Apparatus and Method for Measuring Inclination in Subsea Running, Setting, and Testing Tools |
| 摘要 |
A system for jetting a borehole in a seafloor, the system including a tubular, and a jetting tool inserted into the tubular and having an end from which fluid is selectively discharged to excavate the borehole. An electrical inclination sensor is attached to the stem of the tubular, and is in communication a transmitter. A receiver is positioned proximate the sea surface and is in communication with the transmitter through the fluid in a drill pipe, so that when the jetting tool is excavating the borehole, an inclination of the tubular is sensed by the inclination sensor, which inclination is communicated from the transmitter to the receiver. |

1. A system for jetting a borehole in a seafloor, the system comprising:
a tubular; a jetting tool inserted into the tubular and having an end from which fluid is selectively discharged to excavate the borehole; an electrical inclination sensor attached to the stem of the tubular; a transmitter in communication with the electrical inclination sensor; and a receiver proximate the sea surface and in communication with the transmitter through the fluid in a drill pipe, so that when the jetting tool is excavating the borehole, an inclination of the tubular is sensed by the inclination sensor, which inclination is communicated from the transmitter to the receiver. |
