| titleOfInvention | WITHOUT SAFETY INVERT EMULSION DRILLING SOLUTIONS AND METHODS FOR DRILLING WELLS STEM |
| abstract | Invert emulsion drilling fluid with good rheological properties at high temperatures and pressures and method of its use when drilling boreholes. One form of implementation of drilling fluids of the present invention does not contain organophilic clays, lignites and calcium chloride, but contains glycerol in the internal phase and a suspending agent, including a combination of dimeric fatty diamines and short-chain acids, such as citric acid. In one embodiment of the present invention, the base oil for the emulsion is paraffin and / or mineral oil. These drilling fluids have good rheological properties, including good suspension of drill cuttings. |
