Outline of China Petroleum's Overseas Pipeline Development

The first crude oil pipeline in the Sudan’s history was built from the earliest days abroad, and now the pipeline projects are spread across Asia and Africa. The Chinese oil people have spent only 13 years in the international pipeline market and have called CNPC's brand. These oil and gas pipelines that stretch over 10,000 kilometers are like a bond of friendship, linking China's oil and the country where the project is located.

Rapid growth from nothing

On August 30, 1999, in the Port of Sudan on the Red Sea coast, a tanker full of crude oil sailed to the Indian Ocean. Crude oil from the 1/2/4 oil field, the first large overseas oil field of China National Petroleum Corporation, officially entered the international market. This historic breakthrough was inseparable from the crude oil pipeline that had just been put into production three months ago. Long crude oil pipelines with a length of more than 1,500 kilometers will connect Hagrid with Port Sudan. The oil-rich Sudan finally realized the dream of crude oil exportation.

The successful operation of the 1/2/4 district crude oil pipeline has made the construction company China Oil one of its most famous. China Petroleum, which successfully entered the Sudanese market, has successively constructed high-quality, high-level crude oil pipelines in the 3/7 zone and heavy oil pipelines in the 6th zone. PetroChina not only helped the Sudan establish its own oil industry system, but also helped Sudan to initially build its own oil pipeline network.

In Kazakhstan, relying on upstream cooperation projects, CNPC successively constructed the Ken-A crude oil pipeline and the Sino-Kazakh crude oil pipeline. Among them, China-Kazakhstan crude oil pipeline is the first transnational crude oil pipeline in China. The successful commissioning of this pipeline laid a good foundation for the construction of the Central Asian Gas Pipeline across the four countries.

On December 14, 2009, with the opening of pipeline valves by the heads of state of China, Turkey, Ukraine, and Kazakhstan, the Central Asia Natural Gas Pipeline, known as the modern “Silk Road,” was formally put into operation. In October 2010, the Central Asia Gas Pipeline achieved double-pipe ventilation. This pipeline, together with the Sino-Russian crude oil pipeline and the Sino-Myanmar oil and gas pipeline, constitutes the onshore oil and gas import channel in China's four major oil and gas strategic channels.

As of August this year, CNPC's overseas operations are responsible for the construction and operation of overseas pipelines with an oil transmission capacity of more than 50 million tons/year and pipeline transmission capacity of more than 22 billion cubic meters/year. This figure is about to be refreshed by the Niger crude oil pipeline which was put into operation in October this year.

Technology helps the industry leader

The history of overseas pipeline business is also a history of innovation in pipeline science and technology. From the first crossing of the Nile River to the crossing of the Ili River, from the challenge of “three high” crude oils to the construction of long-distance, large-caliber, high-pressure natural gas pipelines, various overseas pipeline projects not only have to face more complex geological conditions than domestic ones, but also have to overcome One after another technical problem never seen before.

Sudan Pipeline 1/2/4 zone adopts the addition of pour point depressant conveying technology, which effectively reduces the number of heating stations along the line and saves investment. The project department is not satisfied. Based on the further study of stopping and restarting technology, the injection amount of the pour point depressant is gradually optimized, and the safe delivery of no pour point depressant is finally achieved. This alone will save nearly $8 million in annual pipeline operating costs.

Through pioneering the use of crude oil drag reducer technology in Sudan, the pipeline's oil transmission capacity has generally been increased by more than 15%. At present, the drag reducing agent technology still in the experimental stage in China is finally out of the laboratory and transformed into productivity. Elevated. This research achievement won the Group Corporation's first prize for technological innovation in 2002.

The Sino-Russian crude oil pipeline Heilongjiang crossing engineering pipeline anti-corrosion rate 100%, Jiangdi pipeline welding qualification rate 100%, pipeline life can ensure 50 years, no safety and environmental accidents during the construction period... One figure confirms the international quality of the crossing project. Level. During the construction of the crossing section, CNPC first innovatively adopted the pipeline back-dragging curing protection technology, which successfully achieved the objective of preventing damage to the anti-corrosion layer during the process of the back-dragging of Heilongjiang Pipeline.

Iron Man Spirit Exotic Flash

Regardless of where it is constructed, the efficiency of the Chinese oil workers will be amazed by the local people: 11 months, wearing deserts and swamps, across the Nile, built a pipeline running through Sudan's north and south; 28 months, built more than 1,800 km long single line The Central Asian Gas Pipeline. In the international community, similar projects of the same size, from the signing of natural gas purchase and sale agreements between governments to the completion of pipeline ventilation, will take at least six years.

Supporting the high efficiency of the oil people is an iron man spirit that “conditions must be met, and conditions must be met to create conditions”. Overseas working conditions are extremely difficult. There are nowhere to be found in the hundreds of kilometers of desert areas and deserted areas. In the Sudan, summer homework is endured by high temperatures in the neighborhood of 50 degrees Celsius. It is also constantly affected by infectious diseases such as malaria and malaria. In Kazakhstan, winter temperatures can drop below minus 40 degrees Celsius. The most unbearable is the long-term loneliness and loneliness. Many overseas oil men work in seven or eight years. Some of their wives can't wait at their labors. Some parents are unable to leave the bed to complete their filial piety.

The Chinese oil people, the "particularly able to fight, especially able to endure hardship, special dedication, and special victories," made the locals impressed. The Chinese oil people’s unreserved attitude towards technology and the training and assistance of local employees have also moved the local people. At the beginning of the construction of overseas pipeline projects, the host country of the project did not basically have its own pipeline construction talents and managerial talents. The overseas pipeline projects of CNPC enhanced the skills training of local employees through the “mastery belt” of the Chinese masters to improve the local employees. In terms of technology, a large number of oil and gas pipeline construction, operation management and technical talents have been cultivated for the host country of the project through the establishment of training bases, the holding of technical training courses, the selection of excellent employees each year to study and training in China and other countries. At present, the localization rate of CNPC’s overseas pipeline staff reaches more than 80%.

Today, standing at a new starting point in the 21st century and the next decade, CNPC's overseas pipeline business faces unprecedented opportunities for development and will also face an unprecedented complex international situation and turbulent social environment. In the face of new demands in the new era, overseas pipeline projects are still confident and are determined to create more success for the construction of “Overseas Daqing” and the comprehensive international energy company for China Petroleum Construction.
