Errors minimization in geophysical wells position determination
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 mass geometry parameters (deviations of the center of mass, main central axes of inertia) that 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 total force change of escapement and plunger return resistance; dynamic loads resulting in occurrence of transverse waves at excitation of seismic vibrations deterioting the accuracy of determination of well bottom position are formed. Application of the given technique will allow to minimize transverse components of a seismic wave up to a level of balance errors function and to increase the accuracy of well bottom determination.
