Abstract
The utility model relates to a pin roll type oil-water well pressure operation load display which is matched with a high-pressure oil-water well pressure operation repair device to use. The utility moThe utility model relates to a pin-type load display for the operations under pressure on an oil water well, which is used with devices for the maintenance under pressure on a high-pressure oil water del is composed of a force cell 1, a display 2 and a signal wire used for connecting the force cell 1 with the display 2. The utility model has the advantages of simple structure, convenient operationwell and which comprises a force sensor (1), a display (2) and a signal line (3) for connecting therebetween. The utility model has advantages of simple structure, convenient operation, easy installat, easy installation, high sensitivity, etc. During non-well-pressure and seal operation carried out on the high-pressure oil-water well, the utility model can visually display the magnitude and the diion and high sensitivity, and capability for directly displaying the value and direction of loads on the compression device during the snubbing operation under sealed conditions in the high-pressure orection of the load of a pressure device; when the load reaches predetermined value, the utility model can alarm in time; therefore, the utility model can effectively prevent unsafely accidents from oil and water well. When the load reaches the preset valve, the pin-type load display provides the alarms in time, thereby avoiding the occurrence of safety accidents. The utility model is easy to popuccurring, and is easy to be popularized and used. larize and use.
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 pin type 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 kind display is made up of force cell, display panel and signal wire three parts, and force cell one end that is made into bearing pin shape is connected with display panel by signal wire.During use, force cell is laterally penetrated and is fixed in the sill bearing and the corresponding eyelet of hydraulic cylinder bearing of pressue device.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 " 4 " is a pressue device hydraulic cylinder bearing, and label " 5 " is a pressue device sill bearing.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.
As shown in Figure 1, the utility model is made up of force cell 1, display panel 2 and signal wire 3, and force cell 1 one ends are connected with display panel 2 by signal wire 3.Wherein, force cell 1 housing is bearing pin shape, and left-right symmetric is provided with 2 horizontal through hole on it, and load sensor is housed in it, and both sides are fixed with pin respectively.Display panel 2 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.
