Definitions

  • the invention relates to a system of processing and presenting drill hole measurement data such as obtained by taking a measurement in drill hole.
  • An additional object of the invention is to make these data of drill hole measurements available in a cost-efficient and user-friendly manner.
  • the system of processing and presenting data of drill hole measurements as obtained by taking a measurement in a drill hole is characterized, in that the drill hole measurement data are divided into successive depth bands having a predetermined depth window; in that for each depth band a spectral analysis is carried out providing for each such depth band a spectral band; in that the spectral band of each individual depth band is compared with climate-related deposition cycles, such as the known Milankovitch cycle data, that relate to the examined area; and in that the predetermined depth window of the depths bands is adjusted to realize an optimal correlation between the spectral band of at least one depth band and the respective cycle or cycles.
  • climate-related deposition cycles such as the known Milankovitch cycle data
  • the depth window of the various depth bands is predetermined. This depth window determines the resolution and consequently the accuracy with which the drill hole measurement data can be translated into geologically relevant information.
  • a further aspect of the invention relates to the system being characterized in that the cycle pattern of the spectral band is determined by a first depth band; in that the cycle pattern of the first spectral band is used as prediction for the spectral band of a second depth band succeeding the first depth band; in that the occurrence of a discontinuity in a predicted spectral band is determined in relation to the actual measurement data; and in that said discontinuity is an indication for a geologically significant boundary layer.
  • the cycle pattern of the spectral band is determined by a first depth band; in that the cycle pattern of the first spectral band is used as prediction for the spectral band of a second depth band succeeding the first depth band; in that the occurrence of a discontinuity in a predicted spectral band is determined in relation to the actual measurement data; and in that said discontinuity is an indication for a geologically significant boundary layer.
  • the system is characterized in that the discontinuities, which are determined with respect to the successive depth bands, are integrated with the variable parameter being the depth to which the drill hole measurement data refer.
  • the variable parameter being the depth to which the drill hole measurement data refer.
  • the system according to the invention may, for example, be implemented on a stand-alone computer such as a PC to which a graphical image unit is coupled. Such a system will allow the presentation of measuring data such as shown in the appended single figure.
  • the figure shows an image as may appear on a display of a system according to the invention.
  • the image is comprised of a left half and a right half.
  • the left half of the image shows the discontinuities determined with as variable parameter (y-axis) the depth of the drill hole.
  • Said discontinuities may entail a deviation to the left or a deviation to the right, having a particular geological significance.
  • a deviation to the left generally signifies an increase in sediment formation, whereas a deviation to the right signifies a decrease.
  • the drill hole measurement data are divided into successive depth bands, with for each depth band a depth window as determined by the user of the system. Subsequently, a spectral analysis is carried out for each depth band, providing a spectral band that relates to each such depth band. The spectral bands are then compared for each separate depth band with the (Milankovitch) cycle data applicable to the examined terrain, to arrive at the best possible coordination between these known data and the measurement data.
  • the depth window can be adjusted.
  • the discontinuities are determined by determining the cycle pattern of the spectral band pertaining to a first depth band and to use this as prediction for the spectral band pertaining to a second depth band succeeding said first depth band.
  • This predicted spectral band relating to the second depth band is compared with the actual measurement data that have become available and with the differences between the predicted values and the discontinuities constituting the measurement values shown in the left half of the image.
  • the right half of the image shows the graph that results when the discontinuities determined in relation to the successive depth bands and which are shown in the left half of the image, are integrated with as variable parameter the depth to which the drill hole measurement data relate.
  • long-wave and short-wave trends can be discerned in this integrated image. These trends constitute identifiable information for an expert on the terrain here at issue, and provide a clear indication of its geological profile.
