Description
Technical field
The present invention relates to a kind of oil well cement additive, say further, relate to a kind of oil well cement additive that prevents hydrogen sulfide corrosion, and its preparation method and application.
Background technology
In recent years, in the exploitation in some gas fields, oil field, run into a large amount of hydrogen sulfide (H
2S) obnoxious flavour, Sinopec and CNPC find not only to contain Sweet natural gas in the marine facies gas reservoir in the exploration of Sichuan Basin marine bed, and contain H
2S, CO
2The corrosion poisonous gas.The H in general phosgene field
2S content reaches 180g/m
3, CO
2Content reaches 80g/m
3Be positioned at the H of the Luojiazhai gas field of Kaijiang
2S content reaches 150g/m
3, CO
2Content reaches 100g/m
3, from " 12.23 " Serious Accident that No. 16 wells of Luojiazhai gas field sieve family in 2003 occur, leak out to No. 2 wells of sieve family in 2006 and contain H
2The Sweet natural gas of S, twice accident have all caused the very big destruction of life, property and environment on every side.Accident analysis shows the accident of sieve family 2 wells and cementing quality is poor that much relations are arranged.
The Main Function of oil well cement annulated column is to support and hang and the protection borehole wall, and shutoff bottom fluid prevents the corrosion of layer cross flow and sleeve pipe, plays simultaneously packing oil, gas, water, supports sleeve pipe and protective casing, extends the effect in Oil/gas Well life-span.Be subject to if the cement annulated column is Behavior of Hardened Cement Paste corrosion and the destruction that the corrosion of local water, gas can cause and accelerate sleeve pipe, reduce the oil well life-span, bring great hidden danger to safety in production.Hydrogen sulfide is breakneck toxic substance, and the water-soluble and moisture of gaseous state is dissolved in the H in moisture
2S corrodibility is stronger.H
2S can destroy all compositions of Behavior of Hardened Cement Paste.H
2S and Behavior of Hardened Cement Paste hydrated product react and generate CaS, FeS, Al
2S
3, H
2Generate Ca (HS) when S content is large
2, wherein FeS, Al
2S
3Deng being the material that there is no cementing properties, cause cement annulated column porosity to increase, when the cement annulated column is subject to H
2After the S corrosion, sleeve pipe loses one protective barrier and is corroded.
Research emphasis both domestic and external is placed on the material of oil well casing, oil pipe and instrument before this.More or less have close related with cementing quality but the gas well that occured in China is out of control.Although domesticly build consensus for the importance of marine facies high sour gas well safety at cementing quality, due to H
2S toxicity is large, and the danger of experimental study is larger, and is domestic to H
2Research and the anti-H of cement annulated column of S corrosion cement annulated column
2The exploitation of S corrosion admixture yet there are no relevant report.
External Russia once ran into 80～150 ℃ of well temperature, H
2S content is up to 25% hole condition, and studies successfully a kind of anti-H
2S corrosion add weighted cement, claim Ц Т y К 120 cement.But the shortcoming of this cement is that the organic materials paraffin class in cement dissolves even volatilization at the wax of the slightly high 80%wt of ball milling temperature content.
In sum, research and develop out and can effectively prevent H
2Gaseous corrosion oil well cement additive and the technological methods such as S, improving the grout anti-corrosion capability is the technical barrier that needs to be resolved hurrily at present.
