Abstract
The invention relates to a device for preventing oil leakage of a shallow sea drilling oil field. The device is characterized in that a conical oil collecting hopper is arranged at a drilling opening; the drilling opening is covered by the conical oil collecting hopper by taking the drilling opening as center; in a working process, when the drilling opening is subjected to oil leakage, the leaking oil is collected into an oil collecting drum; the leaking oil is pumped into an oil storage tank by only starting an oil pump. In such a manner, the happening of offshore well oil leakage accident can be prevented and the ocean water quality and ocean environment can be protected, so that the device for preventing oil leakage of the shallow sea drilling oil field provided by the invention is necessary and required.
Description
Technical field
The present invention relates to a kind of offshore oilfield device, specifically one kind prevent shallow-water oilfield drilling well mouth oil leaking device.
Background technology
Explored offshore oil reserves take up an area the 25.2% of ball petroleum total reserve in the world, and gas reserves accounts for 26.1%.
Offshore oil reserves have in the range of 55% ~ 70% continental shelf in the depth of water less than 200 meters.1897, the U.S. was at first in Jia Lifuni
First offshore field got by Ya Zhou West Coast timber trestle bridge.There are nearly thousand offshore drilling platformses in the world at present, throughout
The each ocean in the world.The Gulf of Mexico is the most active greater coasting area of drilling well in the world, current operation just have 19000 multiple wells.?
More than 120, the offshore drilling ship of Bay area operation.Louisiana, United States bank has nearly hundred, rig.Norway, Brazil etc.
The offshore oil drilling of state is very prosperous, has the tens of seats of drilling platforms, and also a large amount of supply vessel, helicopters are in off-shore operation.20
During the eighties in century, the country of offshore exploration has exceeded 100, and marine oil-producing country is more than 40.In nearly 20 years, Crude oil from CNOOC yield
Proportion increased 1 times in the total oil production in the world.Offshore field oil accident more takes place frequently, and oil leak can bring water pollution
And ecocatastrophe, and cause the related industries such as fishery, tourist industry impaired.So invention one kind prevents shallow-water oilfield drilling well mouth oil leak
Device is the demand that must very cut.
Content of the invention
It is an object of the invention to provide one kind prevents shallow-water oilfield drilling well mouth oil leaking device, to solve above-mentioned background technology
Problem.
For achieving the above object, the technical solution adopted in the present invention is as follows：
One kind prevents shallow-water oilfield drilling well mouth oil leaking device, it is characterized in that arranging a conical oil-collection funnel in drilling well mouth, described
Conical oil-collection funnel centered on drilling well mouth, and drilling well mouth, described cone are lived as bottom with the big mouth of conical oil-collection funnel
Shape top osculum is provided with one and receives oily cylinder, and described receipts oil cylinder arranges super above tide, if described receipts oil cylinder inwall is provided with
Dry oil well pump, the described power supply control circuit of oil well pump is connected with the power supply control circuit of drilling platforms, and described takes out
Oil pump is connected with oil storage tank by petroleum pipeline, and described oil storage tank is arranged at the one end above drilling platforms.
Beneficial effects of the present invention:The one kind prevents shallow-water oilfield drilling well mouth oil leaking device, it is characterized in that by drilling well
Mouthful a conical oil-collection funnel is set, described conical oil-collection funnel covers drilling well mouth centered on drilling well mouth, at work when
During drilling well mouth oil leak, receiving oily cylinder can be leakage oil collection in receiving in oily cylinder, as long as starting oil well pump oil leak is pumped to oil storage tank.This
Sample it is prevented that the generation of offshore field oil accident, protects ocean water quality and marine environment, so invention one kind prevent shallow
Extra large oil field drilling well head oil leaking device is the demand that must very cut.
Description of the drawings
Fig. 1 is a kind of structural representation for preventing shallow-water oilfield drilling well mouth oil leaking device of the present invention.
In figure：
1- drilling platforms, 2- drilling well mouth, 3- cone oil-collection funnel, 4- receives oily cylinder, 5- oil well pump, 6- petroleum pipeline, 7- oil storage tank.
Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
One kind prevents shallow-water oilfield drilling well mouth oil leaking device, it is characterized in that arranging a conical oil-collection funnel in drilling well mouth 2
3, described conical oil-collection funnel 3 is centered on drilling well mouth 2, and lives drilling well mouth 2 with the big mouth of conical oil-collection funnel 3 as bottom,
Described taper top osculum is provided with one and receives oily cylinder 4, and described receipts oil cylinder 4 arranges super above tide, the oily cylinder 4 of described receipts
Inwall is provided with several oil well pumps 5, the power supply control circuit of described oil well pump 5 and the power supply control circuit of drilling platforms 1
It is connected, described oil well pump 5 is connected with oil storage tank 7 by petroleum pipeline 6, and described oil storage tank 7 is arranged above drilling platforms 1
One end.
Above-mentioned legend is only the exemplary embodiments of the present invention, is not limited to the present invention, all spirit in the present invention and
Any modification, equivalent and improvement for being made within principle etc., should be included within the scope of the present invention.
