大王庄油田留62断块二次调驱技术

SECONDARY PROFILE CONTROL BY COMBINATION FLOODING IN BLOCK LIU 62,DA WANG ZHUANG FIELD

    摘要
  • 摘要: 针对大王庄油田留62断块埋藏深、地层温度高、三大矛盾突出及多次小剂量调剖和一次大剂量复合调驱后,含水上升速度加快、油藏开发效果变差等问题,优选SDC、TC-938天然混合羧酸盐三元复合调驱剂进行整体二次调驱,取得较好增油降水效果,油藏采收率得到进一步提高。

     

    Abstract: There are many problems in Block Liu 62,such as deep burying depth,high temperature in stratum,severe inconsistency in or among layers and planes,rate of water cut increases quickly after many small dosages-profile control and one big dosage-combination flooding,so oil production effect was becoming inefficient.SDC,TC-938 as nature commixture carboxylate were optimized in the secondary whole combination flooding.After the flooding,the oil recovery was enhanced,water cut was going down,and better stimulation effect was obtained.
