摘要
为解决现场压裂施工中植物胶类压裂液腐败变质问题，研制了新型杀菌剂ＣＯＧ－２８５。该剂具有杀菌效果好，用量少，价格低，保质时间长，与压裂液化学添加剂配伍性好，配制、使用简便等特点，已在长庆油田投入现场应用。本文讨论了植物胶的腐败变质，报导了ＣＯＧ－２８５的研制及性能评价结果。
A bactericide, COG 285, is developed and put into use in Changqing Oil Fields for protecting plant gum based hydrofracturing fluids from fermentation and deterioration. It is a stabilized solution of a heterocyclic compound in 2% concentration. With 0.03% COG 285 added the aqueous plant gum solutions maintain more than 47%, 15%, and 22% initial viscosities after three days exposure at 35℃ in container, at 35℃ with deteriorated fluid added, and at 40-50℃ under infrared radiation, respectively. The inhibitory efficiency of COG 285 is similar to or better than Halliburtons BE 4. All the properties of the fluids with COG 285 are in acceptible ranges.
