Jaw trajectory design for displacement-controlled profile 2D stretch-wrap bending and part program generation

Method in respect of crude properties, buried depth and drilling technology required,studies were carried out to explore suitable wellbore trajectory designing methods, controlling technique,anti-collision scanning, cementing quality improvement and well life prolongation.

Described hereby is the drilling trace design and construction method thereof with the example of laying the new sewer line in Puchuan Rd, Shanghai.

This thesis combinations two examples on the course of construting the engineering of central heating in Han Dan city to verify the technology has already succeeded in using ,introduces Guided Boring Trenchless Technology,design of pilot hole track,technique of controlling the quality and effect analysis, which can be used as reference for the similar projects in future.
