Abstract
Special solid phase free flushing liquid is used for loose and broken formation with drill sampling.The present invention relates to solid phase free flushing liquid and be used for loose and broken formation with drill sampling.This washing fluid is formulated respectively by two kind of plant glue.A kind of is formulated by nettle powder, soda ash or caustic soda and water; Another kind is formulated by Rhizoma amorphophalli powder, caustic soda, borax, water and acid.These two kinds of washing fluids match with diamond drilling respectively, improve core-taking rate in loose and broken formation, with drilling through out approximate original state rock sample, improve and creep into rotating speed in soft layers such as thin sand, folder mud layer, reduce the diamond head wearing and tearing, prolong its life-span.
Description
The present invention relates to solid phase free flushing liquid and be used for loose and broken formation with drill sampling.
The clay-free drilling fluid of (middle translation is seen " mineral exploration engineering collected translation " the 4th phase in 1985) low solids fluid treatment agent EZ-MUD preparation of NL Bayoid of Canada Ltd " DRILLING FLUID " (nineteen eighty-three) record is applicable to that the diamond core drill advances.Creep in regular mud and stablely easily to expand, to collapse or collapse diffusing water-sensitive strata, eliminate the drilling rod vibrations of diamond core drill in advancing.But, use not clear and definite for the drive sampling in loose and broken formation.
The objective of the invention is to utilize special solid phase free flushing liquid SM or MY to match, improve core-taking rate, in thin sand, folder mud layer,, reduce the diamond head wearing and tearing, prolong its life-span with drilling through out approximate original state rock sample at loose and broken formation with diamond drilling.
Solid phase free flushing liquid of the present invention can be formulated respectively by two kind of plant glue.A kind of is the solid phase free flushing liquid of SM vegetable jelly preparation, and it is by nettle powder (SM), soda ash (Na
2Co
3) or caustic soda (NaOH) and water cooperate and form.Use soda ash when temperature is high, normal temperature or normal temperature are following effective with caustic soda.The mixing ratio by weight of its composition is: the nettle powder: water=(1～3): 100, nettle powder: soda ash (solid)=100: (3～8), or nettle powder: caustic soda (solid)=100: (2～5), the optimum weight proportioning of its composition is: the nettle powder: water=2: 100, nettle powder: soda ash (solid)=100: 5 or nettle powder: caustic soda (solid)=100: 3.During preparation, soda ash or caustic soda are added in the entry dissolve earlier, then the nettle powder evenly is sprinkled in the buck, spread while stirring, prevent conglomeration, available stirrer or artificial hand stir, and stir after 20-30 minute, leave standstill immersion for some time, can use.Soak time is decided according to temperature and viscosity, and funnel viscosity reaches more than 1 minute and can use, and temperature is low more, and then soak time requires long more.Another kind is the solid phase free flushing liquid of MY vegetable jelly preparation, it is by Rhizoma amorphophalli powder (MY), caustic soda (NaOH), borax, water and acid (for example hydrochloric acid) are formulated, the mixing ratio by weight of its composition is: Rhizoma amorphophalli powder: water=(0.4～0.6): 100, Rhizoma amorphophalli powder: caustic soda (solid)=100: (30～50), Rhizoma amorphophalli powder: borax (solid)=100: (40～60), the dosage of acid (for example hydrochloric acid) is so that the pH value of slurries reaches between the 7-9 is as the criterion, the optimum weight proportioning of its composition is: Rhizoma amorphophalli powder: water=0.5: 100, Rhizoma amorphophalli powder: caustic soda (solid)=100: 40, Rhizoma amorphophalli powder: borax (solid)=100: 50, the dosage of acid (for example hydrochloric acid) is so that the pH value of slurries reaches between the 7-9 is as the criterion.When preparation, available machines used stirs, the most handy post-type mixer, in stirrer, add earlier clear water, amount of water is 1/3 or 1/4 of whole amount of water, once adds whole caustic soda and is stirred to dissolving, is sprinkled into Rhizoma amorphophalli powder then in stirrer, spread while stirring, treat that Rhizoma amorphophalli powder all is dissolved into transparent glue (no white particle), add whole water yields and continue to stir, require funnel viscosity to reach more than 22 seconds, regulate with acid (for example hydrochloric acid) between pH value to 7～9 of slurries, borax solution is once added, and stir 1～2 minute promptly crosslinked, but blowing uses, at this moment, funnel viscosity is the drip state.(the MY solid phase free flushing liquid is to be used in the MY-IA solid phase free flushing liquid of basement rock in creeping into according to Zhongnan Polytechnic Univ get through changing prescription, is applicable to that the loose and broken formation diamond drilling takes a sample, and also is applicable to diamond drilling in the basement rock.）
Nettle powder and Rhizoma amorphophalli powder that the present invention is used are the flours of being made with conventional grinding and processing method by the konjaku of wild bush Root of Narrowleaf Nettle and artificial growth.
Under normal temperature or hot weather, preparation is during washing fluid, and it is anticorrosion to add sanitas (for example formaldehyde) in slurries.
With SM or the drive sampling of MY solid phase free flushing liquid gold conjugate hard rock, its drive sampling working method and conventional clear water drilling operation method are basic identical.
The present invention adopts SM or MY solid phase free flushing liquid, because these two kinds of washing fluids have hydrophobicity when high viscosity, core had protective colloid effect preferably, the boring of diamond drilling, not only the core recovery in full hole increases substantially, particularly in sand gravel stratum, reach more than 70% at loose and broken formation, and can be with drilling through out approximate original state rock sample in soft layers such as thin sand, folder mud layer, the true grain composition and the structure that have reflected the stratum help engineering geology is made correct evaluation.In addition, because SM or MY solid phase free flushing liquid have lubricated, elastic shock attenuation effect, improved rotating speed and bit life, in loose and broken formation, the circumferential speed of diamond drilling reaches 2.5～5.9 meter per seconds, and the diamond head life-span reaches 20～40 meters/.
