Description
Technical field
The utility model relates to drilling technology field, particularly about a kind of real-time monitoring system that may be used for milling windowing task in window sidetracking operation process.
Background technology
Casing side tracking is oil field, especially old filed, effective measures of later stage raising crude oil production capacity under development, it makes full use of old well top hole, significantly can reduce drilling cost, in maintenance with under improving original well pattern structure condition, dried-up well is brought back to life, old well upgrades, and extends the oil reservoir exploitation time limit, improves final oil recovery.Current situ of drilling well extensive use whipstock-milling windowing method, inclined-plane even milling on sleeve pipe that it utilizes milling to bore along wedge deflection tool goes out the round and smooth window of a plagioclase, the quality of window quality, very large to next step construction infection, and after drill bit exit window, because the pressure of the drill is low, hole deviation is little, the outer annular space of old well creeps into along bottom easily to cause drilling tool, cannot creep into stratum, thus cause the failure of windowing task, cause heavy economic losses.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind ofly can wear away window sidetracking real-time monitoring system to the sleeve pipe that oil drilling casing sidetracking carries out Real-Time Monitoring.
Window sidetracking real-time monitoring system worn away by sleeve pipe described in the utility model, is made up of the vibrating sensor connected successively, wave filter, signal amplifier and signal receiving device.
Preferably, described vibrating sensor is acceleration transducer.
Or more preferably, described vibrating sensor is arranged on casing head and well head place, sleeve pipe place.
Or more preferably, described signal receiving device is computer.
The utility model is owing to taking above technical scheme, it has the following advantages: the utility model regards the vibration of drill bit in casing window sidetracking construction as signal source, by monitoring the condition of construction of drill bit in down-hole at the casing head of well head place sensor detection thimble vibration signal of sidetracked hole and the attached subaerial vibration signal of well head, thus can give and follow-uply judge whether windowing-process provides reliable and stable monitored data with the distance of main borehole smoothly and after calculating drill bit exit window.The utility model structure is simple, easy to operate, is not subject to the impact of operating condition and operating environment, can not affects normal wellbore construction, can be widely used in the Real-Time Monitoring of various milling window sidetracking.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the utility model can be worn away window sidetracking real-time monitoring system by a kind of sleeve pipe and realize, and this system comprises being arranged on needs attached subaerial acceleration transducer 3, the signal filtering amplification subsystem 4 of the acceleration transducer 2 at window sidetracking well 1 casing head of well head place, window sidetracking well 1 well head and a computer 5.Wherein signal filtering amplification subsystem 4 is made up of traffic filter and signal amplifier.Regard the vibration of window sidetracking well drill bit 6 as signal source, in window sidetracking, drill vibration signal is propagated along the sleeve pipe of window sidetracking well 1.The ground vibration signal that the attached subaerial acceleration transducer 3 of the vibration signal of vibration acceleration sensor 2 monitoring sleeve, well head gathers, passes to signal filtering amplification subsystem 4 by wired or wireless.Computer 5 is sent into after signal filtering amplification subsystem 4 pairs of vibration signals carry out amplification filtering process.Namely computer 5 obtains sleeve pipe and wears away window sidetracking Real-time Monitoring Data.It is follow-up these data can be transferred to data acquisition and analysis system or by artificial to these data analysis.
As shown in Figure 2, the flow chart of data processing of described data collection and analysis subsystem is: first data collection and analysis subsystem gets rid of ground other vibration signals (personnel according to the two-way vibration signal received, vehicle, drilling equipment etc.) interference, judge, identify the drill vibration signal propagated through sleeve pipe that acceleration transducer 1 gathers, and the drill vibration signal recognized is judged to the condition of construction of drill bit by signal waveform, if find that in drill bit windowing-process, signal strength signal intensity is constant for a long time, wave form varies is violent, then illustrate that drill bit is at cutting sleeve pipe or cement sheath, now system sends early warning, construction party should stop sidetracking and check Construction State.If signal strength signal intensity reduces by more than 10 times when finding that signal strength signal intensity is comparatively windowed, signal waveform flattens cunning, then can judge that drill bit has been windowed and successfully enter stratum, now can according to the Strength Changes of bit signal, the relative distance of the foundation real-time calculation side drill bit of model and sidetracking window, thus split the drill-through journey Real-Time Monitoring of reveal, and judge that whether windowing-process is smooth, with the distance of main borehole after calculating drill bit exit window.
