Cementing operations involve mixing externally supplied water with dry cement powder to prepare the required cement slurry, which is then injected into the annular space between the wellbore and casing. The complete cementing equipment package provides all necessary devices for cementing operations, including slurry mixing, pumping, water supply, cement supply, gas supply, and liquid additives. The package consists of: cementing trucks, cementing skids, deepwater explosion-proof cementing skids, electric explosion-proof cementing skids, constant pressure tanks, liquid additive skids, water supply pump skids, and batch mixing equipment.

Enhanced oil‑production operations are critical measures for ensuring efficient, stable well performance and improving recovery rates, supported by a wide range of robust and practical equipment. Fracturing pump‑injection units deliver power ratings from 600 to 3,000 HP, with high‑pressure fracture stimulation that boosts production in low‑permeability reservoirs; acidizing pump‑injection systems help unblock formation pore channels and enhance flow conditions. Additional equipment—including sand‑control systems, fluid‑blending units, polymer‑blending systems, sand‑mixing rigs, and liquid‑nitrogen injection units—cater to specific operational needs such as sand control, fracturing‑fluid formulation, enhanced displacement efficiency, proppant blending, and completion‑related tasks, thereby supporting the efficient development of oilfields.
