摘要
WDS-2型杀菌剂是目前在中石化西南油气分公司广泛应用的压裂液杀菌剂,其效果良好,但在同一个区块长期使用同一类型的杀菌剂,微生物会产生抗药性。为此,研制出新型复合杀菌剂GCY-6,并对二者进行了详细的性能对比评价实验。200余个不同温度、不同浓度下基液粘度保留率数据表明,GCY-6性能略优于WDS-2;腐生菌的杀菌率评价实验结果表明,GCY-6的杀菌率在相同浓度下,明显优于WDS-2。且GCY-6合成的方法可靠、操作方便,具有工业化应用的价值。
At present,the fracturing fluid bactericide WDS—2 has been applied widely in the south-west oil and gas branch company,Sinopec. Although the preferable result has been gotten,micro- organism will produce negative chemotropism if the same type of bactericide used in the same district for a long time. Therefore the new compound bactericide GCY-6 has been prepared,furthermore the evaluation and contrast research on the performance properties experiments have been carried out between them. More than 200 data of the viscosity reserved rate for the basic fracturing fluid shows that the GCY-6 's performance is a little better than that of WDS-2. The disinfection rate of the TGB between them reveals that the GCY-6's performance is better than that of WDS-2 obviously. What’s more,the synthesis method for the GCY-6 is reliable,the operation is convenient. It is worth while to be applied in the oilfields.
