Description

一种高温高活性破胶剂
技术领域
本发明涉及石油化工技术领域，尤其涉及一种高温高活性破胶剂。
背景技术
常规酶破胶剂虽然在低温下是一种较好的压裂液破胶剂，但它要求较低的pH值。一般酶在pH=6 时活性最大，高温、高pH值会使酶失去活性。
发明内容
所要解决的技术问题是克服现有技术存在的缺陷，提供一种高温高活性破胶剂。
本发明所采用的技术解决方案是一种高温高活性破胶剂，包括纯净水和石蜡溶液，其特征在于：还加入了水溶性膳食纤维10-15份、聚乙烯吡咯烷酮1-5份，丁苯橡胶5-10份、明胶4-10份。
与现有技术相比，本发明所具有的有益效果为：本发明通过加入水溶性膳食纤维、聚乙烯吡咯烷酮，丁苯橡胶和明胶，使得该破胶剂具有很好的高温高活性能。
具体实施方式
本发明详细内容结合实施例加以说明：
实施例1: 一种高温高活性破胶剂，包括纯净水和石蜡溶液，其特征在于：还加入了水溶性膳食纤维10份、聚乙烯吡咯烷酮1份，丁苯橡胶5份、明胶4份。
实施例2: 一种高温高活性破胶剂，包括纯净水和石蜡溶液，其特征在于：还加入了水溶性膳食纤维11份、聚乙烯吡咯烷酮5份，丁苯橡胶8份、明胶6份。

Claims (2)

1.一种高温高活性破胶剂，包括纯净水和石蜡溶液，其特征在于：还加入了水溶性膳食纤维10-15份、聚乙烯吡咯烷酮1-5份，丁苯橡胶5-10份、明胶4-10份。
2.根据权利要求1所述的一种高温高活性破胶剂，其特征在于：其中聚乙烯吡咯烷酮1-1.5份。
