For the hydraulic drive centrifuge, an advanced hydraulic control technology is adopted. Hydraulic pumps and motors are used to realize stepless speed regulation, providing the advantages of stable performance and smooth speed regulation. It can effectively remove 2μm-10μm harmful solid, and suitable for drilling fluid treatment, drilling waste treatment, etc.

The traditional method of producing nitrogen in liquid nitrogen stations and transporting and injecting by transport vehicles is inconvenient and costly. On-site nitrogen production by special nitrogen production vehicles has the advantages of convenience, low investment, safety and reliability.

The ZlCQ series vacuum centrifugal degasser is widely used in domestic drilling. When the impeller rotates in the shell, it can not only discharge the liquid, but also stir the liquid to make the gas overflow. It has compact structure and low power consumption.

The S340bk vibration sieve is of a new type. It adopts four large-area plate and frame screens arranged up and down to realize mud grading filtration and improve the throughput and treatment effects.

➣ Used for centralizing and centring of the casing during completion operation of high-angle deviated holes and horizontal wells; the sliding friction generated between the lowered casing and the borehole wall can be changed into rolling friction, effectively reducing the friction caused during casing lowering.

➣ In order to improve the cementing quality between cement and the formation (second interface), our company develops “oversized mud cake remover”. It adopts unique design and materials, and is formed with unique process. For the scraper, high-elasticity manganese steel wires are adopted, woven and inter-embedded to realize 360° all-side scraping. The steel bodies at the both ends are centralized, and the blocking of swirl channels is prevented. The model can be selected according to the enlargement rate to ensure the effect. It is a unique product at home and abroad currently.

➣ Divided into the rigid centralizers with straight blades and spiral blades;➣ Applicable for the horizontal cementing of high-angle deviated holes;➣ The type with spiral blades effectively improves displacement efficiency;➣ Stream-lined structure, for easy casing lowering

Standard plugs are applicable for various float collars and float shoes. The anti-rotation mechanism is designed for the anti-rotation plugs, improving drilling-off speeds greatly. Self-locking plugs are advanced technically and can be used safety; the product performance can reach the advanced level in China.
