Abstract: The main reservoir of lithologic gas reservoir of He 8 member of the Pernian Lower Shihezi Formation is multi-stage superimposed sand bodies in Su 14 well block of Sulige Gas field, which are deposited in braided river sedimentary system. The understanding of the superposition relationship of sand bodies is crucial, and how to formulate a reasonable working system is challenging for the efficient development of the gas field. By analyzing the superposition of sandstone reservoir of the gas field, the distribution relationship models between various types of production wells and superimposed sand bodies are established, and reasonable working systems are proposed for vertical wells and horizontal wells with different superposition models of sand bodies by numerical simulation method. The results show that the production of vertical well is mainly affected by the lateral superposition of sand bodies, and the vertical superposition of sand bodies has little effect; While for horizontal well, both vertical and lateral superposition of sand bodies have significant impact on the production;Sand body superposition is the main reason for the decline of gas production in the early stage of Sulige Gas field; The working system of intermittent production will better release the formation energy, delay gas well decline and play a good role in peak shaving. The study provides technical support for the efficient development of Sulige Gas field and achieves good application results, which can be used as a reference for the gas field development of similar type of reservoir.
