Water resources efficiently use Xinjiang Oilfield Heavy Oil Company to save 6 West Lakes in 9 years

Tianshan News (Reporter Yu Jiangyan Correspondent Zhang Youwen) from 2013 to 2021, 9 years, China Petroleum Xinjiang Oilfield Branch Heavy Oil Development Company (hereinafter referred to as Xinjiang Oilfield Heavy Oil Company) saves 94.16 million cubic meters of Xinshui, saving The amount is about 565 million yuan. Based on the water storage volume of about 14.29 million cubic meters of West Lake, Xinjiang Oilfield Heavy Oil Company saved more than 6 West Lake water in 9 years.

On July 1, the reporter learned from Xinjiang Oilfield Heavy Oil Company that the company's water consumption "big households" is a boiler -boiler. When using steam mining technology to use thick oil, you must first use the boiler to heat the water into high -temperature steam with more than 300 degrees Celsius, and then transport it to the oil well through the pipe network to inject the stratum. Mining. Before 2013, the boiler room used new water to heated to steam. After 2013, purified water was used to heat into steam. "The thick oil collected by the steam mining technology contains both oil and water. After the ground is collected, it must be separated from oil water. After the sewage treatment station is treated, it softes, and then enter the boiler room. Heating steam can be used in a cycle. "Zhu Hua, deputy head of the production technology department of Xinjiang Oilfield Heavy Oil Company, explained.

In addition to the reuse of sewage in thick oil mining, the company also uses sewage treatment of storage tanks and well repair operations.

In order to achieve the efficient use of water resources, in recent years, Xinjiang Oilfield Heavy Oil Company has continued to improve equipment and process processes, and has successively implemented projects such as high -salt buffer system transformation and screw pump technology transformation. For the sewage treatment joint station that transports the sewage of purifying sewage for the vaporic system, technicians can ensure that the water -saving process transformation is optimized to ensure 100%of the high saline.

It is worth mentioning that in recent years, the sewage treatment station of Xinjiang Oilfield Heavy Oil Company has also implemented water waste heat use of heating energy saving transformation projects, using a new type of flow tract sewage heat exchanger to extract heat from high temperature sewage from 70 degrees Celsius, and heat insulation with insulation. Circular water is used for heat exchange. In the end, these extracted waste heat is used for winter heating in the station area. This project alone achieves about 10,500 tons of steam in the year, saves 683,000 cubic meters of natural gas, saves 13,000 cubic meters of new water, and can create 1.01 million yuan in economic benefits.

During the "Thirteenth Five -Year Plan" period, Xinjiang Oilfield Heavy Oil Company exceeded the energy -saving indicator of energy conservation, and changed from "big energy consumption" to "big energy -saving households". Through management innovation and technological update, Xinjiang Oilfield Heavy Oil Company has gradually formed a comprehensive energy -saving system for thick oil development energy consumption of "collection, injection, losing, dirty, and setting".
