The invention provides a well deployment method and device for an in-line cluster platform. The method includes: determining the center plane coordinates of the platform and the wellhead arrangement direction of the platform according to the plane coordinates of each target point; Preliminary arrangement of wellheads based on wellhead arrangement direction, preset wellhead spacing and number of target points; divide the space around the wellhead into multiple target points according to the wellhead arrangement direction, wellhead position coordinates at both ends and preset offset angles Location area; rearrange the wellhead according to the distribution of each target point in each target location area; determine the corresponding position of each target point according to the rearranged wellhead and the distribution of each target point in the target location area The wellhead can realize the deployment of in-line cluster platform wells, which can minimize the anti-collision and circumvention operations, improve the operation efficiency, reduce the operation cost, and facilitate the later completion and safe running of the oil production string.
Description
technical field [0001] The invention relates to the technical field of oil and gas geological drilling, in particular to a deployment method and device for an in-line cluster platform well. Background technique [0002] In the process of exploration and development of oil and gas resources, drilling a continuous wellbore from the surface (wellhead) to the location of underground oil and gas resources (underground target point) is the basis for realizing the development of oil and gas resources. Affected by drilling technology in the early days, only vertical wells can be drilled, that is, the surface wellhead position and the underground target point are roughly on a vertical straight line. With the development of directional drilling technology, even if the wellhead and the underground target point are not on a vertical line, directional drilling tools can be used to achieve the target. This type of well is called directional well. Directional well drilling technology prov...
