Alcoa在Brunei Shell Petroleum的海上钻井中部署铝合金钻管

Alcoa, the aluminum manufacturer has announced the successful deployment of Aluminum Alloy Drill Pipe measuring 1800 m by its Alcoa Oil & Gas division in the Iron Duke offshore drilling well at Seria in Brunei in conjunction with Brunei Shell Petroleum (BSP) and Alcoa’s project service partner, AMRTUR.

该井被认为是由BSP操作的最复杂的，这是由于三个S形曲线的偏差和一个长度为5,000 m的长度截面。将井在60 m的水中钻至7,485 m的深度。

Shayne Dustin, Senior Well Engineer at BSP stated that in the face of persisting challenges to enhance the scope of drilling area to minimize cost and optimize oil recovery, Alcoa’s light aluminum alloy pipes were identified as a means to address the problems of high drag, high torque, reduced cantilever loading and wearing out of casing. The introduction of the pipes eliminated the need for well design modification at the platform fringes. The Aluminum Alloy Drill Pipe from Alcoa are made up of aluminum tube sections measuring 30 ft and are fastened with steel joints using proprietary thermal connection method. The tubes are produced at the Lafayette facility in Indiana and assembled at its Houston Oil & Gas facility. The pipes are lighter than all-steel pipes by 40%. BSP is planning to deploy the Aluminum Alloy Drill Pipes at other wells in Brunei and Shell is contemplating pipe deployment at a drilling project in New Zealand.
