In 2009, the Group carried out
petroleum engineering iron team building campaign with
the aim of constantly improving the construction
capacity and technological level through intensified
organizational management, technical skill training and
market expansion. This strongly supported the E & P
business of the Group and raised its competitiveness in
the market.
Construction
The Group set 36 new records in petroleum
engineering, among which 28 ranked among the 14th batch
of Chinese enterprise new record. It completed 55,683 km
of 2D seismic survey, up by 22.2% year on year; 10,501
square km of 3D seismic survey, up by 47.1% year on
year. It drilled 4130 wells with footage of 10.2434
million meters. The revenue arising from oilfield
surface engineering construction was 16.52 billion RMB,
up by 32.15% year on year. The revenue from petroleum
mechanical manufacturing was 5.102 billion RMB.
Engineering Technology
The Group sought to make technological breakthrough
and pilot experiment in five key areas including
drilling and completion technique of horizontal well and
special structured well, petroleum engineering equipment
R&D and manufacturing technology, reservoir improvement
technology, high precision 3D seismic exploration
technology and logging technology in complex reservoir
and to push the commercialization of mature technology,
which facilitates the effective development of key
technologies. High precision 3D seismic exploration
technology provides sound foundation for precisely
defining small-fault-blocks and small traps and
describing complex reservoirs.
By 2009, Shengli, Zhongyuan, Jiangsu, Jianghan and
Henan oilfields have completed high precision seismic in
oil rich sag covering an area of 10,276 square km,
accounting for 11% of the total 3D seismic workload. The
success rate of complex oil reservoir exploration has
been increased by a large margin.
Quite a few new drilling technologies were
commercialized; major breakthroughs were vertical
drilling technology, gas drilling technology, solid
expandable tubular technology, etc.; drilling speeds in
key regions like Tahe and Sichuan were raised by a large
margin. Complex reservoir improvement technology was
improved further: Sichuan new 11 well reservoir was
reconstructed successfully with fracturing which ensures
the fulfillment of finding hundred billion cubic meters
of new proven reserve.
The Group established Research Institute of Petroleum
Engineering and Research Institute of Geophysical
Exploration, thus basically forming a complete system of
petroleum engineering technology R&D and
commercialization.
Drilling speed and efficiency increase
The Group carried out research campaign aiming at
increasing the drilling speed and efficiency according
to the prominent problems and technological demands from
three key exploration and development regions including
Northwest, west Sichuan and Yuanba areas. The research
team indentified the research objectives, technological
measures, and progressive schedule after deeply studying
the technological difficulties, followed by intensified
production and research efforts focusing on safe,
managed and technology-based speed increasing. The
drilling speed and efficiency was increased apparently,
making great contribution to the fulfillment of the
reserve and production targets in key regions.
The Group completed drilling 10 deep wells in western
Sichuan area and deep wells’ production time efficiency
reached 92.91%, up 25.89% year on year. Drilling speed
in western Sichuan area was constantly increased,
setting regional records in terms of 10 indicators
including highest monthly drilling speed, shortest
drilling cycle and highest time efficiency. Yuba area
hit the highest record of monthly footage, with its
average monthly mechanical drilling speed reaching 3.37
m/h, the highest value for the whole year. North West
area hit regional records in terms of 24 indicators and
completed 10 excellent projects, which enable it to
reach the daily production level by 4 months ahead of
time, and exceed the targets of reserve and production.
External market
Facing the severe situation, the petroleum
engineering team sought to turn pressure into motivation
and find opportunities amidst adversity. They equipped
themselves with advanced facilities and most capable
team members, put great efforts in optimizing production
activities and expanding external market, so that they
increased their market competitiveness and scored great
achievements in external market. Revenue from external
market accounted for 23.73% of the total revenue of
petroleum engineering.
