The method is characterized in that: the diameter of the upper sealing pipe (1) is thinner, the inner diameter of the lower sealing pipe (2) is larger than the outer diameter of the upper sealing pipe (1), and the upper sealing pipe and the lower sealing pipe are connected and sealed through a sealing joint (3); the upper sealing pipe (1) can be retracted into the lower sealing pipe (2) during transportation to reduce the total length; when the pressure is measured, the upper sealing tube (1) can be extended out to meet the requirement of a lower pressure gauge; the utility model has the advantages of light weight, labor saving in moving, and capability of reducing the operation height of the well head.
Description
The present invention relates to a kind of lubricator that the oil field is used for being installed in when oil well carries out the pressure measurement operation well head.
Each oil field is hydraulic oil, the air-flow ejection that prevents downforce timing down-hole carrying out oil well pressure measurement operation at present, and the methods that adopt are fixed pressure measurement lubricators more, and its structure is made up of sealed tube, steel wire packing box, support pulley and pressure release valve etc.; Earlier the sealed tube lower end of lubricator is installed on the high pressure gate of well head during operation, unload the steel wire packing box of sealed tube upper end then, the pressure gauge rope socket is connected with the pressure measurement steel wire in the back packs sealed tube into from the upper end, refilled the steel wire packing box, close the pressure release valve on the sealed tube, open the high pressure gate on the well head, transfer the pressure measurement steel wire, will carry out pressure measurement under the pressure gauge lower going-into-well by support pulley and the steel wire packing box that install the sealed tube upper end.This lubricator shortcoming in use is that body is long, heavy, needs when packing pressure gauge on well head to operate at the height more than 4 meters.
The objective of the invention is for solving the deficiency that existing lubricator exists, design a kind of light, body weak point, can reduce the telescopic pressure measurement lubricator of well head operation height.
The objective of the invention is to finish: a kind of telescopic pressure measurement lubricator that is used for oil field testing pressure down hole operation by following measure, form by last sealed tube, lower seal pipe, seal nipple, steel wire packing box, pressure release valve, wireline pulley and lower contact etc., it is characterized in that: it is thinner to go up the sealed tube diameter, the lower seal bore is greater than last sealed tube external diameter, and upper and lower sealed tube connects sealing by seal nipple; Steel wire packing box and wireline pulley are installed in last sealed tube upper end, and the lower end is connected with the lower seal pipe by seal nipple; Seal nipple is installed in lower seal pipe upper end, and lower contact is installed in the lower end, and pressure release valve also is housed on the tube wall.
Purpose of the present invention can also be finished by following measure: go up sealed tube and be one section internal diameter is about the pressure gauge total length greater than pressure gauge, length half metal tube, two ends are processed with screw thread, are fixed with the support of wireline pulley on the outer wall; The lower seal pipe is about half the metal tube that a segment length is the pressure gauge total length, and two ends all are processed with screw thread; Seal nipple is made up of reducer union, gland and sealing mat etc., reducer union is one section thick-walled metal tubulose structure, the upper end is connected with gland by screw thread, all be processed with screw thread on lower end and the inwall, gland is a bowl structure that Open Side Down, center drilling, and the aperture is slightly larger than the sealed tube external diameter, the lower end is connected with reducer union by screw thread, between gland and the reducer union sealing mat is housed; Lower contact is one section metal tube, and two ends and endoporus all are processed with screw thread.
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is telescopic pressure measurement lubricator structure chart.
Telescopic pressure measurement lubricator is made up of last sealed tube (1), lower seal pipe (2), seal nipple (3), steel wire packing box (4), pressure release valve (5), lower contact (6) and wireline pulley (7).Last sealed tube (1) is that one section internal diameter is half seamless pipe of pressure gauge total length greater than pressure gauge, length, the upper end is connected with steel wire packing box (4) by screw thread, weld the fixedly pulley bracket of wireline pulley (7) on the outer wall, be processed with the screw thread of slightly larger in diameter on the outer wall of lower end in the seamless pipe external diameter, can with being threaded of the endoporus of the endoporus of the reducer union of seal nipple (3) or lower contact (6); Lower seal pipe (2) is that one section internal diameter is slightly larger than half the seamless pipe that sealed tube (1) external diameter, length are the pressure gauge total length, the upper end is connected with seal nipple (3) by screw thread, the lower end is connected with lower contact (6) by screw thread, and pressure release valve (5) also is installed on its tube wall; Seal nipple (3) is made up of reducer union, gland and sealing mat etc., reducer union is a drive sleeve, diameter of bore is slightly larger than the external diameter of sealed tube (1), connect lower seal pipe (2) by the screw thread lower end, the upper end connects gland, endoporus is processed with screw thread and can be connected with last sealed tube (1) lower end, gland is that one that Open Side Down is bowl-shape, center drilling, its slightly larger in diameter is in the external diameter of last sealed tube (1), there is box thread to be connected on the inwall, between reducer union and the gland seal gasket is housed with reducer union; Lower contact (6) is one section seamless pipe, and the upper end is connected with lower seal pipe (2) by screw thread, and the lower end is processed with the screw thread that can be connected with well head, and its endoporus also is processed with the screw thread that can be connected with last sealed tube (1) lower end; The present invention is steel component.
Can stretch in the lower seal pipe (2) to lower contact (6) upper end going up sealed tube (1) during carrying, sealed tube in the rotation (1) makes the screw thread of its lower end be connected with the inner hole thread of lower contact (6) and fixes, to reduce total length; Earlier telescopic pressure measurement lubricator is holded up during pressure measurement, lower contact (6) is installed on the well head high pressure gate, unload steel wire packing box (4), the pressure measurement steel wire that will pass steel wire packing box (4) is connected with the pressure gauge rope socket, again pressure gauge is put into sealed tube (1), unclamp the gland of seal nipple (3), screw out and on put on sealed tube (1), collide until the screw thread of its lower end and the reducer union inner hole thread of seal nipple (3), it is screwed in again and fix, the gland of screwing hermetic joint (3) installs steel wire packing box (4) then, close pressure release valve (5), open the well head high pressure gate and then can transfer pressure gauge and carry out pressure measurement to the down-hole; Tripping out manometric method after the pressure measurement is then undertaken by the reverse of above-mentioned downforce operation.
The present invention in use has light, carries laborsavingly, can reduce the advantages such as well head operation height.
