摘要
渤海某凝析气田地质情况复杂,采用衰竭方式开采,投产至今已持续生产近30年,累计产气达85×10^(8)m^(3),天然气采出程度已超过65%。目前气田已进入开发后期,因油水侵入导致气井产能大幅降低,同时,井身结构、生产流程环节频繁出现的异常情况也对安全生产带来较大隐患。通过深入分析该气田开发特征及生产管理中出现的问题,优化并制定了配套生产管理和采气工艺技术对策,可以有效地减缓油水干扰并延长气井寿命,对类似凝析气田的高效开发具有一定的借鉴意义。
The geological condition of a condensate gas field in Bohai Sea is complicated and it has been exploited by depletion mode for nearly 30 years,with a cumulative gas production of 85×10^(8)m^(3)and a natural gas recovery degree of more than 65%.At present,the gas field has entered the later stage of development,and the gas well productivity is greatly reduced due to oil-water invasion.Meantime,the frequent abnormalities in well structure and production process also bring great hidden dangers to safety production.Through in-depth analysis of the development characteristics and problems in production management of the gas field,the supporting production management and gas production process technical countermeasures are optimized and formulated,which can effectively reduce the oil-water interference and prolong the service life of the gas well,which has a reference significance for the efficient development of similar condensate gas fields.
