Problems solved by technology

However, the above-mentioned release method is not suitable for oil and gas wells with large well deviation
When the release tool drives the downhole tool to move to a position with a large inclination in the oil and gas well, the vibration force cannot be effectively transmitted to the connection between the release tool and the downhole tool, resulting in the failure of the pins connecting the release tool and the downhole tool to break, resulting in downhole tools. Can't disengage casting tool

Abstract

The invention relates to the technical field of natural gas and oil exploitation, and discloses an applicator. The applicator comprises a shaft body, a base body, clamping arms, a clamping jaw and locking mechanisms; a working cavity extending along the axis of the shaft body is formed in the shaft body, extends to one end of the shaft body and forms an opening communicated with the outside; the base body is arranged in the working cavity; the two clamping arms are symmetrically arranged in the working cavity along the axis of the shaft body, and the fixed ends of the clamping arms are fixedly connected with the base body; the clamping jaw is arranged at the movable ends of the clamping arms; the two locking mechanisms are correspondingly arranged on the two clamping arms; the locking mechanisms are configured to be capable of being matched with each other when the movable ends of the two clamping arms are located at the clamping positions so that the movable ends of the two clamping arms can be maintained at the clamping positions; and the locking mechanisms are configured to be capable of being separated under the action of external force when matched with each other. The applicator is suitable for oil and gas wells with large well deviation, and downhole tools connected to the applicator can be reliably released at the positions with large inclination in the oil and gas wells. The invention further discloses a downhole tool string comprising the applicator.

Description

technical field [0001] The present application relates to the technical field of natural gas and oil exploitation, in particular to an applicator and a downhole tool string. Background technique [0002] Currently, when a downhole tool is lowered into an oil and gas well, the deployment tool is connected to the downhole tool through pins. After the downhole tool is lowered to the predetermined position in the oil and gas well through the release tool, the pin is broken by vibration, so that the release tool and the downhole tool are separated, and the downhole tool remains at the predetermined position of the oil and gas well. However, the above-mentioned release method is not suitable for oil and gas wells with large well deviation. When the release tool drives the downhole tool to move to a position with a large inclination in the oil and gas well, the vibration force cannot be effectively transmitted to the connection between the release tool and the downhole tool, resul...
