Abstract
The invention discloses an oil well cement retarder and a preparing method thereof. The oil well cement retarder is prepared from, by weight, 20 parts of 2-acrylamide-2-methylpropanesulfonic acid, 8-9 parts of maleic anhydride, 3.5-4.5 parts of fumaric acid, 1.5-2.5 parts of methacrylic acid, 60 parts of water and 1.5-2 parts of an initiator. The preparing method comprises the steps that firstly, all monomers and water are put into a container and prepared into a solution, and a sodium hydrogen carbonate solution with the concentration of 20% is used for regulating the PH value to be 6; then, the solution is transferred into a reactor, the reactor is put into a water bath pot to be heated, and meanwhile the solution is stirred; the temperature of the solution is maintained when increased to 60 DEG C, and nitrogen is introduced into the reactor for 30 min; finally, the initiator is added into the solution, the temperature continues to be maintained and stirring is carried out for 4 h, and the oil well cement retarder is obtained. The oil well cement retarder prepared with the method still can perform a good retarding effect when the temperature is high.
Description
Technical field
The present invention relates to oil well cement additive field, particularly relate to a kind of oil well cement retarder and preparation side thereof
Method.
Background technology
Retarder is can to prevent cement rapid condensation, prolongation cement slurry thickening time, to guarantee the one of construction safety
Class additive, when when burying the exploration and development carrying out oil gas field at oil well deep, that bottom hole temperature (BHT) temperature is high, well
The higher temperature in the end can cause the thickening time of oil-well cement to shorten, and common oil well cement retarder can not meet
Resistant to elevated temperatures use requirement.
Summary of the invention
Present invention seek to address that the deficiencies in the prior art, and provide a kind of high temperature resistant, effective oil-well cement to delay
Solidifying agent and preparation method thereof.
The present invention for achieving the above object, by the following technical solutions: a kind of oil well cement retarder, its feature
It is, is made up of the raw material of following parts by weight:
As preferably, described 2-acrylamido 2-methyl propane sulfonic acid can be replaced Sodium styrene sulfonate.
As preferably, described initiator is Ammonium persulfate..
The preparation method of a kind of oil well cement retarder that the present invention provides, it is characterised in that comprise the following steps:
(1) 2-acrylamido 2-methyl propane sulfonic acid, maleic anhydride, methacrylic acid and water are put into
In container, it is configured to solution；
(2) pH value using the sodium bicarbonate solution regulation solution of 20% is 6, transfers the solution into reaction
In device；
(3) reactor is placed in water-bath heating, solution is stirred simultaneously；
(4) it is incubated after solution is warming up to 60 DEG C, in reactor, is passed through the nitrogen of 30min；
(5) in solution, add initiator, continue to protect gentle agitation 4h, obtain oil well cement retarder.
The invention has the beneficial effects as follows: the oil well cement retarder that the present invention prepares can stop cement granules
Sedimentation, so that cement mortar has good stability, the macromolecular chain of the retarder being configured to has much sulphur
Acid groups and hydroxy-acid group, these polar group dispersibility are strong, and absorption is in the cation position of cement particle surface
Place, makes particle surface band like charges produce mutual repulsion effect, and the cohesion of suppression cement granules, especially at high temperature
Under this effect more intensive, hence in so that retarder remains to when temperature is higher play preferable retarding effect.
