Provide "Tarim Solution" for efficient exploration of ultra-deep oilfields

On October 9, the cumulative production of oil and gas in Fuman Oilfield of PetroChina Tarim Oilfield exceeded the mark of 10 million tons, including 8.
67 million tons of crude oil and 1.
6 billion cubic meters of natural gas, equivalent to one-third of the annual oil and gas production equivalent of Tarim Oilfield, marking that China's ultra-deep oil and gas has entered a new stage
of large-scale development.

Located in the hinterland of the Taklamakan Desert, known as the "Sea of Death", Fuman Oilfield is the largest ultra-deep-sea phase fracture cave carbonate reservoir discovered in China, with oil and gas resources of 1 billion tons
.
The oil and gas buried in the ultra-deep depth of 7,500 meters to 10,000 meters is the largest oilfield with the best development efficiency built in China at a depth of 7,500 meters, and it is also the largest discovery made by Tarim Oilfield Company in oil exploration in the Tarim Basin in the past ten years, and ranked among the "Top Ten Super Projects of Central Enterprises"
in 2021.

Fuman Oilfield has the characteristics of ultra-deep, ultra-high temperature and ultra-high pressure, which are rare in the world, and it is extremely difficult to understand and identify the reservoir, especially in the ultra-deep underground precise control of the drill bit to drill oil and gas reservoirs, which is equivalent to "directional targeting" across an underground Mount Everest, which is no less difficult than "threading needles and leads"
100 meters away.
Traditional oil and gas geology theories and conventional drilling techniques are basically not applicable here, and the difficulty of exploration and development is "rare in the world and only in China"
.

In recent years, PetroChina Tarim Oilfield Co.
, Ltd.
has faced the problems of world-class exploration and development, innovatively established the "geological theory of ultra-deep marine carbonate fracture controlled reserves", conquered a series of technologies such as drilling and completion of ultra-deep and complex reservoirs, as well as efficient development technologies such as "four determinations + four selections" efficient well layout and "accurate quantification" production, and promoted the continuous "westward extension, eastward expansion, southward expansion and deep expansion" of the oil and gas bearing range of Fuman Oilfield, and maintained peak growth
of oil and gas reserves.

In the past four years, Fuman Oilfield has harvested 9 1,000-ton wells and 150 100-ton wells, built 16 oil and gas installations and stations, formed a surface system pattern of "two horizontal, two vertical and two centers", and crude oil production has risen
rapidly at an average annual growth rate of 500,000 tons for three consecutive years.
This year, the oil and gas output of Fuman Oilfield is expected to reach a new peak of 3.
4 million tons, providing a "Tarim plan"
for the efficient exploration and development of China's ultra-deep oilfield.

This year, among the 55 wells put into operation in the Fuman Oilfield, 52 test oil tests have obtained high production
of more than 100 tons per day.
According to the plan, by 2025, Fuman Oilfield will be built into an ultra-deep oilfield
with an annual output of 5 million tons of oil and gas equivalent.

The Tarim Basin is the largest onshore oil and gas bearing basin in China, and it is also the only oil and gas bearing basin in the world dominated by ultra-deep resources
.
Oil and gas buried in the basin with a depth of more than 6,000 meters accounts for more than 60% of China's total onshore ultra-deep oil and gas resources, accounting for about 19% of the world, and has great
potential for exploration and development.

In the past 10 years, PetroChina Tarim Oilfield Company has accelerated its advance into ultra-deep depths, drilled a rapid increase in the number of 8,000-meter ultra-deep wells, and penetrated 58 "underground Everest" of more than 8,000 meters, accounting for more than 80% of the country's ultra-deep wells, building China's largest ultra-deep oil and gas production base, and laying a leading position
in the world's ultra-deep oil and gas exploration and development.
