. one kind newly clashes into bleeder, and it is to be formed by connecting by bleeder main body (1) and hollow pin (2), it is characterized in that: hollow pin (2) is welded in the radial hole of bleeder main body (1) symmetry, and the hollow pin has easy fault trough on (2).
