The premises that everything goes well with your work is carried out such as contrast, FRACTURING DESIGN.At present, when measuring drilling depth during exploration logging, use such as
Under type:
1) traditional method is to use the measurement rope indicating length mark to measure, the degree of depth that manually recorded measurement rope puts down, its
Shortcoming is that efficiency is low, measurement error big, and the method is only applicable to Vertical Well and measures.
2) more advanced well drilling depth measuring instrument, based on photoelectric encoder or Hall element.One is to be arranged on
The displacement of the signal reflection drilling tool of the photoelectric encoder output on winch drum, the measurement error of the method is easily shaken by working site
Dynamic impact, additionally photoelectric coder rapid wear under vibratory impulse environment, service life is limited.In order to not make error too big, typically
Use the photoelectric encoder of low precision, therefore certainty of measurement is the highest.
3) another method is by steel wire penetrating pulley, pulley is provided with and measures the Hall element that pulley rotates, and it is defeated
Go out signal to be counted by processor, and obtain the degree of depth.Because being built the general limited resolution of sensing circuit by Hall element,
Therefore, the method depth survey misses by a mile.In actual applications, if the excessive velocities of steel wire rope folding and unfolding, depth survey is by mistake
Difference is also bigger than the first metering system, and is very difficult to control, and the method is only applicable to Vertical Well equally and measures.
4) in the drilling process of colliery, having a kind of method with brill well depth survey is Acoustic Reflection Method, and the method is that employing one is bulky
Head makes power beat drilling rod and produces the sound wave propagated along drilling rod, and by tapping the time difference between moment and echo, and sound wave is at gold
The spread speed belonged in material can obtain drilling depth.The advantage of the method is to measure the well depth of arbitrary orientation, its fatal defects
Being that the artificial dynamics tapped cannot be grasped, fathom and be difficult to control to, error is relatively big, and concordance is poor.
Therefore, existing well depth measurement scheme exists that efficiency is low, measurement error big, restricted application, is difficult to measurement while drilling
Etc. problem.
