As a certified drilling contractor, On Point Directional Drilling & Trenching is ready to tackle your next jobwhether it’s a large-scale construction project or a small utility repair.
The models in this project uncover the interaction between the side force and the tilt angle. With more than 15 years of experience in underground directional drilling, trenching and boring, Matt and his team can handle projects of any scale and complexity. The Point-The-Bit model shows that the tilt angle is the main factor that controls the walk direction for the Point-The-Bit. One model is used to calculate the Point-The-Bit. The stronger the drill pipe, the higher the efficiency of directional drilling. The models show that the side force is the main factor to influence the walk direction of the drill bit for Push-The-Bit. Two models, one model with rigid drill pipe assumption and one model with elastic drill pipe, are used to analyze Push-The-Bit. The DLS of the wellbore can be calculated with the side force and the tilt angle. The side force and tilt angle can be calculated when the BHA is in static force balance status. In the models, the BHAs are assumed to be a continuous beam supported by the drill bit, the pivot pad and the stabilizer. Utilizing the offset motor angle allows the driller to effectively point the drilling bit in an offset direction, thus creating a build in the well bore. Three new analytical models are developed based on force analysis in this project in order to calculate the side force and DLS for Push-The-Bit BHA and Point-The-Bit BHA. It is imperative to calculate the two factors to predict the drilling direction. Third, The direction (Degrees from North) at the survey station. Second, The measured depth (AHD) of the survey station. First, The position of the initial, reference point.

The side force and the tilt angle of the drill bit also influence each other. How To Determine The Coordinates Of Directional Survey stations. In directional drilling, both the side force and the tilt angle influence the dog leg severity (DLS) of the wellbore.
