Abstract

Abstract:

The main and secondary fault zones in Shunbei and Tuoputai areas are the main fields of exploration and development evaluation. The faults play an important role in controlling reservoir, reservoir and wealth. It is of great significance to carry out research on the internal structural characteristics of the faults for the optimization of exploration targets and the evaluation of development potential. The reservoir types and physical characteristics of different internal structure of the fracture units are different from those of the original rocks, so there must be a corresponding reflection on the logging data. This makes it feasible to describe the internal structure of the fracture with various well logging data. Further exploration of the information contained in the logging data will be a “key” to understanding the internal structure of the fracture. By combining outcrop profile with seismic data, the internal structure of the fracture was qualitatively analyzed by making full use of conventional and imaging logging data in shunbei and Tuofutai blocks. It can be divided into four types of fracture structural units: fault core, crushed zone, fracture zone and dispersed fracture. And then the logging response characteristics of each structural unit in the fracture are summarized, and the identification standard of the structural unit in the fracture is established.

Key words: Shunsbei, Tuofutai, fault zone, internal structure, logging response
