Title:
FLUID SEPARATING DEVICE, HOISTWAY STRUCTURE, AND PETROLEUM OR NATURAL GAS PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/047872
Kind Code:
A1
Abstract:
Disclosed are a fluid separating device, a hoistway structure, and a petroleum or natural gas production method. By means of a fluid separating device (010) and a hoistway structure (020), the requirements for the intensity of a hitting force of a lower hitting device (203) on a mandrel (200) are reduced, and only a small collision force between the mandrel (200) and the lower hitting device (203) is required to complete the switching from a contracted position to an expanded position of a mandrel (200),thereby improving the reliability of the fluid separating device (010) and the hoistway structure (020) during operation.
