Latest Patents
One of Tianen Liu's key inventions is a lost circulation detection device. This device includes a first detection member and a second detection member. A first signal transmitter and a first signal receiver are disposed on the first detection member, allowing the first signal transmitter to transmit a signal along the axial direction of a rockshaft. This enables the first signal receiver to acquire data information of drilling fluid in the axial direction of the rockshaft. Additionally, a fluid channel penetrating through the second detection member is configured to communicate with the rockshaft. A second signal transmitter and a second signal receiver are positioned oppositely on either side of the fluid channel, allowing the second signal transmitter to transmit a signal along the center line of a second accommodating groove. This setup enables the second signal receiver to acquire data information of drilling fluid in the circumferential direction of the rockshaft. Tianen Liu holds 1 patent for this innovative device.
