Problems solved by technology

[0004] However, for the traditional Mie cycle dating technique, if there are sediments formed by sudden events in the sediments, it will cause large errors in the spectrum analysis results and filtering results
This led to certain errors in the dating of sediments (including event sediments)

Embodiment Construction

[0049] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings. Embodiment 1 of the present invention provides the basic flow of the dating method based on the logging Mie cycle analysis method, such as figure 2shown, including the following steps:

[0050] S201, obtaining sedimentation record data and corresponding depth values ​​of sediments at different depths in the target interval;

[0051] S202. Obtain core samples and depth values ​​of sediments at different depths in the target interval, and analyze the core samples to determine the depth of the incident sediments;

[0052] S203, removing the sedimentary record data at the depth of the incident sediment from the sedimentary record data, so as to obtain the data to be analyzed by spectrum and the depth value;

[0053] S204, matching the data to be analyzed and the depth value with the pre-acquired astronomical period, s...

Abstract

The invention relates to the field of petroleum geological exploration, in particular to a dating method based on a logging Mie cycle analysis method. The dating method based on the Mie cycle analysis method based on logging is based on the traditional Mie cycle analysis method, by judging whether the sediments at different depths in the target interval are event deposits, and then using the traditional The sedimentary record data and corresponding depth values ​​of sediments at different depths obtained by the Mie cycle analysis method contain the corresponding data of event deposition and corresponding depth values, and use the data and depth values ​​after removal to specify the depth The age of the sediments was estimated. In this way, the influence of sediment dating caused by event deposition is avoided, and the age of the measured sediment is more accurate.

Description

technical field [0001] The invention relates to the field of petroleum geological exploration, in particular to a dating method based on a logging Mie cycle analysis method. Background technique [0002] With the advancement of geological research to the quantitative direction, there is an urgent need to determine the age of sediments. The determination of sediment ages is of great significance for establishing the isochronous stratigraphic framework of basins and for oil and gas exploration. The determination of sediment age mainly includes isotope dating, zircon dating and traditional Milankovitch dating (traditional Mie cycle dating technique). [0003] The isotope dating method and zircon dating method used in the precise dating of ancient sediments are expensive in testing and have strict requirements on sample quality, that is, both methods are limited by samples and costs. Cannot be effectively used on a large scale. Another traditional Milankovitch cycle method for...
