Abstract
The pressure measuring and core supplementing device is applied to the recording of well head data of oil field oil and water well. Is characterized in that: the pressure measuring bushing body is provided with a central hole; an external thread is arranged at one end of the pressure measuring bushing body; the other end of the pressure measuring bushing body is provided with an internal thread; the outer wall of the pressure measuring bushing body is provided with a pressure relief hole, the outer end of the pressure relief hole is provided with internal threads, and the outer end of the pressure relief hole is connected with a pressure relief plug in a threaded manner; one end of the pressure relief plug is a hexagonal body, the other end of the pressure relief plug is provided with external threads, the pressure relief plug is provided with a communicating hole, the outer end of the communicating hole is a central hole, and the inner end of the communicating hole is perpendicular to the central line of the pressure relief plug. The effect is as follows: the pressure measuring compensating core is directly installed on the oil well mouth and the water well mouth, the pressure measurement is convenient, one pressure release valve is saved, and the leakage of the well mouth is reduced. The labor intensity of the post staff for recording the pressure data is reduced, and the accuracy of data recording is improved.
Description
Technical field
The utility model relates to oil in the oilfield exploitation, well well head data admission technical field, and particularly the isolated plant of oil, the admission of Water Well mouth pressure is that core is mended in a kind of pressure measurement.
Background technology
At present, in the oil exploitation process, admission oil, well casing pressure data generally adopt the clip pipe nipple are installed outside sleeve valve, then load onto common pressure measurement and mend core, connect again the pressure measurement valve, last setting pressure table, this mode operating process trouble, mainly exist drawback to have: it is many that (1) easily produces leakage point; (2) need to connect a pressure measurement valve, the waste material; (3) be subjected to the bad adjustment of limiting pressure surface direction of rubber belt sealing; (4) time length pressure measurement valve fits badly.(5) be installed in and easily lose outward.
The utility model content
The purpose of this utility model is: provide a kind of pressure measurement to mend core, directly load onto pressure measurement and mend core on oil, well pressure measurement pipeline, pressure measurement is convenient, saves a relief valve, has reduced the well head seepage.
The technical solution adopted in the utility model is: core is mended in pressure measurement, comprises pressure measurement benefit core body and pressure release plug, and it is cylindrical that the core body is mended in pressure measurement, and the core body is mended in pressure measurement centre bore; An end of mending the core body in pressure measurement has external screw thread, and external screw thread is taper pipe thread, can be fixed on the pressure measurement pipeline; The other end of mending the core body in pressure measurement has internal thread, energy setting pressure table; It is characterized in that: the outer wall of mending the core body in pressure measurement has a relief hole, and relief hole is inner to be communicated with centre bore, and there is internal thread the outer end of relief hole, and a pressure release plug has been threaded in the outer end of relief hole; Described pressure release plug one end is hexahedron, and the other end has external screw thread, and the pressure release plug has intercommunicating pore, hole centered by the outer end of intercommunicating pore, and the inner of intercommunicating pore is vertical with the center line of pressure release plug.
The use that core is mended in the summary pressure measurement.Consult Fig. 1.To commonly use on the pressure measurement benefit core wall and open a relief hole 3, and adopt pressure release plug 4 to carry out shutoff.Lay sealing mat and fix pressure meter at the root of internal thread 2, make it sealing.External screw thread 1 end that core is mended in pressure measurement is fixed on oil, the well pressure measurement pipeline and just can conveniently measures oil, pressure of well data.
The beneficial effects of the utility model: at oil, well well head, directly load onto pressure measurement and mend core, pressure measurement is convenient, saves a relief valve, has reduced the well head seepage.This device is made simple, and cost is low, and is easy for installation, is difficult for losing.Alleviate the labour intensity that the post employee enrolls PRESSURE DATA, improved the accuracy of data admission.
Description of drawings
Fig. 1 is that the cored structure generalized section is mended in the utility model pressure measurement.
Among the figure, the 1-external screw thread, the 2-internal thread, the 3-relief hole, 4-pressure release plug, core body, 6-centre bore are mended in the 5-pressure measurement.
The specific embodiment
Embodiment 1: mend core as example take a pressure measurement, the utility model is described in further detail.
Consult Fig. 1.Core is mended in the utility model pressure measurement, comprises pressure measurement benefit core body 5 and pressure release plug 4, and it is the ladder cylindrical that core body 5 is mended in pressure measurement, and it is the centre bore 6 of 8mm that pressure measurement benefit core body 5 has diameter.An end of mending core body 5 in pressure measurement has external screw thread 1, and external screw thread 1 is 51/2, and " taper pipe thread can be fixed on the pressure measurement pipeline.The internal thread 2 that energy setting pressure table is arranged at the other end of pressure measurement benefit core body 5.The relief hole 3 that it is 6mm that the outer wall of mending core body 5 in pressure measurement has a diameter, relief hole 3 is inner to be communicated with centre bore 6, and there is the internal thread of M8 the outer end of relief hole 3, and a pressure release plug 4 has been threaded in the outer end of relief hole 3; Described pressure release plug 4 one ends are hexahedron, and pressure release plug 4 other ends have the external screw thread of M8, and pressure release plug 4 has intercommunicating pore, hole centered by the outer end of intercommunicating pore, and the inner of intercommunicating pore is vertical with the center line of pressure release plug 4.All accuracy of threads require should be able to bear the pressure of 25Mpa.
