摘要:

为了探究潜山裂缝气藏分段控水机制,以惠州26?6凝析气田为基础,通过实验参数设计、潜山裂缝地层设计和分段控水工艺设计,开展建立裂缝气藏控水物理实验模型、均衡气水界面和分段控水实验评价。研究表明,分段式控水可以有效延长无水采气期,一定程度上延缓了见水时间;不同产状的裂缝与水平井段组合不同,产气特征差异较大;水平井分段控水与气藏渗流作用是一个复杂耦合过程,盲管段与生产段匹配直接影响气井的产能,生产段打开程度、盲管段长度、盲管段位置是影响裂缝气藏产能的主要因素。研究成果旨在建立潜山气藏分段控水开发的模式,为合理科学的海上凝析气田水平井控水研究提供良好的技术支持。

Abstract:

In order to explore the water control mechanism of buried hill crack reservoir section, taking Huizhou 26?6 condensate field as an example,the fracture gas reservoir water control physical experiment model,equilibrium gas water interface and piecewise water control experiment evaluation were established,through designing the experimental parameters,buried hill crack formation and water control process.The results show that the segmented water control can effectively prolong the water?free gas production period and delay the water breakthrough time to a certain extent.The different combination of crack and horizontal well section would induce diverse gas production characteristics.Coupling between horizontal well subsection water control and gas reservoir seepage was a complex process.The matching between blind pipe section and production section directly affects the gas well productivity.The opening degree of production section,the length and the location of blind pipe section are the main factors affecting the productivity of fractured gas reservoir.The research results will establish a sublevel water control development model for buried hill gas reservoirs and provide good technical support for rational and scientific research on water control of horizontal wells in offshore condensate gas fields.
