Description
Technical field
The present invention relates to oil drilling field cementing extra-agent, especially a kind of anti-230 ℃ of oil well cements retardant and preparation method thereof.
Background technology
Retardant is an extremely important admixture in the hot hole cementing operation, is used for guaranteeing the pumpability of grout in the cementing operation process, guarantees that cement can reach the design level position smoothly.At present, also do not have and to have limited the work of exploration and development of China's ultra deep well at the oil well cement retarder of 230 ℃ of uses.
Summary of the invention
In order to solve the problem that exists in the background technology, the invention provides a kind of anti-230 ℃ of oil well cements retardant and preparation method thereof, this retardant can be suitable for 230 ℃ of superelevation hot-wells, reduce the deep well cementing cost, guarantee to exploit the benefit of deep layer hydrocarbon resources, the thickening time of control phreatic water mud, guarantee cementing operation safety.
The technical solution used in the present invention is: these anti-230 ℃ of oil well cement retarders are made by following raw materials according, each raw material by weight ratio: 170～180 parts of 2-acrylamidos-2-methyl propane sulfonic acid, 60～70 parts of aconitic acids; 1.0～1.5 parts of azo two isobutyl imidazoline salt hydrochlorates; 280～300 parts of deionized waters, 30%(W/W) NaOH is 260～270 parts.
The preparation method of described anti-230 ℃ of oil well cement retarders, this method comprises the following steps: to add 283.7 parts of deionized waters in stirring tank, add 172.4 parts of 2-acrylamido-2-novalgins, 67.6 parts of aconitic acids, open cooling water circulation stirring, slowly drip 266.3 parts of 30%NaOH, 15～30 ℃ of controlled temperature, with 5.0 parts of deionized water rinsing hoppers, add in the stirring tank, fed nitrogen one hour, be warming up to 60 degree, with 1.2 parts of azos of 5.0 parts of deionized water dissolvings, two isobutyl imidazoline salt hydrochlorates, drop in the reactor, keep 60 degree reactions promptly to get this retardant in 8 hours.
Utilization of the present invention contains the polymkeric substance of carboxyl, plays delayed coagulation by adsorption and sequestering action.Three aspect effects are roughly arranged: the one, because the absorption of multipolymer, make the normal hydrated state of cement particle surface be interfered (distortion), the generation of calcium hydroxide and nucleus were grown when inhibition or part had suppressed hydrated cementitious, and the aquation of cement is prolonged inductive phase, reached the slow setting purpose; The 2nd, because multipolymer adsorbs at cement particle surface, form diffusion double layer, make cement particle surface charged, suppressed intergranular coalescent, reach the purpose of slow setting; The 3rd, owing to contain more carboxyl in the copolymer molecule, have stronger metal-chelating ability, produce stable water-soluble ring texture by reaction and sequestering action, the parcel cement granules stops or delays the further aquation of cement, prolongation cement slurry thickening time.The preferentially adsorbed of multipolymer energy suppresses the formation and development of its nucleus in tricalcium aluminate, shows very strong delayed coagulation, tricalcium silicate and Dicalcium Phosphate (Feed Grade) is then shown more weak adsorptive power, thereby guaranteed the growth of cement later strength.In case intensity is arranged, its intensity is grown very fast, can satisfy the needs of later stage cementing operation, shortens construction cycle.
In the such scheme because the large percentage that accounts in polymkeric substance of AMPS play skeleton function, and this skeleton can not be degraded under high temperature, high pressure, shear conditions, good thermal stability, thus improved the temperature resistance ability of retardant integral body.What the retardant molecular weight was done in addition is generally bigger, general hundreds of thousands of all, at normal temperatures, molecular structure is in rolled state, and a large amount of slow setting groups are coated, and under action of high temperature, coiled structure will spread apart, the slow setting group is constantly discharged, thereby controlled the speed of hydrated cementitious under the high temperature, the downward modulation purpose of water saving livering time reaches a high temperature.
The present invention has this retardant of following beneficial effect: a. and can be suitable between 230 ℃ of superelevation hot-well b. thickening times and the retardant dosage relation and be linear substantially.C. the compatibleness that contains the water retaining of carboxylic monomer and this retardant is good.D. this retardant also has some improvement to the interface splicing to the ultimate compression strength effect of being significantly improved of cement stone, can consider this respect influence when formulating of recipe.
