摘要/Abstract

摘要： 克拉美丽火山岩凝析气藏资源丰富，但由于储层岩相多变，裂缝发育，边底水活跃，导致气井在开发过程中产水普遍。准确识别气井水侵规律、产水特征及产水模式，对于气藏新区开发及老区调整具有重要的参考价值。通过对克拉美丽典型气藏地质及开发资料进行综合分析，结果表明，常规的适用于裂缝型产水气藏水侵识别方法存在一定局限性，结合数值模拟技术更有利于认清产水规律；气藏水侵及产水特征曲线显示主要产水来源为边底水，严重影响气井产能；数值模拟研究结果将气井产水模式分为5类，通过统计分析将研究区典型气藏98口气井实际产水曲线定性划分为5类，得到模拟曲线与实际生产曲线分类结果基本吻合。基于数值模拟的产水模式划分结果可靠程度高，该研究结果为火山岩凝析气藏气井的部署开发与实时调控提供借鉴。

Abstract: Kelameili volcanic condensate gas reservoir is rich in resources, but due to the variable lithofacies, developed fracture and active edge and bottom water, the gas wells generally produce water in the process of development. Accurate identification of water invasion laws, water production characteristics and water production patterns of gas wells has important reference value for the development of new gas reservoirs and the adjustment of old gas reservoirs. Based on the comprehensive analysis of the geological and development data of typical gas reservoirs in Kelameili, we find that the conventional method suitable for water invasion identification of fractured water-producing gas reservoirs has some limitations, and the combination of numerical simulation technology is more beneficial to recognize the water production laws. The curves of water invasion and water production of gas reservoir show that the main source of water production are edge and bottom water, which seriously affect the gas well productivity. According to the results of numerical simulation, the water production modes of gas wells are divided into five categories. The actual water production curves of 98 gas wells in typical gas reservoirs in the study area are qualitatively divided into five categories by statistical analysis. The results of simulation curves are basically consistent with the actual production curves. The results of water production mode division based on numerical simulation are highly reliable, which can provide reference for the deployment and real-time control of gas wells in volcanic condensate gas reservoirs.

Key words: volcanic, condensate gas reservoir, numerical simulation, water-yielding laws, water-yielding patterns
