Publication number: 20230359500Abstract: Example embodiments of the present disclosure relate to computing system management. A plurality of previous workloads of a computing system for a previous time duration are obtained. Workload estimation is determined for a future time duration based on the plurality of previous workloads. Based on the workload estimation, management profile is selected from a group of management profiles for managing the computing system for the future time duration. With the example embodiments, the computing system is managed in a flexible and effective way.Type: ApplicationFiled: October 21, 2020Publication date: November 9, 2023Inventors: Xinmiao LI, Wei CHEN, Huanqiu YE, Xianhua HE, Jun HE, Kefeng LIU

Patent number: 11697970Abstract: A directly connected drill pipe applicable to extreme conditions includes a tool joint pin and a tool joint box, where an external pipe section is located on an external side of a threaded section of the tool joint pin, and an annular groove is formed between the external pipe section and the threaded section of the tool joint pin. An insertion section of the tool joint box can be inserted into the annular groove in a matched manner. A main shoulder of the tool joint pin is located at an end of the external pipe section, a main auxiliary shoulder of the tool joint pin is located on a bottom surface of the annular groove, and an auxiliary shoulder of the tool joint pin is located at a small end of the tool joint pin. The tool joint box has three corresponding shoulders which form a 3-stage sealing with the tool joint pin.Type: GrantFiled: January 19, 2021Date of Patent: July 11, 2023Assignee: INSTITUTE OF EXPLORATION TECHNIQUES, CHINESE ACADEMY OF GEOLOGICAL SCIENCESInventors: Hao Yin, Jian Liang, Xinmiao Li, Jianhua Sun, Kuan Li, Xiumei Liu

Patent number: 11326413Abstract: A wire-line core drilling tool includes an outer barrel assembly and an inner barrel assembly. The inner barrel assembly is provided with an elastic clamp positioning mechanism, an in-place reporting and core blockage alarm mechanism, a single-action mechanism, a core barrel check valve mechanism, a core barrel and a core-breaking mechanism. The elastic clamp positioning mechanism adopts a multi-point hinged mode. The in-place reporting and core blockage alarm mechanism is integrally formed. The single-action mechanism adopts a cooperating structure of an upper polycrystalline diamond compact (PDC) bearing, a lower PDC bearing and a tungsten carbide (TC) bearing arranged in the middle. The outer barrel assembly is provided with an elastic clamp retaining head, an elastic clamp chamber, an upper reamer, an outer barrel, a lower reamer and a drill bit. A ring base is arranged, and a centralizing ring is arranged.Type: GrantFiled: September 16, 2020Date of Patent: May 10, 2022Assignee: INSTITUTE OF EXPLORATION TECHNIQUES, CHINESE ACADEMY OF GEOLOGICAL SCIENCESInventors: Xinmiao Li, Jian Liang, Kuan Li, Hao Yin, Xiumei Liu
