Definitions

  • the present invention relates to the use of the inventive polyether-containing copolymers in the cementing of boreholes.
  • various types of organic compounds are used.
  • the components of one class which is referred to collectively as superplasticizers, liquefy the aqueous cement compositions to obtain more free-flowing compositions. Controlled flowability is desirable in order that the aggregate used in mortars or in concrete does not separate from the cement paste.
  • these superplasticizers allow cement compositions to be produced using lower water/cement ratios, such that compositions with desired consistency are obtained, and which often have better compressive strength profiles after setting.
  • a specific field of use in this context is the cementing of boreholes in the development, exploitation and completion of underground mineral oil and natural gas deposits, and in deep bores. This is of significance especially in the field of mineral oil and natural gas exploration, since cement slurries which consist essentially of cement and water, in the cementing of the boreholes, are pumped through the annular space between what is called the casing and the borehole wall.
  • condensation products naphthalenesulphonate/formaldehyde condensation products, lignosulphonates, polysaccharides, hydroxycarboxylic acids and salts thereof, and
  • PCEs polycarboxylate ethers
  • superplasticizers are often multicomponent products, especially copolymers of polyalkylene glycol monovinyl ethers and unsaturated dicarboxylic acid derivatives.
  • EP 0 736 553 A2 describes those copolymers which consist at least of three comonomers, namely of an unsaturated dicarboxylic acid derivative, a polyalkylene glycol monovinyl ether, and additionally a hydrophobicizing structural unit, for example an ester unit.
  • the third structural unit may also be a polypropylene oxide or polypropylene oxide/polyethylene oxide structural unit.
  • copolymer with two monomer components is supposed to mean that the copolymer is obtainable by copolymerization of the two monomer components a) and b).
  • the component comprises preferably a) acrylic acid, methacrylic acid, crotonic acid, isocrotonic acid, a Ci-5-alkyl ester or an alkali metal salt thereof, or a mixture thereof.
  • Said copolymer contains suitably 30 to 99 mol% of component a) and 70 to 1 mol% of component b), preferably 40 to 95 mol% of component a) and 60 to 5 mol% of component b).
  • Component b) of the copolymer suitably comprises a vinyl ether, allyl ether or isoprenyl ether. It preferably has a molecular weight of 500 to 15 000 g/mol.
  • the copolymer itself preferably has a molecular weight of 1000 to 250 000 g/mol.
  • the -(CmH2mO)x(CnH2nO)y- group of component b) in said copolymer preferably comprises a (block/stat)copoly(ethylene/propylene) glycol group or a (block/stat)copoly(propylene/ethylene) glycol group. It more preferably comprises between 20 and 250 ethylene oxide units and between 0 and 60 propylene oxide units.
  • component a) comprises acrylic acid and/or sodium acrylate
  • the ratio of the components is approx. 87.5 mol% of acrylic acid (partly as the sodium salt) and approx. 12.5 mol% of vinyloxybutyl polyethylene glycol (with a molecular weight of approx. 5800 g/mol).
  • the molecular weight of the copolymer is preferably approx. 45 000 g/mol.
  • Said copolymer is known by the Liquiment® 5581 brand (CAS No. 250591 -84-5).
  • the copolymer which has preferably been prepared by means of free-radical copolymerization, is more preferably used as a powder. It is suitably used in an aqueous cement slurry, preferably together with commercial fluid loss additives, retarders, accelerators and/or defoamers.
  • Liquiment® 1641 copolymer of hydroxybutyl vinyl ether and maleic anhydride (monoester with methyl polyethylene glycol), product from BASF Construction Polymers GmbH
  • Liquiment® 2641 copolymer of vinyloxybutyl polyethylene glycol, acrylic acid and maleic anhydride, product from BASF Construction Polymers GmbH
  • Liquiment® 5581 has a much smaller retarding effect than the two other, structurally similar plasticizers.
