摘要
储气库注采井注采能力是储气库工程设计中的关键参数,决定了储气库的最大应急调节能力,对已完钻的注采井开展准确的注采能力评价就显得尤为重要。针对相国寺储气库注采井大井斜角、长水平段、复杂注采管柱结构和强注强采等特点,开展动态监测技术适应性分析,优化连续油管动态监测工具及施工方案,并进行了2口注采井在高注气量条件下的连续油管动态测试现场施工作业,获取了动态监测数据。对现场施工工艺、配套工具及监测数据评价分析表明,连续油管动态监测技术可满足储气库注采井动态监测施工要求,录取的的数据真实可靠,能为注采井最大调峰能力的确定和注采井的调整提供充分的依据,对类似储气库注采井动态监测工作具有借鉴意义。
The injection-production capacity of injection-production wells for gas storage is a key parameter in the design of gas storage engineering and determines the maximum emergency regulating capacity of gas storage, so it is especially important to accu-rately evaluate the injection-production capacity of drilling injection-production wells. In view of large deviation angle, long horizontal section, complex injection and production string structure and forced injection and production for Xiangguosi Gas Storage, analysis was conducted to the suitability of dynamic monitoring technique, the coiled tubing dynamic monitoring tool and job scheme was optimized, and coiled tubing dynamic monitoring was conducted at site on two injection-production wells under high steam injection condition, and the dynamic monitoring data was obtained. Evaluation and analysis of ifeld operation technology, matching tools and monitoring data show that the coiled tubing dynamic monitoring technique can satisfy the dynamic monitoring operation for injection-production wells for gas storage, the obtained data is true and reliable, and the technique can provide sufifcient basis for determining the maximum peak load regulating capacity of injection-production wells and regulation of injection-production wells and is of reference signiifcance to the work of dynamic monitoring for gas storage injection-production wells.
