Embodiment Construction
[0051] The present invention will be further described below in conjunction with drawings and embodiments.
[0052] refer to figure 1 As shown in the flowchart, the present invention provides a three-dimensional directional well trajectory design and control parameter discrimination method, divided into seven steps of P1, P2, P3, P4, P5, P6, P7, according to P1 to determine the three-dimensional directional well design required The parameters of the well are known, and then, according to the P2 step, the known parameters of the 3D directional well determined in P1 are respectively brought into the calculation formulas of the parameters of the inclined plane arc trajectory design, and the target parameters of the 3D directional well design trajectory are calculated, according to P3 The first step is to use the relative coordinates of the target point and the horizontal projection of the full-bending midpoint to judge the target azimuth angle variable, and then calculate the 3D ...
