该文的目的在于阐述完善气田开发方案的方法。静、动态描述相结合有助于优化气田的开发。文中列举了墨西哥一气田目前的主要理念、采用的方法和取得的成果。静态描述集中体现在三维地震解释建立起来的一系列地震振幅图上。动态资料包括生产数据和划分单储层、确定储层间水力连通性的初始压力梯度。根据动态数据对地震振幅图进行修改,可完善对储层性质的评价及对供气面积、原始天然气地质储量和探明地质储量的预算。综合应用测井、岩心、生产和压力数据对地震振幅图加以校正,便可设计最佳的油田开发策略。
The purpose of this paper is to explain how to improve the gas field development plan. The combination of static and dynamic description helps to optimize gas field development. The article lists the current main idea of a Mexican gas field, the methods used and the results achieved. Static description focuses on a series of seismic amplitude maps established by 3D seismic interpretation. Dynamic data include production data and individual reservoir stratification to determine the initial pressure gradient for hydraulic connectivity between reservoirs. According to the dynamic data, the seismic amplitude map can be modified to improve the evaluation of reservoir properties and the budget of gas supply area, original natural gas reserves and proven geological reserves. The combination of well logging, core, production, and pressure data corrects seismic amplitude maps to design the optimal field development strategy.
