Description
Technical field
The present invention relates to a kind of solidification control system for well drilling liguid and control technique.
Background technology
Drilling Mud has become the important component part of modern oil/gas drilling engineering.A large amount of research data show that mud has carry and suspend landwaste, stabilizing borehole and equilibrium strata pressure, Cooling and Lubricator drill bit, drilling tool and transmission hydrodynamic force etc. and is directly connected to drilling cost in drilling process both at home and abroad, even have influence on the important function of drilling well success or failure.Drilling practice also proves, the quality of mud property, and whether use, maintenance and treatment measures are appropriate, directly affect the stability of the borehole wall, 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.Therefore, the mud property parameter is carried out real-time monitoring and just seem very important.
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.
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.
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.
