Abstract

The invention provides a downhole instrument support tube, which comprises a support tube main body and a connecting box, wherein a plurality of installation grooves for accommodating downhole instruments are formed in the outer side wall of the support tube main body; the connecting box is arranged on the support tube main body and is provided with a connecting cavity communicated with the plurality of installation grooves. According to the downhole instrument support tube, the plurality of downhole instruments are arranged in the plurality of installation grooves in the outer side wall, the connecting box is arranged on the support tube main body, and wires of the downhole instruments can be electrically connected in the connecting cavity of the connecting box, thereby achieving communication among the downhole instruments. According to the downhole instrument support tube, electric connection among the plurality of downhole instruments can be very conveniently achieved; and in addition, the wires of the plurality of downhole instruments all are arranged in one connecting cavity, so that troubleshooting is also facilitated.

Description

technical field [0001] The invention relates to a downhole instrument holder, in particular to a downhole instrument holder in the field of oil and gas development. Background technique [0002] At present, there are two main types of downhole instrument holders (carriers) used in the fields of oil reservoir dynamic monitoring, well testing, and oil and gas well testing: one is to place downhole instruments inside the holder, which is called an internal hanging holder , this structure partially blocks the flow channel because the instrument is inside the support tube, and also restricts the passage of other instruments that use cables, which has great limitations in application; the other is to place the instrument in the support tube. External, generally called an external support tube, the specific method is to set installation grooves on the outer wall of the support tube, and place the instrument in the installation groove. In different slots, no electrical connection c...
