Definitions
- the present invention is a graft copolymer, a process for its preparation and its use.
- Copolymers even in grafted form, are well known and are used because of their specific monomer composition in a variety of applications.
- copolymers are also frequently used as water retention agents, which are also referred to as fluid loss additives.
- a special field of application in this context is the cementation of boreholes in the development of underground oil and gas deposits.
- Fluid loss additives or water retention agents are compounds which reduce the release of water from a cement slurry. This is particularly important in the field of oil and natural gas exploration, as cement slurries, which essentially consist of cement and water, are pumped during the cementation of the boreholes through the annulus between the so-called casing and the borehole wall. In this case, quantities of water can be released from the cement slurry to the subsoil formation. This is particularly the case when the cement slurry flows past porous rock layers during well cementing. The alkalized water from the cement slurry can then swell clays in the formations and form calcium carbonate precipitates with carbon dioxide from the natural gas or petroleum. These effects reduce the permeability of the deposits and, as a consequence, the production rates are negatively affected.
- the cement slurry does not solidify due to the release of water to the porous subsoil formations and thus becomes permeable to gases as well as to liquid hydrocarbons and water. As a result, this leads to the escape of fossil fuels through the filled with porous cement annulus. It is therefore for some time continuously striving to reduce such water loss of the cement slurry used to a tolerable minimum.
- EP 0 116 671 A1 describes a cement slurry for deep wells which, with its content of copolymers, is intended to reduce water loss.
- An important component of the copolymers used are acrylamides and in particular acrylamido-methyl-propane sulfonic acid (AMPS).
- AMPS acrylamido-methyl-propane sulfonic acid
- the cement slurries should contain between 0.1 and 3% by weight of the suitable copolymers.
- Borehole cementing and a composition suitable for this purpose is the subject of EP 1 375 818 A1.
- a polymer additive is used which in addition to AMPS additionally contains maleic acid, N-vinylcaprolactam and 4-hydroxybutyl vinyl ether.
- the water-soluble copolymers according to US Pat. No. 6,395,853 B1 also contain, among other things, the building blocks acrylamide and AMPS.
- the building blocks acrylamide and AMPS At the forefront of this right is a process for reducing the loss of water in a slurry used to extract oil. Particularly noteworthy in this context are the drilling Lochzementtechnik and completion and the previous process steps preceding borehole sludge.
- the focus of US 4,700,780 is a method for reducing the loss of water in cementitious compositions which also include defined salt concentrations.
- the water retention agent is in turn a polymer or polymer salt of AMPS, in which case the building blocks styrene and acrylic acid still have to be present.
- US Pat. No. 6,855,201 B2 discloses a cement composition consisting of a hydraulic cement component, water and a polymeric fluid loss control additive.
- the copolymer is based on AMPS, the calcium salt of maleic acid, N-vinylcaprolactam and 4-hydroxybutyl vinyl ether. This polymer is added to the cement composition in amounts between 0.1 and 2% by weight.

- a suitable acrylamide is u. a. AMPS mentioned.
- Patent EP0505230 describes silica particles in a polymer matrix having film-forming properties.
- the silica particles are first functionalized with a silane, although these are double bond-containing silanes. Subsequently, various monomers are grafted onto these silanized silica particles.
- the monomers mentioned are alkyl (meth) acrylates, unsaturated monocarboxylic acids, aromatic vinyl compounds, dienes (butadiene, chloroprene), vinyl acetate, styrene.
- polybasic, unsaturated carboxylic acids or unsaturated sulfonic acids (eg AMPS) in proportions of up to 15% by weight. The use of these film-forming polymers is limited to the paint industry.
- a coating consisting of a radical-curing monomer or oligomer and a surface-treated inorganic particle is known from WO
- the particle is coated with a fluorosilane and a crosslinkable silane, wherein as crosslinkable silanes and double bond-containing silanes are called.
- AMPS is mentioned as a suitable monomer.
- DE102005000918 describes a process for the preparation of an aqueous multicomponent dispersion.
- This dispersion is prepared by radical polymerization of various monomers in the presence of inorganic particles and a dispersant.
- the monomer mixture contains at least one epoxide group-containing compound.
- additional monomers also unsaturated silanes and sulfonic acids are mentioned.
- the object of the present invention is to provide a novel graft copolymer which is based on the proven monomer building blocks, but by varying the grafting partners leads to a property profile which shows significant improvements especially in the presence of divalent salts and at very high temperatures.
- this graft copolymer shows a significantly better performance as a water retention agent, with its advantages coming into play particularly under demanding conditions. Due to its monomer building this graft copolymer can be produced very economically. Especially under saline conditions it has been found that the fluid-loss effect of the graft copolymers of the invention over the hitherto known copolymers has significant advantages.
- silica constituent in component a it has proved advantageous in the context of the provisional invention for this silica constituent to be based on an aqueous colloidally disperse solution of amorphous silicon dioxide (SiO 2). Particularly suitable for the subsequent reaction with an unsaturated silane, so-called nano- and microsilica has been shown.

It has also been found to be advantageous if the proportion of component a) in the graft copolymer of 10 bis 90 wt .-% and in particular from 40 to 70 wt .-% is. The proportion of component b) in the copolymer should be from 10 to 90% by weight and in particular from 30 to 60% by weight.
