Optimal Design and Research on Honeycomb-Like Structure Geothermal Production and Irrigation Well Network

Abstract

Inspired by the honeycomb shape structure, this structural shape was applied to the design of the geothermal well network, and the CMG simulation software with STARS as the core was used to establish a geothermal resource geological conceptual model of the Liaohe Oilfield Shenyang Oil Production Plant Oilfield. This model applied hydrothermal coupling simulation technology, studied the heat recovery effects of different production and irrigation well networks, conducted comparative analysis, and finally optimized the production and irrigation well network design and chose an inclined seven-point well network. The main advantages of using this honeycomb structure are reduced investment, maximum utilization of space, and larger Covers heat storage area to obtain maximum heat recovery, and it is easy to convert to other good network forms and adjust later.
