Description

Novel foaming agent in fracture acidizing liquid
Technical field
The invention belongs to the technical field of oilfield chemistry product, be specifically related to the novel foaming in a kind of fracture acidizing liquid Agent.
Background technology
In acidification of oil field fracturing reform, in order to obtain the ideal effect of fracture acidizing volume increase, typically require that active acid is made Big by scope, stretch out as far as possible.Owing to foamed acid has slowly, liquid content is few, low leak-off, not the feature such as polluted reservoir, Therefore, apply in the oil formation improvement of oil field quite varied.
In foam acid solution, crucial foaming agent (foaming agent), there is its acid solution could be referred to as foamed acid.To its requirement it is Foamability is strong, and long half time, emulsifying degree is little, good with various additive compatibilities.Preferably foaming agent (foaming agent) is necessary Possess following performance:
1. can be effectively reduced the surface tension of acid solution and the interfacial tension of oleic acid, the low interfacial tension of acid solution, make acid solution Being easily accessible in the hole on stratum, expand the process range of acid solution, the most beneficially spent acid returns row.
2. foaming abundancy, long half time, repeats frothing capacity good.
3. there is good demulsification performance. containing natural activity in crude oil, oleic acid is easily formed high viscous emulsion and results in blockage, Activating agent in acid solution must be able to be effectively prevented acid solution emulsifying.
4. suspendability is good. and will produce some solid particles not being dissolved during acidifying, acid solution has good suspending power, makes These granules discharge ground with waste liquid, are unlikely to cause secondary injury.
5. water-wet is good. and added foaming agent must assure that the wettability on stratum, to improve oleic permeability, increases former Oil yield.
6. Heat stability is good. after foaming agent enters stratum, heat to keep its activity, is the most just conducive to acid discharge.
7. adsorptivity ability is low. and foaming agent to be difficult to be adsorbed by stratum, remains certain activity, and this is the most residual The row of returning of acid.
At present, market also has some foaming agents, but certain limitation should be used, and mostly be one-component and produce Product.Therefore, select foaming agent to select according to molecular structure, but single molecular structure is difficult to meet acidifying foaming agent, anxious Need to there is a kind of foaming agent meeting multiple performance.
Summary of the invention
It is an object of the invention to provide the novel foaming agent in a kind of fracture acidizing liquid, mainly solve acidification of oil field pressure Split the construction problem of well (less than 140 DEG C) in transformation.
The technical scheme is that
Novel foaming agent in fracture acidizing liquid, its each component is following component by weight percentage:
Myristyl sodium sulfonate and sodium cetanesulfonate: 45-56%,
OPEO and NPE: 32-43%,
Stain removal agent: 8-18%,
Bath gel: 3-15%,
Water: surplus.
Described stain removal agent is commercially available Amway product, and described bath gel is also commercially available Amway product.
As preferably, the novel foaming agent in the fracture acidizing liquid of the present invention, its each component is by weight percentage Following component:
Myristyl sodium sulfonate and sodium cetanesulfonate: 45-52%
OPEO and NPE: 35-40%
Stain removal agent: 8-12%
Bath gel: 6-12%,
Water: surplus.
Further preferably, the novel foaming agent in the fracture acidizing liquid of the present invention, its each component is by weight percentage The following component of meter:
Myristyl sodium sulfonate and sodium cetanesulfonate: 46%
OPEO and NPE: 36%
Stain removal agent: 8%
Bath gel: 6%,
Water: surplus.
Wherein, consumption (weight) proportionate relationship of myristyl sodium sulfonate and sodium cetanesulfonate is, myristyl sulphur Acid sodium: sodium cetanesulfonate=1-3:1-2.
As preferably, consumption (weight) proportionate relationship of myristyl sodium sulfonate and sodium cetanesulfonate is, the tetradecane Base sodium sulfonate: sodium cetanesulfonate=1:1.
Wherein, consumption (weight) proportionate relationship of OPEO and NPE is, octyl phenol Polyoxyethylene ether: NPE=1-3:1-2.
As preferably, consumption (weight) proportionate relationship of OPEO and NPE is, pungent Base phenol polyethenoxy ether: NPE=1:1.
Further preferably, the novel foaming agent in the fracture acidizing liquid of the present invention, its each component is by weight percentage The following component of meter:
Myristyl sodium sulfonate: 23%
Sodium cetanesulfonate: 23%
OPEO: 18%
NPE: 18%
Stain removal agent: 8%
Bath gel: 6%,
Water: surplus.
Novel foaming agent in the fracture acidizing liquid of the present invention, in proportion, operation the most at normal temperatures and pressures is joined System, does not has three-waste pollution, carries out mixing the most available by said components by conventional compound method.
The invention have the benefit that
The poly-foam that becomes in vitro of the bubble kept apart by fluid film or solid film, the bubble that only liquids and gases are formed Foam becomes liquid foam.Consequently only that solution just can have obvious bubble, in general, aqueous surfactant solution can bubble, This is mainly caused by its molecular structure own.
Anion surfactant foaming agent, foaming power and lipophilic group carbon number, the structure etc. of lipophilic group relevant, former When subnumber is 12-16, foaming power is the strongest, and when carbon atom reaches 18, foaming power declines suddenly；If lipophilic group has side chain, foaming characteristic Can be deteriorated；When hydrophilic group molecule is positioned at molecule central authorities, foaming characteristic significantly reduces.
The present invention is with myristyl sodium sulfonate, and sodium cetanesulfonate is main, and its foamability is very strong, foam height, Density and half-life are the most very good, are equipped with OPEO, NPE makes bubble become uniform, fall Low broken bubble rate.It is equipped with stain removal agent (Amway product) simultaneously and bath gel (Amway product) makes the surface tension of foaming agent, interface Tension force is lower, is so more beneficial for washing oil, is more conducive to reduce and adsorbs on stratum, the most just improves foaming agent rising in residual liquid Bubble property, the beneficially row of returning of residual liquid.
In a word, product of the present invention is the joint product of various ingredients, and it is effective, is mainly used in acidification of oil field fracturing reform In the construction of well (less than 140 DEG C).
