摘要(Abstract)：

针对聚驱转水驱后储层在平面和纵向上非均质性突出、注入水无效循环问题,提出了首先在油井堵水,然后在对应水井调剖的新工艺。数值模拟结果表明:在相同堵剂用量的条件下,可以大幅度提高油井的增油量和采收率;在保持水井调剖井距不变的条件下,逐渐增加油井反向调剖井距,采出井增油量和采收率会进一步提高;井组之间的连通性越好,增产效果越好。现场试验结果表明:井组平均综合含水率降幅达1.13百分点,8口油井累计降液10.3×10~4m~3、累计增油0.12×10~4t。
In the light of the problems of the serious horizontal and vertical heterogeneity for the reservoirs and noneffect cycle of trie injected water after the water flooding inverted from the polymer flooding,the new technology is developed i.e.first water shut-off in the oil wells and then profile control in the corresponding water wells.The numerical simulation result indicates that,on the condition of the same amount of the plugging agent,the incremental oil production and recovery factor of the oil wells can be increased significantly;under the condition of keeping the unchanged well spacing for the profile controlled water injectors,the corresponding spacings for the inverted profile-controlled oil producers are gradually increased,the incremental oil production and recovery are prone to be further enhanced;the better the connectivity among the well groups,the better the incremental effect will be.The field test results show that the average water cut has been reduced by 1.13%,the liquid production of 8 oil wells has accumulatively reduced by 10.3×10~4 m~3 whereas the accumulative incremental oil production is up to 0.12×10~4 t.
