Abstract
The utility model discloses a device which is suitable for monitoring the vertical displacement and the movement speed of an idler car in petroleum well drilling and well logging. The utility model is characterized in that a graduation monitor is installed on an overhead travelling crane on a headframe, the monitor outputs pulse signals by measuring the graduation number of a pulley on the overhead travelling crane, and the pulse signals are transferred to a computer system to be processed to obtain the high-precision data of vertical displacement and motion. The utility model has the advantages of convenient adjustment, low cost, convenient operation, high security, etc.
Description
The utility model relates to the depth monitor in oil drilling, the well logging process, particularly tourist bus is carried out the monitoring of vertical displacement and movement velocity.
The degree of depth is a very important parameter in oil drilling, well logging technology, also is the important evidence that the depth of stratum mark is provided for other parameter.Usually the degree of depth is to obtain by the vertical displacement of monitoring travelling block (abbreviation tourist bus).In existing technology, the monitoring device that is used for the degree of depth has multiple: as overhead traveling crane roller formula monitoring device, it is to adopt a roller to be pressed on the derrick crown pulley, along with photoelectric encoder of rotation drive of pulley, reflect the vertical displacement amount of tourist bus by processing to the signal of telecommunication that photoelectric encoder produced.But, because operation in the open air is subjected to the influence of butter and dust between pulley and the roller, easily produces relatively and slide, skidding appears, thus the measure error of causing, and install inconvenient.Also having a kind of is the rope type monitoring device, promptly is one and measures rope on the water tap of tourist bus bottom, measures the motion state of tourist bus with the mode of measuring this rope motion state.The problem that this device exists is to install and use inconvenience.Another is a winch photoelectric encoder formula monitoring device.Adorn a photoelectric encoder at the winch drum shaft end, be coiled in the displacement that the length of steel wire rope on the cylinder is measured tourist bus by measurement.Though this mode is easy for installation, debugging is trouble very, and precision is not high.
At the problem that above-mentioned prior art exists, it is little that the purpose of this utility model provides a kind of volume, and Installation and Debugging are convenient, reliable operation, and can adapt to open-air adverse circumstances, the life-span is long, a kind of tourist bus vertical displacement monitoring device that certainty of measurement is high.
Realize that the scheme that the utility model purpose is taked is: the calibration monitoring device is installed, is comprised monitor, divided wheel two parts, and form jointly with computer processing system on derrick crown.Divided wheel can replace with the pulley on the derrick crown pulley mechanism.Monitor is placed on day vehicle frame, by divided wheel number of divisions purpose being monitored vertical displacement and the movement velocity of calculating tourist bus.After promptly with monitor divided wheel being measured, output pulse signal is passed to computer system and is handled, thereby obtains required monitoring result.Can not satisfy under the situation of calibration requirement at pulley wheel muscle, so just a light slotted vane or other similar attachment device need be installed on pulley, as divided wheel.
Monitor of the present utility model is to be made by sensing element, and volume is little.It will be installed on overhead about 40 meters high overhead traveling cranes, carries and install very convenient.In addition, replace divided wheel (the wheel muscle number of pulley can satisfy calibration require) generally speaking, to save the expense of making divided wheel with pulley.Therefore, the utlity model has and implement simple, low, safe and reliable, the monitoring accuracy advantages of higher of cost.
Description of drawings:
Figure one is a monitoring scheme of installation of the present utility model.
In Fig. 1, label (2) is a crown sheave wheel muscle, and label (1) is the installation site of sensing element E and F, and it is wide that distance about 1/2 is taken turns muscle between the two.
Monitor of the present utility model is to be made by sensing element. Sensing element is preferential photoelectric tube or the approach switch of adopting in the utility model. Be installed on the derrick crown with the securing member that is easy to dismantle, owing to be operation in the open air, the outside of photoelectric tube should be added with protective cover. Protective cover can be made with metal material, also can make with plastics or other material. Computer in the utility model preferably adopts SCM system, because being known technology, no longer describes in detail in this specification.
Claims (3)
1, a kind of depth monitor comprises computer processing system and calibration monitoring device.It is characterized in that: the calibration monitoring device is made up of monitor and divided wheel two parts, and is installed on the derrick crown.
2, depth monitor according to claim 1 is characterized in that: divided wheel can be the pulley on the overhead traveling crane, a light slotted vane also can be installed as divided wheel on overhead traveling crane.
3, depth monitor according to claim 1, it is characterized in that: monitor is made by sensing element, and protective cover is equipped with in the outside, and this preferably adopts photoelectric tube or near switch.
