| 摘要 |
Apparatus and methods are provided for improved communications, preferably acoustic communications, to convey real time data during drilling rig related operations between downhole instrumentation and surface instrumentation. Specifically, the apparatus and methods address issues with the transmission of data to the surface, including reflective and refractive interference caused by equipment used in the drilling operation, such as surface slips and pack off material. In some embodiments, a surface instrumentation configuration for drilling rig related operations is provided in which data transmission may be improved as a result of the placement of the surface communications instrumentation. For instance, in some embodiments, the apparatus is comprised of a surface slip including a communications instrument, such as an acoustic receiver. In some other embodiments, the apparatus is comprised of a pack off material including surface instrumentation, such as an acoustic receiver. The methods utilize the apparatus for communication with the downhole instrumentation.
