Storage type well logging blowout prevention connector

Abstract

The invention discloses a storage type well logging blowout prevention connector, and belongs to the technical field of well logging devices. The storage type well logging blowout prevention connector. The connector comprises a circulation section, one end of the circulation section is provided with a first connecting end used for being connected with a single blowout preventer, the other end of the circulation section is provided with a second connecting end used for being connected with a protective sleeve, an inner cavity of the circulation section is of a hollow structure, and a pluralityof circulation holes are formed in the side wall of the circulation section. Through the first connecting end and the second connecting end, positioning can be achieved, the protective sleeve and a blowout prevention single pipe of a drilling crew are rapidly connected, through the arrangement of the circulating holes used for circulating slurry, construction safety is guaranteed, through a variable-diameter structural design, hoisting connection operation is facilitated when well control dangerous cases happen, and the installation efficiency is improved. According to the storage type well logging blowout prevention connector, well control dangerous cases can be coped with, construction safety is guaranteed through rapid connection, well killing operation is facilitated, and the problem that potential safety hazards exist after well control risks occur when a well mouth is connected with a protective sleeve traditionally is effectively solved.

Description

technical field [0001] The invention belongs to the technical field of logging devices, and relates to a storage type logging blowout prevention joint. Background technique [0002] Cableless storage logging is a new type of drilling tool conveying logging technology, which provides the same logging data as wireline logging without the need for cables to connect downhole tools. When logging and installing the wellhead, it is necessary to connect the protective sleeve first, and then connect the instrument in the protective sleeve. After the connection is completed, it is suspended in the protective sleeve through the releaser, located in the lower annulus of the drilling tool, and transported to the bottom of the well with the drilling tool. After the end, the instrument is released from the drilling tool by mechanical or numerical control and hangs on the bottom of the drilling tool. When tripping out, the tool collects formation data to complete logging. [0003] Storage...
