An Environmentally Friendly Non-foaming Anti-water Blocking Agent

  • 摘要: 为提高钻井液用防水锁剂的抑泡和环保性能,以海藻酸、羟乙基乙二胺(AEEA)、环氧氯丙烷(ECH)和季戊四醇(PETP)为原料,合成了一种天然改性产物作为防水锁剂SMFS-1。借助傅里叶红外光谱(FT-IR)仪进行了分子结构表征。防水锁性能测试结果显示,加入SMFS-1后水溶液的表面张力能够降低至25 mN/m以内,减小岩心自吸水体积,可促使岩石表面由亲水向中性转变,提高岩心渗透率恢复值至80%以上。SMFS-1抗温可达120 ℃,吸附性能优异,无起泡效应,对钻井液的流变性和滤失性能影响小。环保性能测试结果显示,SMFS-1的半致死浓度(EC50)为32 250 mg/L,生物降解性评价指标(Y)为17.36,达到排放标准,易被生物降解。
