Abstract
The invention relates to a protective device for a directional penetrating pipeline. The problems that the penetrating pipeline is crushed, damaged and locally deformed are solved. According to the technical scheme, a protective pipeline is arranged outside the penetrating pipeline in a sleeved mode, the length of the protective pipeline is equal to that of the penetrating pipeline needing to be protected, a sealing ring and a slip are arranged at the two ends of a protective pipeline, fluid is filled into a circle between the protective pipeline and the penetrating pipeline, and the pressure of the fluid is smaller than that of internal media in the penetrating pipeline. The slip and the sealing ring seal the annular fluid and tightly hold the penetrating pipeline. The penetrating pipeline is effectively protected, the situation that pipeline is crushed, broken, injured by a crashing object and locally deformed due to wellbore instability is avoided, the penetrating pipeline is prevented from being repaired or replaced or penetrating a new pipeline again, and the protective device is especially suitable for protecting pipelines penetrating through rivers, gravel layers, soft and hard connecting strata, faults and easily-collapsing strata and the like.
Description
Technical field
The present invention relates to directional traversing pipeline protective equipment in a kind of oil, rock gas field, be specially adapted to the staggered stratum in river crossing, soft or hard, gravel layer, tomography, easily the subside pipe protection on stratum.
Background technique
Along with the development of China's pipeline industry, the non-excavation of pipeline passes through more and more and comes into one's own, and utilizes the horizontal directional drill of pipeline special use to carry out crossing construction, has become a kind of major way of Pipeline Crossing Program.This mode not only can, for the passing through of river and water channel, also be widely used in passing through of expressway, railway, airport, seashore, island, massif, tropical rain forest and densely covered building, historic reservation, pipeline compact district etc. simultaneously.Such as pipeline of transferring natural gas from the west to the east passes through desert, Gobi desert, mountain area, hills, Plain, basin, loess plateau, the network of rivers, the south of the River, great rivers and a large amount of farmlands etc., particularly pipe passes through the Yellow River 3 times, pass through the Changjiang river, Huaihe River each 1 time, also wear in addition (across) other Large River more than 10 times.This directional traversing mode is compared with other non-digging modes, there is traverse velocity fast, save construction cost, the advantages such as drilling diameter and crossing pipeline diameter ratio are little, but this mode of passing through is subject to the restriction of geological condition larger, as the stratum such as boulder bed, drift sand formation are difficult to pore-forming, while passing through, need a large amount of mud etc.After Pipeline Crossing Program success, due to Geological Reasons, often there are the damage, obstruction of pipeline etc., thereby cause oil gas to carry, interrupt or leak.Particularly there are hard rock or soil property in river crossing, hills etc. compared with soft formation, or meet the reasons such as landslide, debris flow, human-generated explosives and cause borehole well instability, subside etc., easily cause the accidents such as injuring by a crashing object, shrivel of crossing pipeline, affect oil gas and normally carry.And for reparation, the replacing of inefficacy pipeline or again creep into and pass through the time that new pipeline need to be longer; thereby, how to protect crossing pipeline, reduce and avoid crossing pipeline reparation, change or avoid again passing through new pipeline and become researcher and engineers and technicians and guarantee the normal important topic of carrying of oil gas.For this reason, designing a kind of protective equipment for crossing pipeline has great importance to the normal operation of oil and gas pipes.
Summary of the invention
The object of the invention is: in order to overcome crossing pipeline in existing oil, rock gas field, failure phenomenon easily occurs; spy provides a kind of crossing pipeline protective equipment; it is for the protection of underground directional traversing pipeline; can effectively solve the crossing pipeline Problem of Failure causing due to outside causes such as geology, landslide, debris flow, human-generated explosives, realize long-term normal conveying of crossing pipeline.
To achieve these goals, the present invention is by the following technical solutions: directional traversing pipeline protective equipment, by crossing pipeline, end housing, end cap, screw, thickening pipeline, protection pipeline, supporting section, baffles, seal ring, slips, formed, it is characterized in that: protection pipeline is enclosed within crossing pipeline outside, the length that the total length of protection pipeline equals to need protection in crossing pipeline, each protects between pipeline with being welded to connect, protection pipe end with thickening pipeline with being welded to connect; Near protection pipe interior welding position arranges supporting section, supporting section is comprised of upper preload piece, lower preload piece and slips, upper preload piece is connected with screw with lower preload piece, upper preload piece all contacts with inclined-plane with slips with lower preload piece, lower preload piece and protection pipeline are with being welded to connect, the external diameter of upper preload piece is less than the internal diameter of protection pipeline, has realized slips to the support of crossing pipeline and hold tightly under pretightening force effect; On thickening pipeline, offer fluid input, annular space between protection pipeline and crossing pipeline is full of fluid, the pressure of fluid is less than the interior media pressure of crossing pipeline, and because the slips in supporting section exists gap, fluid can connect mutually by each supporting section; Thickening pipeline is connected with end cover screw, and thickening pipe interior is installed baffles, between baffles and slips, adds seal ring, realizes the axial seal to annular fluid; End cap is connected with inclined-plane with slips, under the effect of screw power, realizes holding tightly of slips and crossing pipeline, and to overcome the frictional force that protecting tube pipeline outer wall produces in pulling process, slips is identical with the inclined-plane slope of end cap, upper preload piece, lower preload piece; End housing is with screw or be welded to connect in end cap end, at pipeline, pulls in process and can reduce surface friction drag.
The invention has the beneficial effects as follows: the protection pipeline that (1) this directional traversing pipeline protection device adopts can be protected crossing pipeline effectively, avoid, because of accidents such as borehole well instability causes crossing pipeline generation conquassation, injures by a crashing object, partial fracture, guaranteeing long-term normal conveying of oil gas in crossing pipeline; (2) annular space of this directional traversing pipeline protection device is full of fluid, can avoid causing because of the partial failure of protection pipeline the discontinuity of crossing pipeline; (3) sealing configuration in this directional traversing pipeline protection device is reliable, shutoff annular fluid effectively.(4) this directional traversing pipeline protection device take up room little, simple in structure, arrange flexibly, to long, apart from any position of crossing pipeline, all can realize good protection.
