Linear cluster platform well deployment method and device

Abstract

The invention provides a linear cluster platform well deployment method and device. The method comprises the steps: determining platform center plane coordinates and the well mouth arrangement direction of a platform according to plane coordinates of all target points; according to the platform center plane coordinates, the well mouth arrangement direction of the platform, a preset well mouth distance and the number of the target points, preliminarily arranging well mouths; dividing a space around the well mouth into a plurality of target point position areas according to the well mouth arrangement direction, the well mouth position coordinates at the two ends and a preset deviation angle; rearranging the well mouths according to the distribution condition of each target point in each target point position area; determining the well mouth corresponding to each target point according to the rearranged well mouths and the distribution condition of each target point in the target point position area. The method realizes the deployment of the linear cluster type platform well, furthest reduces the anti-collision obstacle bypassing operation, improves the operation efficiency, reduces the operation cost, and is beneficial to the safe tripping-in of well completion and oil extraction pipe columns in the later period.

Description

Technical field [0001] The invention relates to the technical field of oil and gas geological drilling, in particular to a method and device for deploying an inline cluster platform well. Background technique [0002] In the process of oil and gas resource exploration and development, drilling a continuous wellbore from the surface (wellhead) to the location of underground oil and gas resources (underground target points) is the basis for realizing oil and gas resource development. In the early days, affected by drilling technology, only vertical wells could be drilled, that is, the location of the surface wellhead and the underground target were roughly on a straight line. With the development of directional drilling technology, even if the wellhead and the underground target are not in a vertical straight line, directional drilling tools can be used to achieve the target by directional drilling. This type of well is called a directional well. Directional well drilling technolo...

figure 1 The deployment plan of the cluster platform wells is shown, in which, due to the unreasonable deployment plan of the cluster platform wells, the trajectories intersect, that is, the trajectories of the vertical wells and the directional wells intersect. For easy understanding, figure 2 Diameter and directional wells with intersecting trajectories are shown in Fig. There is a greater impact
