Description
Technical field
The utility model belongs to a kind of tube type rheometer, is suitable for measuring the rheological parameter of viscous fluid, thixotropic fluid, and the rheological robotization that is particularly suitable for on-the-spot drilling fluid detects.
Background technology
Guan Liufa is a kind of common method of rheological measurement, and the principle of this method is a hage oiseuillelaw, and promptly the liquid of certain volume is proportional to the viscosity of laminar flow through given kapillary required time under the certain pressure gradient.Therefore, through measure flow rate of liquid and flow of liquid through the pressure differential of kapillary generation get final product liquid viscosity.The capillary viscosimeter manufacturing is simple, and price is lower, and temperature control is simple, and convenient experimental operation can be carried out the absolute measurement of viscosity, so capillary tube technique is a kind of attractive measuring method, has produced a large amount of patents.
1991, patent CN2085960 once proposed the rheological that a kind of capillary rheometer is used for measuring drilling fluid, it is characterized in that: the differential pressure measurement system is made up of slit kapillary and a pressure transducer that is installed on this kapillary wall.Though the indoor mud precision of this apparatus measures is higher; But the tracting pressuring hole of this instrument pressure transducer is thinner, has only 0.5～1mm; So when being used for the thixotropic fluid of thickness, cause the inaccurate problem of the excessive pressure survey that causes of particle plugging pressure tap or gel strength easily.
2002, the capillary viscosimeter that patent G01N11/06 proposes, this capillary viscosimeter mainly is used for measuring kinematic viscosity, be difficult to the automatic measurement of drilling fluid rheology, and traditional capillary viscosimeter is stopped up by small particle easily.
In order to overcome above-mentioned defective, the utility model provides a kind of tubular type drilling fluid rheology appearance.The utility model compared with prior art has following advantage: easy and simple to handle, stability of instrument is good, and data are reliable, is applicable to the rheological automatic measurement of on-the-spot drilling fluid.
Summary of the invention
Existing tube type rheometer exists the pressure measuring instruments tracting pressuring hole easily by the shortcoming of particle or viscous fluid obstruction, is difficult to on-the-spot drilling fluid rheology automatic measurement.The purpose of the utility model is for on-the-spot drilling fluid measurement a kind of novel pipe flow graph to be provided.
The technical scheme that the utility model adopted is: with pipeline drilling fluid container, crossing current pump, surge tank, flowmeter and kapillary are connected successively; Utilization flushes the usual pressure sensor that membrane pressure sensor replaces thin tracting pressuring hole, is installed on the tube wall capillaceous; Next is that to utilize section be that to replace section be the common kapillary of circle for the special-shaped kapillary of two flat oval rings between the flat oval; Annular space between the flat oval pipe is 2.75mm; The side plane width of flat oval pipe is more than or equal to the major diameter of thread that flushes membrane pressure sensor; The pressure transducer membrane plane is concordant with outer flat oval pipe inner side plane, and pressure transducer I and pressure transducer II are installed in respectively apart from the tube wall more than the 10cm of kapillary two ends.Adopt infinitely great parallel-plate rheology computing formula calculated flow variable element.
The tube type rheometer that the utility model provided is mainly by constant flow pump, surge tank, special-shaped kapillary, planar film pressure transducer, Coriolis flowmeter, automatic control system, compositions such as data acquisition and data handling system.Through the flow of automatic adjustment constant flow pump, can measure fluid automatically at 1020s
-1, 510s
-1, 340s
-1, 170s
-1Shearing stress value under the shear rate, the last rheological parameter that calculates fluid by data handling system.The flow graph measurement range that the utility model relates to is between 1.0mPas～100.0mPas, and measuring error is less than 3%.
The utility model has the advantages that: this utility model is applicable to the automatic measurement of realizing the drilling fluid rheology parameter, and the stability of instrument is high with degree of accuracy, and the robotization of property of drilling fluid in the drilling well production run is controlled and regulated significant.
