Description
Technical field
The present invention relates to a kind of solid foam water discharge agent composition and preparation method and applications, especially a kind of are directed to contain
Condensate well solid foam water discharge agent composition and preparation method and applications.
Background technique
With the reinforcement of gas-field exploitation dynamics, gas field is discharged the critical issue normally produced at gas well is restricted.Foam row
Hydromining gas is a kind of drainage gas recovery that recent domestic rapidly develops, simple, easy for construction, at low cost with equipment,
Applicable well depth range is big, does not influence the advantages that gas well normally produces.Foaming water discharge is exactly to pass through oil pipe or tubing and casing annular space to well
Interior injection foaming water discharge agent generates the foam with certain stability under the agitation of air-flow.The liquid phase that deposition is slipped in pipe becomes
For foam, change the relative density of lower curtate bit stream body in managing, quantity-produced gas phase displacement foam flows out pit shaft, so that well be discharged
Interior hydrops, achievees the purpose that water pumping gas production.
However, foam has " the quick property of oil ", after crude oil contacts foam, is sprawled or emulsified by film in gas-liquid and Ei,
It is entered in foaming structure under the action of external force and interfacial tension, so that foam contacting oils rear stability reduces.
The foam system for the most oil resistances reported at present is fluorocarbon surfactant, due to hydrogen atom in its hydrophobic chain
It is replaced by fluorine atoms, so that its hydrophobic chain, that is, hydrophobic and oleophobic, increases the oil resistivity of foam.However fluorocarbon surfactant produces
At high cost, expensive, poor biocompatibility, large-scale application may bring a series of environmental and safety problems, because
This still cannot replace hc-surfactant although its performance is brilliant.
The development of foreign countries' foaming water discharge agent since the eighties of last century sixties, multiselect sulfonate, benzene sulfonate, alkyl
The surfactants such as phenol polyethenoxy ether.Recompounded multielement system is mostly used greatly with foaming water discharge agent to current water pumping gas production, in order to
Enhance the stability of single foam, the auxiliary agents such as alkali, alcohol, polymer, alkanolamide are usually additionally added in formula and form strengthening foam.
US20120279715 reports the aerated fluid that gas recovery in a kind of gas well increases oil yield, is a kind of phosphinylidyne-containing amine group season
Ammonium surfactant has both bubble row and sterilizing function, and hydrophobic chain is the hydrophobic patch replaced in naphthalene nucleus, phenyl ring or natural grease,
Performance with very strong chlorine-resistant and condensate oil, under the conditions of nitrogen injection rate is 7/min, 20% condensation oil content, bubble
Foam discharge rate drops to 51.0% from 86.8%, and 50% condensation oil content drops to 29%.However due to containing in molecular structure
There is the amide group more sensitive to high temperature, thus it is poor to 100 DEG C or more of gas well adaptability.
China is the foam drainaging gas cutting process technology that begins one's study from the year eighties in last century, document " new and effective salt tolerant
The foaming properties of oil resistant solid foam water discharge agent KHD580A are studied and application ", it was recently reported that a kind of oil resistant foaming water discharge agent condensate
Content is 20%, displacement decline 23%.
The above foaming water discharge agent is mainly aqua, has the limitation of the several factors such as transport, storage, and liquid foam drains
Agent scene filling trouble.CN105062453 A discloses a kind of gas field solid foam water discharge agent and preparation method thereof, raw material group
