Discussion on Key Technical Indicators for Performance Evaluation of Self-suspended Proppant
摘要
Abstract
The self-suspended proppant can reduce the settlement and improve the sand carrying capacity by increasing the viscosity when exposed to water,which has the technical advantages of improving the sand spreading profile.At present,according to the sectoral standard of the petroleum industry,Performance test method of proppants used in hydraulic fracturing and gravel-packing operations,its performance cannot be fully characterized,which brings difficulties to material evaluation and optimization.In this paper,the test method of the viscosity enhancement capacity of the suspension proppant is designed,the longitudinal upper and lower density ratios are proposed to define the suspension rate,and the relevant equipment and evaluation methods are developed,and the test results show that the applicability is good,which lays the foundation for product optimization and field application.关键词
