3. Application Results & Performance Highlights
Ultra-high Drilling Efficiency, Significantly Shortened Drilling CycleThe average ROP of this operation reached 18.2m/h, far exceeding the conventional operation level of the same formation in the block. It completed 692m of footage with only 38 hours of net drilling time, greatly shortening the single-well drilling cycle and significantly reducing the customer's comprehensive operating cost.
One-trip Drilling for Well Completion, No Abnormal Working Conditions Throughout the IntervalThe bit was run in hole at 2790m, and tripped out after well completion at 3482m. It completed the operation of the target interval in one trip, with no intermediate trip out and no abnormal damage to the bit, which fully reflects the excellent wear resistance, impact resistance and formation adaptability of the product.
Customized Design for Formation Adaptation, Outstanding Stable Drilling PerformanceThe SD6431 bit optimizes the cutter layout, crown profile and hydraulic structure according to the lithological characteristics of the Taiyuan Formation. It maintained a stable drilling state throughout the operation, with no abnormal working conditions such as bit bouncing or weight stacking, and the well completion quality fully meets the industry standards.
4. Case Summary
The successful application of the 6-1/2" SD6431 PDC bit in Well Su 25-13-13X perfectly achieved the customer's core operation goals of "drilling speed and efficiency improvement, one-trip well completion".
The core advantages of high ROP, long service life and high stability demonstrated by the product in the Taiyuan Formation can provide mature model selection reference and efficient customized solutions for oil and gas well drilling operations in the same type of formation in the same block.
