CHONGQING, China, July 4, 2022 /PRNewswire/ -- China Petroleum
& Chemical Corporation (HKG: 0386, "Sinopec") has reported that
it has achieved a daily production capacity of 530,000 cubic meters
of shale gas on June 30 in its Xinye
Well-1 in Qijiang, Chongqing,
confirming the 100 billion cubic meters of shale gas reserves in
its Xinchang shale gas structure.
As of now, Sinopec has established the shale gas resource belt
of "Xinchang South – Dongxi – Dingshan – Lintanchang" (the "Belt")
in the southeastern Sichuan Basin,
with overall shale gas resource volume reaching 1.19305 trillion
cubic meters, the second trillion-level shale gas reserve of
Sinopec following its Fuling shale gas field that will contribute
to ensure China's energy
security.
The Xinye Well-1 has a depth of 5,756 meters, and the structure
belt has a large favorable area and resources of shale gas, making
it a key area for Sinopec's strategic exploration and production of
shale gas. The average well depth of the Belt is over 3,500 meters,
among which the deepest drilled Dingye Well-8's shale gas layer has
a depth of 4,614 meters.
The challenges of developing deep deposits include complex
ground stress and deep burial depth. Sinopec attaches great
importance to exploring deep shale gas and innovated theories and
technologies including fracturing for deep shale gas wells as well
as achieving domestic production of fracturing equipment, tools and
materials. Sinopec has realized 100 percent drilling ration of
high-quality shale.
In 2017, Sinopec established a deep shale gas R&D team to
pilot researches in Dongxi. After years of comprehensive research
and practices, Sinopec has built up the theoretical understanding
of deep shale gas geology and successfully unveiled the development
and maintaining mechanism of deep shale holes in deep-water
shelf-bathyal facies.
In addition, Sinopec also proposed deep shale gas layer sweet
spot prediction technology that has achieved high-precision
exploration, and developed deep shale gas fracturing engineering
technology that effectively addresses problems of burial depth and
plasticity, as well as high in-situ stress, to achieve
three-dimensional network fracturing technology that can ensure
precision cutting, pressurization, and proliferation, as well as
balanced expansion and filling.
Next, Sinopec will strengthen the precise evaluation of the
Xinchang gas field and elevate the overall evaluation and
deployment of the Belt shale gas resources in southeastern
Sichuan, thriving to achieve
continuous exploration breakthroughs.
