摘要：
Based on the abundant static and dynamic data of horizontal wells in Sulige gas field, we carried out the fine description and development dynamic response analysis of the effective reservoir of the actually drilled horizontal wells and put forward three effective reservoir spatial distribution modes, which were block concentrated development, medium thin layer superposition, and thin layer isolation. We established the reservoir classification standard for the deployment of horizontal wells. Based on the core indexes such as dynamic reserves, drainage area, initial reasonable production, and decline rate of horizontal wells, the quantitative identification and division standard of horizontal well development effect were also established. The dynamic reserves of horizontal wells in three types of reservoirs are more than 8 × 107m3, 6 × 107~ 8 × 107m3, less than 6 × 107m3, the initial outputs are 6 × 104, 4 × 104, and 2 × 104m3/d, and the initial decline rates are 32. 9%, 35. 0%, and 40. 0% respectively. The dynamic and static horizontal well development effect evaluation system established in this paper could support the optimal deployment of horizontal wells in Sulige gas field in the future. © 2023 China University of Mining and Technology.
