Solution Overview
Problem
Modular drilling rig systems face challenges in minimizing component count and size while ensuring easy assembly and transportation, often requiring special lifting devices like cranes due to heavy elongated members.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of components is reduced to enable quick assembly, then assembly time is reduced, but the size and weight of individual components must be kept small for transportation by normal vehicles
Solution Approach 1:
The base structure is divided into multiple separate elongated members (first elongated member, second elongated member) that can be transported independently by normal vehicles. These members are then connected using a cross beam to form the complete base structure, enabling quick assembly without requiring heavy components that would need special lifting equipment.
2Strength
If elongated members are made heavy to provide sufficient structural strength, then structural strength is improved, but special lifting devices like cranes are required for handling
Solution Approach 1:
The base structure is segmented into multiple lighter elongated members that can be handled by normal vehicles without requiring cranes or special lifting equipment. Each member maintains sufficient structural strength for its function while the overall base structure achieves the required strength through the combination of multiple members connected by cross beams.
Solution Approach 2:
The displacement system serves multiple functions: it positions the elongated members during assembly and also provides lifting capability for the mast and other heavy components, eliminating the need for separate crane equipment while maintaining the ability to handle heavy loads.
3Stability of the object's composition
If the base structure is designed to surround the well centre entirely for stability, then stability is improved, but access to the well centre is blocked
Solution Approach 1:
The base structure is designed with an asymmetric C-shaped configuration where the first and second elongated members extend parallel to each other with spacing between them, leaving the well centre area open and accessible. This asymmetric design provides sufficient stability for drilling operations while maintaining clear access to the well centre for drilling activities.

AI summary
The invention relates to a modular drilling rig system comprising multiple components, which system is transfigurable between a transport mode and an operational mode, and comprises: a. a drilling rig mast which is positionable in a vertical orientation; b. a base structure adapted to be positioned on a surface near the well center to support the drilling rig mast thereon, wherein the base structure comprises two elongated members that are connected to each other by a cross beam; c. a displacement system to displace the drilling rig with respect to the surface in a horizontal direction; wherein the displacement system is configured to displace the two elongated members of the base structure together in order to displace the drilling rig, and is configured such that the two elongated members can be displaced with respect to each other when the two elongated members are not connected to each other.
