Solution Overview
Problem
The high initial investment costs associated with developing marginal or deep-sea oil fields for drilling operations pose a significant challenge, as existing drilling apparatuses are economically inefficient.
Innovation Solution
A drilling apparatus comprising first and second moving modules, drawworks, a wire system with fixing drums, and a controller that adjusts angular velocities based on the weight of the modules to optimize lifting and lowering operations, reducing the need for excessive output and thus initial investment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional drilling apparatus with single moving module is used, then initial investment cost is high, but lifting and lowering capability is sufficient
Solution Approach 1:
The drilling apparatus divides the lifting system into two separate moving modules (first and second moving modules), each with its own drawworks. This segmentation allows each drawwork to handle smaller individual loads, reducing the required output power of each unit while maintaining overall lifting capability, thereby lowering initial investment costs.
Solution Approach 2:
The patent combines two moving modules with separate drawworks into a single drilling system, where both modules work cooperatively to perform drilling operations. This merging allows the system to achieve the required total lifting power through multiple smaller units rather than one large expensive unit, reducing overall investment cost.
2Productivity
If angular velocities of drawworks are not controlled, then operation is simpler, but operational efficiency is reduced
Solution Approach 1:
The controller receives feedback regarding the weight of the first or second moving module and automatically adjusts the angular velocities of the drawworks accordingly. This feedback mechanism enables optimized operational efficiency without requiring complex manual control, as the system self-regulates based on measured conditions.
Solution Approach 2:
The angular velocities of the drawworks are made dynamically adjustable based on the weight of the moving modules. The controller determines appropriate angular velocities in real-time, allowing the system to adapt to varying operational conditions and maximize productivity without excessive complexity.
