EN: One of the directions of increase in oil and gas production is creation of modern information and measuring systems of drilling. The Specialized Computer System (SCS) of orientation of the boring instrument is one of subsystems and carries out the following functions: on the basis of deep information on technological parameters of a driving sets the maximum speed of movement of a face on a design trajectory, ensures safety and quality of drilling operations. SCS of orientation of the boring tool on the basis of modern equipment has to provide a production intensification, improvement of quality of production and decrease in product cost.
The article is devoted to working out of methods and ways of transformation of parameters of a well curvature in specialized computer system (SCS) of orientation of the boring machine of creation of mathematical models of primary converters taking into account errors from destabilizing factors with preliminary mathematical processing of the measuring information.
Inclinometers are still applied to measurement of a magnetic azimuth, an antiaircraft tilt angle of a well with a magnetic needle now. In designs of modern converters as the sensor of an azimuth ferroprobes are used. With use of ferroprobes it is possible to define not only an azimuth, but also an antiaircraft corner. The most perspective scheme of use of ferroprobes is the scheme with rigidly fixed converters.
Use as sensitive elements the ferroprobes of converters allows to reduce diameter of a borehole shell to 38–40 mm. As ferroprobes converters aren't subject to influence of vibrations, on their basis creation of vibration-proof converters of antiaircraft and vizirny corners is possible. Lack of electronics allows to expand the range of working temperatures considerably.
Thus, creation of converters on the basis of same the ferroprobes of sensors, is an actual technical task.
The mathematical model of an inclinometer on the basis of rod the ferroprobes of converters who, in comparison with known, allows to increase efficiency of determination of parameters of a curvature of a well due to simplification of computing process by 4–5 times is developed.
