Improvement of torsion balance of gradiometer based on the electromagnetic gimbal

(Kostitsyn V.I. Petrov Yu.P. Kulikova T.S. Danilov Iu.L. )

A comparative evaluation of gravity and gradiometer research geological objects at different depths. It is shown, that the relative measurement error gravimeter at small depths of occurrence of inhomogeneities will be greater, than for the gradiometer. The design of the weights of the second kind in the gradiometer, based on using electromagnetic suspension instead of mechanical.......

Investigation of the platform interior of the western part of the Ural on the basis of the geophysical data

(Tarantin M.V. Kostitsyn V.I. Prostolupov G.V. Chadaev M.S. Gershanok V.A. )

Complex processing of seismic and gravity data at deep seismic sounding surveys provides determination of correlations of depth dependencies of longitudinal and shear wave velocities and density. Areal gravimerty data with these surveys as a pattern allows using acquired interpretation receptions to expand the area of earth crust being investigated.......

The choice of sampling of field seismic data in time and space

(Spassky B.A. Banchikov A.I. )

On the basis of spectral analysis are discussed phenomena aliasing (frequency distortion), and especially the choice of sampling of field seismic data in time and space. With digital recording and processing the right choice of parameters sampling avoids distortion of frequency content oscillations and reduce errors of the restoration of their amplitudes.......

Logging while drilling and geosteering technology

(Shumilov A.V. Shao CaiRui Cao XianJun Zhang FuMing )

This paper introduces the development of LWD and geosteering in China, and gives the key technologies of the geosteering software developed by China university of petroleum: the well site LWD data real-time receiving, interpretation, 2D and 3D visualization and formation model updating. At last, one and validity of the independent property rights software.......
