Description
Technical field
The present invention relates to chemistry and fill nitrogen Cementing Technology of Foamed Cement, particularly relate to a kind of novel chemical nitrogen-charge foam cement slurry system and composition thereof.Specifically, the present invention directly produces nitrogen by chemical method thus the stable foamed low density grout of processability in grout.
Background technology
Foam slurry is by insufflation gas in grout, froth stability is improved with tensio-active agent or polymer substance etc., thus prepare stable, uniform low density three-phase viscous fluid, there is density low, low permeability, low dehydration, low heat conductivity, compressibility, unique rheological property, suitable thixotropy and intensity high, effectively can solve low pressure and leakmess formation, fracture formation, the well cementation leakage problem of high permeability formation and Karst Cave Formation, and solve deep water top layer section well cementation channelling problem, improve thermal recovery well, the cement mantle packing integrity of hydraulically fractured wells, its use range is more and more extensive.
Since the on-the-spot Cementing application of first time in 1979 foamed cement, Cementing Technology of Foamed Cement application is more and more extensive.Last century the eighties, by improving frothing machine, and strict option table surface-active agent is as suds-stabilizing agent, gas is scattered in whole system with uniform bubble form stable disconnected from each other, produces the foam slurry of excellent property.1987 ~ 1988 years, domesticly carry out 4 vocal imitation skill casing cementings and the test of 12 mouthfuls of sand string foam cementings at Xinjiang Huo Shao Shan Oil-Field, solve the low pressure and easy leaking hydrocarbon zone especially reservoir pressure coefficient oil gas well cementing operation difficult problem that is less than 1.0 effectively.Through years of researches and application, foamed cement technology development and perfect, applies widely in low pressure and leakmess formation well cementation, the well cementation of fractured leakage stratum and the well cementation of deep water anti-channeling.In situ preparation foamed cement mainly contains two kinds of methods: one is mechanical aeration method, and another kind is chemical aeration method.Mechanical aeration method required equipment is more, complex process, and needs well-designed and computer controlled automatic, and field conduct difficulty is comparatively large, costly.And chemical aeration rule does not need various equipment and complicated technical process, directly can add in oil well cement material or water by the foaming agent that can produce nitrogen, have advantage simple to operate and with low cost, be the development trend of foamed cement technology of preparing.
The material being produced nitrogen by chemical reaction is more, as Sodium Nitrite and ammonium chloride react and can produce nitrogen, this reaction is while generation nitrogen, also release along with larger heat, be all widely used in Self-heating fracturing liquid, the thermochemistry displacement of reservoir oil, well wellbore wax removal, oil-well strata de-plugging and uphole equipment cleaning.But, the reaction of Sodium Nitrite and ammonium chloride could can only occur under acidity or higher temperature conditions, and the preparation of chemical nitrogen-charge foam cement slurry is under lower envrionment temperature or room temperature condition, and grout is alkaline medium environment, these 2 are all unfavorable for that Sodium Nitrite and ammonium chloride react.Also foaming agent material will be used in the preparation process of macromolecular material porous plastics, as Cellmic C 121, Diisopropyl azodicarboxylate, dinitrosopentamethylene tetramine, 4, 4`-OBSH, p-toluene sulfonyl hydrazide, 5-phenyltetrazole and trihydrazinotriazine etc., but these materials all must be in a heated condition, generation nitrogen is just decomposed when temperature reaches its decomposition temperature, the preparation being not suitable for chemical nitrogen-charge foam cement slurry is in the condition compared with low ambient temperature or room temperature, these materials mainly azo material simultaneously, its cost is high, and there is toxicity and the potential safety hazard such as inflammable and explosive, the economy of on-the-spot Cementing application cannot be met, safety requirements.Article " is applicable to the ultralow density foam grout of Changqing oilfields well cementation ", and (" Drilling and completion fluids " the 14th volume the 4th phase 27-28 page in 1997) has carried out chemical aeration legal system for foam slurry technical study, develop chemical gas generation agent FCA and FCB, chemical reaction is there is and produces nitrogen in FCA and FCB in grout, add suds-stabilizing agent FCF trap gas simultaneously, thus form mutual disconnected foam slurry, the formula of its foamed cement slurry system is: G level oil well cement+40% drift pearl+88% water+2.5%FCA+1%FCB+4%FCF, grout can be made to be reduced to 0.86g/cm in the density on ground
3.This chemistry fills nitrogen, and first prepare foam slurry technology be utilize drift pearl lightening material that cement slurry density is down to certain limit, and cement slurry density is down to 1.0g/cm by method further that then utilize chemistry to fill nitrogen
3below.If the unit mass nitrogen production rate of foaming agent can be improved, work out a kind of efficient foaming agent, more nitrogen can be filled with in grout, cement slurry density be down to lower, by passing through directly to add chemical gas generation agent in grout, just can by traditional cements pulp density from 1.90g/cm
3be reduced to 1.0g/cm
3below, so not only can decrease drift pearl consumption, and significantly can reduce the cost of foam slurry, it also avoid the high cost adopting mechanical aeration to prepare foam slurry on the other hand, there is advantage easy to use and with low cost.
Foam system is when generating, and the system total area increases, and the energy also corresponding rising of system, belongs to thermodynamic unstable system, and the direction that can spontaneously reduce to energy reduction, the total area is carried out, and namely foam occurs to vanish.For preparing stable foamed cement slurry system, normal needs adds suds-stabilizing agent in grout.Suds-stabilizing agent is mostly some tensio-active agents or surfactant.Tensio-active agent refers to the amphiphile, amphiphilic molecule simultaneously containing polar hydrophilic group, non-polar hydrophobic groups in molecule, can be formed in solution surface (being generally water) and align, thus significantly reduce the surface tension (or interfacial tension) of solvent, and change physical strength and the viscosity of foam film, improve the stability of foam slurry.According to the ionization character of water phase surfactant mixture, tensio-active agent can be divided into the large class of negatively charged ion, positively charged ion, nonionic, zwitter-ion four.At present, the suds-stabilizing agent of foam slurry is mainly sulfonate anionic surfactant type, and it has the performance such as salt tolerant, high temperature resistance, wherein the most frequently used, cost is minimum, what be easy to get most is alkyl benzene sulfonate, particularly Sodium dodecylbenzene sulfonate.But alkyl sodium sulfonate foaming easily but surely steeps difficulty, and froth stability is poor, thus cannot prepare the foam slurry of less dense, and the foam water mudstone of preparation has the deficiencies such as pore texture size inequality, the high and ultimate compression strength of perviousness are low.In addition, the biological degradability of alkyl sodium sulfonate, sodium alkyl benzene sulfonate class suds-stabilizing agent is poor, can cause severe contamination to environment.In recent years, people pay attention to the biological effect of tensio-active agent, toxicological effect and security more, and the research and apply of environment amenable suds-stabilizing agent is more and more favored.
Summary of the invention
