中原油田采油三厂文明寨油田、卫城油田、马寨油田自1982～1989年陆续投入注水开发以来,由于强注、强采,储层的孔隙结构发生了很大变化,目前有的地层渗透率已高达62030×10~(03)μm~2,孔道半径50.2μm。大孔道的存在,不仅造成油井过早水淹,而且还造成死油区存在及油层注水波及体积减小,严重影响了油田开发效果。为进一步提高调剖效果,降低成本,该厂利用造纸废液,研制出了调驱结合的纸浆废液调剖剂。该调
The Wenmingzhai Oilfield, the Weicheng Oilfield and the Mazhai Oilfield of the Third Oil Production Plant of Zhongyuan Oilfield have undergone significant injection and strong mining since 1982 ~ 1989, and the pore structure of the reservoir has undergone great changes. At present, The rate has been as high as 62030 × 10 ~ (03) μm ~ 2, the radius of the hole is 50.2μm. The existence of large channels not only causes the premature flooding of oil wells, but also causes the existence of dead oil zones and the influx and volume reduction of oil-injected reservoirs, seriously affecting the oilfield development effect. In order to further improve the profile control effect and reduce costs, the factory made use of waste papermaking fluid to develop a pulp waste control agent. The tune
