In the south of China’s exotic Xinjiang province
Between the Tianshan and Kunlun mountains
There is a desert area of nearly 400,000 square kilometers
Tarim basin
Tarim basin is a large closed intermountain basin
The widest point in the north and south is about 520 kilometers, and the longest point in the east and west is about 1400 kilometers
The terrain is high in the west and low in the east, with an elevation of 800-1300 meters
Because the Tarim basin underwent a long period of plate compression and movement hundreds of millions of years ago
Large deposits of ancient animals gradually formed here
It also left a valuable legacy for China
The basin seemed inhospitable
But there are tens of billions of tons of resources hidden underground
Statistics: China in the Tarim basin
Proven oil and gas reserves amount to 16 billion tons
Therefore, it is called the successor of China petroleum strategy in the 21st century by geologists
Oil and gas exploration and development in the Tarim basin began as early as the 1950s
Tarim oil field was formally completed in 1989
And gradually become China’s western energy economic center
In addition, it is one of the main sources of China’s west-east gas transmission project
Recently, the Tarim basin again came the good news
Another large oil and gas field in China has been successfully explored
Up to 200 million tons of oil are known to be in storage.
Tarim oilfield, April 8
Full exploration well 1 is produced by 10 mm nozzle test
It produces 624 cubic meters of crude oil and 371,000 cubic meters of natural gas per day
It marked a breakthrough in the exploration of oil and gas in the deep abdomen of the basin
Open up a new oil and gas strategy replacement area
Manshen 1 well is located in Shaya county, Xinjiang province
It is a key exploration well of Tarim oil field deployed in the exploration new area on the south bank of Tahe river
Located in the north of the tower, a tower between the two ancient uplifts between the saddle
The exploration and development layer is an ancient Marine carbonate rock formation dating back 440 million years
The burial depth is more than 8000 meters
This formation mainly consists of fractures and caves
It faces a series of world problems in exploration and development
In the last decade or so
The exploration workers in Tarim oilfield continue to crack the carbonate rocks
The team finally broke through the technical bottleneck of drilling in the ultra-deep carbonate rock formation
How to obtain the detailed structure of eight kilometers underground rock seam
Tarim oilfield’s technicians use the world’s leading 3d seismic technology
Obtain the structure diagram by taking CT images
And the drill can follow a predetermined trajectory
To avoid damaging the geological structure
The company USES geosteering technology to break through barriers
Finally, a complete super-deep carbonate drilling technology is constructed
It provides important theoretical and technical support for the development of Tarim oil and gas field
Yang Xuewen, general manager of China petroleum Tarim oilfield company
A major breakthrough in the deep 1 well
It is further confirmed that there is oil in the north Tarim basin
An additional 3,520 square kilometers of favorable exploration area will be created
For Tarim oilfield to accelerate the north-tower
A solid foundation has been laid for the construction of a ten-million-ton oil and gas zone
Tarim Basin is the largest petroliferous basin in China
The country will produce 28.51 million tons of oil and gas in 2019
It is planned to build a large modern oil and gas field of 30 million tons by the end of 2020
In addition to oil, as the transmission source of west-east gas
So far the Tarim basin gas field has been to the country
More than 200 billion cubic meters of gas were delivered
The entire Tarim basin produces a year’s worth of natural gas
That’s one-sixth of the country’s total production
This gas also bears the burden of east China
North China has 120 large and medium-sized cities with a population of more than 400 million
The gas supply task of more than 3000 enterprises
Except for oil and gas fields
The arid Tarim basin is also rich in water resources
The moist ocean air is blocked by the mountains surrounding the basin
Precipitation in the Tarim basin is very low
It averages less than 10cm a year and is also due to shallow water levels
Nor will the muddy Tarim river provide much water
Surprisingly, Chinese scientists have found huge amounts of water here
It holds ten times more water than the five great lakes of North America combined
Scientists call this huge reservoir an underground ocean
The report is in the journal geophysical research letters
Why is there so much water in arid deserts?
According to the analysis report: Tarim basin moisture mainly from the westerly airflow
Atmospheric air flows from central Asia across the Tenan mountain valley
And through a series of lakes
Annual precipitation in the surrounding mountains ranges from 200 to 400 millimeters
The rain eventually converges into rivers and reaches the basin
The Tarim basin is a valuable treasure of China
We don’t know what other surprises it will bring us
It is also China’s oldest inland cotton-producing region
The illumination condition is good, the heat is rich, the temperature difference between day and night is big
It is beneficial to the accumulation of nutrients and harmful to the propagation of pests
You don’t even have to use pesticides
It is also a famous melon and fruit producing area in China
Rich korla fragrant pear, kuqa apricot, artoshi figs
Ye city pomegranate, hetian red grapes and so on
It’s a foodie’s paradise
