Research and application of a new seismic data conversion method based on radian operation

With the continuous deepening of exploration and development, especially in the development stage, small-scale target bodies such as small fault blocks, small sand bodies, and hidden traps control the injection-production well pattern and the distribution of remaining oil in the oilfield, and have become the focus and goal of tapping the potential. Starting from the need to improve the accuracy of micro-amplitude structure interpretation, this paper converts the seismic data volume into a radian-domain data volume by calculating the slope and arctangent, which can effectively highlight the seismic reflection interface information, and the interpretation accuracy can reach 1 sampling point. Through the test application of actual data, the feasibility and reliability of the method in the interpretation of fine structure are confirmed, and it provides an effective method for identifying the micro-amplitude structure.
