摘要
以铵法造纸的纸浆废液为原料,利用固相堵塞、液相驱油的原理,在中原石油勘探局文明寨高含水小断块油田上进行了注入井调剖工艺研究,并已在现场试验了51井次。结果表明,纸浆废液调剖剂适合文明寨油田次生大孔道调剖。截止1995年12月,平均单井增油310t,含水率下降3.6%,动液面下降120m,累计增油32100t,降低产水量113750m3。
technology is researched for using spent pulping liquor after ammonia process of paper making as an agent for profile control in waterflooding the Wenmingzhai oilfield, a small faulted block field in the Zhongyuan area. It is based on the solid-phase plugging and liquid-phase displacement. The results obtained from 51 wells show that the spent pulping liquor with both shut-off and displacement functions is suitable to profile control for secondary pore passages in a reservoir.
