Definitions

  • the present invention relates to the use of a compound of the general formula ROS (VR 1 R 2 R 3 NH + , a method for cleaning surfaces of boreholes, drilling equipment or cuttings, a method for producing a borehole and a method for producing an oil or a gas.
  • the cement is passed through the tube in an aqueous, liquid form, emerges at the bottom of the casing and hardens between the borehole wall and outer
  • voids or channels will be created in the concrete layer which will increase the stability of the concrete
  • residues of the drilling mud with the cement can form a gelatinous mass which prevents setting of the cement, which also leads to reduced stability of the cement mantle.
  • the actual production tubing which has a smaller diameter than the casing, is installed.
  • a sealing liquid is introduced between the outer wall of the conveyor tube and the inner wall of the casing.
  • the so-called packer-ßuid "' the annulus between Casing and conveying pipe cleaned, in particular, all finely divided solids that still adhere to the casing or conveyor pipe wall must be removed to ensure the performance of the sealing liquid.
  • the selection of the cleaning agent suitable for the above-described tasks also depends on the type of drilling fluid used. In principle, one can distinguish between water-based and oil-based rinses.
  • oil-based rinses are often used, either as so-called “true-oil-muds", ie rinses containing no or only minor amounts, usually below 50% by weight, based on the rinse, dispersed water, or so-called invert muds ", Which contain between 5 and 45 wt .-% of water as a dispersed phase, so form a W / O emulsion.
  • water-based OAV emulsions are known which contain a heterogeneous, finely dispersed oil phase in a closed aqueous phase.
  • Petroleum products such as mineral oils or diesel oils, are usually used as the oil phase. Due to the ever stricter environmental requirements but also synthetic oil phases have been developed recently, containing, for example, esters of certain fatty acids. Drilling muds based on such ester oils are described by way of example in the publications EP-A-0 386 636, EP-A-0 374 671 and EP-A-0 374 672 and show markedly improved properties with respect to their biodegradability and toxicity compared to petroleum products.
  • the cleaning agents like the cement during the cementing process, are pumped down in liquid form through the drill string, emerge at the bottom of the borehole and are flushed upwards in the annular space between the pipe and the borehole wall. In doing so, they dissolve residues of the drilling fluid and solid particles adhering to the surfaces and transport them out of the borehole.
