Abstract
The utility model discloses a petroleum well-drilling liquid density and viscosity determining device, which is characterized in that the utility model utilizes a funnel-shaped measuring cylinder. A pressure sensor is fixed on the cylinder wall at the lower part of the measuring cylinder. A blocking head connected with an electromagnetic valve is arranged on the release outlet at the bottom of the measuring cylinder. The utility model provides a device which can measure both the density and the viscosity of the petroleum well-drilling liquid. The utility model has the advantages of simple structure and convenient operation. The utility model is particularly suitable for the site test of the petroleum well-drilling engineering.
Description
The utility model relates to fluid density, viscosimeter, more particularly, is a kind of device that is applicable to petroleum drilling engineering on-site measurement drilling fluid density and viscosity.
In the petroleum drilling engineering, usually need the density and the viscosity of on-site measurement drilling fluid.At present, in the Process of Oil Well Drilling, all adopt artificial hydrometer method at home---the mechanical lever principle, measure drilling fluid density; Measure viscosity and then use the funnel method, be that stopwatch reads in the funnel quantitatively releasing the time of drilling fluid, as seen, the mensuration of density and viscosity is with two kinds of methods, and has device separately independently to carry out, and not only efficient is low for this mensuration mode, and, with operator's difference, have very big human error, influence the accuracy of measurement result.Comparatively Xian Jin assay method is under laboratory condition, adopts vibrating tube to measure fluid density; With rotary viscosity design determining viscosity, though the degree of accuracy of this mode measurement result is improved, be the mensuration of finishing two indexs by two devices respectively equally, and apparatus expensive, be not suitable for the oil field in-site measurement.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part, a kind of simple determinator is provided, but this device dual-use material, promptly finish the mensuration of tested drilling fluid density and viscosity simultaneously, when guaranteeing test accuracy, simplified structure, reduce cost, raise the efficiency.
The purpose of this utility model is realized by following technical scheme.
The utility model adopts funnel-form to measure tube, and fixation pressure sensor on the bottom barrel of measuring tube is measured on the tube bottom bleed outlet plug is set, plug and electromagnetic valve interlock.
Compared with the prior art, obvious advantage of the present utility model is a dual-use material, and a device both can solve the mensuration of density, also can finish the mensuration of viscosity, greatly facilitates the operator.The utility model can carry out complete machine and controls automatically by single-chip microcomputer is set, and calculates measured value, and therefore, no matter be finding speed, or the degree of accuracy of its test result all improves a lot.Of the present utility model be also advantageous in that simple in structure, cost is low, can adapt to various test environments, especially carries out on-the-spot test in drilling engineering.The utility model also can be applicable to other industry simultaneously, as chemical industry, pharmacy, food etc.
Accompanying drawing is the utility model structural representation.
In conjunction with the accompanying drawings the utility model is further described by the following examples.
Embodiment:
Referring to accompanying drawing, funnel-form measurement tube 1 adopts a stainless steel to make, and on the barrel of its underpart, fixation pressure sensor 2 adopts high-precision pressure sensor, on the bottom bleed outlet 3 of measurement tube 1 plug 9 is set, plug 9 and electromagnetic valve 5 interlocks.Be provided with slush pump 6 in the present embodiment, the input port of slush pump 6 is communicated with drainage tube 7, and its delivery outlet is communicated with measurement tube 1 by connecting leg 8.Support bar 4 makes it keep balance in order to fixation measuring tube 1 among the figure.
The course of work is as follows: the height of 1, measuring tube 1 is a determined value.Shut electromagnetic valve 5, open slush pump 6, mud is filled with measured tube 1, take out the pressure signal on the pressure sensor 2, according to formula P=h * d, wherein P is that pressure, h are that liquid depth, d are fluid density, thereby draws fluid density d=P/h.2, shut slush pump 6, open electromagnetic valve 5, plug 9 pine thereupon is stifled, mud is released from the funnel bleed outlet 3 of measuring tube 1, monitoring pressure sensor 2 pressure values change, and judge that a certain amount of mud releases the required time from bleed outlet 3, calculate the apparent viscosity of mud then.
Claims (2)
