Technical field
The utility model relates to a kind of equipment of measuring drilling well gradient or direction, espespecially a kind of deep-well electromagnetic wave while-drilling measuring system.
Background technology
In Process of Oil Well Drilling, grasping accurately, in real time hole deviation data is key factors that can whether hole trajectory control be qualified, complete smoothly drilling well task.
Current monitoring hole deviation technology is divided from method of operating, is to be mainly divided into wired monitoring and wireless monitor.
Wired monitoring is by land cable winch, by cable, by instrument G.I.H, uses gyroscope principle, keep drill string static, after instrument imaging, by winch, instrument is proposed to ground, take out film, the video picture of Xian's film, then reading out data, this tilt measurement is also single-shot survey.Single-shot survey method advantage is low operation cost, is still being widely applied at present in low cost, shallow well drilling well.But the weak point of single-shot survey is also outstanding: during the operation of (1) deviational survey, drilling well is produced and must be stopped, and affects bit speed; (2) when instrument is worked in well, drill string must be static, increased the risk that lock of tool drilling occurs; (3) by cable rise, lower instrument, the operating time is long; (4) can only survey the hole deviation data of a point, hole trajectory control difficulty at every turn; (5) instrument manual operation factor affects the accuracy of data.
Without money monitoring while drilling, i.e. MWD (measurement while drilling) technology development in nearly 2 years is swift and violent, is requisite monitoring while drilling instrument in directional well in oil drilling, horizontal well.This system is comprised of inserting tube, pulser, battery, ground system.Before drill string enters well MWD apparatus installation in nearly bit drilling tool, by inserting tube, send instruction to pulser, a series of pulse signals are sent in the motion of pulser servo valve, by mud, pulse signal is passed to ground system, ground system receives, decodes, processes and shows and comprise the various downhole datas such as hole deviation, orientation in real time.MWD technology is current state-of-the-art monitoring while drilling technology, but also has the following disadvantages: (1) operating cost is high; (2) affected by mud displacement, mud property larger, easily lose code or no signal; (3), when deep-well, ultradeep well operation, pressure influence pulser is normally worked, and causes and cannot monitor.
