Research on the Application of Excitation Well Depth Design Method Based on Fine Modeling of Surface Igneous Rocks in Hainan Region
摘要
There are three sets of igneous rocks developed in the Fushan Depression in Hainan, China. In particular, the distribution of surface igneous rocks is complex and varied. Due to the shielding of igneous rocks, multiple and scattered interferences, the data quality is poor, resulting in poor imaging under the rocks and difficulty in accurate structural interpretation. This article innovatively applies comprehensive information such as gravity and magnetism, transient electrical methods, micro logging, and lithological element analysis to jointly calibrate the distribution range and depth of surface igneous rocks, establish accurate models of the top and bottom interfaces and thickness structure of surface igneous rocks, and finely implement the spatial distribution of near surface igneous rocks. Targeted stimulation tests were conducted based on the surface igneous rock model, and the optimal stimulation well depth was selected. In the area of surface igneous rock development, the application of point by point excitation well depth design technology based on surface igneous rock models has improved the quality of collected data, and this method can be promoted in this area and similar places.
