The lubricant for drilling fluid comprises the following components calculating by weight percentage: a) 1 to 35 percent of long-chain organic acid oiliness agent; b) 1 to 35 percent of synthetic ester oiliness agent; c) 0.1 to 8 percent of emulsifier; and d) 25 to 90 percent of base oil; in which the synthetic ester oiliness agent is selected from at least one of isooctyl stearate, butyl isostearate, trimethylolpropane trioleate, trimethylolpropane palm kernel ester, trimethylolpropane ethylhexoate, neopentyl glycol oleate, methyl laurate or pentaerythritol caproate, therefore, the technical proposal solves the problem preferably, and can be used in the industrial production of lubricant for drilling fluid.
Description
Technical field
The present invention relates to a kind of lubricant for drilling fluid, relate in particular to and a kind ofly be used for deep-well, ultra deep well, long horizontal traverse well, horizontal well and from the required high density drilling fluid lubricant of formula well drilling process.
Background technology
Along with deepening continuously of domestic and international oilfield prospecting developing, deep-well, ultra deep well drilling hole number constantly increase.Deep-well, ultra deep well be deeply buried reservoir, the complex formation of bore meeting not only, and downhole temperature and pressure height, working cycle are long, and complexcase such as blowout, well slough, leakage take place easily.Drill smoothly and exploit in order to ensure safety, deep-well, ultra deep well drilling fluid generally adopt the mud of high-density high solid loading, and this kind high-density slurry can cause negative impact to the regulation and control and the maintenance of drilling fluid rheology, increase the rheological resistance of drilling fluid to a great extent, caused the rotational resistance of drill string and the resistance that makes a trip to increase substantially.
Because the lubricity that influence main may command factor that drill string moment of torsion and resistance in the drilling process and drilling tool wear and tear be drilling fluid, therefore the lubricity of drilling fluid is to down hole problems such as minimizing bit freezings, and assurance is crept into safely, fast and played crucial effects.The drilling fluid that lubricity is good can reduce moment of torsion, wearing and tearing and the fatigue of drilling tool, prolongs the work-ing life of bit bearing, prevents to adhere to bit freezing simultaneously, reduces ball-up, is easy to handle down-hole accident etc.
In drilling process, in order to improve the lubricity of drilling fluid, reduce moment of torsion and friction resistance, improve drilling speed, prolong the work-ing life of drilling tool, reduce the number of times that makes a trip, in drilling fluid base slurry, add a spot of lubricant usually, make drilling fluid form oil-in-water-type or water-in-oil-type mud, reduce oil water interfacial tension, and make surface of drill stem form one deck lubricant film, and well reduce the coefficient of friction resistance, strengthen the oilness of mud cake simultaneously by improvement of mud cake, thereby the speed that raising is crept into and the work-ing life of drilling tool, prevent the generation of accidents such as bit freezing, shorten drilling period, reduce drilling expense.
In shallow well, the middle-deep well drilling process, the general low-density drilling fluid of low solid content that adopts just can satisfy service requirements, add suitable regular mud lubricant at this drilling fluid base slurry, can obviously reduce rotary torque, the reduction friction resistance of drilling tool, thereby effectively prolong the work-ing life of drilling tool.But, in deep-well, ultra deep well drilling process, in order to prevent the generation of accidents such as blowout, need to adopt high density drilling fluid, even the common lubricant that adds excellent property also can't satisfy the lubricating requirement of bit bearing and drilling tool, cause the difficulty that makes a trip easily, even bit freezing and drillling tool twisting off accident take place to adhere to.In order to prevent the generation of this type of situation, the lubricant that must add the high density drilling fluid special use improves the oilness of drilling fluid, and to reduce the friction between the borehole wall and the drilling tool, what guarantee that ultra deep well creeps into carries out smoothly.
About lubricant for drilling fluid, both at home and abroad periodical and patent have many reports, but are applicable to that the required lubricant of deep-well, ultra deep well drilling process middle-high density drilling fluid is without any disclosed technical literature and patent.
The disclosed a kind of novel lubricant for drilling fluid of patent CN1367222A " lubricant for drilling fluid " has characteristics such as good water solubility, stability is strong, temperature resistance is good, usage quantity is low.In density is 1.23 gram per centimeters
3Drilling fluid base slurry in add 4% this lubricant, frictional coefficient drops to 0.0875 by 0.2773.CN101157850 " preparation of high temperature resistant lubricant for drilling liquid by animal plant oil " discloses and has utilized preparation of high temperature resistant lubricant for drilling liquid by animal plant oil.This lubricant is the highly-efficient lubricant in deep drilling, prospect pit and the various complicated well construction process.Patent CN1743404 " a kind of drilling fluid lubricating additive and preparation method thereof " discloses a kind of good lubrication drag reduction effect that has, and resists salt, the very capable lubricant for drilling fluid of calcium ion erosive.In density is 1.05 gram per centimeters
3Drilling fluid base slurry in add 1% this lubricant, the frictional coefficient of drilling fluid is by dropping to about 0.1 more than 0.5.US5826669 " Drilling Fluid Loss Prevention and LubricationAdditive " is by adding competent whippy graphite granule in drilling fluid, design a kind of the prevention or the lubricant of control wellbore liquid leaching loss in micropore or the breaking up rock, effectively reduce make a trip in the drilling process resistance and rotary torque, reduce the casing wear in the drilling process.US5837655 " Purified paraffins as lubricants; rate of penetrationenhancers; and spotting fluid additives for water-based drilling fluids " discloses a kind of nontoxic, high purity paraffin that can biological explanation, as the lubricant and the permeate agent of water-base drilling fluid.Above-mentioned patent documentation is not all mentioned the applicable cases in high density drilling fluid.
Summary of the invention
Technical problem to be solved by this invention is the problem of lubricant for drilling fluid of the prior art lubricity difference in high density drilling fluid, and a kind of new lubricant for drilling fluid is provided.This lubricant for drilling fluid is used for water-base drilling fluid; at deep-well, ultra deep well, horizontal well, long horizontal traverse well, orientation well with from formula well drilling process; can increase substantially the lubricity of high density drilling fluid; on the metal surface of drill stem and the borehole wall, form the firm adsorption film of one deck; effectively reduce moment of torsion and friction resistance in the drilling process; reach the protection surface of drill stem, prolong the drilling tool purpose in work-ing life.
