Abstract
In order to study the internal cycle characteristics of glutenite reservoirs, this study conducted high-resolution sequence division of glutenite based on INPEFA technology and wavelet transform technology. In this paper, the basic principles of INPEFA technology and wavelet transform technology are introduced in detail, and the differences and advantages and disadvantages of the two methods in high-resolution sequence division are compared. Taking Jilantai oilfield as an example, combined with INPEFA technology and wavelet transform technology, INPEFA processing and wavelet processing are innovatively carried out based on acoustic time difference curve, and the accuracy is verified by each other. On this basis, combined with logging, seismic, lithology and other data, the top and bottom interfaces of the third-order sequence of the K1g1 in the study area were identified, and on this basis, K1g1 was further divided into two oil groups, a total of eight layers.
