Salvaging Connector Stair-Shaped Hole Sand Outlet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The deposition of solid particles in the slurry within the stair-shaped salvaging hole of the petroleum instrument salvaging connector prevents the salvaging head from being in hooking fit, hindering the salvaging process and complicating the replacement or repair of petroleum instruments during drilling.
Innovation Solution
A petroleum instrument salvaging connector with a blind stair-shaped salvaging hole featuring a large-caliber section at the bottom, a hooking face, and sand outlets at the sidewall to discharge slurry and prevent particle deposition, along with a pulley for lifting assistance, made from corrosion-resistant beryllium copper material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the stair-shaped salvaging hole is used for hooking fit, then the salvaging head can be connected to the connector, but solid particles in the slurry deposit in the hole and block the hooking mechanism
Solution Approach 1:
The patent extracts the harmful solid particles from the salvaging hole by providing a sand outlet that allows particles to be discharged from the large-caliber section. This separates the hooking function (retained in the small-caliber section and hooking face) from the particle accumulation problem (resolved by extraction through the sand outlet).
Solution Approach 2:
The salvaging hole is segmented into two distinct sections: a small-caliber section for the hooking mechanism and a large-caliber section for particle discharge. This segmentation allows each section to perform its specific function optimally - the small-caliber section maintains the hooking fit while the large-caliber section with sand outlet prevents particle blockage.
2Ease of repair
If drill rods are pulled out for instrument replacement, then the damaged instrument can be accessed, but labor intensity and time consumption increase significantly
Solution Approach 1:
The petroleum instrument is equipped with its own salvaging connector that enables direct access to the instrument without requiring extraction of the entire drill rod. The instrument essentially services itself by providing the necessary connection interface for retrieval, eliminating the time-consuming process of pulling out and reassembling drill rods.
Solution Approach 2:
The salvaging connector and hooking mechanism are pre-installed on the petroleum instrument during manufacturing. This preliminary preparation allows for quick connection and retrieval when damage occurs, eliminating the need for on-site disassembly of drill rods and significantly reducing repair time.
3Ease of operation
If the salvaging head enters the stair-shaped hole with clamping pieces, then hooking fit is achieved, but deposited particles prevent the clamping pieces from unfolding and hooking
Solution Approach 1:
The sand outlet extracts deposited particles from the large-caliber section before the salvaging head attempts to enter with its clamping pieces. This continuous or periodic extraction ensures the passage remains clear, allowing the clamping pieces to unfold and hook reliably without obstruction from accumulated particles.
Solution Approach 2:
The system incorporates dynamic particle removal through the sand outlet, which can be activated by slurry flow or mechanical action during the salvaging process. This dynamic clearance mechanism ensures that even if particles accumulate, they can be removed to maintain the functionality of the clamping piece hooking action.

AI summary
The present invention discloses a petroleum instrument salvaging connector, which is set on a salvage end of a petroleum instrument, for being in hooking fit with a salvaging head of a petroleum instrument salvaging device. The petroleum instrument salvaging connector comprises a salvaging connector body (11); the salvaging connector body (11) has a stair-shaped salvaging hole; the stair-shaped salvaging hole is a blind hole and comprises a large-caliber section (111) and a small-caliber section (112); the large-caliber section (111) is located at the bottom of the stair-shaped salvaging hole, and a hooking face (113) facing the bottom of the large-caliber section (111) is formed at the jointing part between the large-caliber section (111) and the small-caliber section (112); and a sand outlet (116) is set at the bottom of the sidewall of the large-caliber section (111). The invention further discloses a petroleum instrument. By employing the above solutions, the problem in the current drilling process may be solved that the salvaging head cannot be in hooking fit with the petroleum instrument salvaging connector due to the deposition of solid particles in the slurry in the stair-shaped salvaging hole of the petroleum instrument salvaging connector.
