Abstract
The invention relates to a foaming agent for well drilling under a high temperature environment. The foaming agent is prepared by the steps: placing 35-70 parts of higher fatty alcohol, 20-50 parts of aminobenzenesulfonic acid and 250-450 parts of water in a high-temperature high-pressure stainless steel reaction kettle with a stirring device, closing a lid, heating to 110-150 DEG C under continuous stirring, holding for 1-2 h, then stopping heating, and slowly dropwise adding 13-38 parts of stearic acid; when the temperature is less than 90 DEG C, adding 12-60 parts of N,N-dimethyl dodecane amine, carrying out a reaction for 2.5-4 h under the condition of the temperature of 65-90 DEG C, stopping heating, and cooling to the room temperature; and then adjusting the pH value to 5-7 with 5-18 parts of ethylenediamine tetraacetic acid while stirring, and thus obtaining the foaming agent which has the color from light yellow to yellow and is used for well drilling under the high temperature environment. The foaming agent can still maintain good foam property in deep wells or high-temperature geothermal wells, and has good effects of improving the well drilling speed, carrying drilling cuttings, preventing leakage and stopping leakage.
Description
Technical field
The present invention relates to oil-gas field development field, particularly drilling technique field, is under a kind of applicable high temperature (350 ℃) environment, to improve the whipping agent that drilling speed foam drilling is used.
Background technology
Foam drilling is the important component part of gas drilling, is one of important way effectively improving competent formation rate of penetration, and particularly along with expanding economy, exploitation and the Looking For Substitutions Of Oil of deep-well are more and more urgent.Foam drilling is as improving the most effective means of rate of penetration, and high temperature resistance whipping agent is the core technology that forms high temperature foam fluid.For example high-temperature geothermal drilling well, because high-temperature geothermal is generally contained in Stratum of Volcanic Rocks, fracture development, and well temperature is high, and underground temperature gradient is more than 7 ℃ conventionally,
More than 2000 meter, some wells, bottom temperature can reach 350 ℃ of left and right.The aerated fluid that this requirement forms has and under hot environment, has good foaming properties and shutoff.
Summary of the invention
The object of this invention is to provide drilling well whipping agent under a kind of high temperature (350 ℃) environment, be applied to improve the drilling speed of deep-well under hot environment or geothermal drilling and keep well cleaning action.For fuel oil meter oil/gas deep well, ultra deep well, foam drilling has protection reservoir, reduces the effect of pressure differential sticking; For geothermal drilling, foam drilling has leak-proof leak-stopping effect.
Under a kind of hot environment of the present invention, drilling well is with whipping agent by weight by high fatty alcohol, aniline sulfonic acid, stearic acid, N, and N-dimethyl n-Laurylamine, ethylenediamine tetraacetic acid (EDTA) and water form.
Wherein: high fatty alcohol is the fatty alcohol of lauryl alcohol, palmityl alcohol or C12～C18.
Aniline sulfonic acid is ORTHO AMINO PHENOL SULPHONIC, m-sulfanilic acid or Sulphanilic Acid.
30～90 parts of high fatty alcohols;
15～60 parts of aniline sulfonic acids;
10～45 parts of stearic acid;

3～20 parts of ethylenediamine tetraacetic acid (EDTA)s;
200～500 parts, water.
Each component all belongs to Industrial products, and there is sale in market.
The reasonable drilling well whipping agent of foaming properties under hot environment, the weight part of each component is:
35～70 parts of high fatty alcohols;
20～50 parts of aniline sulfonic acids;
13～38 parts of stearic acid;
N, 12～60 parts of N-dimethyl n-Laurylamines;
5～18 parts of ethylenediamine tetraacetic acid (EDTA)s;
250～450 parts, water.
The preparation of whipping agent for drilling well under a kind of hot environment of the present invention:
Major equipment:
There is stainless steel cauldron under the High Temperature High Pressure of stirring, heating, cooling system.
The preparation method of whipping agent for drilling well under a kind of hot environment:
By 35～70 parts of high fatty alcohols, 20～50 parts of aniline sulfonic acids and 250～450 parts of water are placed in the High Temperature High Pressure stainless steel cauldron with whipping appts, cover lid, under constantly stirring, be heated to 110～150 ℃, keep stopping heating after 1～2h, slowly drip 13～38 parts and add stearic acid, temperature is during lower than 90 ℃, add 12～60 parts of N, N-dimethyl n-Laurylamine reacts 2.5～4h under 65～90 ℃ of conditions, stop heating, cool to room temperature, then be adjusted to while stirring pH value between 5～7 with 5～18 parts of ethylenediamine tetraacetic acid (EDTA)s.Obtain drilling well whipping agent under faint yellow extremely yellow hot environment.
The use of whipping agent for drilling well under a kind of hot environment of the present invention:
0.5% whipping agent is joined in fresh water or seawater, will be not through and through 300 ℃ of heat roll 16h containing foaming agent solution, the result that the high speed agitator by 11000rpm stirs 1min test foaming properties (foam volume and transformation period) is in limit of error.
For this whipping agent, fresh water, seawater all have good foam performance, roll after 16h in the roller heating stove of 300 ℃ with fresh water or seawater, it is basically identical that heat is rolled front and back foaming properties, press under the vapour-liquid ratio condition of 1:1 or 1:2 at pressurized air or nitrogen with fresh water or seawater, the aerated fluid forming by porous medium has compare with conventional whipping agent high pressure reduction, i.e. shut-off capacity.
Under a kind of hot environment of the present invention, drilling well whipping agent is a kind ofly can still have and good foaming properties in hot environment, can remain in deep-well or high-temperature geothermal well and still can keep good foaming properties, there is good raising drilling speed, carry drilling cuttings, leak-proof leak-stopping effect.
