    摘要: Low-cost and easily-operated microviscometer suitable for medical diagnosis clinical studies and other fluid tests. The equipment consists of a microchannel (2) formed by concatenated microchannels made by micro-manufacturing techniques, and a fluid column position detector inside the microchannel. The microchannels are open at one end and closed at the other end and are made of a single biocompatible material. When a liquid drop is put into the inlet of the microchannel (2), the fluid enters by capillary until the compressed air pressure equals the capillary pressure plus atmospheric pressure. The fluid transient movement from entering the channel until stopping at its balance position is analyzed thus obtaining as a result the viscosity and the capillary pressure of the liquid tested.

    摘要: Computer-implemented methods, software, and systems for determining a property of a wellbore fluid are disclosed. In some implementations, a computing system receives an image of a first sample of the wellbore fluid filling a conduit to a threshold volume of the conduit. The computing system determines a first time duration of the first sample of the wellbore fluid filling the conduit to the threshold volume of the conduit based on the image of the first sample. The computing system receives an image of a second sample of the wellbore fluid filling the conduit to the threshold volume of the conduit. The computing system determines a second time duration of the second sample of the wellbore fluid filling the conduit to the threshold volume of the conduit based on the image of the second sample. A property of the wellbore fluid is determined based on a difference between the first and second time durations.

    摘要: Controlling a well injection operation, such as a well fracturing operation, includes identifying a flow characteristic of a fracturing fluid, identifying a flow characteristic of a base fluid used for forming the fracturing fluid, determining an amount of friction reduction change of the fracturing fluid, and adjusting the amount of friction reduction of the fracturing fluid to coincide with a selected friction reduction amount. Identifying a flow characteristic may be performed by a rheology measuring device including a measurement tube, a first pressure sensor disposed at a first position on the measurement tube, a second pressure sensor disposed at a second position on the measurement tube, a flow meter disposed at a third position along the measurement tube, a temperature sensor disposed at a fourth location along the measurement tube, and a control unit interconnected to the first and second pressure sensors, the flow meter, and the temperature sensor.

    摘要: The present invention relates to an apparatus (100) suitable for use in substantially continuous measurement of a physical property particularly the rheology and/or viscosity of a drilling fluid in use thereof in a drilling fluid or mud flow circuit of a drilling device. The present invention also relates to an apparatus (100) suitable for use in substantially continuous measurement of a physical property particularly the rheology and/or viscosity of any non-newtonian fluid is use thereof. The apparatus (100) comprises of a sample chamber (26) having an inlet (7) and an outlet (9) and is arranged to allow a drilling fluid to flow therethrough from the inlet 7 to the outlet (9). Detector devices (33, 34, 35) such as Viscometers are provided for substantially continuous measurement of a physical property particularly the rheology and/or viscosity of a drilling fluid flowing thought the sample chamber (26) in use of the apparatus (100). The sample chamber (26) has different diameters and has different flow rates and/or shear rates and will thus have different viscosities in a non-newtonian fluid which will be measured by a separate device such as a viscometer. Supply and return conduits are provided for connection of the inlet (7) and outlet (9) respectively in use of the apparatus (100) to a drilling fluid flow for delivering at least part of the drilling fluid flow through the apparatus (100) for measurement. A pump (18) produces a controlled flow of the diverted drilling fluid though the sample chamber (26) of the apparatus (100) so that the properties of the drilling fluid, particularly the rheology and/or viscosity can be measured on a more less continuous basis. A desirable backpressure in the sample chamber is controlled by a valve (8) on the outlet (9). The measurements of the separate devices (10) such as a viscometer can be used with other instruments to create a rheological model of the mud. The electrical signal generated by the viscometers (33, 34, 35) are sent for processing to a PC (12) and a device such as a chart and/or a data recorder (13). The direction of flow through the sample chamber (38) is shown by the arrows (39).

    摘要: An apparatus and method are disclosed for accurately determining viscosity of Newtonian and non-Newtonian fluids in the field or in-service by using a potable field viscometer. The portable field viscometer includes a vertical disposable (or reusable) sample insert tube filled with the liquid which the viscosity is to be determined. Using fins on the needle surface, a needle having a known density is made to fall through the liquid in the disposable (or reusable) sample insert tube coaxially. Using the time that the needle takes to fall between two known distance marks on the extension bar attached the top of the needle or transducers such as light, laser or magnetic, the velocity of the needle falling through the liquid is determined. Thus, the viscosity can be calculated by using the velocity of a needle. In the method, viscosity, shear rate and shear stress can be determined according to the disclosed method.
