In field of petroleum exploitation, drilling well is the engineering of a complexity, can produce bulk information, and drilling information is the necessary condition that ensures drilling safety, quality and efficient.Can realize comprehensive assessment and real-time drilling Engineering Control to drillng operation for the collection of drilling information, improve precision and the efficient of Drilling Control, reduce drilling cost.
At present, the method for realization continuous-tube rig downhole communication has Electromagnetic Wave Method, sonic method and drilling fluid pulse method etc.The electromagnetic wave transfer of data be signal with low frequency from the underground ground of passing to, this method is transmitted in both directions, can up and down transmission in well, do not need circulation of drilling fluid.Its data transmission capabilities is close with the drilling fluid pulse remote measurement.The advantage of this method is that data transmission bauds is very fast, is suitable for transmission orientation and geologic information parameter in the wellbore constructions such as conventional mud, foam mud, air drilling, laser drill; Shortcoming is that stratum media is larger on the impact of signal, and the stratum electromagnetic wave of low-resistivity can not pass, and the distance of electromagnetic transmission is also limited, is not suitable for ultra-deep wells, at present at most can only be in 3000 meters dark wells the transmission of data.Sonic method is a kind of transmission method that transmits sound wave or seismic signal by drilling rod.The sound wave remote measurement can significantly improve data transmission rate, makes with boring data transmission rate to improve an order of magnitude, reaches 100bit/s.The same mud circulation that do not need with the electromagnetic wave remote measurement of sound wave remote measurement, still, the low intensity signal that well produces and the acoustic noise that is produced by drilling equipment make detectable signal very difficult.The drilling fluid pulse method is that the downhole controller by MWD changes the parameter that the various sensors in down-hole measure into the signal of telecommunication, then change the drilling fluid pulse signal into after commanding impulse generator with the various Signal codings in down-hole, upwards send to ground transaucer, signal interpretation and data handling system by the drilling well fluid column in the drilling rod, carry out the picking up of signal, change, decipher, processing etc.
Generally use at present, the technology comparative maturity be the drilling fluid pulse method because compare additive method, the drilling fluid pulse method is comparatively simple, and is little on normal drillng operation impact.Pressure pulse transmits by fluid column in the drilling rod earthward with the speed of 1200~1500m/s, and each parts of down-hole all are contained in the non magnetic drill collar.Because hold the parts of MWD instrument, so its internal diameter is larger than common drill collar.
Rig undershaft communication system based on Fibre Optical Communication Technology can address the above problem, yet, subsurface environment is abominable, existing underground communica tion device can't normally use in the subsurface environment of HTHP, directly affect the normal operation of whole undershaft communication system, increased the potential safety hazard of wellbore construction when having limited drilling efficiency.
