Abstract
A combined bailing oil producing well head device mainly solves the problems of difficult detachment and maintenance, easy damage of well head as no anti-collision device, etc. for old bailing oil producing well head device in the prior art. The utility model is characterized in that a well head seat main body (5) is directly arranged on a casing joint (6), an anti-collision box (3) is connected with the well head seat main body (5) through a circlip, the inside of the anti-collision box (3) is provided with an anti-collision device; a packing box (2), a pulley block (1) and the anti-collision box (3) are connected one another through thread, wherein, three sealing elements are arranged in the packing box (2); the pulley block is composed of two parallel arranged pulleys, and a pumping wire rope passes through a gap between the two pulleys and enters into the well. The combined bailing oil producing well head device adopts a combined structure, is convenient for detaching and maintaining, and has the characteristics of preventing well head damage under the protection of the well head anti-collision device arranged inside.
Description
Technical field:
The utility model relates to a kind of wellhead assembly in the petroleum works field, relates to a kind of bailing wellhead for production specifically.
Background technology:
At present, in petroleum works field, oil field, normally used is old-fashioned bailing wellhead for production.This old-fashioned bailing wellhead for production utilizes wire rope directly to be lowered into the shaft bottom dragging for oily device exactly from well head top, carry out oil salvage operation, and then utilize the reciprocal rotation of vehicle mechanical, oil from the shaft bottom bailing to well head, be driven in the oil truck by the union connector at last.By long application, find that this old-fashioned bailing wellhead for production exists following problem: at first, this old-fashioned bailing wellhead for production is an integral type mechanism, and each parts can not be dismantled, and has brought great inconvenience for loading and unloading, maintenance work; Secondly, pumping steel wire rope and well head top frictional force are bigger, very easily damage wellhead assembly; In addition, well head top does not have anticollision device, collision-prevention device, when dragging for oily device and promote, easily bumps with well head, causes the well head damage.
The utility model content:
In order to solve the problem that old-fashioned bailing wellhead for production is not easy to dismantle maintenance, the fragile well head of no anticollision device, collision-prevention device; the utility model provides a kind of combined type bailing wellhead for production; this kind combined type bailing wellhead for production is taked fabricated structure; be convenient to dismounting and maintenance, and have the advantages that to be not easy to damage well head under the protection of the well head anticollision device, collision-prevention device of installing within it.
The technical solution of the utility model is: this kind combined type bailing wellhead for production comprises assembly pulley, packing box, crashproof box, union connector, wellhead receptacle main body and cover pipe connector.Wherein, described wellhead receptacle main body directly sits on the cover pipe connector, has the union connector that can directly be connected with oil truck on it.Described crashproof box is connected with the wellhead receptacle main body by jump ring, and anticollision device, collision-prevention device is equipped with in crashproof box inside; Described packing box, assembly pulley and crashproof box interconnect by screw thread, and 3 potted components wherein are housed in the packing box, and assembly pulley is made of side by side two pulleys, and pumping steel wire rope enters in the well by two pulley room spaces.
The utlity model has following beneficial effect: at first, this kind combined type bailing wellhead for production adopts fabricated structure, and whole device can be separated into each independent parts, so be convenient to very much dismounting, install and keep in repair.Secondly, the assembly pulley design is adopted in the upper end of this device, adopt two pulleys to design side by side, pulley is placed in the middle, when wire rope moves up and down, make the friction of wire rope and well head change rolling friction into, thereby greatly reduce the frictional force between wire rope and the well head by sliding friction, this assembly pulley makes wire rope pass through from the well head center simultaneously, and wire rope is had centralizing function preferably.And, in this device, be positioned at the well head upper end crashproof box is installed, when on dragging for oily device, moving, can effectively reduce the collision effect of oily device of dragging for to well head, in addition, because crashproof box adopts circlip type to be connected with the wellhead receptacle main body, therefore can effectively slow down and drag for the impact force of oily instrument well head.Except that above characteristics, 3 potted components are equipped with in the packing box inside on crashproof box top in this device, and purpose is to improve the sealability of well head, so that effectively prevent crude oil leakage, prevents blowout.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
1-assembly pulley among the figure, the 2-packing box, the crashproof box of 3-, 4-union connector, 5-wellhead receptacle main body, 6-overlaps pipe connector.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this kind combined type bailing wellhead for production, comprise assembly pulley 1, packing box 2, crashproof box 3, union connector 4, wellhead receptacle main body 5 and cover pipe connector 6, wherein said wellhead receptacle main body 5 directly sits on the cover pipe connector 6, described crashproof box 3 is connected with wellhead receptacle main body 5 by jump ring, anticollision device, collision-prevention device is equipped with in crashproof box 3 inside, described packing box 2, assembly pulley 1 and crashproof box 3 interconnect by screw thread, 3 potted components wherein are housed in the packing box 2, assembly pulley is made of side by side two pulleys, and pumping steel wire rope enters in the well by two pulley room spaces.
When being connected with well head, to well head, 5 of wellhead receptacle main bodys play a supportive role cover pipe connector 6 by screwed connection.Union connector 4 directly is connected with oil truck, and packing box 2 sealings are better, can effectively prevent crude oil leakage and blowout.When carrying out oil salvage operation, wire rope is by the assembly pulley 1 on this device top, at the bottom of oily instrument lower going-into-well directly will be dragged in the middle duct of this device, when on dragging for oily device, carrying, utilize the reciprocal rotation of vehicle mechanical, carrying on the pumping steel wire rope, crude oil moves with dragging on the oily instrument.Between assembly pulley 1 and the wire rope because crude oil and drag for the gravity of oily instrument, rub each other, assembly pulley 1 is because constantly rotation of friction, this moment, force of sliding friction changed rolling friction into, thereby can reduce the frictional force on wire rope and well head top greatly, prolong the life-span of this device, and assembly pulley 1 can make wire rope from the dynamic(al) correction center.When the referred union of crude oil connector 4, crashproof box 3 can effectively reduce the impact force of dragging for oily device well head, thereby prevents to damage well head.Crude oil directly enters oil truck from union connector 4, and after hours, this device can be removed from oil well easily.
