Abstract
In the process of deep shale gas horizontal well drilling, rotary guidance tools not only adjust the borehole trajectory, but also transmit downhole geological and engineering data transmission. These advantages provide convenience for deep shale gas development, however, when the wellbore temperature exceeds 135°C, it is easy to cause the signal loss of rotary guidance tool. In this paper, based on the perspective of solid-liquid phase change and heat absorption to reduce the bottomhole temperature of drilling fluids, we prepared a y cucurbit[n]uril eutectic compound (CB[n]), which was structurally confirmed by infrared and nuclear magnetism, and evaluated the phase change temperature and latent heat value of CB[n], which was determined to have the potential to be used as a cooling agent for deep shale gas drilling fluids.
