On July 25th, the construction project of a 10 billion cubic meter production capacity in the Bozi Dabei ultra deep gas field of Tarim Oilfield began, marking the comprehensive development and construction of China's largest ultra deep condensate gas field. The annual production of oil and gas in the Bozi Dabei Gas Field will reach 10 billion cubic meters and 1.02 million tons respectively by the end of the 14th Five Year Plan, which is equivalent to adding a million ton high efficiency oil field to the country every year. It is of great significance for ensuring national energy security and improving natural gas supply capacity.
Bozi Dabei Gas Area is located at the southern foot of Tianshan Mountains in Xinjiang and the northern edge of Tarim Basin. It is another trillion cubic meter atmospheric area discovered in the ultra deep layer of Tarim Oilfield in recent years after the discovery of the Kela Keshen trillion cubic meter atmospheric area, and it is also one of the main gas production areas in the "14th Five Year Plan" for the increase of clean energy reserves of natural gas in China. In 2021, the Bozi Dabei Gas Field produced 5.2 billion cubic meters of natural gas, 380000 tons of condensate, and 4.54 million tons of oil and gas equivalent.
It is understood that during the 14th Five Year Plan period, Tarim Oilfield will deploy more than 60 new wells in the Bozi Dabei gas field, promoting rapid production of the gas field at an annual growth rate of one million tons. A new ground skeleton project will be built, mainly consisting of three major projects: natural gas processing plants, condensate stabilization devices, and oil and gas export pipelines. The daily natural gas processing capacity will be increased from 17.5 million cubic meters in the past to 37.5 million cubic meters, fully releasing oil and gas production capacity.
Unlike the medium to shallow atmospheric oil and gas reservoirs of 1500 to 4000 meters in foreign countries, the vast majority of oil and gas in the Tarim Oilfield are located in ultra deep layers seven to eight kilometers underground. The difficulty of exploration and development is rare in the world and unique to China. Among the 13 indicators for measuring drilling and completion difficulty in the industry, the Tarim Oilfield ranks first in the world in 7 of them.
In recent years, the Tarim Oilfield has successfully developed 19 large and medium-sized gas fields, including the Bozi 9 gas reservoir, which has the highest formation pressure in China, and has become one of the three major gas fields in China. The cumulative gas supply downstream of the West-East Gas Pipeline has exceeded 308.7 billion cubic meters, and the gas supply to the southern Xinjiang region has exceeded 48.3 billion cubic meters, benefiting about 400 million residents in 15 provinces, cities, and more than 120 large and medium-sized cities such as Beijing and Shanghai. It covers 42 counties, cities, and agricultural and pastoral farms in the five southern Xinjiang regions, greatly promoting the optimization and adjustment of energy and industrial structure in eastern China, driving the economic and social development of Xinjiang, and creating huge social, economic, and ecological environmental benefits.
It is reported that the condensate oil and gas developed in the Bozi Dabei Gas Field is rich in rare hydrocarbon components such as aromatic hydrocarbons and light hydrocarbons. It is a high-end petrochemical raw material urgently needed by the country, which can further increase downstream ethane and liquid hydrocarbon production, drive the upgrading of the petrochemical industry chain, intensive utilization of advantageous resources, and deep transformation. Currently, the Tarim Oilfield has produced over 150 million tons of condensate oil and gas, effectively supporting the industrial scale application of condensate oil and gas.
