Abstract
The invention discloses a waste oil guiding and collecting device in a wellhead area, which consists of a conductor tube, a lower cone, an upper cylinder, half tiles, bolts, a rubber gasket, a stainless steel plate, an annular baffle, enclosing plates, a waste oil collection groove and a plate grid, wherein the conductor tube is provided with a horn-shaped sleeve; and waste oil on the surface of the horn-shaped sleeve is guided onto the steel plates, and then is recycled and treated by the waste oil collection groove. The waste oil guiding and collecting device can smoothly guide and collect the waste oil produced in workover treatment, and reduces risks in the field operation.
Description
Technical field
The invention belongs to a kind of bank greasy dirt water conservancy diversion gathering-device.
Background technology
At present the deck of laying, domestic offshore platform bank just under arms is flase floor, this be since flase floor have can be anti-skidding, lightweight, the characteristics such as need not to get angry when installing.But along with the attention of people to marine environmental protection, the problem of its generation more and more can not be ignored.Subject matter is directly dripped the sea for the greasy dirt that produces through the beam lattice in the middle of the flase floor or is flowed down along the waterproof casing outer wall when workover treatment, marine environment is caused comparatively serious pollution.Be head it off, and consider economy and convenience, the practice is that the flase floor in platform well mouth district is replaced by fluid-tight steel plate preferably.But because may there be a large amount of casing gas in the space between waterproof casing and its inner tubing and casing, as directly carrying out weld job at waterproof casing, then may produce the serious accidents such as blast or fire.Therefore, for security consideration, the new steel plate of laying generally all can not directly weld with the waterproof casing outer wall.Owing to have the slit between the two, can't stop greasy dirt to flow down along the waterproof casing outer wall.
Summary of the invention
The purpose of this invention is to provide a kind of bank greasy dirt water conservancy diversion gathering-device, at waterproof casing a trumpet type sleeve is installed, the greasy dirt water conservancy diversion that it is surperficial recycles through sewage sump to steel plate again.
The present invention is comprised of waterproof casing, bottom cone and top cylindrical shell, half-watt, bolt, rubber pad, waterproof steel plate, ring baffle, coaming plate, feeder, screen, be anchored on the trumpet type sleeve on the waterproof casing, its agent structure comprises bottom cone and top cylindrical shell two parts, and two parts are welded up and down; Divide in the plane the half-watt of two symmetries, be formed by connecting with bolt; Between top cylindrical shell and the waterproof casing rubber pad is set, between the bolt junction plate of two half-watts rubber pad is set; Be laid on the bank waterproof steel plate is set, it arranges ring baffle near waterproof casing one side, and coaming plate is set around the bank; In the appropriate location, bank feeder is set, flase floor, the attachment weld of ring baffle and waterproof steel plate are laid in the groove top.
The greasy dirt that the present invention produces in the time of can be smoothly to workover treatment carries out water conservancy diversion and collection, and has reduced the risk of construction operation.
1. the up-small and down-big form of structure of trumpet type sleeve guarantees that greasy dirt can flow down smoothly along its outer wall, simultaneously greasy dirt in the drippage position of waterproof steel plate away from the slit between waterproof casing and the steel plate.
2. the trumpet type upper cartridge is the cylinder of one section parcel waterproof casing, and rubber pad is set between the two, can guarantee the sealing tightness of the two.
3. the trumpet type sleeve is two symmetrical half-watts in the plane, is stuck in after the waterproof casing, with bolt two half-watts is coupled together again.Be provided with from top to bottom rubber pad between the bolt junction plate of two half-watts, guaranteed sealing and the tightness of two half-watts.
4. need not when the trumpet type sleeve is installed at the scene to carry out weld job, avoided in the waterproof casing very big risk that weld job produces of directly getting angry.Therefore, to the platform of being on active service, carry out on-the-spot installation exercise in the situation that can not stop production in the oil field.
5. the trumpet type sleeve is removed conveniently, need not directly carry out cutting operation on waterproof casing, the safety when having guaranteed to remove.
6. trumpet type sleeve highly versatile can adopt the trumpet type sleeve of same model under the identical condition of waterproof casing external diameter, can suitably raise or reduce this its position at waterproof casing according to site specific during installation.Therefore, the waterproof casing for certain specification can be mass, and need not to carry out design iterations.
Description of drawings
Fig. 1 is organigram of the present invention;
Fig. 2 is A-A sectional view of the present invention.
The specific embodiment
1. the laying of waterproof steel plate 9.At first remove the former flase floor that is laid on the platform well mouth district, then spread the steel plate of suitable dimension and be spliced into one with welding.Weld coaming plate 10 around welding ring baffle and bank around the waterproof casing 7, the two highly is 100～200mm.At the bank correct position greasy dirt feeder 11 is set, feeder 11 very useful flase floors 12 cover, and guarantee that greasy dirt can flow in the feeder 11 smoothly, and have guaranteed operating personnel's safety and avoided other article to fall into feeder 11.
2. the making of trumpet type sleeve.2 minutes two symmetrical half-watt roll-formings of bottom cone 1 and top cylindrical shell, the inboard nature groove that forms in bottom cone 1 and top cylindrical shell 2 junctions, therefore weld by opening single groove the inboard.Owing between top cylindrical shell 2 and the waterproof casing 7 rubber pad 4 that a layer thickness is about 6mm is set, can avoid the projection of weld seam affect top cylindrical shell 2 and waterproof casing 7 between compactness.Consider the compressibilty of rubber pad 4 and the making tolerance of steel member, the large 3～4mm of comparable waterproof casing 7 external diameters of top cylindrical shell 2 internal diameters simultaneously, keeps the spacing of 3～4mm between bolt 3 junction plates of two half-watt seam crossings.Between bolt 3 junction plates and the cone/cylindrical shell, connect with fillet weld in its outside, junction.The length of bolt junction plate equates that with cylindrical shell/cone length height can satisfy the bolt aperture and get final product.Because this sleeve is not subjected to other external force, so bolt 3 diameters are get final product about 16mm, accordingly the large 1～3mm of bolt aperture ratio bolt 3 nominal diameters.The junction plate height is can satisfy the requirement of bolt aperture about 60mm.Because bolt 3 junction plate height are less, and the lateral support gusset need be set between cylindrical shell/cone.
3. install at the sea of trumpet type sleeve.According to site specific, can adjust the installation site of trumpet type sleeve.Be the attachment weld of waterproof casing 7 such as initial predetermined installation site, can be up or down adjust its position.After bolt 3 tightened, utilize the frictional force between trumpet type sleeve and the waterproof casing 7 can be fixed on assigned address.Because the installation of trumpet type sleeve need not carried out weld job, the aid and the equipment that therefore need are few, and risk is low, and erection procedure is simple, carry out under the condition that can not stop production in the oil field.
4. the dismounting of trumpet type sleeve.As according to the actual requirements, need to remove the trumpet type sleeve, then can carry out easily operation.After bolt 3 unloaded, the frictional force between trumpet type sleeve and the waterproof casing 7 can be eliminated, and removed the trumpet type sleeve under the condition that can not stop production in the oil field.
