In April, the first batch of oil production wellheads, packers,
hydraulic double-diameter drill stabilizers and other products produced by our company were delivered to customers.

Our company’s first gas production wellhead was officially installed in Changqing Oilfield and put into commercial application

Our company developed the technology of replacing wellhead gate valve under pressure
And successfully passed the field test for the first time, and the pressure technology service was promoted

On April 6, the technical service team of our company carried out the operation of drilling through the gate
valve gate under pressure at the gas production wellhead and replacing the out-of-control gate valve in Changqing Oilfield, which was a complete success

It marks the first application of this technology in oil and gas fields in my country

Our company cooperated with PetroChina to develop hydraulic sandblasting fracturing technology,
and successfully passed the ground and downhole tests, which is the first time in China

In July, our company replaced a gas production wellhead gate valve with a H2S content of more than 30000mg/m3 under pressure.
