摘　　要：渤海Z油田D7井组目前处于高含水阶段,对井间矛盾认识不清。为加深对该井组注采连通关系的认识及确定井间水窜通道参数等,在2018年对D7井进行了井间示踪剂监测。结果表明:D7井与D6井间存在水窜通道,水窜通道总体积为40066m^(3)。从2023年4月21日至2023年5月26日对D7井进行调剖作业,调剖作业结束后,D7井组日增油量26.4t,累增油量3779t。为进一步验证调剖作业的效果,尤其是调剖剂对高渗透层的封堵情况,在2023年7月21日再次对D7井进行示踪剂监测。结果表明:D7井与D6井的井间水窜通道的突进速率和体积均有较大幅度的降低,说明井间示踪监测技术在认识井间连通情况和解释水窜通道参数方面具有可靠性,可为调剖作业提供有价值的参考。The D7Well group in Bohai Z oilfield was currently in a high water cut stage,and the understanding of inter well contradictions was unclear.To deepen our understanding of the injection production connectivity of the well group and determine the parameters of inter well water channeling channels,inter well tracer monitoring was conducted on Well D7in 2018.The results indicated that there was a water breakthrough channel between Well D7 and Well D6,with a total volume of 40066m^(3).The D7Well was subjected to profile control operations from April 21,2023to May 26,2023.After the profile control,the daily oil increase of the D7Well group was 26.4tons,with a cumulative increase of 3779tons.To further verify the sealing effect of the profile control agent on the high permeability layer,tracer monitoring was conducted again on July 21,2023for Well D7.The results showed that the breakthrough speed and volume of the water channeling channel between Well D7and Well D6have been significantly decreased.The reliability of inter well tracing monitoring technology in understanding inter well connectivity and inverting water channeling channel parameters can provide valuable references for profile control operations.
