滑溜水压裂液体系高温高压动态减阻评价系统

滑溜水压裂液体系是针对页岩气储层改造而发展起来的一种新的压裂液体系,减阻剂是滑溜水体系中的最关键助剂,其研究与应用日益增加。为了定量评价减阻剂的减阻效果,室内需要有效的模拟评价实验仪器,但目前的评价装置都无法模拟高温高压的储层条件。JHJZ-I高温高压动态减阻评价系统,就是为真实全面地评价各种储层条件下减阻剂的减阻效果而研制出的评价装置。该评价系统能在高温高压下对减阻剂的减阻效果进行评价。通过测算减阻剂的减阻率,从而优选出满足各种储层条件下的减阻剂。该评价系统功能强、效率和自动化程度高,可模拟高温高压条件下管道流体在不同剪切速率下流变性的研究,对减阻剂的研究和生产具有指导意义。

Evaluation System for Slick-water Fracturing Fluid Used in Shale Gas Well

Slick-water fracturing is becoming more widely accepted in shale gas well operation, and friction reducer is the critical additive in formulating this fracturing fluid. To quantitatively evaluate the performance of friction reducer in slick-water fracturing fluid, an evaluation device and a set of operational procedure need to be established. The JHFR-I evaluation system is such a system that has the advantage of HTHP operation over conventional evaluation systems. The highly automated JHFR-I is a full-function efficient system, which in rheological study can be used in simulating HTHP pipe flow at different shear rates. JHFR-I is highly helpful in the study and production of friction reducer.
