| Résumé : |
Composite drill pipe (CDP) can provide new capabilities for oil and gas drilling operations. CDP is approximately one half the weight of comparable metal drill pipe. The lighter weight drill pipe will provide a capability to substantially increase the depth and lateral reach possible in drill operations. CDP has much higher fatigue resistance than metallic drill pipe. Taking advantage of this capability, CDP has already been used to reopen "thought to be depleted (watered out) reservoirs" through Short Radius (SR) drilling operations. Wiring can be built into the walls of CDP. This provides a capability to simultaneously transmit real time data from the Bottom Hole Assembly (BHA) to the well head and power from the well head down to the BHA.
Recognizing these potentials and the U.S. critical energy requirements, the U.S. Department of Energy, National Energy Technology Laboratory has funded programs to develop and qualify cos-effective composite drill pipe (Contract No. DE-FC26-99FT40262). The program was started in 1999. To date a six inch diameter CDP is being tested for mechanical properties. This CDP, in 30 foot (9.14 meter) sections, is approximately 1/2 the weight of its steel counterpart. The program is currently proceeding with additional laboratory evaluation of this ER/DW CDP and is beginning a "down well" demonstration of the 'in-the-wall' data and power transmission system. As a spin off from the above effort, development of two and one half inch (6.35 cm) CDP, qualified for short radius (horizontal well) drilling, has been successfully used to re-open "thought to be depleted" oil and gas wells. The initial short radius (SR/CDP) drill pipe was used in radii in the 50 (15.2 m) foot range. Recognizing a need to accomplish an even shorter drilling radius, an ultra short radius (USR/CDP) pipe was designed and is being evaluated for drilling radii as small as 30 feet (9.14m). |
