Description
Technical field
The present invention relates to cement field, and in particular to a kind of HTHP stable type cement mortar.
Background technology
With going deep into for oil-gas exploration, deep-well, ultradeep well, geothermal well well cementation are increasing, at present manufacturer's application both at home and abroad
There is fracture, hydrolysis etc. in polymerization species fluid loss agent at most, the retarder strand under generally more than 130 DEG C of hot conditions
Situation, cause polymeric to form good absorption and parcel with oil-well cement again, cause cement and extra material
Grain causes to settle due to the effect of density contrast.
Fluid loss agent, the retarder class product of current all manufacturers be by AMPS and the polymerization of other functional monomers and
Into, and AMPS is the monomer for having sulfonic acid group, in the high temperature more than 120 DEG C and cement mortar alkaline environment (PH >=11) easily
Hydrolysis, the sulfonic acid (sodium salt) formed after hydrolysis have strong peptizaiton, further result in cement mortar sedimentation.
Meanwhile high density, VHD cement mortar, low-density, ultralow density cement slurries due to extra material, as heavy weight additive,
Palliative etc. and cement and other excessive (examples of extra material density contrast:Oil well G class g cements density is 3.15g/cm3Heavy weight additive density
4.80g/cm3-7.20g/cm3Palliative density 0.80g/cm3-0.24g/cm3), molecular thermalmotion aggravation is same in temperature-rise period
Sample causes cement mortar to settle.
The content of the invention
The technical problems to be solved by the invention are:The AMPS in retarder class product has sulfonic acid group in the prior art
Monomer, thus easily hydrolyzed in the high temperature more than 120 DEG C and cement mortar alkaline environment, the problem of causing to settle, it is therefore intended that
A kind of HTHP stable type cement mortar to solve the above problems is provided.
The present invention is achieved through the following technical solutions:
A kind of HTHP stable type cement mortar, including G levels oil-well cement, fluid loss agent, micro- silicon, high temperature retarder and
Water;Characterized in that,
The addition of micro- silicon is the 35-50% of G level oil-well cements, and the addition of fluid loss agent is G level oil-well cements
0.5-1%, the addition of high temperature retarder are the 2-5% of G level oil-well cements, and the addition of water is the 50- of G level oil-well cements
60%;
The high temperature retarder includes:
For the present invention by the optimization of formula, showing chemical inertness under the conditions of being effectively now below 50 DEG C in fact does not influence water
The live mixture and note of mud are replaced, and cause the increase of cement mortar viscosity under the hot conditions more than 90 DEG C, are effectively avoided often
Temperature thickening and the contradiction of high temperature sedimentation.
Meanwhile the present invention dissolves the rigid macromolecule group at high temperature, it can not only effectively improve cement mortar viscosity,
And end group bulky side chain therein can effectively prevent the hydrolysis of AMPS polymer, pass through the dual of the regulation of viscosity and anti-hydrolysis
Effect causes sedimentation to be obviously improved, and effect is very notable.
Further, the percentage by weight of monomer is 25%-35% in the high temperature retarder.
Further, the fluid loss agent is NVP.
Further, the addition of micro- silicon is 40-45%.
The present invention compared with prior art, has the following advantages and advantages:
1st, the present invention can effectively be now below showing chemical inertness in fact under the conditions of 50 DEG C and not influence the scene of cement mortar mixing
Match somebody with somebody and note and replace, and cause the increase of cement mortar viscosity under the hot conditions more than 90 DEG C, effectively avoid normal temperature thickening and high temperature
The contradiction of sedimentation.
2nd, the present invention dissolves the rigid macromolecule group at high temperature, and it can not only effectively improve cement mortar viscosity, and
And end group bulky side chain therein can effectively prevent the hydrolysis of AMPS polymer, pass through the dual work of regulation and the anti-hydrolysis of viscosity
With causing sedimentation to be obviously improved, effect is very notable.
3rd, cost of the present invention is cheap, and can effectively make retarder dosage and thickening time linear, Jin Ershi
Adjustable effect of existing thickening time.
