The Shuangyu 001-H6 well was safely drilled to a depth of 9010 meters, setting a record for the deepest natural gas horizontal well on land in China; The Tianwan 1 well test set a record for the highest formation pressure of 171.8 megapascals and the highest wellhead flow pressure of 123.4 megapascals in China; The record of the deepest vertical depth of a horizontal well in the Manshen 8 well set by the group company is 8331.9 meters... A series of new records demonstrate China Petroleum's confidence and confidence in ensuring national energy security.

  The oilfield technology service business takes ensuring national energy security as its responsibility, conscientiously implements the decision-making and deployment of the group company's party group, coordinates the implementation of the "innovation, market, low cost, and integration" strategy, vigorously practices the "safety, compliance, efficiency, and effectiveness" policy, effectively supports the group company's oil and gas main business of "increasing storage, increasing production, and reducing costs", continuously creates the "domestic best", refreshes more than 200 various indicators, and helps the group company achieve high-quality development in exploration and development.

Focus on efficient exploration and support new breakthroughs in oil and gas exploration. CPC Technical Service is based on the positioning of "one body, two sides", firmly establishing the concept of "achieving the first party can achieve oneself", effectively strengthening the coordination between the two levels, closely communicating and exchanging between the first and second parties, establishing a monthly negotiation mechanism, and effectively implementing a series of cooperation consensus. Timely meet the drilling needs of key areas such as Qinghai, Liaohe, Bayan in North China, and Southwest China, and assist in the discovery of 209 new wells and over 100 wells with 100 tons and million cubic meters in domestic oil and gas exploration. Building three technological swords, upgrading and shifting gears to speed up and improve efficiency, with a 10.5% increase in speed for deep wells over 5000 meters, a 13.8% increase in speed for factory fracturing, and a 14.76%, 16.1%, and 15.9% year-on-year increase in operational efficiency for single teams in Changqing, Sichuan Chongqing, and Tarim, respectively. Fully guarantee the increase in oil and gas reserves and production of the group company, and support important discoveries such as Tianwan 1 well in China; And a large number of overseas exploration achievements have been made in Doxao, Chad, Bilma, Niger, and the Caspian Sea in Kazakhstan. The S88 project in Saudi Arabia collected 833600 seismic data in a single month, breaking the historical record of Saudi Aramco.

Persist in building enterprises through technology and achieve new results through technological innovation. CPC Technical Service has established an Engineering Technology Professional Committee and four sub professional technical committees, and introduced systems such as the "Science and Technology Project Management Measures", with the science and technology management system becoming increasingly perfect. Scientific and technological breakthroughs continued, key projects such as high-temperature logging chips made key breakthroughs, and the key laboratory of marine natural gas hydrate engineering was identified as the sub center of the National Engineering Research Center for natural gas hydrate exploration and development, and subordinate enterprises such as Dongfang Geophysical Prospecting and Marine Engineering were selected as the second batch of "science and technology innovation demonstration enterprises" of the SASAC. We have increased investment in scientific research, solidly promoted the transformation of achievements, successfully developed AI high-precision earthquake initial arrival picking software, and promoted the supporting technology of "engineering operation machine and pipe air drill" on a large scale. The CPlog complete set of equipment has been applied overseas for the first time, providing strong support for safety production, speed improvement, and efficiency enhancement.

Promote the improvement of quality and efficiency, and create new achievements in value creation. CPC Technical Service implements the "Four Refinements" management requirements, implements the "Eight Efficiency Enhancement Projects", and achieves "Two Increases, One Control, and Three Improvements" through "Two Profits and Four Rates". Expanding domestic and international markets, we have obtained multiple contracts worth over 100 million US dollars, including drilling and repair contracts in Mexico and Kuwait, and cultivated 11 large-scale markets with annual contract amounts exceeding 100 million US dollars. Significant results have been achieved in the management of losses, with 4 subsidiary enterprises at the entire level reducing losses and 7 legal entities reducing losses. Develop a plan for new energy and new business, implement a carbon peak plan, accelerate energy substitution, use electric instead of oil drilling rigs, promote electric fracturing on a large scale, and replace a total of 420000 tons of diesel, saving 1.1 billion yuan in costs.
