研究了川东地区C2 hl气藏开采 2 0年全部投产井的静、动态资料 ,据气井的产能与地质参数和测井解释参数的关系的统计分析 ,提出了建立气井产能预测模型的技术思路和方法 ,建立了本区C2 hl气藏气井产能早期预测模型系统 ,完善和发展了碳酸盐岩裂缝—孔隙型气藏气井产能预测方法。该系统可以提供不同条件下新井在试采期及稳产期的产能 (即稳定产量的上限及下限 ) ,对于生产管理部门及决策者在选择开发井位、编制发展规划及地面工程预算有指导意义。
The static and dynamic data of all production wells in the exploitation of C2 h1 gas field in eastern Sichuan were studied. Based on the statistical analysis of the relationship between the production capacity of gas wells and the parameters of geological parameters and logging interpretation, the technical idea of establishing the gas well productivity prediction model And methods, an early prediction model system for gas well productivity in the C2 h1 gas reservoir is established, and a prediction method of gas well productivity in carbonate fractured-pore gas reservoirs is perfected and developed. The system can provide new wells in different conditions during the trial production and stable production capacity (ie, the upper and lower stable yield), for production management and decision makers in the choice of development wells, the preparation of development planning and ground engineering budget guidance .
