Embodiment Construction

[0016] As mentioned above, when drilling, it is necessary to maintain continuous communication with downhole equipment. When drilling or lifting downhole equipment (such as drill pipe) in and out, the elevator or top drive moves up and down and moves the drill string components. At this time, it is advantageous to provide communication from the drill string telemetry system to the computing device. According to one embodiment, a wireless communication system is required, such as providing a wide area local area network (WLAN) to allow communication while adding a drill pipe. The WLAN transmitter and receiver can be arranged to enable good data transmission at each location of the rig. This is challenging because rig towers are usually constructed of steel. It should be understood that other wireless standards and frequencies may also be used, such as, for example, Bluetooth.

[0017] The connection problem can be solved by installing the leakage feed vertically along at least ...

Abstract

A drillstring communications system includes one or more pipe segments, a communication sub coupled to the pipe segment that includes a communication sub antenna, and a leaky feeder antenna in communication with the communication sub antenna.

Description

[0001] Cross reference of related applications [0002] This application claims the rights of U.S. Patent Application No. 14 / 446987 filed on July 30, 2014, and the entire content of U.S. Patent Application No. 14 / 446987 is incorporated herein by reference. Background technique [0003] The exploration and production of hydrocarbons usually requires drilling deep into the surface. Boreholes provide access to geological formations that may contain oil or gas reservoirs. [0004] Drilling operations require resources such as drilling rigs, drilling workers, and support services. These resources can be very expensive. In addition, these costs will be higher if the drilling operation is performed offshore. Therefore, it is necessary to control costs through effective drilling and drilling. [0005] The efficiency can be measured in different ways. In one method, efficiency is measured by how fast a hole can be drilled. However, drilling the hole too fast can cause problems. If the dr...
