Abstract：Ultra-low abundance and thin oil layers have the characteristics of low reserves abundance, thin reserves and poor permeability. Horizontal well technology can effectively solve the problem in ultra-low abundance and thin layers. Horizontal injection pattern can increase the injection rate, reduce the injection pressure, maintain the reservoir pressure and improve the production efficiency. In view of these characteristics, we establish the geological model, design the basic horizontal injection-production well pattern, and select the typical pattern to perform analysis and evaluation. The dominant pattern is obtained, which can provide the basis for enhancing reservoir production levels using horizontal well pattern in ultra-low abundance and thin layers.
