油气藏数值模拟技术在带油环凝析气藏开发中的应用

Application of reservoir numerical simulation for oil ring in condensate gas reservoir

近年来,如何高效开发凝析气藏尤其是带油环凝析气藏已成为国内油气田开发中的一个重要课题。以滩海某带油环凝析气藏为例,主要采用油气藏数值模拟技术对其合理井网井距、井型、水平井合理水平段长度、合理油气开发程序、油环注水效果及凝析气藏循环注气效果进行了计算分析,得出了具体的开发方案。

In recent years,highly efficient development of gas condensate reservoir especially gas with oil ringhas became a key topic in domestic oil and gas field development. This article taking the offshore oil ring condensation gas reservoir as an example, we mainly used the reservoir numerical simulation technology to analysis its reasonable pattern well spacing, well type,reasonable horizontal length of horizontal well,the reasonable oil gas development procedure,the oil ring irrigation effect and the effect of condensation gas reservoir circu- lation gas injection. The obtained conclusion laid a foundation for making reasonable development project of this condensate gas reservoir, and also provided a certain reference value for development similar to the condensate gas reservoir with oil ring.
