Description
Technical field
The present invention relates to the oilfield chemical technology field, particularly a kind of whipping agent that is used for oil field foam profile control, the displacement of reservoir oil, drilling well and water pumping gas production.
Background technology
Since proposing with the thought of foam as mobility control agent first in 1958, domestic and international many research institutions have carried out 40 years of researches to foam technology.Foam is used widely in the displacement of reservoir oil, profile control, pressure break and drilling operation at present.Foam is a kind of dispersion system that gas forms in liquid phase under the whipping agent effect; The major cause that foam has profile control, displacement of reservoir oil effect is the seepage characteristic of foam in porous medium; Be foamy " stifled very much not stifled little, the not stifled oil of water blockoff " effect, cause foam in high and low pervious course, evenly to advance.Simultaneously, foam also has certain washing oil ability, thereby foam has the effect that significantly improves RF.
Foam also is widely used in drilling well and the water pumping gas production, and most of exploitation of oil-gas field is to the middle and later periods, and reservoir pressure descends.Adopting foam drilling is best choice, can improve drilling speed, reduce reservoir damage.And the gas recovery well gas production rate reduces, and problems such as water logging occur.The foaming water discharge gas production is simple owing to technology, less investment, instant effect, do not influence to produce and be widely used.
The key problem in technology that foam is used in oil-field development is the foaming properties of whipping agent, and the public patent major part of in the oil field, using about foam all is confined to single Application Areas at present, can not be applicable to a plurality of Application Areass simultaneously.As 98813947.2 a kind of prescription and method that is used for foam flooding is provided; 91103859.0 disclose a kind of foam system that is used for profile control; 200910016512.6 disclose a kind of pore forming material that is used for the heavy crude reservoir displacement of reservoir oil, 200810045167.4 disclose a kind of whipping agent preparation method of used for oil gas field drilling and extracting etc.This has limited the widespread use of foam in oil-field development to a certain extent.The invention provides a kind of whipping agent that is applicable to foam profile control, the displacement of reservoir oil, drilling well and water pumping gas production, its cost is low, free from environmental pollution, do not damage the stratum, is with a wide range of applications.
Summary of the invention
The object of the present invention is to provide a kind of whipping agent that is applicable to the foam profile control in the oil-field development, the displacement of reservoir oil, drilling well and water pumping gas production.It can adjust the composition and the proportioning of whipping agent according to the actual requirements, makes it be applicable to Application Areass different in the oil-field development.
Technical scheme of the present invention is: this is applicable to the whipping agent of oil-field development; Consist of by mass percentage: aniorfic surfactant content is 0.05～1.0wt%; Amphoteric ionic surfactant content is 0.05～1.0wt%, and non-ionics content is 0～1.0wt%, and suds-stabilizing agent content is 0.01～1.0wt%; Inorganic salt content is 0～0.8wt%, and surplus is a water.
Aniorfic surfactant in the whipping agent of the present invention can be one or more mixing as follows: alkyl-sulphate, alkyl alcohol polyoxyethylene ether sulfate, sulfonated alkylbenzene, sulfonated, sulfonated petro-leum, alkyl carboxylate; Amphoteric ionic surfactant can be one or more mixing as follows: alkyl betaine, sultaine, amino acid pattern; Non-ionics can be one or more mixing as follows: alkyl alcohol Soxylat A 25-7, alkylol amide, alkylol amide Soxylat A 25-7, alkyl polyglycoside, amine oxide type.Utilize the composite effect that can play synergy of anionic, amphoteric ion type and non-ionics, its foaming properties is better than single tensio-active agent, and compound system can reduce Financial cost simultaneously.
Suds-stabilizing agent in the whipping agent of the present invention can be one or more mixing as follows: SEPIGEL 305, Zulkovsky starch, modification guanidine glue, Mierocrystalline cellulose, high fatty alcohol, Triple Pressed Stearic Acid ammonium salt.In whipping agent, add suds-stabilizing agent and help increasing the foam solution film strength, improve foamy stability.Suds-stabilizing agent can also reduce tensio-active agent in use because the loss that reservoir rock absorption causes makes tensio-active agent better bring into play its foaming properties simultaneously.
For increasing the compatibleness and the flexibility of whipping agent and reservoir fluid; Can contain inorganic salt in the whipping agent of the present invention; Inorganic salt can be the inorganic salt that contain in the oilfield sewage, also can be one or more mixing as follows: sodium-chlor, sodium sulfate, sodium hydrogencarbonate, yellow soda ash, Repone K, calcium chloride, magnesium chloride.
The present invention has following beneficial effect: (1) this whipping agent can be adjusted the composition and the proportioning of whipping agent at any time according to the practical situation in different application field in the oil-field development, convenient production, wide adaptability.(2) this whipping agent production cost is low, and its whipability and foam stability are good, and the bubble of formation is even; Consumption is few, remarkable in economical benefits.(3) this whipping agent is free from environmental pollution, does not damage the stratum, has favorable biological degradability, does not contain prohibitive materials.
