Study and Application of a Non-Bromide, Environmentally Friendly, High-Temperature Resistant, and High-Density Solid-Free Completion Fluid
Global oil and gas exploration has expanded to deep wells (>4500 m), ultra-deep wells, and complex environments (e.g., HPHT and permafrost). Such conditions impose stringent requirements on completion fluids: wide-temperature stability (-30 to 220°C), high density (≥1.70 g/cm3), and environmental friendliness. Tradit...
