Description
Technical field
The present invention relates to a kind of particle stabilized emulsion body and preparation method, relate in particular to a kind of particle stabilized emulsion body that is used for petroleum drilling engineering and preparation method thereof and application as lubricant for drilling fluid.
Background technology
In petroleum drilling engineering, drilling fluid is absolutely necessary.It can play the landwaste that carries and suspend, stabilizing borehole and equilibrium strata pressure, and cooling and lubricated drill bit, drilling tool transmit effects such as water power, and the quality of property of drilling fluid directly influences the wellbore quality and the drill speed of drilling well.And, give birth to bigger friction owing to understand this between drilling fluid and drill string and drilling rod and the brill wall, cause local heating's inequality, shorten the life-span of drilling rod and drill bit.
Along with applying of directed-drilling technique, especially horizontal well construction is more and more higher to the requirement that reduces frictional resistance, and the development of lubricant for drilling fluid and application have had rapid progress since the eighties.
Moment of torsion resistance that drill string rotating produces when boring perpendicular hole in the past and the friction resistance that makes a trip just can overcome with common drilling fluid, do not need to add in addition lubricant.But when using weighted drilling fluid, moment of torsion resistance and friction resistance then can not be ignored, and big more its resistance of drilling fluid density is also big more, will not cause bit freezing so do not add lubricant.
In orientation well and horizontal well construction, along with the increase of hole drift angle, the contact area of the drilling tool and the borehole wall and friction resistance and moment of torsion resistance increase thereupon.The factor that influences resistance has 10 kinds more than, but its size depends primarily on the contact area of the drilling tool and the borehole wall.There are three kinds of lubrication modes in the drilling process: obstacle lubrication mode, boundary lubrication pattern, hydrodynamic lubrication pattern.From reducing the angle of frictional resistance, avoid obstacle to lubricate, keep hydrodynamic lubrication as far as possible., should set about from drilling technology and drilling liquid technology two aspects for this reason: the first, reduce the contact area of the drilling tool and the borehole wall as far as possible; The second, improve the drilling fluid lubricating performance by adding examples of suitable lubricants.
Obviously, the contact area that reduces the drilling tool and the borehole wall in orientation well and horizontal well is impossible, and developing the high-efficient drilling fluid lubricant is the unique channel of dealing with problems.
At present, the requirement to lubricant in the drilling process is necessary energy lubricated metal surface, forms boundary film and secondary structure on its surface, little to the property of drilling fluid influence, do not reduce the rock failure performance, have higher thermostability, metal is not produced corrosion phenomenon, and environmental friendliness.So contemporary conventional lubricants comprises inert solid lubricant and mineral oil, vegetables oil and tensio-active agent etc.The lubricity of graphite powder is the highest in solid lubricant commonly used, and its elasticity is fine, does not influence drilling fluid rheology under high density, but its anti-shear ability and anti-extrusion ability a little less than; And the oilness of mineral oil and vegetables oil is very high, can form oil film in the metallic surface to reduce frictional resistance, so but because it can hinder show of oil and gas (SO﹠G) can not use when reservoir creeps into and in the prospect pit drilling well.
Therefore, press for the new lubricant of exploitation, this lubricant must have high lubricating property, is specially adapted to the use of horizontal well and orientation well, and has when subsurface environment changes and can not lose efficacy, and can not influence show of oil and gas (SO﹠G) simultaneously.
