Disclose a kind of additive that reduces the cement dehydration, it comprises quadripolymer, alkali, ionogen, at least a surfactant and water.Also disclose the method that a kind of production has the sand-cement slurry of improving dehydration performance, and a kind ofly be used for gasser and oil well carries out improving one's methods of cementation process.
Description
The present invention relates to cement mortar additive, this additive is to preventing that the sand-cement slurry dehydration from being effective.Another aspect of the present invention relates to the method that prevents the sand-cement slurry dehydration.A third aspect of the present invention relates to the sand-cement slurry with improvement dehydration performance.Another aspect of the present invention relates to carries out improving one's methods of cementation process to oil well and gasser.
In oil and natural gas industry, use cement-bonded composition, with the annular space in the wellhole between rock stratum around reinforcing and pipeline or the housing.Be typically, by annular space, sand-cement slurry is admitted to the housing inboard, and goes back up to hull outside.In order to form the water yield of sand-cement slurry, depend primarily on the type and the existing execution conditions of selected hydraulicity cement.Depend on factors such as slurry denseness and desirable strength.Water consumption can change in very wide scope.
In porousness or be bordering in the porous medium, must repeatedly water hydraulicity cement, for example, the stratum in the wellhole.When following situation took place, during the hardening of cement, water leached from mortar and infiltrates the rock stratum.Many difficulties are relevant with uncontrollable dehydration, the out of position of for example uncontrollable hardening rate, mortar, the weakening of strength property and the pollution of rock stratum on every side.Oil well and gasser are being carried out in the operation of cementation process, and these conditions not all are ideal.
In the past,, various materials have been used in order to reduce the dehydration of moisture sand-cement slurry.It's a pity that these materials usually have disadvantageous effect to cement itself.
For example, United States Patent (USP) the 4th, 015 No. 991, uses acrylamide and 2-acrylamide-2-methyl propane sulfonic acid to make the fluid loss additives of sand-cement slurry.Although this multipolymer can reduce the sand-cement slurry dehydration, but still there is the disadvantageous effect that reduces the cement compressive strength and delay hardening of cement speed.
Another problem of existing fluid loss additives is this additive in 300 and 450 temperature ranges, and is invalid.For example, United States Patent (USP) the 4th, 015, the multipolymer of narration in No. 991 is just invalid when temperature surpasses 250 °F.
