摘要
The invention relates to a polymeric sea water-based fluid containing potassium chloride for onshore and offshore well drilling, wherein the fluid is designed for drilling formations with a low or medium clayiness, but is not limited to this type of well formation if the circumstances justify it. In the preferred embodiment of the invention, the fluid is used for drilling the clayey zones with the high-performance, polymeric sea water-based fluid containing potassium chloride. The present invention fulfills the rheological technical requirements for achieving cuttings transport and suspension, the control of the filtering, lubricity and inhibition of clays. The fluid according to the invention is mainly composed of sea water and polymeric liquid products of new-generation technology, which are high-performance, and which are simple to prepare and quick to homogenise, thereby minimising the logistics of ships and ensuring the continuous supply of the fluid volume during the drilling in order to prevent non-productive times, thereby guaranteeing the lowering of the casing pipes in the estimated time, without operational logistical delays.
