Saisi x Changqing Oilfield | Saisi assists in the construction of the communication transmission network of the Changqing Oilfield

Saisi supplied a set of high-precision network synchronization equipment to Changqing Oilfield, ensuring the frequency stability and synchronization of the communication transmission network of China's largest oil and gas field.

China Petroleum Changqing Oilfield Branch, established in 1970, is headquartered in Xi'an, Shaanxi Province, and is the largest oil and gas field in China. Its exploration areas are mainly located in the Shaanxi-Gansu-Ningxia Basin, covering a total exploration area of approximately 370,000 square kilometers. It has discovered 22 oil and gas fields, including 19 oil fields, with a cumulative proven geological reserve of 541.888 million tons.

The petroleum communication network is the second largest dedicated communication network in China, consisting of a backbone transmission network and regional local networks, which supports core business demands such as petroleum exploration and production, chemical and sales, refining and sales, natural gas and pipelines. With the continuous development of the petroleum industry, the scale of the petroleum backbone transmission network is growing larger, the number of services it carries is increasing, and the network structure is becoming more complex. Ensuring the frequency stability and synchronization of the transmission network is of great significance.

Saisi's SM2000 high-precision network synchronization device, developed for diverse communication transmission networks, utilizes digital phase-locked loop technology and FPGA-based autonomous timing algorithms. Supporting IEEE15888 standards, it delivers telecom-grade time-frequency reference signals with exceptional accuracy and reliability. Certified by Tel Labs and granted Class 1/2 node clock equipment access by China's Ministry of Industry and Information Technology (MIIT), this product provides reference clock sources compliant with ITU-T G.811 and G.812 standards.

The SM2000 is a time-frequency integrated synchronization device that provides not only traditional 2Mbit/2MHz frequency synchronization signals but also time outputs including PPS+TOD, NTP, and PTP. Currently, this product has been widely adopted in communication synchronization network scenarios such as mobile operators, power systems, rail transit, and petrochemical industries.

Going forward, Saisi will continue to focus on the integration of production and research, deepen its expertise in time-frequency technology, drive industrial transformation, and strive to become a global pioneer in this field.
