According to the news broadcast(CCTV), on February 20, China drilled a 10000 meter deep well in the Taklimakan Desert, with a depth of 10910 meters. The well below 10000 meters also has high-quality oil and gas, which is the first 10000 meter deep oil and gas well in the world.
To drill a deep well of 10000 meters on Earth, the drill bit must withstand an atmospheric pressure of 145 megapascals and a high temperature of over 220 degrees Celsius. Under such high temperature and pressure conditions, new challenges have been posed for the validation of cementing operations and cement additive formulations. In the laboratory of China Petroleum Xinjiang Cementing Company, the cementing test instruments were supplied by Shenyang Taige Oil Equipment 5 years ago. These reliable instruments cover HTHP consistometer, HTHP curing chamber and other cementing test equipment, which ensure sufficient inspection and verification of the cementing addition formula, thus successfully completing the cementing operation of the entire 10000 meter deep well.
