Description

Oil well hole condition Real-Time Monitoring mechanism
Technical field
The present invention relates to the detection of oil well, specifically refer to oil well hole condition Real-Time Monitoring mechanism.
Background technology
Oil well is comparatively strict on verticality requires, the verticality of general oil well needs to remain within the scope of certain angle and can meet subsequent job, just need rationally to detect oil well verticality when excavating oil well, in order to avoid hole deviation and affect oil exploitation, therefore, instrument is needed to measure at any time, the not only complex structure of survey tool in the past, and use very bothers, each measurement all needs the long period, has greatly dragged slowly the progress that digs a well.Meanwhile, because oil well is comparatively dark, excavating tools is when excavating, part instrument can be subject to bottom pressure impact and occur some faults, therefore, also needs to guarantee the pressure of oil well correspondent section within the specific limits, to ensure the normal use of instrument, also can change suitable instrument according to pressure simultaneously.
Summary of the invention
The object of the present invention is to provide oil well hole condition Real-Time Monitoring mechanism, solve survey tool complex structure in the past, awkward problem.
Object of the present invention is achieved through the following technical solutions:
Oil well hole condition Real-Time Monitoring mechanism, comprise the cylindrical shell of closed at both ends, connecting rod is fixed with in the upper end of described cylindrical shell, two side upper hinge in the middle part of cylindrical shell is connected with support bar, the movable end of support bar is provided with roller, the bottom of described cylindrical shell offers groove, the adjustment seat of annular and groove threaded engagement, and the inner side of described adjustment seat is provided with the taper seat matched with support bar hinged end; Also comprise two pressure sensors, described pressure sensor to be fixed on cylindrical shell and to be communicated with through the controller of connecting rod with the external world by wire, and described support bar is provided with spring, and the movable end of spring is connected with pressure sensor.When the present invention works, according to the situation of oil well internal diameter size, rotate adjustment seat to make it axial movement occurs on groove, and then realize increasing or reducing two support bars be hinged on cylindrical shell, this device is placed in oil well to be detected, artificial traction bars makes device enter duty, be positioned at roller on support bar movable end directly and oil well contact internal walls, and then make device slowly moving down along in oil well, meanwhile roller is can produce an opposition to support bar with during oil well contact internal walls, this active force makes spring be compressed, the pressure sensor of the spring other end is then by the size cases record of this opposition, when there is local dip in oil well inside, the opposition that the support bar of cylindrical shell both sides and roller are subject to is different, therefore the pressure signal that receives of two pressure sensors is not identical yet, the pressure value record that two pressure sensors will be subject to separately, be sent in controller, by the force value of artificial calculation element at inclination borehole wall place and the difference of device in the force value at vertical borehole wall place, again divided by the coefficient of elasticity of spring, finally draw the shift value of device in oil well inclination place, draw two line segments, again by constantly drawing shift value point, finally draw the verticality situation of whole oil well, with fast and easy recover petroleum, after detection, again by artificial traction bars, cylindrical shell is made to shift out oil well fast, the present invention is simple and quick, the verticality of oil well can be detected fast, and due to the tunable performance of support bar, while raising applicability, solve survey tool complex structure in the past, awkward problem.
The wheelbase size of two described rollers is identical with the internal diameter of oil well.Wheelbase between two rollers is arranged identical with the internal diameter of oil well, can ensure that cylindrical shell is in folding process, roller all the time with oil well contact internal walls, namely spring is made to be in stable compressive state all the time, ensure that the pressure signal that pressure sensor receives is stablized, the initial pressure numerical value accurate stable drawn.
Described spring is torsionspring.As preferably, the extruding of the borehole wall or the resistance of fluid can be subject in the folding process of support bar in oil well, and then the active force causing spring to be subject to oppositely constantly changes, traditional spring cushioning effect is in its axial direction better, when constantly switching between its axis of working stress and radial direction, spring is easy to metal fatigue and then causes impaired, and the present invention adopts torsionspring, the working stress on different directions can be born, substantially increase application life of the present invention.
The present invention compared with prior art, has following advantage and beneficial effect:
1, the present invention is after detecting, again by artificial traction bars, cylindrical shell is made to shift out oil well fast, the present invention is simple and quick, the verticality of oil well can be detected fast, and due to the tunable performance of support bar, while raising applicability, solve survey tool complex structure in the past, awkward problem;
2, the wheelbase between two rollers arranges identical with the internal diameter of oil well by the present invention, can ensure that cylindrical shell is in folding process, roller all the time with oil well contact internal walls, namely spring is made to be in stable compressive state all the time, ensure that the pressure signal that pressure sensor receives is stablized, the initial pressure numerical value accurate stable drawn;
3, the spring cushioning effect in its axial direction that the present invention is traditional is better, when constantly switching between its axis of working stress and radial direction, spring is easy to metal fatigue and then causes impaired, the present invention adopts torsionspring, the working stress on different directions can be born, substantially increase application life of the present invention.
