Abstract
On the basis of analysis of a composition and physicochemical conditions of an accumulated fluid of a natural gas well, based on a synergistic effect between an anionic surfactant and a nonionic surfactant, through compounding of the anionic surfactant and the nonionic surfactant, and with supplement of modification of a foam stabilizer and an amphoteric surfactant, a foam drainage agent which is strong in fluid-carrying capability and can meet drainage and gas exploitation of the natural gas well containing more gas condensate and having relatively high alkaline earth metal ion concentration in the well cylinder accumulated fluid is obtained. The foam drainage agent is applicable for drainage and gas exploitation of the natural gas well, and especially for drainage and gas exploitation of the natural gas well having high gas condensate content and high alkaline earth metal ion concentration.
Description
Technical field
The present invention relates to the chemical assistant of the water pumping gas production of the gasser in oil-gas field development field, particularly a kind of, salinity high at stratum condensate oil content greatly and wherein calcium ions and magnesium ions content high, have a large amount of methyl alcohol to deposit the foaming water discharge agent of water pumping gas production in case.
Background technology
Foaming water discharge agent (hereinafter referred to as foam discharging agent) for gasser be a class based on tensio-active agent, and be aided with other chemical assistants composite, for the chemical assistant of gasser water pumping gas production.The principle of foam discharging agent water pumping gas production is the foam performance that make use of tensio-active agent, and by the stirring action of gas well natural gas, the hydrops of gas well (comprising the chemical substance of water, condensate oil, methyl alcohol that suppression gas hydrate are formed and add and other naturally occurring or artificial filling on stratum) foam and forms continuous rising, more stable foamy column, hydrops and some solid particulates in well are carried out in gasser, reduce the hydrops height of gasser, reduce the back pressure of Sweet natural gas extraction, thus realize the lifting of Sweet natural gas.The object realized as required and the formula formed, foam discharging agent can realize bubbling, taking liquid, dispersion, drag reduction, washing simultaneously, even the several functions such as sediment outflow, scale inhibition, inhibition.The most basic function of foam discharging agent is water pumping gas production, and this requires that foam discharging agent can have higher fluid-carrying capability under stratum (down-hole) physical and chemical condition, and this requires that foam discharging agent need meet following requirement.
(1) foam discharging agent need meet the requirement of formation temperature.From hundreds of rice to thousands of rice not etc., due to the existence of formation temperature gradient, this just requires that foam discharging agent has good foaming, steady bubble and foam carrier ability under the condition of formation temperature for the degree of depth of gasser.For general tensio-active agent, have good froth stability at 40-60 DEG C, temperature rising can cause the viscosity degradation of liquid and foam, thus froth stability declines.Therefore, composite foam discharging agent should be able to meet the requirement of down-hole use temperature.
(2) foam discharging agent need meet the requirement used under gas well salinity condition.Salinity rises and means the increase of solution ion strength, and impact served by the use band of this meeting Surfactant.Special when solution contains more alkaline-earth metal ions (as calcium ions and magnesium ions), these alkaline-earth metal ions can and anion surfactant (as sodium lauryl sulphate, sodium laurylsulfonate, Sodium dodecylbenzene sulfonate, sodium oleate) can precipitation be generated, thus the foaming that reduction even worsens foam discharging agent is surely steeped, foam carrier ability.So for the gasser containing more alkaline-earth metal ions in pit shaft hydrops, foam discharging agent used should have the ability of good anti-salinity and alkaline-earth metal ions.
(3) foam discharging agent need meet the ability of condensate oil.The condensate oil of gasser is outwardness, and the content of the condensate oil of different gasser may be different.But condensate oil is a kind of defoamer, its existence can reduce that the foaming of foam discharging agent is surely steeped, foam carrier ability.So foam discharging agent should have good condensate oil ability.
(4) foam stable ability of foam discharging agent.Foam discharging agent only has good froth stability (surely steeping ability), pit shaft hydrops could be carried into ground by foamy column.On the other hand, arrive the foam on ground when foam killer filling or the condition of change, foam will easily be vanished.Only in this way, production could continue to carry out and reclaim the condensate oil carried secretly in foam.So the stability of foam will be got well, but can not be too strong.
Domestic foam discharging agent uses as far back as Gas field, and in the whole nation, each Gas Fields is promoted at present.Chinese patent CN 101492599A discloses a kind of foaming water discharge agent and preparation method thereof.This invention obtains a kind of foaming water discharge agent with foaming water discharge, inhibition and anti-scaling function by triethylene tetramine, oleic acid, glacial acetic acid, maleic anhydride, vinylformic acid, citric acid, tetrahydroglyoxaline etc. composite.Chinese patent CN 102212348A discloses a kind of anti-salt, methanol tolerance foam discharging agent.It is composite that this foam discharging agent employs coconut oleoyl amine third class trimethyl-glycine, amine oxide, alpha-alkenyl sulphonate, trolamine, fluorocarbon surfactant etc.The foam discharging agent prepared solves the water pumping gas production problem in high salinity and note methyl alcohol gas well.
Summary of the invention
The present invention is on the basis of the composition and physical and chemical condition of analyzing gasser hydrops, based on the synergistic effect between dissimilar tensio-active agent, develop a kind of fluid-carrying capability strong, can meet under severe condition, particularly in pit shaft hydrops containing more condensate oil and the foam discharging agent of water pumping gas production of gasser with higher alkaline-earth metal ions concentration.
Technical scheme of the present invention is as follows:
Foaming water discharge agent of a kind of condensate oil and salinity and preparation method thereof, key step is: get a certain amount of suds-stabilizing agent and water respectively, be heated to 30-50 DEG C, stir, dissolve, add the water of the anion surfactant of specified amount, zwitterionics, nonionogenic tenside and remainder more successively, continue constant temperature to stir, dissolve to obtain the homogeneous solution of reddish-brown.
