Heavy! Sinopec shale gas exploration major breakthrough! Discover two more 100 billion gas fields!

At the beginning of the new year, China's domestic oil and gas exploration has continuously made major breakthroughs
.
Sinopec, which is known for shale gas, is even more energetic to announce the new discovery
of two major shale gas fields in one breath.
At the same time, Sinopec's shale gas company in Sichuan is even more boots, with a registered capital of more than 3 billion yuan alone!

Jianghan Oilfield discovered 100 billion square meters of shale gas resources in Enshi

On January 18, Sinopec Jianghan Oilfield deployed in the red page 2HF well of shale gas pre-exploration well in Lichuan Hongxing area, Enshi Prefecture, Hubei Province, and has been tested for production for 20 consecutive days, and Nissan shale gas remains stable
.
This is another stable shale gas exploration well deployed in the area, further confirming the exploration potential
of the area.
At present, Jianghan Oilfield has submitted the first batch of shale gas forecast reserves of 105.
103 billion cubic meters in the
region.

It is understood that there are many problems in the Lichuan Hongxing area, such as large shale burial depth and complex ground stress, with high technical requirements and difficult exploration and development
.
In December 2020, Jianghan Oilfield overcame technical difficulties, and the subordinate Red Page 1HF well produced 89,000 cubic meters of gas per day, filling the gap
in China's Permian shale gas exploration and development.
At present, the well has accumulated more than 20 million cubic meters of gas, which is the highest gas production shale gas well
in Hubei Province.
Following the breakthrough of the Red Page 1HF well, Jianghan Oilfield has successively deployed shale gas pre-exploration wells
such as Red Page 2HF and Red Page 3HF.
At present, the shale gas production of the Red Page 2HF well is stable, and the effect is better than that of the Red Page 1HF well, which further demonstrates the good exploration and development prospects of
the area.

China is rich in shale gas resources, has huge resource potential and prospect for exploration and development, and achieving its scale benefit development is of great strategic significance
to ensuring national energy security。 In recent years, Sinopec has continued to increase its efforts in shale gas exploration and
development.
In 2017, Fuling Shale Gas Field, the first large-scale shale gas field in China with 10 billion square meters, has accumulated more than 40 billion cubic meters of gas so far, with a cumulative proven reserve of nearly 900 billion cubic meters, accounting for 34%
of the country's proven shale gas reserves.
In 2018, it was discovered that China's first deep shale gas field, Weirong Shale Gas Field, was discovered, and an annual production capacity
of 1 billion cubic meters was built in 2020.
In 2021, the Dongshashen 2 well, a key ultra-deep exploration well deployed in Chongqing, will test 412,000 square meters of shale gas per day in the gas layer with a buried depth of 4,300 meters, marking a new major progress
in the field of deep shale gas exploration with a burial depth of more than 4,000 meters.

Shale gas refers to unconventional natural gas deposited in organic mudstone-rich shale and its interlayer, in an adsorption or free state, the composition of methane, is a clean, efficient energy resources and chemical raw materials, mainly used for residential gas, city heating, power generation, automobile fuel and chemical production, etc.
, widely
used.

In addition, Sinopec has also made a number of breakthroughs
in the field of shale oil exploration and development.
In November 2021, Sinopec Shengli Oilfield made significant progress in shale oil exploration and development in the eastern probe area, reporting the first batch of predicted shale oil geological reserves of 458 million tons, and preliminarily estimating shale oil resources in the region to reach more than
4 billion tons.
In December 2021, shale oil exploration made another strategic breakthrough, and implemented a favorable area of 420 square kilometers and 350 million tons
of shale oil resources in the Qintong Sag area of the Northern Jiangsu Basin.

A major breakthrough has been made in shale gas exploration in Zhongyuan Oilfield

On January 12, the Pulu Page 1 well, the first special shale gas exploration well in Zhongyuan Oilfield, obtained an industrial gas flow of 104,000 cubic meters per day in the gas test operation, and implemented 650 billion cubic meters
of shale gas favorable area resources in the Puguang East Slope Jurassic Thousand Buddha Cliff Formation.
This marks that Zhongyuan Oilfield has achieved a major breakthrough in shale gas exploration in the northeast Sichuan Industrial Zone, and has opened up a broad field of resource succession for medium- and long-term development!

In fact, as early as 2015, Zhongyuan Oilfield launched a stratified system evaluation of shale gas resources, but what really ignited the fire of hope in the hearts of researchers was the exploration breakthrough
of Pulu 3 Well.
The breakthrough layer of the well and the main attack layer of continental shale gas selected by them are located in the same section of the Jurassic Thousand Buddha Cliff Formation, which is only more than 30 meters
apart from the vertical direction.

What is even more pleasing to the researchers is that they found that the factors affecting the high yield of Pulu 3 well are more complex, while Qianyi Section develops a large area, continuous, low-speed black mudstone, and the accumulation mode is self-generated and self-storage, which is equivalent to directly going to the "angry" source rock to find gas
.

On April 10, 2021, Zhongyuan Oilfield completed the drilling of the guide eye section of the Pulu Page 1 well, and explained the fractured gas aquifer 33 m/7 layer in the main target layer
.

The core immersion test of Pulu Page 1 well, a large number of beaded bubbles continuously overflowed, which confirmed good gas content
.

Considering the pioneering significance of Pulu Page 1 well, and in order to obtain first-hand information to promote shale gas exploration from point to surface, Zhongyuan Oilfield decided to carry out systematic coring of "wearing boots and hats" for Qianduan, and carried out 2388 small indoor and outdoor analysis and testing for the cores obtained, and finally found the 10-meter shale gas "dessert" layer with the largest shale thickness, the most developed shale theory, the deepest color, the best continuity and gas content, and determined the favorable target window
for horizontal section drilling.

The exploration breakthrough of Pulu Page 1 well not only allows Zhongyuan Oilfield to further tighten the lifeblood of survival, but also opens up the research horizons
of domestic shale gas exploration workers from the perspective of continental sedimentation.

In addition, in recent years, Zhongyuan Oilfield has also spread the exploration scene of tight sandstone gas through the drilling of Pulu 3 well, Pulu 4 well and other wells, so that the Jurassic Qianyi section has formed a "box-type" accumulation pattern of "upper box tight sandstone gas and lower box shale gas", with a total resource of 773.
7 billion cubic meters
.

Following the breakthrough in the exploration of the Pulu Page 1 well, the Zhongyuan Crude Oil Field has successively deployed the Pulu Page 2 well, the Pulu Page 3 well, the Pulu 7 well, the Pulu 8 well and other wells, and strives to make the continental exploration in the northeast Sichuan industrial area "shine", and by the end of the "14th Five-Year Plan", the proven natural gas geological reserves in the field of continental shale gas and tight sandstone gas are 115 billion cubic meters, contributing to the "rice bowl" of Duanqiang energy

.
The average burial depth of the gas field is 3750 meters, which belongs to the deep shale gas field, and a series of scientific and technological problems have been overcome in the development process, and the bottleneck of the deep shale gas field with a burial depth of 3500 meters to 4000 meters has been broken, and the scale and efficient development
have been realized.
