复合离子型调剖剂性能及影响因素分析

The Capability and Affecting Factors of Compound-Ion Profile Control Agent

根据油田改善水驱和聚合物驱的实际需求和现有复合离子型调剖剂的不足,通过室内实验研究,提出了采用普通阴离子型聚合物作为主剂、有机和无机化学剂为交联剂的复合离子型调剖剂,并对调剖剂的性能及其影响因素进行了评价和分析。实验结果表明,与同类型调剖剂相比较,复合离子型调剖剂具有费用低、主剂来源广和对水质适应性强等特点,具有广泛的应用前景。

At the demand of improving the effect of water flooding and polymer flooding and the shortage of the current compound-ion profile control agent, based on the research from laboratory, we bring a new kind of compound-ion profile control agent, in which the common anion polymer is the main agent and the organic-compound and inorganic-compound is the crosslinker. The capability and affecting factors are also estimated and evaluated. The result shows that this new agent has the advantages of low cost, wide sources of the main agent and well adaptation to the water. It can be used widely in the future.
