After decades of development of the Chinese petroleum industry, complex oil and gas reservoirs have become the main battlefield for oil and gas field detection and development, which pose severe challenges to geosteering drilling technology that uses integrated logging and conventional logging-while-drilling tools to locate and predict formation interfaces. Based on the developed software for the distribution of forward and lateral detection electromagnetic fields, this paper calculates and analyzes the distribution characteristics of electromagnetic fields at different distances in front, and studies the lateral detection characteristics based on the half-coil of the electric field. The results show that the influence of boundary on the field is revealed according to the distribution characteristics of electromagnetic fields at different distances in front. The 1-3m receiving-transmitting short-pitch half-coil have approximately the same edge detection distance, and when the frequency is less than 20 kHz, the edge detection distance is more than 30m in two beds formation of 0.01S/m and 1.0S/m.
