The Design Of Directional Well's Well Trajectory And Implementation By Software

Drilling technology is fast moving forward in these years with improvement of its engineering and equipment, and directional Well draw our attention with its importance and practical applicability. This paper is pulling for further works as listed blew on the shoulders of forerunners.According to the design principle of well trajectory, this paper build models as listed here, Five stops-'vertical-aggrandize-stable-drop-stable', Three stops-'vertical-aggrandize-stable', catenary and parabola. Elicit computational formula of the undetermined parameter; study the ideas of design and Algorithm steps. Based on this we compose the VC++ program which can meet the basically requirement of wellbore trajectory's design through adjusting parameter value, so that we can obtain well's tracing image and key points'parameter table.Regarding problems in well trajectory's design project, this paper present methods making parameters diversification to solve. The users can choice different but already known parameters then can get calculation formula for undetermined parameter. Better performance can be seen in practical use because of it offers more choices for undetermined parameter, and can fulfill different assignments.This paper discusses the ubiquitous drift problem compositively in practical drilling, finds that rules of azimuth drift and its characteristics can impose all parameters. With treating the 3d drift trajectory as an ensemble, can get better parameters for key points by the Constraint equations, and better design of directional drift trajectory.This dissertation study the clinometers calculation indepthly, build computational mathematics models for it, present methods of figuring out the location of measuring point by surveyed inclinometer data, then can gain shapes of well's body at practicing scene. At last this solution obtains a better designs ketch after combining with trajectory's mathematical model.
