Application of Structural Properties of Seismic Data to Prediction of Hydrocarbon Distribution

2. Basic Principle

The waveform structure characteristic of seismic data is the waveform characteristics of the discrete data elements in the same time order in each seismic data, respectively, depended on the longitudinal temporal arrangement and transverse spatial combination changes. The relationship between amplitude, velocity or frequency of each seismic path and gray abnormal period is studied by using the gray model, and by gray correlation, the potential hydrocarbon region is predicted (Lin, Wang, Ma, Chen, & Fang, 2000; Brown, 1996).

The basic idea of oil and gas prediction and the method of oil and gas prediction are as follows: Through the gray topology method of mathematics, each seismic data in the seismic data volume is mapped to the data track similar to the logging curve, and then the calculation the vector correlation analysis is carried out. Finally, the location and plane distribution of the oil and gas stratum are predicted.
