摘　　要：对比氧化剂降黏和生物酶降黏技术,提出以生物酶降黏技术为核心的压裂液余液无害化处理技术。处理后的余液可作为配制压裂液的用水。该技术已经成功用于现场。使用处理后压裂液余液配制的压裂液,经黏度和抗温抗剪切性能测试,满足现场使用要求。Compared with the viscosity-decreasing technology using the oxidant and the biological enzyme, a residual fracturing fluid harmless treatment technology with biological enzyme viscosity-decreasing technology as the core technology and post-treatment fracturing fluid as the fracking water is proposed. The technology has been successfully used in field. The fracturing fluid prepared by the residual fracturing fluid after treatment can meet the requirements of the site use, through the test of viscosity and the performance of temperature and shear resistance.
