WELL DIRECTIONAL PROBE AND WELL DIRECTIONAL SURVEY SYSTEM TO DETERMINE SUBSIDANCE OF VERTICAL ROCKS AND FILLING MASS WITH ITS USE Russian patent published in 2015 - IPC E21B47/02 E21C39/00 

FIELD: instrumentation.

SUBSTANCE: suggested group of inventions relates to measuring equipment, in particular to method of creation of well directional survey systems, and can be used in mining to check the deformation processes relating rocks and filling mass. The well directional probe is suggested, containing cylindrical casing with devices measuring inclination angle of the subhorizontal well, and located in the casing pipe for installation in the said well with possibility of movement along its longitudinal axis. At that devices measuring inclination angle of the subhorizontal well are implemented by the located perpendicular to each other measuring sensor of inclination angle relatively to the horizontal plane, installed in plane of the longitudinal axis of the casing, and sensor of position monitoring of the said measuring sensor in the vertical plane by the probe rotation by the forcing casing elements. The said sensors are connected with inputs of the matching block connected with output of the said probe. From outside the casing has at least two supports secured in the bottom part of the casing at its ends, and in top part at least two spring-loaded elements are provided for continuous contact of the supports in the bottom part of the casing with the internal surface of the casing pipe. Besides the system is suggested to determine the vertical subsidence of the rocks and fill mass, including connected in series said probe, electronic block, made based on the analogue-to-digital converter with power block, interface sub-system with applied software of data acquisition and storage. At that the electronic block is equipped with the ADC and power source by digital data exchange module in real time to the said interface sub-system, that is implemented as PC with common applied software of information processing and conversion, additionally containing block of pre-processing of said sensor signals, and block of rest modes selection, connected with inputs of block of current information displaying in graphical form and test control, which output is connected with input of the block of data presentation and files storage.

EFFECT: increased accuracy of measurements of inclination angle of subhorizontal well relatively to the horizontal plane, and increased accuracy of determination of position of zones with local deformations (critical zones).
