With the increasing demand of the lateraldrilling and slim hole drilling, the coiled tubing (CT) operating technique will play a great role in horizontal well drilling, well workover and completion.
To make lateral reservoir prediction by using synthetic acoustic logging section before the development of Aershan oil field is an important measure for reducing the drilling failure.
