摘要：

Tension load and torque at the well head can be substantially reduced by the use of a composite drill pipe. This is because advanced composites have a set of unique properties of high stiffness and strength coupling with light weight. Therefore in horizontal drilling the reach distance can be extended 40% from 7.62 to 10.67 kilom (25,000 to 35,000 ft) over the conventional steel drill pipe. This increase in reach offers an enabling capability in offshore E&P operations that allows oil and gas wells to be developed from fewer and smaller platform structures. Substantial cost savings can be realized. This is extremely important in deepwater operations where platform weight and rigidity are major design considerations. Additionally, by replacing a steel drill string with a composite drill pipe, it would permit the deployment of an electromagnetic telemetry system in downhole logging while drilling (LWD) operations. This could potentially allow an increase of data transmission rate by several orders of magnitude over the current technology utilizing the pressure pulse in mud stream.
