氧活化测井技术在PL19-3油田开发中的应用

Application of oxygen activation log technology in PL19-3 Oilfield Development

油田在注水开发阶段,油层注入情况监测是重要的监测资料。氧活化测井技术多年以来在海上PL19-3油田得到大力推广和应用,针对油田水井分段注水、水嘴调配的注水方式总结出了测井选点标准、双参数深度校核以及适应海上平台作业的施工程序。PL19-3油田通过氧活化测井监测全井流量,可以校核水井流量进而对流量计进行标定。可以对水井封隔器进行验封,了解水井管外窜流状况。通过吸水剖面监测,PL19-3油田针对吸水不均井组,实施分层酸化、分层调配和调驱技术,增油控水效果显著,极大改善了纵向吸水不均衡现象。

Layer injection monitoring are important in the stage of water injection development.The oxygen activation logging technology widely popularized and applied for years in the PL19-3 oilfield.For the way of separated zonal water injection and injection nozzle allocation,summarizes the logging point selection standard,double parameters depth check,and the operation procedure in offshore platform.In PL19-3 oilfield,monitor the whole well flow through the oxygen activation log,calibrate flowmeter through checking the wellhead flow rate.Could test the packer sealing,understand the outside channeling condition.By monitoring the water injection profile,Zonal acidizing,zonal allocation and agent flooding have been implemented for the uneven injection profile patterns in PL19-3 oilfield.The effect of oil increasing and water controlling is significant,which greatly improves the unbalance of water injection profile.
