Patent CA-2941605-A1 (CA)
Inventor: YI HUIAN
IPC: E21B33/12
Filed: 2012-07-23
Abstract: A liner hanger top packer comprising a main body (10) and, sleeved sequentially from top to bottom on the main body, an adjusting sleeve (20), a retaining apparatus (30), a base-sealing apparatus (40), a base-hanging apparatus (50), and a locking mechanism (60) arranged between the base-sealing apparatus (40) and the base-hanging apparatus (50). The locking mechanism (60) comprises a locking ball sleeve (61), a ball socket (62), and a steel ball (63). During a descent process, as the lower part of the liner hanger top packer is met with friction, the arrangement of the steel ball (63) restricts relative axial movements between an upper gauge ring (41) of the base-sealing apparatus (40), the locking ball sleeve (61), and an upper conical body (51) of the base-hanging apparatus (50), therefore, the friction transmitted to the upper conical body (51) is not transmitted to a lower gauge ring (43) of the base-sealing apparatus (40), but is transmitted directly to the upper gauge ring (41) via the steel ball (63), and is further transmitted to the adjusting ring (20) via the retaining apparatus (30). As such, relative movements are not generated between the upper gauge ring (41) and the lower gauge ring (43), while a plastic cylinder (42) does not deform, thus preventing the possibility to premature base-sealing.

Filed: 2016-03-24
Abstract: There is described a method and system for obtaining results from one or more data sources without the need to extract, transform and load the data into a database prior to performing a query. The data may retain its original format and remain in its initial location, and selective access to the data is provided using dynamically generated query statements. Multiple data sources may be accessed concurrently, each data source having its own format for stored data. Query statements are generated to obtain data (query results) from the various data sources by defining data sources, target fields, and parameters to be used for a given query. The statements comprise predefined operations that are applied recursively in order to transform (and sometimes aggregate) the data from the data sources into query results. Query statements and query results may be saved for later use.
