Abstract
The utility model provides a flange public awl, including top connection (1), flange (2) and public awl body (3), top connection (1) upper portion is provided with the screw thread that is connected with the drilling string, and top connection (1) lower part passes through threaded connection with public awl body (3), flange (2) pass through threaded connection earlier with public awl body (3), and rethread welding is fixed. Compare original public awl, flange public awl, have the well head concurrently and prevent blowout and salvage two kinds of functions in the pit, be a composite tool that can both use in the pit on the well, advanced, the safe and reliable of structure.
Description
Flange male cone
Technical Field
The utility model belongs to the technical field of oil well head and fishing tool, in particular to flange male cone.
Background
The special tools for the oil field comprise wellhead tools for the oil field and underground tools for the oil field, and few tools which can be used underground and underground are available.
The male tap belongs to one kind of petroleum fishing tool, and is one kind of fishing tool for making thread from oil pipe, drill rod, milling pipe, production allocator and other inner hole with hole. The existing male tap only has a fishing function and belongs to an underground operation tool.
Disclosure of Invention
The utility model aims at developing a collect well head and prevent blowout and salvage function in the instrument of an organic whole in the pit, provide a flange public awl.
The utility model aims at realizing through the following technical scheme:
the utility model provides a flange pin cone, includes top connection, flange and pin cone body, top connection upper portion is provided with the screw thread that is connected with the drilling string, and the top connection lower part passes through threaded connection with the pin cone body, flange and pin cone body pass through threaded connection earlier, and rethread welding is fixed.
The utility model discloses compare prior art's beneficial effect does:
compare original public awl, flange public awl, have the well head concurrently and prevent blowout and salvage two kinds of functions in the pit, be a composite tool that can both use in the pit on the well, advanced, the safe and reliable of structure.
Drawings
Fig. 1 is the structural schematic diagram of the male cone of the flange of the present invention.
Detailed Description
As shown in fig. 1, the present embodiment provides a flange male cone, which includes an upper joint 1, a flange 2 and a male cone body 3, wherein a thread connected with a drill string is provided on an upper portion of the upper joint 1, a lower portion of the upper joint 1 is connected with the male cone body 3 through the thread, and the flange 2 is connected with the male cone body 3 through the thread and then fixed through welding. The top sub can transmit weight on bit and torque to the male cone body 3.
The working principle is as follows:
and after the upper joint female buckle is connected with the upper drill string, slowly lowering the drill string, and applying certain bit pressure and torque to the drill string when the male cone body of the male cone flange enters an oil pipe or a drill rod, so that the male cone starts to make a buckle.
After the buckle making is completed, the drill stem can be lifted up to realize the fishing function. The male cone is not provided with a cutting groove, and the male cone and an oil pipe or a drill rod are tightly connected together to form metal seal after the thread is made. And (4) removing the upper connector with the male cone flange, and connecting the flange with the flange of the upper pipeline to form a sealed channel to realize the blowout prevention function.
Claims (1)
1. The flange male cone is characterized by comprising an upper connector (1), a flange (2) and a male cone body (3), wherein threads connected with a drill string are arranged on the upper portion of the upper connector (1), the lower portion of the upper connector (1) is in threaded connection with the male cone body (3), and the flange (2) is firstly in threaded connection with the male cone body (3) and then is fixed through welding.
