Abstract
A pollution-preventing device for a pumping rod in oil well operation belongs to the technical field of oil production. The utility model comprises a press cap, a base, an outer cylinder, a double-horn shaped sealing rubber scraping cylinder, an upper cushion ring, a lower cushion ring and two supporting semi-rings, the device is arranged with a universal joint which consists of a base, a lower joint, a ball head and a ball head press cap, wherein the lower joint is arranged with an oil outlet nozzle fixed by the connecting method to a well head. The double-horn shaped sealing rubber scraping cylinder adapts to a wide diameter range of the pumping rod and has excellent sealing effect, thereby being suitable for passing and sealing of the pumping rod body, and also of the connecting collar as well as the arranged a righter. The universal joint ensures the scraping rubber cylinder to be always concentrical to the pumping rod in the whole pumping process, and therefore, reduces eccentric wear. The oil outlet nozzle arranged on the lower joint can realize the directional release of the wellhead pressure to prevent blowout, and therefore, has excellent pollution preventing effect. The utility model is applicable to both vertical wells and inclined wells and thereby having outstanding popularizing values.
Description
Technical field
The utility model relates to a kind of oil field when carrying out the oil well operation, carries and takes out antipollution device in the bar process, belongs to the well recovery technical field.
Background technology
Oil well operation environmental control system has many: it is antipollution both to be useful on ground, and it is antipollution also to be useful on the down-hole; Be useful on and carry oil pipe, also be useful on to carry and smoke bar.The environmental control system of taking out bar is carried in existing oil well operation, by pressure cap, urceolus, up and down gasket ring, support semi-ring, scraping packing element and bearing etc. and constitute, bearing is fastened on the oil well mouth.This environmental control system is only applicable to straight well and the little rod string of vary in diameter scope uses, for inclined shaft with take out the rod string that has centralizer on the bar and just can't use, carry the roofbolt of taking out in the bar process and rock easy generation roofbolt eccentric wear all around, often take place intermittently to gush, can not realize the directed release of well head pressure, preventing polluting effect is poor.
The utility model content
The purpose of this utility model is exactly to take out the deficiency that the bar environmental control system exists at existing carrying, and a kind of preventing polluting effect is provided good oil well operation is carried and taken out the bar environmental control system.
The purpose of this utility model is by proposing the improvement of taking out the bar environmental control system and realize existing, the oil well operation is carried and is taken out the bar environmental control system, comprise the urceolus 2 interior scraping packing elements 6 of installing that pressure cap 1 and bearing 7 are threaded, gasket ring 3, following gasket ring 4 and two environmental control systems that support semi-ring 5 formations on the plug-in mounting of the interior outside of scraping packing element 6, it is characterized in that environmental control system is provided with the universal joint of taking oil nozzle 9 out of, universal joint is installed and is connected on the bearing 7 of environmental control system.Described universal joint is by comprising that bearing 7, lower contact 8 and bulb 10, bulb pressure cap 11 constitute, and bulb 10 is threaded on the bearing 7, and the bulb pressure cap is rolled on the bulb 10 for 11 armfuls, and lower contact 8 is threaded with bulb pressure cap 11.Oil outlet 9 is arranged in the lower contact 8.Described scraping packing element 6 is a double horn shape caulking gum.Between scraping packing element 6 and the support semi-ring 5 pressure bladder that is out of shape with the scraping packing element is arranged.Lower contact 8 is connected and fixed with the oil well mouth.
The oil well operation is carried and is taken out the bar environmental control system, in the oil well operation, carry or descending taking out in the bar process, when taking out the bar body by caulking gum, garden hole shape caulking gum in the middle of the double horn shape caulking gum tightens to be taken out on the bar body, when taking out bar box cupling and centralizer by caulking gum, strut tubaeform caulking gum, the caulking gum aperture becomes big and becomes big along with diameter of sucker rods, takes out bar box cupling and centralizer smoothly by hole, caulking gum garden.Take out after bar box cupling and centralizer pass through, the caulking gum aperture diminishes along with diameter of sucker rods and dwindles, and the inverted tubaeform caulking gum is all the time to taking out the bar body, taking out bar box cupling and centralizer and play sealing, blowout prevention, removing crude oil and prevent contamination.
Connect (also claiming bulb to connect) owing to be provided with universal joint, like this when on carry or descending taking out takes out in the bar process that bar rocks all around and when deflection takes place, the scraping packing element all around rocks and deflection thereupon, make scraping packing element and roofbolt be tending towards the concentric situation all the time, significantly reduce the eccentric wear phenomenon, can obtain better sealing blowout prevention, preventing polluting effect.This carry take out the bar environmental control system to rod string and on the vary in diameter accommodation of box cupling, centralizer big.Using method is, the rod string lifting sub is from up to down passed the double horn shape caulking gum of this device, and the lower end is equipped with takes out bar with the down-hole and connect corresponding concentric reducer and box cupling; After proposing polished rod, dismantle valve orchid on the well head big four, lifting sub is connected with the bar of taking out that the down-hole proposes; On carry and taking out about bar 20CM, remove and take out the bar elevator; The lower contact of this device is connected in the well head oil pipe leans on, tighten screw thread, on carry and take out bar and make box cupling and centralizer by device, be stuck in taking out below the bar box cupling of device upper surface with taking out the bar elevator, transfer and take out bar and be sitting in and take out on the bar elevator, unload and take out bar; Continue to repeat to carry and take out the bar operation and all take out bar until having carried.With flexible rubber hose the oil outlet overflowing liquid is introduced well head oil spilling pond.
The utility model is rational in infrastructure simple, manufactures easily, and cost is low.Double horn shape caulking gum scraping packing element is wide to taking out shank diameter accommodation, good sealing effect, both adapted to the sucker rod body by and sealing, also adapt to box cupling on the rod string and the centralizer that is equipped with by and sealing.Be provided with universal joint, can make scraping packing element and roofbolt be tending towards the concentric situation all the time in the bar process carrying taking out, reduce eccentric wear.In lower contact, be provided with oil outlet, can realize in the bar process that well head pressure is directed and discharge anti-gushing haveing suffered to carry taking out.The oil well operation is carried and taken out the bar environmental control system, and is easy to install, and preventing polluting effect is good, can be applicable to that straight well can be applicable to inclined shaft again, has the excellent popularization using value.
