Abstract: An auxiliary system for intelligent well control includes augmented reality (AR) glasses, a server, and a first sensor group. The first sensor group is configured to collect real-time data of a wellbore and the surface and transmit the real-time data to the server. The server is configured to analyze a target pressure value of a choke valve of the surface according to the real-time data, obtain an actual pressure value of the choke valve of the surface from the real-time data, and transmit the actual pressure value and the target pressure value to the AR glasses. The AR glasses are configured to dynamically display the actual pressure value and the target pressure value in real time. Through the first sensor group and the server, the actual pressure value and the target pressure value can be accurately received by an operator in real time.

Abstract: An ultra-high expansion downhole packer includes an anchor, a primary expansion cone, and a central tube. The anchor is provided with a first tapered through-hole having a large end sleeved at a small end of the primary expansion cone. The anchor is radially expandable to anchor with an inner wall of a wellbore. The primary expansion cone is provided with a second tapered through-hole, and the second tapered through-hole has a large end sleeved at a small end of the central tube. The primary expansion cone is a radially expandable structure, and the primary expansion cone supports the anchor after an expansion. The primary expansion cone is provided between the anchor and the central tube. The primary expansion cone is first driven into the anchor to make the anchor radially expand, and then the central tube is driven into the primary expansion cone to make the anchor radially expand again.

Abstract: A ball seat configured for multistage stimulation in oil and gas wells includes bottom sub, slips, sealing element and mandrel. The mandrel is a cone frustum, and it's exterior is encased by the sealing element and slips. One end of the sealing element is attached to one end of slip, the end of the cone frustum mandrel with the smallest exterior diameter is completely encased by slips. One end of the bottom sub is attached the other end of the slip. The bottom sub includes a threaded shearing connecting structure, which is designed to connect the setting tool adaptor used to deploy the ball seat into the oil or gas well. The sealing element is a two-segment structure, the hardness of the first segment is lower than that of the second segment.
