Abstract

The invention discloses an online rapid viscosity measuring device for a rock core displacement experiment under a high temperature and a high pressure. The device comprises a cylindrical housing (1) and a glass capillary (2) arranged in the housing (1), wherein one end of the glass capillary (2) is connected with a first pressure transducer (6), and the other end of the glass capillary (2) is connected with a second pressure transducer (7) and a mass flowmeter (8). The online rapid viscosity measuring device for the rock core displacement experiment under the high temperature and the high pressure uses the glass capillary to sample, and meanwhile measuring results can be rapidly displayed through a data calculating display unit, so that the measuring device need few samples and can rapidly and accurately measure in real time. During a process of a physical model test, monitoring point needed viscosity measuring can be randomly measured, and a seepage field inside the model can be maintained to be relatively stable, thereby providing an effectively technique means for dynamically analyzing viscosity fields of the physics models.

Description

technical field [0001] The invention relates to the technical field of reservoir fluid core displacement experiments, in particular to an online high-temperature and high-pressure rapid viscosity measurement device for core displacement experiments. Background technique [0002] In the research experiment of oil development and enhanced oil recovery, the core displacement experiment is an essential basic research method. The experimental physical model includes: one-dimensional, two-dimensional, and three-dimensional size models, wherein the one-dimensional model includes a 1-meter-long core and a 0.2cm-long short core; the two-dimensional model refers to the microscopic glass etching model; the three-dimensional model refers to the 50×50× 10cm sandstone slab model. Regardless of the material model, the viscosity data of the displacement fluid plays a vital role in the analysis of the viscosity field and fluidity field. If the viscosity data is to be obtained, the method o...
