Wireless MWD Measuring System

SMWD wireless MWD system is developed by China's first batch of directional well experts of wireless MWD systems. The R&D personnel are the maker as well as the user. Every design condensed their deep understanding on the spot, with independent intellectual property rights. This product is reliable and durable with simple operation system, convenient maintenance and strong adaptability.

Application Scope

Apply to the real-time monitoring of the well path during directional drilling or horizontal drilling in petroleum, geology, coal, water conservancy industries etc.

Product Features

Simple Structure, easy to use: The instrument is with modular design. No on-site adjustment and easy to connect.

Instrument outer diameter design, high applicability: Adopt Φ 45 outer diameter design, which is suitable for slim-hole window well.

Less accessories, reduce cost:  The auxiliary parts of the instrument only need some o-rings and centralizers, which are at low cost.

Simple operation, convenient maintenance: Just need to pay attention to the replacement of seriously worn centralizers or o-rings before use.

Long durability, save time and effort:  The maintenance interval of pulse and electromagnetic valve is over 500 hours, which is convenient for field use.

Suspension design, easy to locate: Adopt the suspension design, thus the key base is convenient and the measuring data are quite reliable.
