Description

Technical Field

[0001] The utility model relates to the technical field of petroleum engineering, and in particular to a tool for releasing a full-size GS type bailer. Background Art

[0002] GS is one of the most common tools in wireline operation and salvage operation, and is mainly used for the placement and salvage of internal salvage tools. Wireline operation has been widely used in oilfield production due to its advantages of simplicity, convenience and efficiency. As the most common salvage tool, GS has a wide range of application scenarios and has become a must-have tool in every wireline tool box.

[0003] When salvaging downhole tools, lower the GS above the downhole tools, and use the gravity of the entire tool string to overcome the force of the internal fishing claw spring, so that the lower fishing claw of the GS enters the inside of the downhole tool salvage diameter, and then the internal fishing claw spring keeps squeezing the fishing claw to keep it in the salvage position, and then lift the tool, the downhole tool will be caught by the fishing claw, and the downhole tool will be salvaged by the jar upward. When releasing the tool, install the downhole tool on the fishing claw of the GS at the wellhead, lower the tool to the position of the working barrel to be released by the steel wire, and use the jar downward to cut off the pin inside the GS, release the upper spring, so that the upper spring pushes the tool core shaft downward, so that the fishing claw is in the release position, the fishing claw shrinks, and the downhole tool can be released.

[0004] After the GS has been salvaged from the downhole tool, it is generally necessary to use the hand to pull the salvage claw fixing component upward through the circular hole on the outside of the tool to compress the spring, so that the salvage claw moves up to the release position, thereby removing the downhole tool. If you wear gloves every time you pull the salvage claw, it is not easy to get stuck because the circular hole on the outside is too small. Pulling it directly with your hands can easily cause hand injuries. When releasing a larger GS, the force required to overcome the spring to manually release the GS will also increase due to the large spring force, making it difficult for ordinary people to disassemble it. If the salvaged downhole tool is too long, the lower tool cannot be lifted out of the blowout prevention system when releasing the tool at the wellhead. Since the upper tool string cannot face the blowout prevention system, the tool will tilt, and when releasing the GS, friction between the salvage claw and the outer wall will be generated, thereby increasing the force required to release the GS, making it difficult to release the tool.
