Carbonate rock high-frequency sequence automatic identification method based on BP neural network

Abstract

The invention discloses a carbonate rock high-frequency sequence automatic identification method based on a BP neural network. The carbonate rock high-frequency sequence automatic identification method comprises the following steps of S1, establishing a high-frequency sequence identification and division standard database; and S2, compiling and debugging a BP neural network model based on python. By learning the sequence division standard of geologists with rich sequence division experience, the BP neural network with strong migration ability is established, problems of high sequence division difficulty and long period are effectively solved, automatic division of high-frequency sequences is realized, and the method can be used as an important means for understanding marine facies stratum sedimentary environment evolution and assisting in oil-gas exploration.

Description

Technical field [0001] The present invention belongs to the field of oil and gas exploration, and in particular, the present invention relates to a method of automated a carbonate high-frequency layer sequence automation recognition based on BP neural network. Background technique [0002] Sequence: "Sequence" This concept is of great guiding significance for oil and gas exploration. Since the 1980s, the four sequential land layers have emerged. The "Sequence" concept was earlier by Sloss and other scholars. In 1977, VAIL et al. Further established a classic sequential land layer with the sea plane lifting. Since then, the cause of the genera-sequencing part of Galloway. And the TR sequential layer layers represented by CROSS have been raised. Typically, high frequency sequence is generally considered to be a four-stage and subsequent higher levels of rotation. [0003] The conventional sequence of sequence is identified by the unconception surface or the corresponding integrated...

[0018] Although the sequence division schemes of Vail and Cross are different, the operation process requires a lot of manual operations. Therefore, the Cross school scheme has the same disadvantages as the Vail school scheme.
