Description

Integral type blade fluid power-Magnetic drive borehole cleaning tool
Technical field
The present invention relates in petroleum and natural gas well drilling process, in order to effectively suppress cutting bed to be formed, improve the borehole cleaning tool that well cleaning efficiency is used, be specifically related to integral type blade fluid power-Magnetic drive borehole cleaning tool.
Background technology
Offshore oil natural gas, shale gas exploitation at present improves well drainage area frequently with well type such as high angle hole, horizontal well, extended reach wells, improves well yield to greatest extent.Owing to there is inclination section (hole angle is increased to the curved portion of 90 ° by 0 °) and net horizontal section in these well type, landwaste is not easy to be carried out in time by drilling fluid well under the effect of weight component, the phenomenon of talus deposit occurs, form cutting bed, field experience and indoor theory experiment and all show that cutting bed is prone between high angle hole section (referring generally to the inclination section between 45 ~ 90 °) and net horizontal section (hole angle 90 °) be formed.If drift bed thickness is too high in well, a series of serious down-hole problem will be caused, as drilling tool frictional resistance, moment of torsion increase, even there is serious down-hole accident such as bit freezing, twist off drilling tool etc., process these down-hole accidents and rate of penetration will be greatly lowered, increase considerably nonproductive time and operating cost.This just requires in the drilling process of this kind of well type, keeps higher well landwaste cleaning efficiency, and the well section being easily formed at cutting bed uses necessary method, prevents the formation of cutting bed, it is ensured that drilling tool and well safety.
The problem that there is landwaste cleaning difficulty for current High angle and horizontal segment, the commonly used following five kinds of methods cleaning well landwaste of situ of drilling well, including: improve drilling fluid and return speed, improve drilling fluid rheology performance, short trip tool, raising rod rotation speed and use the borehole cleaning tool of drilling rod transmission moment of torsion.
1, improve drilling fluid and return speed
In bore hole annulus, the average upward velocity of drilling fluid is the highest, is more conducive to removing landwaste.But it is high to the requirement of drilling equipment that height returns speed, and corresponding power cost is the highest.Simultaneously for some broken ground, height returns speed and is likely to result in serious cave-in accident.Therefore, being limited by equipment and stratum, raising is returned speed and can not be fully solved well cleaning problems.
2, drilling fluid rheology performance is improved
The method, by reducing the liquidity index of mud, improves ratio of dynamic shear force/yield value to plastic viscosity, improves drilling fluid and take lithology energy, strengthen its suspension carrying capacity.The shortcoming of the method is to improve property of drilling fluid to need the extra drilling fluid additive that adds, increase cost, and the highest ratio of dynamic shear force/yield value to plastic viscosity also can bring bigger burden to landscape apparatus such as pumps, increase power consumption.It is limited that the method is used alone the effect often played, and must coordinate other method.
3, short trip tool
Under existence conditions, improve mud and return speed except using and improve mud property in addition to improving its large rock-carrying ability, actual well drilled also needs coordinate the measures such as short trip, stages cycle and back reaming, to destroy, Cutting Disposal.Therefore, well section not serious for cutting bed deposition, the way of short trip can be used.The well type being easily formed cutting bed and well section, during short trip, the following drilling tool of kickoff point (KOP) moves along the lower borehole wall, can destroy cutting bed.More serious to cutting bed ratio, use the well of short trip DeGrain, the way of back reaming can be used to destroy cutting bed.Though using the short removing method that removes can play and consider clearly effect to be worth doing, to take a lot of time on making a trip, having had a strong impact on the efficiency of drilling well.
4, rod rotation speed is improved
Drilling process improves rod rotation speed and can improve the drilling fluid circumferential speed of drilling rod near surface, make landwaste preferably be suspended into well flash, improve the cleaning efficiency of landwaste to a certain extent.But when beating inclination section (hole angle 0-90 °) of landwaste cleaning difficulty, domestic and international commonly used mud motor (helicoid hydraulic motor and turbodrill) slipping drilling deflecting, for keeping hole azimuth angle constant, drilling rod and include that the housing of mud motor does not rotates, the most only bit breaks rock.But owing to drilling rod entirety does not rotates, it is impossible to use the method Cutting Disposal improving drilling rod speed.
5, the borehole cleaning tool of drilling rod transmission moment of torsion is used
The another kind of method that suppression high angle hole section and net horizontal section cutting bed are formed is to use blade-carrying landwaste burnisher, this instrument and drilling rod pass through screwed connection, drilling rod delivers torque to borehole cleaning tool while rotating, landwaste burnisher rotates with drilling rod and suppresses cutting bed, but shortcoming is instrument rotary power comes from drilling rod, when making inclination section application mud motor (turbodrill, helicoid hydraulic motor) when carrying out slipping drilling, owing to drilling rod does not rotates, the type instrument also cannot realize rotating, and does not the most suppress the effect that cutting bed is formed.
Summary of the invention
It is an object of the invention to provide integral type blade fluid power-Magnetic drive borehole cleaning tool, it is bad that this integral type blade fluid power-Magnetic drive borehole cleaning tool is used for solving well landwaste cleaning effect during the well type slipping drilling such as current high angle hole, horizontal well, extended reach well, it is impossible to the problem that suppression cutting bed is formed effectively.
