my country's first Wanmike exploration well Shendi Take 1 drilled more than 8,000 meters

In recent years, PetroChina has accelerated the promotion of high-level scientific and technological self-reliance and continued to research ultra-deep and ultra-deep well drilling and completion technologies, and has drilled two wells with a depth of 10,000 meters. In the five months since drilling began, thanks to the integrated collaboration of drilling, exploration, and geology, Well Shenzhen Tako 1 has not only achieved 100% qualification rate in key wellbore quality indicators such as well inclination, well diameter, cementing, and logging. , and during the second and third opening cementing casing operations, it set many records such as the deepest large-size casing and the largest casing tonnage in my country.

At present, the formation temperature of the well has exceeded 155 degrees Celsius, and the pressure has exceeded 110 MPa. "During the subsequent drilling process, we are still faced with a series of technical difficulties such as difficult-to-drill formations, extreme working conditions, and complex pressure systems." said the drilling director of the Tarim Oilfield Supervision Center.

In this regard, Tarim Oilfield has broken the traditional "professional division and management division" drilling organizational form, built an interdisciplinary working platform, promoted the integration of geology and engineering, scientific research and production, and transformed drilling. , exploration, geology and other "small teams" are called "group armies". In the invisible and intangible deep underground, technicians dynamically adjust drilling tools and parameters according to geological conditions, tailor drilling tool combinations and engineering technology countermeasures for each set of strata and each well section, and constantly break through the "depth" of engineering technology. limit".
