Embodiment Construction

[0032] A preferred embodiment of the well-seismic combined sedimentary cycle matching analysis method of the present invention is as follows:

[0033] a. Load the logging data and the corresponding well bypass seismic data as the initial data for sedimentary cycle matching analysis; select a time-depth relationship to convert the logging data to the time domain, and re-log the logging data according to the sampling rate of the well bypass seismic data sampling. The specific steps are as follows: first, take the start time of the earthquake as the start point, search for the corresponding depth point closest to the point, and use the curve value corresponding to the depth point as the start point of the well data, search for the start time in sequence according to the seismic sampling rate, And record the curve value of the corresponding depth point until the resampling of the well curve is completed.

[0034] b. The analysis curves of different frequency ranges are obtained b...

Abstract

The invention provides a well-to-seismic integration sedimentary cycle matching analysis method, and belongs to the field of geophysical exploration seismic interpretation and comprehensive research. The method comprises the steps: obtaining seismic and logging data with the same sampling rate through data preprocessing; respectively processing the seismic and logging data through employing an EMD (Empirical Mode Decomposition) method based on the above; obtaining decomposition curves of different frequency spectrum ranges; carrying out the correlation analysis of the decomposition curves; adjusting optimization correlation through seismic phase rotation; and finally obtaining a more satisfactory matching result. The method can solve a problem of stratum integration comparison of data in different scales, and can be used for well-to-seismic integration stratum comparison and other exploration integration research.

Description

technical field [0001] The invention belongs to the field of geophysical prospecting seismic data interpretation and comprehensive research, and in particular relates to a sedimentary cycle matching analysis method combined with well and seismic. Background technique [0002] Cycle is a term used in stratigraphy and sedimentology to denote significant or periodic sedimentary records, with both descriptive and explanatory meanings. The cyclicity of stratigraphic records is due to the difference in sedimentation, depositional environment or driving mechanism. Stratigraphic cycles are usually divided into two types: spin cycles and other cycles. The spin cycle is mainly caused by the environmental cycle, which is localized and regional, such as the stratigraphic cycle formed by the lateral migration of river channels and delta lobes. Its cycles are usually caused by driving mechanisms other than environmental cycle factors, and have large-scale, cross-regional, and even global...
