Description
Technical field
The invention belongs to drilling operation technical field, particularly relate to a kind of Sialon ceramics mud slurry pump cylinder jacket and preparation method thereof.
Background technique
Along with socioeconomic develop rapidly, the mineral resources of shallow-layer are substantially verified, and reserves are very limited, are tending towards exhausted gradually.In order to solve problem of energy crisis, country proposes deep prospecting plan, the future development of probing industry forward deep-well, ultradeep well.Meanwhile, along with the fast development of Building Trade in China, industry also gets more and more with the geologic prospecting task of civil building, and drilling depth is also more and more darker.
In drilling process, utilize the drill bit pore-forming on rig, utilize slurry pump by the center hole on high pressure hose and drilling rod, by the mud force feed in surface mud pond to drill bit, to reach the object of cooling drill bit.Meanwhile, slurry pump also can gentlier be mixed with the slurry transportation of landwaste to earth's surface by cutting proportion, carries out hole operation clearly.
The working life of slurry pump, working efficiency depend primarily on cylinder sleeve performance.Cylinder sleeve is made up of external mold and liner, and material mostly is alloyed steel or cemented carbide.Mud slurry pump cylinder jacket, once damage, is changed the time and the manpower that get up to need at substantial, is affected the drilling efficiency of geologic prospecting, also can improve drilling cost.The medium of mud slurry pump cylinder jacket contact is the mud of certain sand content, weares and teares very fast.The cylinder sleeve external mold be made up of alloyed steel or cemented carbide and liner, the sand milling often and in mud is wiped, and abrasive resistance is limited, and the life-span is shorter.Therefore find a kind of highly abrasion-resistant new material make mud slurry pump cylinder jacket, extend operating life, for complete fast probing or geologic prospecting task provide safeguard, have broad application prospects in geological drilling field, significant.
The compound that Sialon ceramics is made up of silicon, aluminium, oxygen, several element of nitrogen, its hardness is high, wear resistance good, but toughness and collision resistance not good enough.If Sialon ceramics and alloyed steel are made compound body, using Sialon ceramics as liner, using alloyed steel as being molded as mud slurry pump cylinder jacket outward, the high wear resistance good characteristics of Sialon ceramics can be given full play to, the advantage such as the toughness that can play again alloyed steel is strong, collision resistance is good.
Through finding existing literature search, current engineering circles utilizes Sialon ceramics less as mud slurry pump cylinder jacket liner Study and appliance." improving the research in the drilling pump ceramic cylinder jacket working life " literary composition delivered in " modern technologies pottery " (the 3rd phase in 2010) as Gao Ruqin, complete for army building etc. is pointed out, engineering ceramics with the advantage such as its high hardness, high wear resistance, corrosion resistance, surface property be good, to be used widely in the cylinder sleeve of drilling pump being corrosive, containing high hardness solid phase particles.Although but the aluminium oxide ceramics hardness mentioned in literary composition and wear-resisting property higher, its fragility, shock resistance are difficult to meet usage requirement.In addition, although other pottery hardness be made up of silicon nitride, silicon carbide, wear resistance and resistance to compression, fracture resistance are better, oxidation reaction can be there is cause wearing and tearing under high temperature even normal temperature.
