Science and technology weapon help to reach the "underground Everest"

On September 3, 2022, Pisces 001-H6, located in the Sichuan Basin, officially entered the oil test stage. The various work at the scene was organized. Everyone was full of confidence in the production capacity of this well.

On June 23 this year, the well finished in the 9010 meter well, and became a horizontal well in the first mouth of Petroleum in the history of PetroChina, which is 161.14 meters higher than the highest level of Musou Langma Peak (8848.86 meters) on the earth (8848.86 meters). In one fell swoop, setting the deepest record of my country's land, becoming another milestone in the history of drilling technology!

The Sichuan Basin ultra -deep well construction is a recognized world -class problem. Pisces 001-H6 is the first 9000-meter-level ultra-deep sulfur-containing high-temperature high-pressure natural gas level well as the first 9000-meter-level high-temperature high-temperature high-pressure natural gas level well. The deep "climbing", Chuanqing Drilling Drilling Institute Drilling Well Design, Geological -oriented, Fine Pressure Drilling wells, EISS Digital Platform, and other international first -class special technologies have successively "brightened swords", and "complex oil and gas The momentum and strength of the tiers.

"The drilling and well -ended design of this well is challenging and glory!" At the beginning of the drilling well, the drilling well design team revolved around the well -stratum strata, complicated pressure systems, long -eye sections, deep strata, and deep strata. The technical difficulties such as poor drilling work hard work, comparing and preferred from various aspects such as drilling speed, timeliness, and economy. The preparation of the Pisces 001-H6 well drilling project plan has laid a good start for the entire drilling.

In the process of drilling the well, Chuanqing drilling creative application information technology, using the powerful data transfer support function of the EISS system, integrating on -site multi -professional data resources such as drilling, metering wells, and optimization of real -time analysis, complex warning and engineering parameters. Realized complex predictions and fast drilling.

The underground "navigation" uses the "CQ-IGS horizontal integration geological-oriented technology" independently developed to provide real-time geological orientation services for the horizontal segment, accurately judge the reservoir, and control the quality of the standard quality of 100%, accurately control the standard rate, accurately control The real -time drilling trajectory is stable and efficient in the reservoir of nearly 8,000 meters underground.

At the same time, by adopting fine -controlled pressure drilling wells, the stratum pressure was released 19 times, and the pressure coefficient of the well was successfully reduced from 2.21 to 1.98, and the safety operation window was re -established to effectively prevent and control the complicated leakage. Among the wells of the well -tube of the well, the pressure accuracy of the well is firmly locked at 0.1MPa to ensure the success of the well -solid well and provide a solid foundation for ensuring the integrity of the well in the well.

"This has benefited from the continuous support of our technological innovation in recent years. Advanced and some leading levels of leading levels, 57 complex deep well series engineering technologies, all transformed into actual productivity! "Tan Bin, chief engineer and professor of Chuanqing Company, witnessed the birth of the new record, and said very proudly. "The Sichuan oil people will definitely bring the rice bowl of energy in their own hands and continue to march into the deepest part of the earth!"
