Our Achievements 2025.04.19

In 2009, we developed T-type drilling technology. From then on, We constantly develop and improve technology in the oil-field application. Now, the ninth generation of drilling product has been made and the technology is gradually mature.As of the year 2022, our company has provided 122 T-type drill

What can this technology do? 2025.04.19

Application 1: Tapping the potential of remaining oil in old oilfieldsDrilling through the pollution zone near the well;Penetrating the remaining oil or dead oil areaIncrease oil drainage area and seepage channels;Improve reservoir connectivity;Application 2: Developing low-permeability or thin rese
What are the advantages of T-type drilling? 2025.04.19

Advantage 1: Super-short deviation radiusAdvantage 2: Layer can be developed by multi branchAdvantage 3: The trajectory of branch can be controlledWe controll the T-shaped hole trajectory in the below three stages.Window opening stage: the deflector determines the azimuth and angle.Deviation b
