FIELD: petroleum geophysics, particular, determination of parameters of deviation of directional wells. SUBSTANCE: according to the first version of the offered method, systematic error of the transducer is determined, by setting a number of values of measured parameters and determining the measured value of the parameter at the output of transducer, and graph of variation of systematic error is constructed. Continuous function is determined, which describes the graph most accurately and is used as correction to change the set values of parameters for the measured one. According to the second version, the range of variation of the measured value of parameter is divided into uniform intervals, found for each of measured values of parameters separating the intervals are differences between measured and preset values, graph is constructed and analytic expression is determined which most accurately approximates the graph and used as correction compensating the systematic error. EFFECT: higher accuracy of measurements. 2 cl, 1 dwg |
