Directional well trace design method and system for offshore exploration and electronic equipment

Abstract

The invention relates to a directional well trace design method and a system for offshore exploration and electronic equipment. The design method comprises the following steps: S1, receiving design parameters of a directional well trace design, S2, performing arithmetical processing according to the design parameters to obtain target parameters of the directional well trace design, and S3, outputting a directional well trace according to the target parameters, wherein the design parameters comprise a wellhead coordinate of a directional well, a target spot coordinate of a first target layer, atarget spot coordinate of a second target layer and well bottom design depth of the directional well under a geocentric coordinate system. The directional well trace can be obtained quickly; the design speed and efficiency of the directional well trace are improved; a time loss and an error due to repeated modification of target spots are greatly reduced; an effect of improving quality and efficiency is achieved; and a project design scheme can also be verified before offshore drilling so as to timely find problems and improve well drilling effectiveness.

Description

technical field [0001] The present invention relates to the technical field of exploration drilling, and more specifically relates to a method and system for designing directional well trajectory and electronic equipment for offshore exploration. Background technique [0002] With the continuous development of offshore oil and gas exploration and development to new areas, new formations and deep layers, the traditional design method of vertical wells for exploration can no longer meet the actual production needs of complex geological structures in new deep areas, and the design requirements for directional wells are even greater. There are many, higher requirements, and the design time is more urgent. [0003] This poses new challenges to the design of directional wells in offshore exploration—it is urgent to develop a set of fast and high-precision directional well design systems and methods to achieve the purpose of quickly obtaining directional well trajectories.

Problems solved by technology

[0004] At present, for the design of directional well trajectory, the directional well trajectory design is usually carried out by adopting the method of man-made fitting in the work area. This design method is not efficient in design. A substantial increase in time cost and a substantial increase in the number of trials and errors, and the accuracy cannot be guaranteed
