Abstract
The invention discloses a high temperature-resistance salt-resistance oil well cement filtrate reducer. The raw materials used in the production of the reducer comprise AMPS(2-acrylamido-2-methyl propane sulfonic acid), acrylic acid, acrylamide, sodium hydroxide, potassium persulfate and water in a mass part ratio of 32-36:2.5-3:12-15:4-6:0.3-0.5:120. The high temperature-resistance oil well cement filtrate reducer prepared according to the formula is applicable to all-grade cement in accordance with API standards; the additive amount of the reducer in a slurry system at a high temperature of 210 DEG C is 5 to 8 percent of the total volume of slurry; and the water loss rate in well cementation can be effectively controlled within 50ml.
Description
One, technical field
The present invention relates to the used high temperature-resistance salt-resistance oil well cement filtrate reducer of a kind of reinforcing oil well.
Two, background technology
Used oil-well cement filtrate reducer incompatibility ultra deep well is cemented the well when well drilling and cementing at present, because of the ultra deep well temperature very high all between 180 °-250 °, usefulness all is the oil-well cement filtrate reducer that general well is used now, incompatibility high temperature and saturated saltwater mud system (ultra deep well must strengthen mud balance), oil-well cement filtrate reducer its viscosity under high-temperature condition reduces fluid loss and increases, and significantly reduces the well cementation effect.
Three, summary of the invention
The purpose of this invention is to provide a kind of high temperature-resistance oil well cement agent water retaining, solve the incompatibility ultra deep well high temperature of above-mentioned prior art existence and the problem of saturated saltwater mud system.
Raw materials for production of the present invention comprise AMPS (2-acrylamide-2-methyl propane sulfonic acid), vinylformic acid, acrylamide, sodium hydroxide, Potassium Persulphate and water, its ratio of quality and the number of copies is AMPS (a 2-acrylamide-2-methyl propane sulfonic acid): vinylformic acid: acrylamide: sodium hydroxide: Potassium Persulphate: water=32-36: 2.5-3: 12-15: 4-6: 0.3-0.5: 120
Its production method is in the water adding reactor of elder generation with 100 parts of mass fractions, add the AMPS that mass fraction is 32-36 part (2-acrylamide-2-methyl propane sulfonic acid) again, stir 5 parts of clocks, add the vinylformic acid that mass fraction is 2.5-3 part then successively, mass fraction is the acrylamide of 12-15 part, mass fraction is the sodium hydroxide of 4-6 part, be mass fraction that the Potassium Persulphate of 0.3-0.5 part is dissolved into 20 parts of solution in the water and adds in the reactors when being warmed up to 70 ℃, stop heating when solution is rapidly heated more than 85 ℃ in the question response still, open the reactor cooling, kept about 85 ℃ of temperature one hour, continue cooling, only fall and promptly produce high temperature-resistance salt-resistance oil well cement filtrate reducer behind the normal temperature.
The present invention is applicable to each class g cement of API standard, and dosage is the 5%-8% of total mud volume under the mud system of 210 ℃ of hot environments, and the fluid loss during well cementation can be controlled in the 50ml effectively; In 18% saturated brine system, this agent can with used admixture compatibility, fluid loss can suitably be adjusted according to the dosage of this product.

Five, embodiment
For further disclosing technical scheme of the present invention, elaborate below by embodiment: raw materials for production of the present invention comprise AMPS (2-acrylamide-2-methyl propane sulfonic acid), vinylformic acid, acrylamide, sodium hydroxide, Potassium Persulphate and water, its ratio of quality and the number of copies is AMPS (a 2-acrylamide-2-methyl propane sulfonic acid): vinylformic acid: acrylamide: sodium hydroxide: Potassium Persulphate: water=34: 3: 13: 5: 0.4: 120
Its production method is in the water adding reactor of elder generation with 100 parts of mass fractions, add mass fraction again and be 34 parts AMPS (2-acrylamide-2-methyl propane sulfonic acid), stir 5 parts of clocks, add mass fraction then successively and be 3 parts vinylformic acid, mass fraction is 13 parts a acrylamide, mass fraction is 5 parts a sodium hydroxide, be mass fraction that 0.4 part Potassium Persulphate is dissolved into 20 parts of solution in the water and adds in the reactors when being warmed up to 70 ℃, stop heating when solution is rapidly heated more than 85 ℃ in the question response still, open the reactor cooling, kept about 85 ℃ of temperature one hour, continue cooling, only fall and promptly produce high temperature-resistance salt-resistance oil well cement filtrate reducer behind the normal temperature.
Embodiment 2, victory section 1 well are the darkest up to now a bite wells of east China oil-field development, the well temperature reaches 210 ℃, because the existence of rock chlorion under the shaft bottom, therefore the content of salt in the grout has been done important requirement-saltiness during cementing design and must reach 18%. according to the technical parameter requirement, use water retaining of the present invention, be added in the amount of 5% cumulative volume in the mud system of 18% saturated brine, mud fluid loss in the time of 210 ℃ is controlled at the construction of 50ml. well cementation process smoothly, through the log data checking, cementing quality is good.
