- Producing 171 tons of shale oil daily, the Fanye-1 Well sets
China's highest production record
for a single shale oil well.
- 1 million tons of shale oil production capacity expected to
be built in the next five years.
- Initial estimates of shale oil resources in the region
amount to 4 billion tons.
BEIJING, Nov. 3, 2021 /PRNewswire/ -- The four designated
shale oil prospecting wells in the East Exploratory Area of Shengli
Oilfield of China Petroleum & Chemical Corporation (HKG: 0386,
"Sinopec") reported high oil flow on November 3, among which the Fanye-1 Well achieved
peak daily oil production of 171 tons, setting the highest shale
oil production record of a single well in China.
A strategic breakthrough in shale oil exploration in Shengli
Oilfield, the record-breaking achievement has exhibited the area's
bright prospects for shale oil exploration and development.
Shengli Oilfield has reported the first batch of shale oil
geological reserves to reach 458 million tons by current
predictions. Preliminary estimates have shown that shale
oil resources in the region amount to more than 4 billion tons
marking a practically new territory for increasing reserves and
production in eastern China.
Shale oil is the petroleum resource stored in the
micro/nano-sized pores of shale layers. The shale oil developed in
Shengli Oilfield is at a depth of over 3,000 meters at a
temperature reaching 170 degrees Celsius in a storage space that's
finer than a hair. The low degree of geological evolution, high
density, poor fluidity and difficult development scenario have
challenged techniques including drilling and fracturing.
To solve problems in shale oil exploration and development,
Shengli Oilfield has innovated three major
technologies to break through the bottlenecks. It has
carried out more than 40 types of shale oil research at various
levels, including the National Basic Research Program
of China (973 Program) and major special projects,
in the past decade such as:
- Establishing a shale oil accumulation and enrichment model in
continental faulted basins to develop shale oil optimization
evaluation technology that uncovers the "hiding places" of shale
oil;
- Developing high-quality fast drilling technology with
synthetic-based drilling fluids to enable efficient drilling of
horizontal wells of over 2,000 meters at depths below 3,300
meters;
- Accomplishing multi-scale combined network fracturing
technology that allows shale oil to discharge on hundreds of
artificially manufactured millimeter-level "highways".
At the moment, Shengli Oilfield is fully equipped for the
comprehensive exploration and development of shale oil. The company
is working on technologies for longer horizontal sections,
multi-layer and three-dimensional development, innovatively
applying the "well factory" model to speed up the establishment of
a national-level shale oil development pioneering zone in the
Jiyang continental fault basin.
"The next step for Sinopec Shengli Oilfield is to continue
conducting in-depth research and improving engineering capabilities
to support the increase of large-scale shale oil reserve and
production. It's expected shale oil production capacity reaching 1
million tons will be built in the next five years, consolidating
production yield and energy security resilience in China," noted Kong Fanqun, Assistant to the
President of Sinopec and Executive Director of Sinopec Shengli
Oilfield.
Sinopec has also reported major breakthroughs in the field of
shale gas exploration, including the establishment of China's first large-scale shale gas field, the
Fuling shale gas field; the discovery of China's first deep shale gas field, the
Weirong shale gas field, the first phase of which has built a
production capacity of 1 billion cubic meters in 2020; as well as
the Dongye Deep 2 key shale gas prospecting well in
Sichuan Basin that has been tested
to produce 412,000 cubic meters of high-quality shale gas daily and
marked significant achievement in the exploration of ultradeep
shale gas at a depth of over 4,000 meters.
