Description

一种页岩气新型环保滑溜水
技术领域
本发明涉及非常规油气田开采技术领域，特别涉及一种页岩气新型环保滑溜水。
背景技术
在非常规油气藏的勘探开发过程中，由于其储层的低孔、低渗特征，多数非常规油气储层都需要实施水力压裂才能达到工业开采价值，但是大量的压裂液伤害证实，常规的聚合物压裂液体系对基质的渗透率损害在30%以上，严重影响压裂的增产效果；并且对地下储层的伤害也很大。随着压裂液滤失，在支撑剂充填裂缝中，交联液体被浓缩了许多倍，被浓缩的交联聚合物如果在施工后没有降解或破胶后的残渣多，都对支撑裂缝的导流能力带来严重的伤害，尤其是对于非常规储层，达不到预期的增产效果；并且污染环境。
滑溜水不含高分子聚合物，对储层伤害小。对于非常规油气田来说，滑溜水压裂将是开采这类油气田的重要措施，也是降低采油成本，增加动用储量的有效途径。
发明内容
本发明提供一种页岩气新型环保滑溜水。它对非常规储层伤害小，具有较高的支撑剂裂缝导流能力，可以产生更长的有效裂缝；清洁环保无污染。同时该滑溜水压裂过程中，用极少量的支撑剂即可实现与聚合物压裂液相似的支撑剂充填效果。
本发明的技术方案为：
 一种页岩气新型环保滑溜水，由以下物质混合制备而成：
降阻剂           0.05%~0.15%；
助排剂          0.1%~0.3%；
杀菌剂          0.2%~0.5%；
粘土稳定剂    0.5%~1.5%；
余量为清水。
所述的降阻剂为聚丙烯酰胺乳液。
所述的助排剂为十六烷基三甲基氯化铵和脂肪醇的混合物。
所述的杀菌剂为氯化钠和丙烯醛的混合物。
所述的粘土稳定剂为氯化钾。
本发明的有益效果在于：对非常规储层伤害小，具有较高的支撑剂裂缝导流能力，可以产生更长的有效裂缝；对地下储层无伤害，清洁环保无污染。同时该滑溜水压裂过程中，用极少量的支撑剂即可实现与聚合物压裂液相似的支撑剂充填效果。
