Description
Technical field
The present invention relates to a kind of technical field of multifunctional drilling fluid additive, particularly relate to a kind of multifunctional drilling fluid additive used for petroleum drilling.
Background technology
Petroleum drilling fluid auxiliary agent is used for oil drilling wax removal, inhibition, anti-swollen, de-plugging etc.At present, the mud conditioner used in petroleum drilling has tens of kinds, use, the treatment agent of difference in functionality must be added according to the difference of the aqueous condition of well, when ratio collocation is bad, does not reach required effect, even have the opposite effect, easily cause slump in, tight trip, chance card, the more serious full well that causes is scrapped, waste of manpower and goods and materials.
Summary of the invention
The object of the invention is the shortcoming in order to overcome above-mentioned prior art, there is provided a kind of multifunctional drilling fluid additive, this multifunctional drilling fluid additive can complete and drilling fluid is played to anticalcium, anti-salt, filtrate reducing, anti-collapse, lubrication, regulates rheological and improve sand ability etc.
The technical solution adopted for the present invention to solve the technical problems is: a kind of multifunctional drilling fluid additive, is made up of the composition of raw materials component of following mass percent: 50-100 part diacetone-acryloamide(DAA), 50-100 part Methacrylamide, 10-15 part ammonium persulphate, 20-30 part ethylene glycol, 50-80 part tosic acid, 100-120 part trifluoromethanesulfonic acid, 1-3 part copper hydroxide, 1-3 part ammonium nitrate, 2-3 part ammonium persulfate, 3-5 part Textone.
Further, described diacetone-acryloamide(DAA) is 50 parts, Methacrylamide is 50 parts, ammonium persulphate is 10 parts, ethylene glycol is 20 parts, tosic acid is 50 parts, trifluoromethanesulfonic acid is 100 parts, copper hydroxide is 1 part, ammonium nitrate is 1 part, ammonium persulfate is 2 parts, Textone is 3 parts.
Or described diacetone-acryloamide(DAA) is 100 parts, Methacrylamide is 100 parts, ammonium persulphate is 15 parts, ethylene glycol is 30 parts, tosic acid is 80 parts, trifluoromethanesulfonic acid is 120 parts, copper hydroxide is 3 parts, ammonium nitrate is 3 parts, ammonium persulfate is 3 parts, Textone is 5 parts.
In sum, the invention has the beneficial effects as follows: multifunctional drilling fluid additive tool of the present invention has the following advantages:
1. there is good filtrate loss controllability;
2. substantially do not carry sticky in drilling fluid;
3. anti-salt, anti-magnesium and anticalcium, can be applicable to fresh water, salt solution and seawater drill in fluid;
4. good thermostability, temperature resistance reaches 140 DEG C;
5. good with treatment agent compatibleness;
6. nontoxic, be conducive to environmental protection.
