Abstract
The invention relates to a solid corrosion and scale inhibitor and a preparation method thereof. The scale inhibitor comprises the following components by weight percentage: 5 to 15% of phosphonate, 25 to 40% of phosphate, 20 to 30% of zinc chlorine, 5 to 10% of amine, 5 to 10% of disintegrating agent and 8 to 12 percent of citrate. The solid corrosion and scale inhibitor provided by the invention has excellent corrosion and scale inhibition effect, and drug efficiency is 30-40 days through on-site testing; after operations are carried out according to drug adding cycle, the oil casing, oil pipes, tension rods and other equipment in each oil well can be well protected, thereby meeting requirements on the operating performance of oil rigs during secondary or tertiary oil recovery; meanwhile, the drug adding cycle is prolonged, thus reducing perambulation cycle of the oil wells for maintenance personnel, reducing workload of maintenance personnel, and solving the problem of larger maintenance costs caused by frequent maintenance on oil rigs in current oil field.
Description
Technical field
The invention belongs to oil rig protection against corrosion, good antiscale property technical field, especially a kind of solid corrosion and scale inhibitor and preparation method thereof.
Background technology
Exploitation along with the oil field; Its reserves constantly descend; The normal countermeasure of using is that secondary or TOR are carried out in the oil field; But it is also increasingly high to use after this method in the oil well water ratio, the water ratio in oil well that has even up to 90%, and a large amount of mineral substance in the water make corrosion on Equipment scale formations such as oil well casing, oil pipe and pull bar very serious.Like oil recovery factory, Jilin Oil Field Qianan; There is more than 1,400 mouthful of oil well this oil recovery factory; The water ratio of oil well is 30～90%, and the salinity of water very high (saltiness reaches ppm up to ten thousand), also contains a large amount of sulfide in the water simultaneously; Water in the oil well has not only caused extremely strong corrosion to equipment like this, on equipment, forms fouling again.A lot of oil wells of this oil recovery factory are " month well workovers ", all need handle corrosion on Equipment, fouling in promptly every month, have not only seriously influenced the output in oil field, and maintenance has improved maintenance cost continually.In order to tackle the problems referred to above, this Oilfield using in oil well, add of the harm of liquid corrosion inhibiting and descaling agent with the burn into fouling that reduces water equipment is produced.During in the early stage test among a small circle, every mouthful of oil well needs to add a liquid preparation in per three days just can reach protection against corrosion preferably, fouling effect.But when large-scale promotion is used the method for in oil well, adding the liquid corrosion inhibiting and descaling agent, because the distance between every mouthful of oil well is different in more than 1,400 mouthful of oil well, the oil well of apart from each other even reach kilometers up to a hundred, the workload of whole interpolation process is very big.If rainy season, the vehicles can't arrive oil well basically, need maintenance personnel's walking just can finish the work, and have further strengthened the workload of adding work.In order to reduce workload, the cycle that the maintenance personnel adds the liquid corrosion inhibiting and descaling agent becomes every mouthful of oil well and adds once weekly, but through test; The concentration of the 4th day medicament behind the interpolation medicament has dropped to below the effective concentration; The effect that the medicament that was added in the five, six, seven days just has no.If the medicine machine that can robotization adds medicament is installed on every mouthful of oil well, not only disposable input is high, and the power consumption expense of daily maintenance cost and preventing freeze in winter is paid also height very.And when certain mouthful of oil well medicine machine breaks down, possibly can not carry out Automatic Dosing for a long time in this oil well.In sum, a kind ofly can slowly discharge and keep permanently effective corrosion inhibiting and descaling agent and can effectively reduce cost expenditure and reduce the work of maintenance personnel amount if can develop.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of solid corrosion and scale inhibitor of provide with low cost, anticorrosion-antiscaling effect good and it is effective for a long time to keep, reduce maintenance personnel's workload, reduction oilfield servicing cost being paid.
Solid corrosion and scale inhibitor provided by the invention is realized through following technical scheme:
A kind of solid corrosion and scale inhibitor comprises the following component of components by weight percentage:
Phosphonate 5～15%
Phosphoric acid salt 25～40%
Zinc chloride 20～30%
Amine 5～10%
Disintegrating agent 5～10%
Citrate trianion 8～12%.
And described phosphonate is HEDP sodium or ATMP sodium.
And described phosphoric acid salt is tsp or tripoly phosphate sodium STPP or Sodium hexametaphosphate 99.
And described amine is primary octadecylamine or tallow diamines.
And described disintegrating agent is a starch.
And described Citrate trianion is a Trisodium Citrate.
Another object of the present invention is to provide a kind of method for preparing above-mentioned solid corrosion and scale inhibitor: this method may further comprise the steps:
(1) by weight ratio with each component mixing;
(2) with each component oven dry, bake out temperature is 50～80 ℃;
(3) the material granulation at normal temperatures after the oven dry;
(4) material after granulation is accomplished carries out compressing tablet under normal temperature, 4～12 tons of pressure conditions, compressing tablet obtains the solid corrosion and scale inhibitor finished product after accomplishing.
Advantage of the present invention and beneficial effect are:
Solid corrosion and scale inhibitor provided by the invention has good anticorrosion-antiscaling effect, and through test in place, its drug effect is 30～40 days, promptly the dosing cycle of every mouthful of oil well be 30～40 days/inferior; After operating according to this dosing cycle, the equipment such as oil well casing, oil pipe and pull bar in every mouthful of oil well all can receive protection well, have satisfied the serviceability requirement of oil rig when secondary or TOR; The prolongation in dosing cycle has simultaneously also reduced the tour cycle of maintenance personnel to oil well, has reduced the work of maintenance personnel amount, has also avoided present oil field oil rig frequently to be keeped in repair and the problem of the big maintenance cost expenditure that produces.
