Problems solved by technology

[0002] At present, logging instruments that can directly measure downhole include formation testers and sidewall coring tools, but these instruments have single functions, and separate operations take up a long time and are inefficient.
This type of instrument is prone to special situations such as cable adsorption and instrument jamming in the underground, and its reliability is low

Embodiment Construction

[0032] In describing the present invention, it is to be understood that the terms "center", "longitudinal", "transverse", "left", "right", "inner", "outer", "side", "one end", The orientation or positional relationship indicated by "one side" is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, Constructed and operative in a particular orientation and therefore should not be construed as limiting the invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features. ...

Abstract

The invention discloses a well logging robot system and a well logging method. A core analysis module and a fluid analysis module are arranged on two sides of a drilling measurement module, and the core analysis module is connected with a cable stuck releasing module through a first instrument stuck releasing module. The fluid analysis module is connected with a second instrument stuck releasing module through a fluid sampling module, the drilling measurement module is used for performing sidewall coring, rock breaking and deep drilling, measurement and formation testing, and the core analysismodule is used for measuring a core. The fluid analysis module is used for fluid analysis, and the fluid sampling module is used for fluid storage. The first instrument stuck releasing module and thesecond instrument stuck releasing module are used for axially moving the well logging robot system, and the cable stuck releasing module is used for performing jarring stuck releasing on a cable. Thewell logging robot system has a high function integration degree and reliable work and obviously improves the well logging efficiency.

Description

technical field [0001] The invention belongs to the technical field of downhole operation intelligence, and in particular relates to a well logging robot system and a well logging method. Background technique [0002] At present, the logging instruments that can directly measure downhole include formation testers and sidewall coring tools. However, these instruments have single functions, and separate operations take a long time and are inefficient. This type of instrument is prone to special situations such as cable adsorption and instrument jamming in the underground, and its reliability is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a logging robot system and a logging method for the deficiencies in the above-mentioned prior art, which can drill the stratum, measure directly in the hole, take cores, and perform core logging. For measurement, pressure testing of formation fluids can be carried out, fl...
