FLUID PRESSURE PULSE GENERATING APPARATUS WITH PRESSURE COMPENSATION DEVICE AND PULSER ASSEMBLY HOUSING |
摘要 |
A fluid pressure pulse generating apparatus with a pulser assembly having a pulser assembly housing enclosing a pressure compensation device. The pulser assembly housing includes an interior wall with a plurality of primary apertures therethrough and an exterior wall with a plurality of secondary apertures therethrough, the exterior wall overlying the interior wall. The primary and secondary apertures are in fluid communication with a pressure compensation mechanism in the pressure compensation device such that drilling fluid contacts the pressure compensation mechanism for equalization of pressure of a lubrication liquid contained inside the pulser assembly housing with pressure of the drilling fluid when the fluid pressure pulse generating apparatus is positioned downhole. |
