摘要
随着气田的不断开发,气藏的生产特征、流体渗流规律不断发生变化,地下的气水分布越来越复杂。为了进一步提高对气藏的认识,了解气藏流体流动状况及气藏物性参数,需要对气藏进行动态监测。以东胜气田实际监测的产气剖面、压力、流体等开发方面动态监测资料为基础,优选不同区块、不同层位生产气井为研究对象,结合气田实际生产情况,浅析开发动态监测资料在东胜气田开发中的应用。研究表明动态监测资料在东胜气田开发分析中应用普遍,常规的动态监测手段为分析气井各产层贡献情况、气藏压力保持水平、井筒流态变化规律、优化排采措施及预测动态可采储量等各项开发指标提供有效依据;对深化气藏认识、调整开发策略、制定下步开发方案有重要意义。
With the continuous development of gas fields,the production characteristics and fluid flow law of gas reservoirs are constantly changing,and the distribution of gas and water underground is becoming more and more complicated.In order to further improve the understanding of the gas reservoir,it is necessary to carry out dynamic monitoring of the gas reservoir to understand the fluid flow condition and the physical parameters of the gas reservoir.Based on the dynamic monitoring data of gas production profile,pressure,fluid and other development aspects of the Dongsheng Gasfield,selected production wells of different blocks and layers as research objects,the application of the dynamic monitoring data in the development of the Dongsheng Gasfield is analyzed in light of the actual production situation of the gas field.The study shows that dynamic monitoring data is commonly used in developing and analyzing the Dongsheng Gasfield.The conventional dynamic monitoring methods provide a practical basis for analyzing the contribution of each production layer of the gas wells,the reservoir pressure maintenance level,the change law of wellbore flow pattern,the optimization of drainage and production measures,the prediction of the dynamic recoverable reserves and other development indexes.It is significant to deepen the understanding of the gas reservoir,adjust the development strategy,and formulate the next development plan.
