Measurement while drilling instrument

As is well known, one of the main functions of Measurement While Drilling (MWD) is to measure wellbore geometry. Directional drilling engineers adjust the actual drilling trajectory based on real-time inclinometer data to achieve the desired design trajectory.

Depending on drilling conditions, our company’s MWD products are mainly divided into two categories: one is an MWD with excellent high-temperature resistance and vibration resistance; the other is an MWD with dynamic continuous inclinometer measurement and real-time transmission capabilities.

The surface system of oilfield drilling measurement instruments is the core platform for realizing geological guidance and real-time monitoring of drilling parameters. It consists of two modules: surface data processing instruments and software processing system.

Electromagnetic resistivity logging technology accurately obtains formation resistivity by measuring the propagation characteristics (phase difference and amplitude attenuation) of electromagnetic waves during oilfield operations. Its core functions include geological location, fluid identification, reservoir evaluation, and engineering risk early warning.

**Multi-Depth Resistivity Detection**

By emitting 2MHz/50kHz electromagnetic waves and utilizing phase difference/amplitude attenuation measurements, resistivity curves at eight different detection depths (0.1-5m range) can be obtained, enabling fine radial evaluation from intrusion zones to undisturbed formations.

**Azimuth Imaging Capability**

Eight-sector azimuth gamma and resistivity imaging technology can identify formation interfaces (such as oil-water interfaces and

Near-bit geological steering systems are mainly used to solve the problems of traditional geological steering instruments where the geological parameters and trajectory parameters are far from the drill bit and the measurement parameters are lagging, which makes it easy for the drilling trajectory to deviate from the reservoir and the effective reservoir drilling speed is low.

Intelligent rotary steerable drilling systems are drilling systems capable of providing guidance in real time during the drilling process, representing a significant revolution in directional drilling technology. Rotary steerable drilling offers advantages such as low friction and torque, high drilling speed, low cost, short wellbore construction cycle, smooth wellbore trajectory, and ease of adjustment and control. It can also extend the length of the horizontal section and is considered the future direction of modern directional drilling technology.
