On the one5th, China Petroleum released a message,The largest ultra deep condensate gas field in China, Bozi Dabei Gas Field in Tarim Basin, has been fully completed and put into operation, marking a new stage of large-scale development in the new trillion cubic meter atmospheric area of the Tarim Basin, adding new guarantees for the safe and stable gas supply of the West East Gas Pipeline.

Bozi Dabei Gas Field is located at the southern foot of the Tianshan Mountains in Xinjiang, and is a national key project. The gas field covers an area of over one3000 square kilometers and is located in Baicheng and Wensu counties. The comprehensive completion of surface engineering construction in the gas field has effectively ensured the stable supply of natural gas and emergency peak shaving.

Wang Chaohui, Senior Expert of the Oil and Gas Field Capacity Construction Division of PetroChina Tarim Oilfield

We have built three major ground skeleton projects, including a natural gas processing plant, a condensate stabilization device, and an oil and gas export pipeline. The maximum annual gas transmission capacity has increased from 5 billion cubic meters to onetwo billion cubic meters, enabling the interconnection of the South Tianshan ultra deep gas field group.

The gas field belongs to a new trillion cubic meters atmospheric area discovered in the ultra deep layers of Tarim Oilfield in recent years. Tarim Oilfield has drilled more than one00 deep wells here, and is expected to produce over 9 billion cubic meters of condensate gas and over 600000 tons of condensate oil this year.

Li Zhiming, the person in charge of the Boda Oil and Gas Production Management Zone of PetroChina Tarim Oilfield:

This project has undergone over 450 days of intense construction, and the daily gas supply capacity will increase from two5 million cubic meters before production to 3one million cubic meters. If a family of three uses one.5 cubic meters of daily gas, we can provide daily gas for more than two0 million households every day.

Condensate, also known as natural gasoline, is rich in rare hydrocarbon components such as aromatics and light hydrocarbons, and is a high-end petrochemical raw material urgently needed by the country. Condensate gas is natural gas containing condensate oil. The global condensate oil and gas resources are mainly distributed in Central Asia, Russia, and North America, with burial depths ranging from one500 to 4000 meters, belonging to medium to shallow atmospheric gas reservoirs. China is mostly a deep condensate gas reservoir, with more than 80% of its proven reserves concentrated in the Tarim Basin, which is stored in rocks seven or eight kilometers underground.

Zhou Jianping, Chief Engineer of Boda Oil and Gas Production Management Zone, Tarim Oilfield, China:

In recent years, we have overcome a series of "bottleneck" problems such as ultra deep drilling and completion, as well as large-scale development in the Bozi Dabei gas field. Before and after the renovation, the open flow rate of the gas well has increased by five times, achieving a leap in the exploration and development technology of condensate gas fields from deep to ultra deep, from high pressure to ultra-high pressure, and from high-quality reservoirs to complex reservoirs.

Development of condensate oil and gas in Tarim Oilfield

Fill multiple technical gaps

Most of the condensate oil and gas in the Tarim Basin are stored in rocks seven or eight kilometers underground, which is very difficult to exploit. Technicians have increased scientific and technological research, overcome a series of problems in the development of ultra deep and ultra high pressure condensate gas fields, and provided support for industrial scale application.
