Description
Technical Field
The utility model belongs to the technical field of the marine oil gas is bored and is adopted and specifically relates to a hammer into formula water proof pipe and take place to beat the device.
Background
The offshore riser pipe well descending mode is generally divided into a drilling type, a hammering type and a spraying type, the well descending is generally carried out by adopting the hammering method aiming at the well conditions that the water depth is 150 meters and the mud is less than 80 meters, the well drilling cost is saved, the operation time is short, and the operation time efficiency is high. The riser pipe is hit into mud through the pile hammer and gets into design well position, because pile hammer impact energy is big, hits the hitting down in the well and hits the number of times many, directly hits riser pipe and can exert an influence to riser pipe straightness accuracy, circularity and structure, leads to whole pipe cluster to warp the destruction when serious.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects of the prior art and provide a hammering type riser replacing device.
The utility model discloses new technical scheme is: hammer into formula riser pipe and take place to beat device, including reducing head, take place to beat tup, body and hole for hoist, the reducing head be the cone, reducing head one end welding take place to beat tup one end, and take place to beat the tup and be equipped with the circular bead, take place to beat the tup other end welding and have the body, the pipe end of body be equipped with the hole for hoist.
The reducing head is formed by rolling a pipeline steel plate.
The length of the reducing head is 250mm-350mm, and the thickness of the reducing head is 15.9mm-22 mm.
The reducing angle of the reducing head is 13-21 degrees.
The replacement hammer is provided with 2 shoulders.
The replacing hammer head is low alloy.
The pipe body is formed by rolling and welding pipeline steel plates.
The length of the pipe body is 1.6-2 m.
The utility model has the advantages that: the cone structure of the reducing head of the utility model is beneficial for the replacing device to be quickly led into the riser string, and the thread buckle of the riser is not easy to be damaged in the leading-in process; the forging hammer head and the reducing head are separately processed, only the forging hammer head is a low-alloy forging piece, the processing difficulty is reduced, and the cost is saved; the hardness of the replacing hammer head is slightly lower than that of the conduit threaded joint through quenching and tempering treatment, and the threaded joint is protected; the pipe end of the pipe body is provided with hoisting holes, so that the hoisting is convenient and fast.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is the structural schematic diagram of the utility model installed in the water-proof conduit.
Wherein: 1. reducing head, 2, take over and beat the tup, 3, body, 4, lifting hole.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
Hammer into formula riser and take place to beat device, including reducing head 1, take place to beat tup 2, body 3 and hole for hoist 4, reducing head 1 be the cone, 1 one end welding of reducing head take place to beat 2 one ends of tup, and take place to beat 2 tups and be equipped with the circular bead, take place to beat 2 other end welding of tup and have body 3, the pipe end of body 3 be equipped with hole for hoist 4.
The reducing head 1 is formed by rolling a pipeline steel plate.
The length of the reducing head 1 is 250mm-350mm, and the thickness of the reducing head 1 is 15.9mm-22 mm.
The reducing angle of the reducing head 1 is 13-21 degrees.
The secondary beating hammer head 2 is provided with 2 shoulders.
The forging hammer head 2 is made of low alloy.
The pipe body 3 is formed by rolling and welding pipeline steel plates.
The length of the pipe body 3 is 1.6-2 m.
Hammer into formula riser pipe and take place to beat the device, reducing head 1 is rolled up with the pipeline steel sheet and is formed, welds on taking place to beat tup 2, avoids the tup whole forging processing degree of difficulty big, with high costs. The cone structure of the reducing head 1 is beneficial to the replacing drilling device to be quickly led into the riser pipe string, and the thread buckle of the riser pipe is not easy to damage in the leading-in process. The replacing hammer head 2 is designed with a circular bead surface according to the riser joint, is provided with two circular beads, is integrally made of low alloy, has hardness slightly lower than that of the riser threaded joint after quenching and tempering, and can effectively protect the threaded joint when the piling hammer is used for hammering. The pipe body 3 is formed by rolling and welding pipeline steel plates, has the length of 1.6-2 meters, and is suitable for hoisting operation on a deck of a drill floor and mounting and dismounting with piling equipment. 3 pipe end processing hoisted hole 4 of body, the lug of avoiding welding form is bearing the multiple hammering in-process and droing.
The working principle is as follows:
before the construction of the piling operation, the steel wire rope passes through the hoisting hole 4 to be connected with the piling hammer. When the pile driving operation is carried out, the hammering short section is inserted into the female joint, then the top of the replacing device is hammered, so that a hammerhead or a pile cap of the pile driving device does not directly act on the joint of the waterproof guide pipe, and the unsmooth butt joint of the subsequent waterproof guide pipe caused by stress deformation of the joint of the waterproof guide pipe can be avoided.
