Abstract
The present invention is a kind of device of telemeasurement rheologic property of liquid.This installs and adopts the control of singlechip microcomputer system, has realized that flow of liquid sex change remote measurement is controlled automatically and data are handled automatically.This device adopts buoyancy aid and balance device, and the measure portion control circuit is placed aluminium casting seal casinghousing, makes measure portion directly place the on-the-spot detected fluid groove that flows; Solved the automatic acquisition problems of on-the-spot detected fluid rheological parameter therebetween with wired mode transmission information.
Description
The present invention relates to a kind of device of measuring rheologic property of liquid, be specially adapted to measure the drilling fluid rheology performance, belong to the liquid viscosity measuring field.
The at present domestic and international used measurement drilling fluid rheology instrument of situ of drilling well, the overwhelming majority is the Fann35SA type rotational viscosimeter that U.S. FannShi instrument company produces.On-the-spot at present being of using of China imitated beautiful FannShi rotational viscosimeter.The subject matter that this instrument exists is:
1) can not directly measure the rheological parameter of actual cycle mud in the drilling process, and must adopt outdoor sampling, indoor measurement makes measurement can not in time reflect drilling fluid rheology characteristic in the well.
2) can not carry out the automatic control of measurement instrument, increase the randomness of measuring, reduce the reliability of measurement data.
3) rheological parameter can not be gathered automatically, cause the multiparameter instrument of present situ of drilling well all to lack this significant data of rheological parameter.
Purpose of the present invention is to overcome three problems that above U.S. Fann rotational viscosimeter exists, so that measure the actual well drilled liquid rheological property in the slush-pit launder timely and accurately, the safety that guarantees drilling well work is with rapid.
Purpose of the present invention can reach by following measure:
1) because of adopting advanced single-chip microcomputer MCS-8098 computing machine to come control survey part and control section, an interface of computing machine links to each other with stepper motor pulse distribution power amplifier, and another interface links to each other with code-wheel decoding input media circuit; FannShi viscosity meter rotating cylinder links to each other with stepper motor by gear, and FannShi viscosity meter rotor links to each other with increment type rotary coding dish device; The automatic collection that has solved on-the-spot action and rheological parameter of mud with wired mode transmission information between the measurement and control system.
2) because of with increment type rotary coding dish and supporting receiving system, directly be sealed in the aluminium casting seal casinghousing of measure portion, make in rugged environment still at a distance (more than the 100M) collection site data accurately.
3) adopt buoyancy aid and balance device, make measure portion directly place the on-the-spot drilling mud groove that flows.
Fig. 1 represents the basic composition of this device: it is made up of control section and measure portion (mechanical hook-up) (1).Control section by code-wheel decoding input media 2., stepper motor pulse distribution power amplifier driving circuit 3., the MCS-8098 computing machine 4., keyboard 5., display board 6., printer driver 7., mini-printer 8., 9. power supply form.4. high MCS-8098 computer system integrated, multi-functional, low-power consumption is control section and measure portion control core.5. receive user input instruction by keyboard, according to the 3. control step motor rotation of command request control step motor pulses power amplifier driving circuit, guarantee that flow graph rotates to set shear rate, 2. measure the shear stress that liquid produces by code-wheel decoding input media circuit.6. show motor revolution and shear stress values by display board then, or 7. control printer according to customer requirements through the printing drive circuit and 8. export mensuration and result of calculation.
Fig. 2 is the measure portion structural representation.(11) for connecting the cable of measure portion and control section, (12) be the cast aluminium seal casinghousing, (13) be increment type rotary coding dish, (14) be transmission gear, (15) be stepper motor (16) FannShi viscosity meter rotating cylinder, (17) be buoyancy aid, (18) are FannShi viscosity meter rotor, and (19) are detected fluid.Driving circuit control step motor (16) is put in the stepper motor pulse, and stepper motor drives flow graph rotating cylinder (16) through gear (14) and rotates to set shear rate.Viscous moment by fluid to be measured (19) drives rotor (18) rotation, thereby make the 4. machine processing calculating as calculated of Fann device circuit input computing machine, show motor revolution and shear stress values by display board then, or according to customer requirements printout mensuration and result of calculation.
The present invention has the following advantages
1) this device read value stabilization, reliable, precision is high, considers that simultaneously by step motor control rotating cylinder revolution, shear rate is provided with accurately, than 1.5 times of the minimum raisings of used Fann formula accuracy of instrument.
2) become computer control and measurement by hand-guided, range estimation, improved the repeatability of apparatus measures.
3) enlarged Instrumentation Operating Areas, accomplished a tractor serves several purposes, this machine has two speed, six speed simultaneously, the measurement function of flow graph also carries out measurement first, egress automatically continuously.
4) return out action and rheological parameter of mud by the measurement while drilling well head, can in time understand the down-hole situation, pre-well blowout preventing is played an important role.
The present invention is applicable to telemeasurement fluid rheology performances such as oil, chemical industry, papermaking, environmental protection.
