Abstract
The utility model relates to a device for preventing the leakage of crude oil in oil pipes, which is used in the state that a pipe column drip is closed in an oil well in an oil field. The utility model is composed of a base cone, a core spindle, a lower end cover, a lower through hole, a lower sleeve, a rubber tube, an upper sleeve, an upper through hole, an upper end cover, locking nuts and an upper connection, wherein the base cone is in threaded connection with the core spindle, the lower end cover is sheathed outside the core spindle and the lower end cover is in threaded connection with the lower through hole. The upper and the lower through holes are both oblong, the lower sleeve is in threaded connection with the root part of the rubber tube, the lower through hole and the lower sleeve, the rubber tube and the upper sleeve, the upper sleeve and the upper through hole and the upper through hole and the upper end cover are in threaded connection. The lower end cover and the upper end cover are integral, the upper connection is fixed with the core spindle by the locking nuts and then the utility model can be formed. The utility model solves the problems that the existing drips in the prior art can not open pipe columns, crude oil in the pipes can only return to the ground via an overflow spray type flushing method, and the existing drips can cause crude oil external leakage, environmental pollution and lots of manpower and cost waste. The utility model can be used for the construction operation under the state that the pipe column drip is not opened.
Description
Technical field:
The utility model relates to pipe column oil drainage device in a kind of oilfield does not have the crude oil leakage device in the oil pipe that prevents used under the open mode.
Background technology:
The state tubing string that existing bleeder is not opened, have only by emitting the spray mode to propose the OIH pipe or adopting the well-flushing mode will manage interior crude oil and return out ground, relatively also well-flushing be can't implement under the serious situation in leakage, great amount of manpower and vehicle expense wasted like this.Because crude oil leaks, go back contaminated environment.Need a kind of device that prevents that crude oil leaks in the oil pipe of development.
The utility model content:
The purpose of this utility model is to provide a kind of crude oil leakage device in the oil pipe that prevents, this device can solve do not open tubing string under the state of the bleeder that exists in the prior art, have only with emitting spray or well-flushing mode will manages interior crude oil and return out ground and cause substantial oil to leak, contaminated environment is wasted the problem of a large amount of manpowers and expense.
The technical scheme that its technical problem that solves the utility model adopts is: prevent that the crude oil leakage device is made up of base cone, axle, bottom end cover, lower through-hole, lower sleeve, packing element, upper bush, last through hole, upper end cover, locking nut, top connection in the oil pipe; With base cone and axle screwed connection, bottom end cover is inserted in outside the axle, bottom end cover and lower through-hole screwed connection; Last lower through-hole is oblong, is that car becomes 6～10 identical long ellipses of spacing to form lower through-hole around pipe; Lower sleeve and the screwed connection of packing element root, below through hole and lower sleeve screwed connection, packing element and upper bush screwed connection upper bush and last through hole screwed connection, last through hole and upper end cover screwed connection; Bottom end cover to the parts between the upper end cover all connect in aggregates, and top connection and axle are fixed with locking nut.During use, this device is connected in the sucker rod lower end, in oil pipe, send into the down-hole, under the effect of the resistance of liquid and packing element and tube wall frictional force, other each parts all are in the top position with respect to axle except that axle, lower through-hole all is in opening state on this moment, and below liquid footpath lower through-hole enters the lower sleeve inner chamber.And go into to go up the upper bush inner chamber through packing element, on last through hole flows into this device oil pipe.When transferring to when giving allocation, on carry sucker rod, under resistance, pressure, packing element and the effect of tube wall friction of liquid, other each parts all are in lower position with respect to axle except that axle, through hole is in opening state on this moment, lower through-hole is in closed condition.Close at the open-minded of through hole, the pressure of this device upper end fluid column acts on the packing element inner chamber through last through hole, upper bush, and packing element is opened outward, the ring-like space around the sealing packing element.This moment, the oil column of this device upper and lower side was separated.Carry sucker rod in the continuation, the ring-like space around the packing element is in closed state all the time, and packing element pastes tube inner wall and upwards slides.Lower through-hole is in closed condition all the time, guarantees that fluid column does not leak, until mentioning well head.
The utility model beneficial effect is, this apparatus structure is simple, compact, can guarantee crude oil in the oil pipe on return, can save a large amount of expenses, avoid environment pollution; Need not push up spray or clean-out service, simplify the construction operation degree, raise the efficiency, can save great amount of manpower and expense.
Description of drawings: accompanying drawing is the utility model overall structure schematic diagram.
Among the figure 1, base cone, 2, axle, 3, bottom end cover, 4, lower through-hole, 5, lower sleeve, 6, packing element, 7, upper bush, 8, go up through hole, 9, upper end cover, 10, locking nut, 11, top connection.
The specific embodiment:
Among the figure, prevent that the crude oil leakage device is made up of base cone 1, axle 2, bottom end cover 3, lower through-hole 4, lower sleeve 5, packing element 6, upper bush 7, last through hole 8, upper end cover 9, locking nut 10, top connection 11 in the oil pipe; With base cone 1 and axle 2 screwed connections, bottom end cover 3 is inserted in outside the axle 2 bottom end cover 3 and lower through-hole 4 screwed connections; Upper and lower through hole is oblong, is that car becomes 6～10 identical long ellipses of spacing to form upper and lower through hole around pipe; Lower sleeve 5 and packing element 6 root screwed connections, lower through-hole 4 and lower sleeve 5 screwed connections, lower through-hole 4 and lower sleeve 5, packing element 6 and upper bush 7, upper bush 7 with last through hole 8, go up through hole 8 and be screwed connection with upper end cover 9; Bottom end cover 3 to the parts between the upper end cover 9 all connect in aggregates, and top connection 11 is fixing with axle 2 usefulness locking nuts 10.
