Abstract
The utility model relates to a helical type oil-water well pressed operating loading indicator matched with a repair work device of a high-pressure oil water well, which is composed of a force sensor 1, a fixed sleeve 2, a regulating screw 3, a display panel 4 and a signal wire 5. The utility model has the advantages of simple structure, convenient operation, easy installation, high sensitivity, etc. In the process of high-pressure oil water well without pressing well sealed work, the indicator can be used for intuitively displaying the size and the direction of load received by a pressure device. When the load reaches a defined value, the device can also alarm in time, therefore the indicator can effectively avoid generating safety misadventure. The utility model is suitable for popularization and application.
Description
Technical field:
The utility model relates to a kind of well head set-up that is used for keeping in repair with the hydraulic oil well use of Operating Pressure matched with devices.
Background technology:
Along with the continuity of oil-field development process, the work of oil-water well maintenance activity is increased, and the borehole operation workload is increasing.At present, the on-the-spot hydraulic oil well maintenance Operating Pressure device that uses uses unidirectional weight indicator usually when carrying out the tubing string rountrip.Because tubing string both had been subjected to the self gravitation effect in not kill-job of the hydraulic oil well sealing operation process, be subjected to simultaneously the effect of top power on the underground high-pressure fluid again, the two with joint efforts may be up or down, and unidirectional weight indicator can only show one, when the operation worker operates, as having lost eyes, thereby exist accident potential.When too high or tubing string is met card when borehole pressure,, thereby can not in time take counter-measure, safety in production is caused serious threat because of load demonstration not can't be judged.
Summary of the invention:
The purpose of this utility model is to provide a kind of and can intuitively shows the suffered magnitude of load of pressue device, direction and can in time report to the police the display thereby the screw oil water well working with pressure that can avoid security incident to take place is loaded in not kill-job of hydraulic oil well sealing operation process.
The utility model is to realize like this.This device is made up of force cell, fixed muffle, adjusting screw(rod), signal wire and display panel, and the force cell lower end is connected with fixed muffle by adjusting screw(rod), and a side is connected with display panel by signal wire.During use, force cell is hinged with below the cylinder pedestal of pressue device bottom with screw thread.Before the normal lower tubular column, opening power, pressue device does not bear load this moment, and the display panel displayed value is zero, if display panel does not show zero, clicks reset key, and display panel promptly returns zero.During normal lower tubular column, pressue device bears load, force cell upper end or lower end are strong, but can not exist effectively simultaneously, when there is pressure (being that down-hole pressure is greater than oil pipe and pressue device own wt) down-hole, the application point of sensor and pressue device is in the sensor lower end, the instrument displayed value be on the occasion of; When the down-hole did not have pressure (down-hole pressure is less than oil pipe and pressue device own wt), the force position of sensor and pressue device was in the sensor upper end, and the instrument displayed value is a negative value; When pressue device bears load when reaching regulation numerical value, this device display panel is reported to the police immediately.
The utlity model has simple in structure, easy to operate, advantages such as installation is easy, sensitivity height, in not kill-job of oil-water well sealing operation process, utilize it can show the size and Orientation of the suffered load of pressue device intuitively, when load reaches regulation numerical value, and can in time report to the police, thereby can effectively avoid the generation of security incident, be suitable for and apply.
Description of drawings:
Fig. 1 is structure of the present utility model and installment state synoptic diagram thereof, and wherein label " 6 " is the pressue device cylinder pedestal.Fig. 2 is this device principle of work block scheme.
Embodiment: enforcement of the present utility model is described further below in conjunction with accompanying drawing.
The utility model is made up of force cell 1, fixed muffle 2, adjusting screw(rod) 3, display panel 4 and signal wire 5, and force cell 1 lower end is connected with fixed muffle 2 by adjuster bar 3, and a side is connected with display panel 4 by signal wire 5.Wherein, force cell 1 is screw shaped, and load sensor is housed in it, and the upper and lower end center pit is respectively equipped with the internal thread that is connected usefulness with cylinder pedestal 6 with adjuster bar 3, and a side is provided with the tube head that is used to pick out signal wire 5.Fixed muffle 2 upper and lower parts are respectively equipped with screw, and the middle part is provided with cavity, are uniformly distributed with 4 through holes along the circumference.Display panel 4 adopts the LED LCD, it is a rectangular form dial plate, card is provided with bearing load numerical value display screen and on ﹠ off switch, reset key, alarm lamp, is provided with the work system that is made of amplifier, A/D converter, reference source, single-chip microcomputer, house dog, BCD decoding/driver in the disk body.The utility model course of work is as shown in Figure 2: rise in the lower tubular column process at the high pressure oil water well working with pressure, by the millivolt signal of force cell 1 output after signal wire 3 reaches amplifier in the display and amplifies, deliver to A/D converter and carry out analog to digital conversion, send single-chip microcomputer to carry out accurate computing then, the instantaneous value of thrust of gained is suppressed computing through digital filtering, dynamic load, after BCD decoding, send display panel to show again.IMP813 house dog wherein is used to prevent the deadlock of single-chip microcomputer, guarantees system's operate as normal.
