Abstract
A kind of measuring, alarming, tracing and transmitting in conjuction with drill, it is applicable to when oil drilling or geological drilling to be the warning tracer that various drilling measuring equipments are done measurement parameter.It by the drilling rod housing be connected the lead that measurement while drilling is provided with output and form, it is characterized in that: one or several signal magazines are arranged on the drilling rod housing, electric cap, isotopic tracer and seal cover are housed in the signal magazine.Transfinite behind the signal obtaining physical quantity that the measurement while drilling setting records by lead, ignite electric cap, be dispersed in isotopic tracer in the mud and be brought to well head, record, reach the purpose of warning spike by the isotope measure instrument.Simple in structure.
Description
A kind of measuring, alarming, tracing and transmitting in conjuction with drill, it belongs to oil and geological drilling measureing equipment, is applicable to when oil drilling or geological drilling to be the warning tracer that various drilling measuring equipments are done measurement parameter.
When modern oil exploitation drilling well or geology investigation creep into, for measuring the various running parameters in the drilling well, developed various measurement while drilling devices, be used for measuring at drilling process.But accomplish that the most difficult is the problem of signal being returned ground with boring with survey and measuring-signal is returned ground in good time.Because the existing transmission means transfer rate that adopts is very low, thereby also can't obtain high-quality data flow.In the measurement of drilling course, whether some physical quantitys are surpassed warning value want timely display alarm, so that take corresponding measure, prevent the generation of accident.The situation such as particular value of display alarm when for example, surpassing to(for) the unexpected variation of down-hole pressure, temperature, water content.
The objective of the invention is to invent a kind of information warning spike can surpass warning value to the physical quantity that measurement while drilling obtains the time to last receiving system, it does not use lead to be sent to well head, and is simple and practical.
Showing of structure of the present invention such as accompanying drawing 1, it is made up of the lead 2 that drilling rod housing 1, connection measurement while drilling are provided with output, it is characterized in that: one or several signal magazines 3 are arranged on drilling rod housing 1, electric cap 4 is equipped with in the bottom in signal magazine 3, with the plain tracer 5 of bit table, be useful on the seal cover 6 of sealing at ordinary times at signal magazine 3 oral areas.
Operating principle of the present invention is summarized as follows.Connect the detonation circuit that lead 2 is connected to the measurement while drilling device, surpass when setting the warning value when boring physical quantity that measurement mechanism records, send the ignition electric pulse by the measurement while drilling device, this signal of telecommunication is by connecting the electric cap 4 that lead 2 is sent to bottom in the signal magazine 3, electric cap 4 is detonated, the seal cover 6 that pops spills in the outer mud isotopic tracer 5, finishes the purpose of warning spike.Because the circulation of mud, above-mentioned isotopic tracer is brought to well head, uses radiac, just can record the existence and the kind of isotopic tracer, thereby obtain the warning message of down-hole.
Structure of the present invention is very simple, and it can be connected in the lower end of drilling rod, links together with the measurement while drilling device, does not require to use lead to be sent to well head.Present isotope tracer measurement sensitivity is all very high, only needs very small dosage just can detect, and therefore can not cause any pollution.
