Abstract
The utility model relates to an acquisition clamping hoop for vibration signals of a drilling column, which is used for axial and reverse vibration signals of a drilling rod of petroleum. The acquisition clamping hoop for vibration signals of a drilling column is mainly composed of half rings 1, a battery 2, a barn cover 3, an amplifier 8, a sensor 9, and a wireless transmitter 10, wherein, more than two half rings 1 are mutually connected by hinges 6 and are hooped on the periphery of a kelly bar 13, and the closing points of the half rings are fastened by fastening devices 12. The utility model overcomes the risk that a measuring joint which originally needs to be connected to the drilling column is easy to twist off; the clamping hoop can not bear any stress transfer of the drilling column, and usage is reliable. The utility model is suitable for a plurality of methods of top driving and rotary table driving of a drilling machine; usage and installation are convenient, and application ranges are wide.
Description
The utility model relates to the collection of object vibration signal and transmission, is to be used for gathering the oil drilling drilling rod axially and turn round clamping band for collecting vibration signals of drilling rod to vibration signal.
When oil drilling, the drill bit of rig, down-hole equipment, drilling rod and suspention all can produce vibration, this vibration has reflected the state of rig work, the working condition and the strata condition that also can reflect underground drill stem simultaneously, timely and effectively to the analysis of drillstring vibrations, can understand lithology and prediction accident with boring, effectively control drilling process.At present, drillstring vibrations and control have entered practicality, it is ripe that measuring technique is tending towards, patent GB2274667 has just proposed a kind of example of application, the measurement joint that this gathers vibration usefulness, directly be connected drill with ferrule with bar water tap bottom, sensor is arranged in it, measure amplifying circuit, wireless transmission and electric supply installation, sensor is converted to the signal of telecommunication with the axial acceleration of drill string with turning round to acceleration, amplifies the back and is transferred to the well site record analysis by comprehensive wireless transmitting system, finishes control.
Above-mentioned measurement joint is connected on the drill string, himself to bear the Stress Transfer effect of drill string complexity, very high to its requirement of strength, in a single day twist off in the joint during use and can cause major accident, there is application risk, particularly measure joint and be only applicable to rig drill string top and drive working method, and the most of rig of China is the rotating disk type of drive, can not install, thereby limit being extensive use of of this measuring method.
The utility model purpose is to provide a kind of drill string Stress Transfer effect of not bearing, and does not have to twist off risk, is applicable to drill top-drive and rotating disk type of drive and clamping band for collecting vibration signals of drilling rod easy to install and use.
The utility model is achieved through the following technical solutions: clamping band for collecting vibration signals of drilling rod mainly is made up of semi-ring 1, battery 2, storehouse lid 3, amplifier 8, sensor 9, wireless launcher 10 etc., plural semi-ring 1 connects with hinge 6 mutually and binds round around kelly bar 13, and the closure place of semi-ring 1 is fastening with fastener 12.
The utility model also is achieved through the following technical solutions: interconnective battery 2, mercury switch 4, amplifier 8, sensor 9 and wireless launcher 10 are housed on semi-ring 1, have communicating pipe 7 to connect between the semi-ring 1, the handgrip 5 of protrusion also is housed on semi-ring 1.The fastener 12 of semi-ring 1 can be used bolt.Mutual vertically arranged accelerometer is arranged in the sensor 9.
The utility model advantage is that clip does not bear any Stress Transfer of drill string, does not have any application risk, is applicable to that drill top-drive and rotating disk drive multiple mode, and easy to install and use, applicable surface is extensive.
The utility model description of drawings is as follows:
The structural representation of Fig. 1 the utility model embodiment; The lateral view of Fig. 2 the utility model Fig. 1.
Describe the utility model in detail below in conjunction with accompanying drawing.Clamping band for collecting vibration signals of drilling rod mainly by semi-ring 1, battery 2, storehouse lid 3, amplifier 8, sensor 9 and wireless launcher 10, etc. form, plural semi-ring 1 connects with mobilizable hinge 6 mutually, form the hoop that can install at any time and take off the closure place of semi-ring 1 is fastened on kelly bar 13 with fastener 12 around, fastener 12 can be with the also available hook of bolt.The handgrip 5 of protrusion also is housed on the semi-ring 1, is convenient to clamping.Sensor 9, amplifier 8, wireless launcher 10, mercury switch 4 and battery 2 are housed on semi-ring, communicating pipe 7 is arranged between the semi-ring 1, be convenient to the connection of circuit.The outside of semi-ring 1 has storehouse lid 3 to be used for preventing dust.Mutual vertically arranged accelerometer is arranged in the utility model sensor 9, the axial acceleration of drill string is converted to the signal of telecommunication and sends into amplifier amplification 8 with turning round to acceleration, be transferred to the analysis that keeps a record of well site receiver by wireless launcher 10 and antenna 11 then, the effect of mercury switch 4 is to make circuit connect automatic powered-down when drilling rod stops boring when drilling rod rotates.The utility model sensor 9, amplifier 8, wireless launcher 10 and mercury switch 4 etc. all adopt commercially available universal component, accelerometer can be used the YD-3 type, amplifier amplifies for the high resistant computing, optional CA3140 integrated circuit, the optional MC2831 integrated circuit of wireless launcher and frequency modulation(PFM) receives optional MC3361 or 3362 integrated circuits.
