Background

Oilfield mud pressure measurement mainly occurs in fracturing, acidizing, cementing and other scenarios. Oil well stimulation (fracturing and acidizing), logging and oil well development (casing and cementing) are important oil and gas processes measured and monitored by pressure sensors. The oil field operation environment is very harsh, and has extremely high safety performance requirements. It is required that the pressure sensor used in the oil field has a solid structure. Whether on land or at sea, it must provide accurate and reliable performance at the same time, and consider the use safety performance.

Application

The oil field mud pressure sensor series of Changsha Tianhe Electronic Equipment Co., Ltd. is widely used by oil and gas companies to measure the pressure level changes in the medium circulation system. Specific applications are as follows:

1. Petroleum mud logging

Connect a series of pressure sensors to the drilling equipment and install them on the special equipment to monitor or record the activities of the drilling rig.

2. LWD and MWD

The pressure sensor continuously measures the pressure or flow of drilling fluid, and timely adjusts the mixture or pressure level to keep the drilling rig running, so as to prevent damage to the drilling rig or equipment failure.

Including the application of riser, mud pump and return pipe choke manifold in circulating system. In the process of logging, the pump sends the drilling medium to the bit through the circulating system, and then sends the cuttings of the bit back to the ground for further refinement and treatment.

3. Fracturing, acidizing and cementing

In fracturing, acidizing and cementing operations, union pressure sensors are used for fracturing, acidizing and cementing operations for pressure monitoring and control.

Products

PPM union mud pressure measurement series

Features

High reliability: fully welded, integrated design, sensor diaphragm and union parts are processed into a sealed unit, reducing the chance of medium leakage to electronic components, and improving the overall reliability.

Robust and anti fatigue: fully welded, spherical sealed, stainless steel structure, special stainless steel anti-corrosion materials are used to isolate corrosive or abrasive drilling media from sensitive internal electronic equipment; The material maintains strength at higher temperatures to provide reliable performance under harsh conditions.

Explosion proof safety: obtain Ex ib IIC T4 Gb explosion-proof certification to reduce accidents

Easy to install and use: Horizontal or vertical direction can be quickly installed on site, with on-site calibration function, which is very convenient to use.

PPM Flush mount pressure transmitter series

Features

Robust and anti fatigue: the wetted part is made of stainless steel and fully welded. Avoid contact with any internal sealing elements. The shell is also made of stainless steel, which is durable and has a long service life.

Anti clogging and impact resistance: the process connection with flat embedded diaphragm and the all stainless steel integrated structure ensure that the impact of hard particles in the measured medium will not be counted as the sensor diaphragm. It is especially suitable for fluid pressure measurement of high temperature viscous slurry, strong field vibration and solid-liquid mixing.
