The weight percentages of the components are as follows: dodecyl aminoethyl phosphate ester: 8.5-12%; tetradecylaminoethyl phosphate: 7.5-9.0%; ethylenediaminetetraacetic acid disodium salt: 5-6.5%; ethylenediaminetetrapropionic acid tetrasodium salt: 2.5-3.0%; ethylenediamine tetramethylene phosphonic acid: 3.5 to 4.5; vitamin A: 0.05-0.08%, vitamin C: 0.05-0.12%, potassium iodide: 0.005-0.01%, alpha amino 3-methylbutyric acid: 0.0005 to 0.001%; aspartic acid: 0.0005 to 0.0010%; the balance of water; the sum of the weight percentages of the components is 100 percent. The effect is as follows: when the daily maintenance of an oil well is carried out, under the condition that the addition of the scale inhibitor for preventing the deposition of barium-strontium scales is 25-30 mg/l, the scale inhibition rate is more than 90%, and the pump inspection period of the oil well can be prolonged by more than 1 time.
Description
Technical field
The present invention relates to petroleum industry and use the chemical technical field, relate in particular to the Scale inhibitors that prevents oil well barium strontium dirt deposition in the oil recovery process.
Background technology
During getting into, the part oil field behind the high water-cut stage, contains barium, strontium, sulfate radical, carbanion, along with the variation of extraction liquid temp, at tube inner wall, sucker rod surface, the hard barium strontium dirt of the inner formation of gathering pipeline owing in the recovered water.And conventional barium strontium dirt prevents that method is ineffective, and this dirt is insoluble to acid simultaneously, has brought a lot of inconvenience for the oil field production management.
At present, the chemical scale inhibition agent roughly is divided three classes: i.e. aminopolycarboxylic acid's salt, phosphorus compound class and organic polymer class.Aminopolycarboxylic acid's salt is one a type low molecule sequestrant, like disodium EDTA (EDTA), CDTA salt (DCTA), ethylenediamine tetrapropionic acid(EDTP) salt (EDTP) etc.This type sequestrant is a low molecular compound, and the chelating stability constant is big, can be used for comparatively high temps, but because consumption is big, cost is high, and its application is restricted.
Mostly phosphorus compound class scale inhibitor is the organic multicomponent phosphonic acids.Like the ethylene diamine tetra methylene phosphonic acid (EDTMP) of methylenephosphonic acid type, with the HEDP (HEDP) of carbon diphosphine acid type, 4 of carboxy phosphonic acid type, 4-'-diphosphono-1,7-pimelic acid etc.Organic multicomponent phosphonic acid based scale inhibitor have consumption little, can bear comparatively high temps, lime carbonate is had higher advantages such as antiscale efficient, more in field use, relatively poor to the antiscaling effect of permanent white, Strontium Sulphate, scale inhibition performance has only about 40%.
The organic polymer scale inhibitor mainly is HPMA and ROHM and their multipolymer.The antiscale mechanism of this base polymer be on the polymer molecular chain carboxyl can with the polyvalent metal ion complexing, the complexing of a plurality of carboxyls then forms inner complex and has anti-scaling property.This base polymer is to the too late organic multicomponent phosphonic acids of the antiscale efficient of lime carbonate, calcium sulfate, though permanent white, Strontium Sulphate are had antiscaling effect, efficient is lower.
Summary of the invention
The objective of the invention is: a kind of Scale inhibitors that prevents barium strontium dirt deposition and preparation method thereof is provided.When the oil well routine maintenance, add Scale inhibitors, when the Scale inhibitors dosage that prevents barium strontium dirt deposition is under the situation of 25～30mg/l, scale inhibition performance is greater than 90%, and the pump detection period of oil well prolongs more than 1 times.
