Description
Technical field
The utility model relates in the oil exploitation the subsidiary equipment of oil gas well, particularly a kind of slips type down-hole instrument hanger.
Background technology
In the oil exploitation process, often need carry out subsidiary to parameters such as the pressure of oil gas well down-hole, temperature, flows with special tester.The test jobs of oil gas well in the prior art normally adopts winch by steel wire or cable instrument to be sent into certain degree of depth of down-hole, so that the parameter under the measuring well.When needs are measured for a long time, winch will be parked in Jing Chang, usage ratio of equipment is low, increases use cost, the fluid if the down-hole is corrosive, then the material to steel wire and cable requires to improve, however the life-span of steel wire and cable also can shorten, and because steel wire or cable must be retained in the down-hole always, to the also corresponding raising of the seal request of well head, when well head pressure is higher, if the well head seal failure will bring great risk to surrounding environment and safety work.
For addressing the above problem, invented the soft hanging tool that is located and frees (soft setgauge hanger) abroad, this instrument can be suspended on being located on the pipe nipple under the lower going-into-well in advance.This being located has two to three grooves on the pipe nipple, corresponding with the key on the hanging tool, and when the position of pipe nipple was located in hanging tool arrival, the key on the hanging tool entered in the groove that is located pipe nipple, realizes hanging.But the well that is located pipe nipple that this instrument only is only applicable to be lowered in advance, present most oil wells all do not have setting to be located pipe nipple, are subjected to very big restriction on using.Chinese patent ZL01240371.7 discloses a kind of oil well and has thrown in disconnecting apparatus, be by instrument being arrived preposition down with steel wire, throw in a weight at well head then, pound on the instrument, make instrument be stuck in the down-hole, realize the optional position of instrument at oil pipe is located, but this device is because complex operation also needs to use specially-made wellhead equipment, and success rate is not high, in practice, this instrument is difficult to apply widely.
The utility model content
Shortcomings and deficiencies at above-mentioned prior art existence, the purpose of this utility model is to provide a kind of slips type down-hole instrument hanger, and this hanger can be suspended on tester the optional position of oil well easily, and simple to operate, use cost is low, is easy to apply.
For achieving the above object, slips type down-hole instrument hanger of the present utility model comprises body 1 and lower contact 2, also comprise slips 3, connecting rod 4, clamping plate 5 and spring 6, described body 1 is by last, following two parts constitute, top is provided with throws in connector 7, the bottom is provided with chimera 8, extend to form a wedge shape inclined-plane 9 downwards from the end of described chimera 8, the bottom of embedding and body 8 is provided with chute 10, slips 3 and wedge shape inclined-plane 9 are enclosed within the outside of embedding and body 8 with matching, pin 13 passes the top of connecting rod 4, the end of slips 3 and chute 10 are bound up it movably, the end of connecting rod 4 connects with lower contact 2 by pin 14, be provided with suspension arrangement 15 in the lower end of described connecting rod 4 or the end face of lower contact 2, the two ends of spring 6 are hung on chute 10 and the suspension arrangement 15, and clamping plate 5 are enclosed within the terminal of slips 3 and are fixed on the top of the chute 10 on the body 1 by screw 11.
Further, described body 1 and with the slips 3 of body 1 tabling be platy structure;
Further, described slips 3 by endways mutually embedding and and two slips sheets being riveted together form;
Further, described slips 3 is provided with pawl with the outside that wedge shape inclined-plane 9 matches;
Further, the top of described chimera 8 is wedge shape inclined- plane 9, and 9 bottoms of extending are rectangular configuration along the wedge shape inclined-plane;
Further, the angle on the wedge shape inclined-plane 9 on described chimera 8 tops is 5.7 °;
Further, the length of chute 10 is 70 millimeters;
Further, chute 10 ends are provided with a pin 12, and the upper end of spring 6 hangs on the pin 12;
Further, connecting rod 4 is made of two rectangular slabs up and down;
Further, the suspension arrangement 15 in described connecting rod 4 lower ends is the pin of riveting between two link rod plates.
Compared with prior art, advantage of the present utility model is that it does not need to be lowered in advance the pipe nipple that is located in the down-hole, do not need special wellhead equipment yet, just can be suspended on tester the optional position of oil pipe exactly, simple to operate, use cost is low, and owing to adopted flat structure, the sectional area of hanger is little, uses conventionally test equipment to be lowered to operation, influence the oil gas flow channel hardly, can not cause choked flow to oil pipe after hanger band instrument is gone into the well the success suspension, it is mobile unimpeded in oil pipe also can to satisfy oil stream in the time of test, even oil well is equipped with hanger, can not influence the ordinary production of oil well because of its existence underproduction yet; In addition, because body and connecting rod have all adopted conventional rectangular configuration, need not the Special Equipment processing, thereby manufacturing process is simple, cost reduces greatly; Use slips type down-hole instrument hanger of the present invention its advantage when a certain degree of depth of oil well is carried out long term monitoring more obvious, after the oil well monitor instrument is suspended in the oil well the predetermined a certain degree of depth, the all devices on steel wire and ground all can be withdrawn, and need not staff on duty in the whole test process.After operation was finished, used personnel and equipment all can be alloted other places and carries out operation in this operation process, and so both safety greatly reduced cost of production again, thereby had improved operating efficiency greatly.
