Increase of Accuracy of Well Bottom Position Determination by Minimization of Seismic Vibration Finding Errors


Article Preview

In the given work, on the basis of the carried out researches at the decision of seismic surveying tasks an attempt on advancement of methods and means of excitation of elastic vibrations by the generator of seismic vibrations (GSV) is made. The geometry of the real GSV differs from the ideal axially symmetric form resulting in deviations of parameters of geometry of mass (deviations of the centre of mass, main central axes of inertia), and is a consequence of the static and dynamic disbalance.The character of forces and moments acting on the GSV, as a whole and on separate units, depends on quality of the law of change of total force of resistance of escapement and return of plunger; dynamic loads resuling in occurrence of transverse waves at excitation of seismic vibrations deterioting the accuracy of determination of well bottom position are formed.
