The sensor used for measuring the mud density and the mass flow rate is mainly composed of a sensor body (1), a sensor U-shaped tube (2) which is installed on the sensor body (1) and an electromagnetic position sensor (3) which is installed on the sensor U-shaped tube (2). A mud inlet (4) and a mud outlet (5) are formed in the sensor body (1), wherein the mud inlet (4) is communicated with the mud outlet (5). The sensor used for measuring the mud density and the mass flow rate is capable of quickly measuring the mud density and the mass flow rate, accurate in measuring result, simple in measuring procedure and capable of greatly lowering measuring cost. The sensor used for measuring the mud density and the mass flow rate supplies theoretical basis for the application of mud to drilling liquid.
Description
Technical field
The present invention relates to a kind of sensor for measuring mud density and mass flow.
Background technology
Drilling fluid refers to satisfy with its several functions in the oil/gas drilling process general name of the various circulation of fluids of drilling well need of work.Drilling fluid claims again drilling mud or referred to as mud (Muds), this paper with drilling fluid referred to as mud.Mud has the effects such as carry and suspend landwaste, stabilizing borehole and equilibrium strata pressure, Cooling and Lubricator drill bit, drilling tool and transmission hydrodynamic force in drilling process.
Nowadays Drilling Mud has become the important component part of oil/gas drilling engineering.Drilling practice shows, the quality of mud property is used, the maintenance measure appropriate direct stability that affects the borehole wall whether, and the stability of the borehole wall is related to admission, bit speed, quality and the cost of geologic information, so people often liken mud to the blood of drilling engineering.
Over nearly 40 years, indoor and industry spot experimental study proves in a large number both at home and abroad, and in the ordinary course of things, the solid concentration increase can cause the increase of density, viscosity, shear force, cake thickness and the sand content of mud, the decline of fluid loss.And the variation of these performances will obviously reduce drilling speed, increases the drill bit consumption, even might increase the situations such as leakage, gas cut, bit freezing, makes drilling cost significantly rise.
In the each task of oil exploration and oil field development, drilling well plays a very important role.In drilling process, the bottom rock rear landwaste that produces that is broken is carried on ground by circulating mud, and this process is called well-flushing.Well-flushing is to realize by circulating mud as the important step in drilling process, therefore there is the people mud to be likened to the blood of drilling engineering.
Mud refers to satisfy with its several functions in the oil/gas drilling process general name of the various circulation of fluids of drilling well need of work.The circulation of mud is kept by slush pump.The high-pressure slurry of discharging from slush pump through ground high pressure pipe joint, standpipe, hose, water tap, kelly bar, drilling rod, drill collar to drill bit, from the bit nozzle ejection, with bottom-hole cleaning and cutting carring.And then upwards flow along the annular space that drill string and the borehole wall (or sleeve pipe) form, flow into mud pit by discharge pipe arriving ground, then return to upper pool after various solid phase control appliances are processed, the Recycling of the most laggard people's slush pump.The various pipe fittings of slurry flows warp, equipment have consisted of a whole set of mud circulating system.
Drilling Mud is the important component part of modern oil/gas drilling engineering.Mud has the effect of the several respects such as carry and suspend landwaste, stabilizing borehole and equilibrium strata pressure, Cooling and Lubricator drill bit and drilling tool, transmission hydrodynamic force in drilling process.Drilling practice proves, the quality of mud property, whether use, maintenance and processing be proper, is directly connected to rate of penetration, bit life, down-hole problem, ground installation wearing and tearing, mud expense and the whole drilling well integrated cost of drilling well, even is related to the success or failure of drilling well.Therefore, necessary the mud property parameter is carried out real-time measurement, feedback, in order in time pinpoint the problems.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, a kind of sensor for measuring mud density and mass flow is provided, the sensor that should be used for measurement mud density and mass flow can be measured density and the mass flow of mud fast, and measurement result is accurate, measuring process is simple, greatly reduce the measurement cost, provide theoretical foundation for mud is applied to drilling fluid.
Purpose of the present invention is achieved through the following technical solutions: the sensor that is used for measuring mud density and mass flow, mainly by sensor body, be arranged on the sensor U-shaped pipe on sensor body and the Electromagnetic Position Sensor that is arranged on sensor U-shaped pipe consists of, be provided with the mud import and the mud outlet that communicate with each other on described sensor body.
The number of described U-shaped pipe is two.
Described U-shaped pipe is on sensor body and is arranged side by side.
Described Electromagnetic Position Sensor number is two.
Described Electromagnetic Position Sensor is symmetrical set on sensor U-shaped pipe.
Also be provided with hertz oscilltor on described sensor U-shaped pipe.
In sum, the invention has the beneficial effects as follows: can measure fast density and the mass flow of mud, and measurement result is accurate, measuring process is simple, greatly reduces the measurement cost, provides theoretical foundation for mud is applied to drilling fluid.
