Abstract
The invention provides a through diameter process of a vertical pipe. The through diameter process comprises the following steps of: 1, sequentially connecting steel wire ropes, a round log guide and a buckling detector on the ground into a whole body in sequence, so as to form a through diameter device; 2, respectively arranging winches and a pulley wheel at setting positions of the two sides of the vertical pipe; 3, threading a thin rope from the high end of the vertical pipe to the lower end and pulling the steel wire rope on the winch at the lower end to the high end through the thin rope; 4, connecting the steel wire rope on the through diameter device with the steel wire rope on the winch at the lower end; then placing into the vertical pipe and threading the other end through the pulley wheel to be connected with the steel wire rope on the second winch; and 5, starting the winch at the lower end and pulling the buckling detector to carry out diameter measuring work in the vertical pipe; and meanwhile, releasing the steel wire rope by the second winch and keeping the steel wire rope to be at a pre-tightening state until the buckling detector is pulled to the front end from the tail end of the vertical pipe. The through diameter process guides a round log so that a through diameter ball smoothly passes through a bent pipe, so that that the result of the through diameter of the vertical pipe can be accurately judged, and the safety and the reliability of through diameter operation are improved.
Description
Technical field
The present invention relates to standpipe, relate in particular to a kind of latus rectum technique of standpipe.Belong to the Offshore Engineering field.
Background technology
At sea in the petroleum development engineering, need to be at submarine laying pipeline under the ocean and submarine cable.Pipeline under the ocean comprises: flat pipe, platform standpipe and expansible bend, platform standpipe are the chief components that connects flat pipe and Shunping County, pipeline termination platform member is drawn the water surface.After at sea the oil field was constructed and put into operation, because the foundation of the further exploitation in oil field and new platform needs to set up newly-increased submerged pipeline and newly-increased cable, this just need to install newly-increased standpipe and cable protecting tube at the jacket of active service platform.And standpipe normally prefabricated on the coast after, transport on the offshore platform again and install.Yet, after standpipe is prefabricated, need to carry out latus rectum to standpipe, in case the distortion that occurs at prefabricated spreading process neutral tube or cause internal diameter to diminish because overlap is excessive etc., thereby after causing going into operation, can not normally receive and dispatch the ball operation.Standpipe drifting method commonly used has two kinds: the one, make easy transmitting-receiving ball device, and pass through standpipe with air pressure or hydraulic drives Flection detector, finish latus rectum; The shortcoming that the method exists is as follows:
1. owing to need air pressure or hydraulic drives, require the diameter measurer edge seal, and this kind installation cost is higher, thereby, cause expense higher;
2. owing to need at standpipe first and last end shutoff and valve etc. to be installed, do interim transmitting-receiving ball device, thereby, waste of material caused;
3. need to be with press operation during latus rectum, larger security risk is arranged;
4. area of isolation is larger when operating, and takies larger place resource.
5. owing to use winch and wire rope to draw Flection detector to pass through standpipe, finish latus rectum, be out of shape easily during by bend pipe at way radial ball, thereby, cause the latus rectum result to differentiate.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of latus rectum technique of improved standpipe, it is using the dilatory way radial ball of winch and wire rope to carry out on the basis of latus rectum, use wooden the guiding, can allow way radial ball pass through smoothly bend pipe, thereby, can accurately differentiate the result of standpipe latus rectum; Reduce cost of production, improved safety and the reliability of latus rectum operation.
The objective of the invention is to be realized by following technical scheme:
A kind of latus rectum technique of standpipe is characterized in that: adopt the following step:
The first step: wire rope, round log guiding, Flection detector are connected successively on ground in order and be integrated, consist of a drift diameter device;
Second step: on the desired location of standpipe both sides, arrange respectively winch, pulley;
The 3rd step: wear a cord from standpipe is high-end to low side first, move to the wire rope on the First winch that is positioned at low side high-end by cord;
The 4th step: the wire rope on the drift diameter device that assembles is connected with wire rope on the First winch that is positioned at low side, then, puts into standpipe, the other end then passes pulley and is connected with wire rope on second winch;
The 5th step: start the First winch that is positioned at low side, the pulling Flection detector is calibrated operation in standpipe; Simultaneously, second winch put wire rope, and keeps wire rope to be in Pre strained state, until Flection detector is pulled to head end from the end of standpipe, namely finishes and once calibrates operation.
An enforced loop plane is respectively installed in the both sides of described round log guiding, and the enforced loop plane outside is equipped with a steel wire clamp with the wire rope junction.
Beneficial effect of the present invention: the present invention is owing to adopt technique scheme, it uses wooden the guiding using the dilatory way radial ball of winch and wire rope to carry out on the basis of latus rectum, can allow way radial ball pass through smoothly bend pipe, thereby, can accurately differentiate the result of standpipe latus rectum; Reduce cost of production, improved safety and the reliability of latus rectum operation; And simple in structure, do not require that the Flection detector edge is close; Easy to operate, reduced prefabricated work; During the latus rectum operation, do not need with pressure carrying out, safe operation process is reliable; Dwindle the zone that needs isolation, saved the place resource.
