Abstract
The utility model relates to equipment used for mooring an oil storage tanker and other devices in the development of an offshore oilfield. Two groups of mooring equipment are arranged on the utility model, each group of mooring equipment is formed by the mutual connection of an underwater mooring buoy, an anchor and connecting pieces, one end of a mooring cable is connected with the underwater mooring buoy, the other end of the mooring cable is connected with an oil storage tanker or other devices, and thus, double point mooring equipment with the underwater mooring buoy is formed. The utility model has the advantages of simple structure, easy transport, less investment, obvious effect, less wave disturbance and better resistance to wave and wind; besides, the fabrication, the installation and the application process of the utility model are obviously simplified, and the utility model can be reusable.
Description
The utility model relates in the offshore oil field development, a kind of equipment of mooring oil storage wheel and other device.
In marine petroleum development, the size of oilfield reserve is main to be relied on prospect pit is carried out formation testing, obtained the oil reservoir data and determine, and the length of formation testing time directly influences the accuracy of oil reservoir data, and then influences the scale of investment of whole engineering.In formation testing in the past, because the crude oil of output stores nowhere, can only on drilling ship, carry out several hours short test, the data that obtain so often can not accurately reflect the reserves and the production capacity in oil field.Some oil field is after extensive the operation, and initial situation is good, but the time longly just can not get stable output, thereby caused huge waste, address this problem, just need a cover can prolong the mooring facilities of testing.
Oil storage wheel or other Fuel Tanking Unit adopt single buoy mooring system usually in the off-shore oil field engineering at present, as fixing mooring tower structure, Fuel Tanking Unit is from mooring structure etc., they all carry out mooring by mooring fast to oil storage wheel or Fuel Tanking Unit, and the characteristics of this system are that the oil storage wheel can be around any comprehensive revolution.Be subjected to the restriction of its version and mooring mode, no matter which kind of structure crude oil all must just can be transported on oil storage wheel or the Fuel Tanking Unit by swivel joint, and swivel joint is external a kind of patented product, needs special import; Have in addition for to match with this swivel joint and mooring structure, used oil storage wheel also should be that existing common oil tanker or Fuel Tanking Unit are at all can't be direct coupled with this single buoy mooring system through the special transformation of the way or the special ship of building.In view of the foregoing, adopt single buoy mooring system to carry out development of the field, exist construction investment huge, complex structure, the cycle is long, and drawbacks such as cost height are also applicable to good in economic efficiency large-scale high yield oil field, and middle-size and small-size oil field then is difficult to bear, implement.
The purpose of this utility model is to avoid weak point of the prior art, and the oil storage wheel mooring gear of a kind of simple structure, maneuverability, small investment is provided.
Can take following technical scheme to realize purpose.Two groups of berthing accommodations are set, are respectively applied for bow, the stern of oil storage wheel or Fuel Tanking Unit, every group of berthing accommodation is all by mooring buoy and anchor under water, be interconnected to constitute with attaching parts; Mooring fast one end is connected with mooring buoy under water, and the other end is connected with oil storage wheel or Fuel Tanking Unit, makes 2 mooring gears of sub-surface buoy.
In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.
Fig. 1 is a kind of structural representation of one group of berthing accommodation in the two-point form mooring gear.
Fig. 2 is the another kind of structural representation of one group of berthing accommodation in the two-point form mooring gear.
The two-point form mooring gear adopts two groups of berthing accommodations, at bow, stern two places oil storage wheel or Fuel Tanking Unit is carried out mooring respectively.Berthing accommodation is all by mooring buoy 2 and anchor 1 are connected to form with attaching parts 3 under water.Anchor in the berthing accommodation, the quantity, size, shape etc. of mooring buoy all can be selected according to using needs and environmental conditions to take the circumstances into consideration under water.Be that berthing accommodation can be a mooring buoy 2 and the underwater structure that anchor 1 is connected to form with attaching parts 3 under water; Can be two or more mooring buoys under water 2 and the underwater structure that anchor 1 is connected to form with attaching parts 3; Can be a mooring buoy 2 and the underwater structure that two or more anchors 1 are connected to form with attaching parts 3 under water, can also be the underwater structure that two or more mooring buoys under water 2 and two or more anchors 1 are interconnected to constitute with attaching parts 3.
Anchor 1 can adopt gravity type boat davit, the anchor of grip formula and other form, and it should have enough grips, to resist the buoyancy of mooring buoy 2 and the mooring force of oil storage wheel or Fuel Tanking Unit under water; Mooring buoy is in below the water surface under water, and it links to each other with anchor by attaching parts.Attaching parts 3 can adopt various ways such as chain, cable, bar to constitute.One end of mooring fast links to each other with cooresponding mooring buoy under water during use, and the other end links to each other with the bow or the stern of oil storage wheel or Fuel Tanking Unit, and the buoyancy of mooring buoy makes whole mooring gear have certain restoring force under water, thereby forms a better elastic system.Oil storage wheel or Fuel Tanking Unit reach the afloat purpose of mooring by bow, 2 of sterns like this, and the crude oil of exploiting out just can be transported on common oil storage wheel or the Fuel Tanking Unit from production platform by oil hose, and need not swivel joint.
Routinely, the two ends of mooring fast all should be hinged with the friction chain, to guarantee the reliability of work, increase the service life.
Sub-surface buoy is the major equipment of whole device, can with attaching parts sub-surface buoy and anchor be linked together on land earlier during installation, throws to put to marine designated area to get final product.
The relative prior art of this mooring gear has following advantage:
1, general structure is simple and easy, obviously letter of the technological process of making, install, using Change, can reuse, easy to operate. Resettlement is easy, small investment, instant effect.
2, be Two Points Underwater Buoy Mooring System, it is the little sinking of wave agitation Floating drum elasticity anchoring system has and stands preferably stormy waves; For prolonging test, carry Effect and the quality of high test, for reasonably determining the oil development scheme, assessment is final Recovery ratio provides infallible condition.
