Definitions

  • the invention is available for a non-standard geophysics and may be used in a dry seismic event. 5 PREVIOUS LEVEL OF TECHNOLOGY

  • a method for recording seismic data ( ⁇ 5 ⁇ , 41 ⁇ 4152691.1979) is known, which involves the use of separate recording blocks for each unit. It uses mobile receivers and a source of seismic waves.
  • the block of receivers contains a group of sensors,
  • Another method of seismic observations (5 ⁇ , ⁇ 541134) includes transient changes in the oscillations for each wave and the registration of all seismic programs.
  • the posed problem is solved in order to simultaneously excite the other waves of the 5th and 5th types.
  • the registration of seismic waves is carried out by seismic receivers, each of which contains a sensor, which is connected to a corner of 45 parts of the earth Further, and the processing of the recorded records for the well-known matters, they calculate the right value for the business.
  • Received by the sensors of the I, II, III, IV components can be divided into the following physical 5 components at a time:

  • Obvious difference between seismic programs Fig. 1 and Fig. 2 - 6 - testifies to how convenient the equipment is for separating the fields, and also for the presence of strange seismic programs in the traditional seismic programs.
  • the latter fact says that, in addition, put a symbol for the variable, for example, between Rev. 5 and the seismic receiver, but this is not a big deal. Failure to do so could result in errors, especially in the case of power seismic process faults.
  • the distance between the ignition points should be reduced by 2 times compared with the calculated for the use of 10 only continuous. When this is done, a small increase in the speed of the process is required, since it is desirable to carry out the same in the case of small parts.

Abstract

Le procédé de l'exploration sismique de l'invention consiste à produire simultanément des ondes élastiques P et S, et à procéder à un enregistrement à l'aide de détecteurs sismiques contenant quatre dispositifs de détection identiques, lesquels sont agencés de manière à avoir le même angle de relèvement par rapport à un point. Une fois les enregistrements obtenus traités, on calcule les coordonnées cartésiennes rectangulaires du vecteur de champ pleine onde à chaque point de détection. Le fait de comparer les modules de projection cartésiens calculés pour un point de détection donné avec le module vectoriel intégral au niveau de ce point permet d'identifier trois ondes monotypiques polarisées de façon linéaire du type PP, SV et SH ainsi qu'une onde polarisée de façon non linéaire, lesquelles constituent un signal utilisable.
