Abstract
The invention discloses an oil pipe anti-overflow tool for direct flushing and indirect flushing, and relates to the field of industrial machinery. The oil pipe anti-overflow tool comprises an upper connector, a lower connector and an anti-overflow body, wherein the upper connector is connected with a righting rod which is connected with a reverse valve, the reverse valve is connected with a reverse valve base, a valve spring is arranged on the correcting rod and connected with the reverse valve, one end of the reverse valve base is connected with a forward spline type circumferential through hole, and the other end of the reverse valve base is connected with a reverse valve through hole. Normally-opened through holes are formed in the anti-overflow body. The lower end of the anti-overflow body is connected with a piston body which is connected with piston body springs. Two flow-limiting aperture passageways are designed and arranged, and therefore it can be ensured that a tubular column can be smoothly descended under the condition that no spraying or spoiling happens to an oil pipe, circulating direct and indirect flushing can be sufficiently conducted multiple times, the flow limiting effect is not changed when the tubular column is descended, and therefore the work schedule is effectively accelerated. The oil pipe anti-overflow tool is simple and ingenious in design and convenient to apply and popularize.

Summary of the invention
A kind of being applied to is the object of the present invention is to provide to prevent in perforating job process about spraying and the Preventing Tubing Overflow Tool in The Course of Well Cleanout And Reverse Cleanout of flooded conditions.
The technical scheme of technical solution problem of the present invention is: a kind of Preventing Tubing Overflow Tool in The Course of Well Cleanout And Reverse Cleanout, comprise top connection, lower contact and anti-overflow body, described top connection is connected with righting rod, described righting rod is connected with reverse valve, described reverse valve is connected with reverse valve seat, the length of described righting rod is 15-25cm, described righting rod is provided with valve spring, described valve spring is connected with reverse valve, one end of described reverse valve seat is connected with forward spline type perimeter throughbores, the reverse valve through hole of the other end of described reverse valve seat, described anti-overflow body is provided with often opens hole, the lower end of described anti-overflow body is connected with piston body, described piston body is connected with piston body spring.
As further improvement, described forward spline type perimeter throughbores inside is provided with rete.
As further improvement, described rete is polypropylene material.
As further improvement, described piston body is round table-like.
As further improvement, the described quantity often opening hole is 10, and the described radius often opening hole is 4mm.
Beneficial effect: in the present invention, the most conference of oily liquid in pipe produces the pressure of 0.1 MPa, owing to often opening the current limliting in hole, extends the time that oil pipe stream is full, can not produce oil pipe and to spray and spoil over phenomenon, when in oil pipe, liquid level is lower than sleeve pipe liquid level 0.3 MPa, reverse valve forced compression spring, reverse valve through hole is opened, more extend the time that oil pipe stream is full, also phenomenon of spraying and spoiling over should not be there is, when tubing string is hampered or needs forward well-flushing, pressurization in oil pipe, circular platform type piston body is upper, under the effect of lower pressure reduction, compress valve spring and forward spline type perimeter throughbores is opened, add that the passage often opening hole carries out reverse circulation well-flushing, in oil pipe after distress resolves, spline type perimeter throughbores can by piston body shutoff under the effect of piston body spring, along with the lowering velocity impulse force of tubing string is larger, piston body shutoff also larger, when needing well-flushing when being again hampered, repeatedly can carry out well-flushing operation of just pressurizeing in oil pipe, until blowout prevention is anti-overflow in oil pipe, thus effectively accelerate job schedule, forward spline type perimeter throughbores inside is provided with the rete of polypropylene material, reaches the object of cleaning forward spline type perimeter throughbores by changing rete.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details.
As shown in Figure 1: a kind of Preventing Tubing Overflow Tool in The Course of Well Cleanout And Reverse Cleanout, comprise top connection 1, lower contact 2 and anti-overflow body 3, described top connection 1 is connected with righting rod 11, described righting rod 11 is connected with reverse valve 4, described reverse valve 4 is connected with reverse valve seat 5, the length of described righting rod 11 is 15-35cm, described righting rod 11 is provided with valve spring 8, described valve spring 8 is connected with reverse valve 4, one end of described reverse valve seat 5 is connected with forward spline type perimeter throughbores 6, the other end of described reverse valve seat 5 is connected with reverse valve through hole 12, described anti-overflow body 3 is provided with often opens hole 7, the lower end of described anti-overflow body 3 is connected with piston body 9, described piston body 9 is connected with piston body spring 10, the most conference of oil liquid in pipe produces the pressure of 0.1 M Pa, owing to often opening the current limliting in hole, extend the time that oil pipe stream is full, oil pipe can not be produced to spray and spoil over phenomenon, when in oil pipe, liquid level is lower than sleeve pipe liquid level 0.3 MPa, reverse valve forced compression spring, reverse valve through hole is opened, more extend the time that oil pipe stream is full, also phenomenon of spraying and spoiling over should not be there is, when tubing string is hampered or needs forward well-flushing, pressurization in oil pipe, circular platform type piston body is upper, under the effect of lower pressure reduction, compress valve spring and forward spline type perimeter throughbores is opened, add that the passage often opening hole carries out reverse circulation well-flushing, in oil pipe after distress resolves, spline type perimeter throughbores can by piston body shutoff under the effect of piston body spring, along with the lowering velocity impulse force of tubing string is larger, piston body shutoff also larger, when needing well-flushing when being again hampered, repeatedly can carry out well-flushing operation of just pressurizeing in oil pipe, until blowout prevention is anti-overflow in oil pipe, thus effectively accelerate job schedule, forward spline type perimeter throughbores inside is provided with the rete of polypropylene material, reaches the object of cleaning forward spline type perimeter throughbores by changing rete.
