摘要
Abstract
The carbonate reservoir of Permian Maokou Formation in the Sichuan Basin has strong heterogeneity,and its reservoir space is mainly cracks and holes.It is difficult to evaluate the fractures and caves near the borehole by conventional logging methods due to the limitation of detection depth.The conventional dipole acoustic reflection imaging can evaluate the fractures and caves in the range of several meters to tens of meters around the borehole to a certain extent,but it has the disadvantages of low resolution and 180° ambiguity in azimuth measurement.The 3D Far-field sonic service based on Sonic Scanner can simultaneously record multi-azimuth monopole and dipole wave field data.By combining the processing results of monopole and dipole data,the high-resolution detection results of the borehole-side structure can be obtained and the remote detection depth can be realized at the same time.The true azimuth and dip of the well-side structure can be obtained by using ray tracing and 3D-STC technology,which overcomes the limitations of traditional acoustic remote detection technology.This paper introduces the 3D Far-field sonic service technology and the field application case of a horizontal well in Maokou Formation in central Sichuan Basin.The field application results show that the technology can effectively evaluate the fractures and formation interfaces within 60 m near the borehole in the carbonate reservoir of Maokou Formation in central Sichuan Basin,which provides a strong technical guarantee for the increase of reserves and production in Maokou Formation.关键词
