龙岗礁滩气藏长兴组龙岗001-18井区数值模拟研究

Numerical simulation study on Longgang 001-18 wellblock of Changxing Formation of Longgang reef gas reservoir

龙岗礁滩气藏长兴组龙岗001-18井区气水关系复杂,高水气以及高产水量给气藏开发和气田水处理带来了较大困难.为了有针对性地治水,根据龙岗礁滩气藏长兴组001-18井区的地质模型,利用生产动态资料及相关资料,对气藏进行数值模拟研究,按照该气藏的合理生产规模设计了5套气田开发指标模拟预测方案,为气藏的合理开发提供依据.

Longgang 001-18 wellblock of Changxing Formation of Longgang reef gas reservoir has complex gas-water relation,and high water-to-gas ratio and high produced water make the development of gas reservoirs and the treatment of the produced water more difficult.In order to effectively control the produced water,on Longgang 001-18 wellblock of Changxing Formation of Longgang reef gas reservoir is studied according to production performance data and other related data by numerical simulation.Considering the reasonable scale of the gas reservoir production,5 sets of simulation prediction schemes are designed,which provids the basis for the rational development of the gas reservoir.
