At 15:58 on November 12, with the opening of the last valve room No. 2 of Qinggao Line (Qing1 gas collection Station to Gaoshawo), natural gas in Ningqing block of Yumen Oilfield was smoothly injected into Qinggao Line pipeline, marking the era of "pipeline natural gas transmission" in Yumen Oilfield.

Previously, Yumen oil field natural gas production is small, can not be directly pipeline transport, can only rely on car transport. With the gradual increase of natural gas production in Ningqing block, natural gas is transferred by pipeline.

The production of the air intake work by the Yumen oil field Huanqing oil production leading group unified command, careful deployment. Before putting into operation, the leading group fully carried out special training on the process flow of the export pipeline, and inspected and debugged various types of equipment and valves for many times, dredged the card points and blocked points in each link, and ensured sufficient preparatory work. In the process of production, the leading group strictly implements the established plan, breaks down the task to each group, implements it to the specific responsible person, and fully guarantees the demand for production elements to achieve a successful production.

The expansion of natural gas sales channels makes the natural gas resources in Ningqing Block more effectively utilized, which is of great significance to optimize the energy structure of Ningxia region, improve the living standards of residents along the line, and promote the high-quality development of regional economy.
