Core Applicable Well Types and Operation Scenarios
1. High-Temperature Geothermal Wells and Deep Well Logging Operations
Applicable Conditions: Straight or directional wells with downhole temperatures of 120℃~260℃ and well depths of 1500~5000 meters; neutral or weakly acidic formation fluids, with no severe scaling, borehole constriction or strong corrosion.
Compatible Operations: Geothermal resource exploration, formation parameter measurement (temperature, pressure, resistivity) of deep formations, and high-temperature reservoir evaluation.
2. Perforation and Coring Operations in Low-Sulfur Oil and Gas Wells
Applicable Conditions: Low-sulfur oil and gas wells with H₂S partial pressure ≤ 0.1 MPa and CO₂ partial pressure ≤ 0.3 MPa; well depths ≤ 5000 meters, moderate downhole friction, no extreme high-pressure conditions.
Compatible Operations: Signal transmission and depth control during perforation construction and coring operations in low-sulfur wells; meeting the power supply and load-bearing requirements of conventional logging instruments and equipment.
3. Onshore High-Temperature Exploration Wells and Geological Monitoring
Applicable Conditions: Onshore high-temperature exploration wells, shale gas development wells, with stable formation temperature and pressure, and weak corrosive media; regular wellbore trajectories without high-curvature sections; well depths of 2000~5000 meters.
Compatible Operations: Initial evaluation of high-temperature formations, multi-parameter logging after drilling and completion, and geological dynamic monitoring.
4. Routine Workover and Restart Operations in Shallow to Medium-Deep Wells
Applicable Conditions: Mature old wells with only slight scaling or minor borehole constriction; downhole temperatures ≤ 260℃, with weak corrosion (H₂S partial pressure ≤ 0.1 MPa, CO₂ partial pressure ≤ 0.3 MPa); workover operations focusing on basic detection, simple modifications and high-temperature environment logging.
Compatible Operations: Casing integrity testing of old high-temperature wells, auxiliary scraping operations for shallow wells, and basic logging verification before restart.
