中原油田为实现天然气产量稳中有升,近几年加大了已开发气藏(田) 的研究力度。本文对东濮凹陷卫城构造卫11 块Es₃ ^下1-3 气藏开展了精细描述,完成了内部小断层解释、小层精细划分,以小层为单元开展了储层与流体分布特征研究及天然气储量评价,利用Earthvision 计算机建模技术建立三维可视化地质模型,深化了气藏地质认识,为精细评价储量动用状况和气藏开发潜力奠定了基础,在气藏开发调整中取得了好的效果。

In order to realize stabilization and promotion of gas production, The study on developed gas reservoirs has paid more attention in Zhongyuan Oilfield in recent years. A fine description of gas reservoir on Lower 1-3 member of Es3 in Weicheng block 11 in Dongpu depression has been conducted in this paper. The inner small fault s are interpreted and sublayers are divided also. Studies on fluid distribution features and gas reserve evaluation are developed. A 3D visualized geologic model are established with the technology of earthvision software on computer. Recognition of the gas reservoir is promoted. The study lays foundation for fine evaluation on gas reserve developing status and the potential of gas reservoir development. A good result has been achieved in development adjustment of gas reservoir.
