摘要:
井下乳化基质的流变特性对乳化基质长距离输送压力有很大影响。采用软固体测试流变仪对井下乳化基质在固定剪切率条件下进行了时变性测试，在变剪切率条件下进行了流型测试。测试数据和试验现象表明，乳化基质是一种触变性流体，其流动形态可以用HershalBulkley流变模型来表示，测得的井下乳化基质的本构方程为τ=247.59+56.93γ0.52 。在输送井下乳化基质时，可以通过提前进行不破坏其稳定性的低剪切率搅拌的方法降低输送压力。
Abstract:
The rheological properties of underground emulsion matrix have a great influence on the pressure of long distance transport of emulsion matrix. Soft solid test rheometer was used to test the timevaribility of underground emulsion matrix at a fixed shear rate and the flow of underground emulsion matrix at the variable shear rate conditions. Analysis of the test data of underground emulsion matrix and the experimental phenomenon shows that underground emulsion matrix is a kind of thixotropic fluid, and the flow patterns can be used to represent the HershalBulkley rheological model. The constitutive equation of underground emulsion matrix is τ=247.59+56.93γ0.52.In the delivery of underground emulsion matrix, the delivery pressure could be reduced by low shear rate of stirring method in advance without destroying the stability.
