Abstract
The invention discloses an emergency rescuing device for incontrollable blowout in petroleum drilling. The emergency rescuing device for the incontrollable blowout comprises a blowout-proof device assemblies which are open but can be hydraulically controlled by a soft pipeline, a shell which is heavy enough to be stable and has an enough high bearing capability, throttling valves which are open but can be hydraulically controlled over the opening degree of the valve through a soft pipeline till the valve is completely closed, and fixing and sealing devices. The emergency rescuing device for the incontrollable blowout overcomes the defects in the prior art; an emergency rescuing device used after the incontrollable blowout in the drilling process is provided so as to reduce the loss to the minimum extent and quickly and timely control the blowout after the incontrollable blowout; and the emergency rescuing device for the incontrollable blowout is applicable to emergency rescuing for the blowout in a deep drilling process.
Description
Technical field:
The present invention relates to the blowout out of control device of speedily carrying out rescue work, be meant a kind of device of speedily carrying out rescue work behind the blowout out of control of in deepwater drilling, being used for especially, belong to petroleum operations device field.
Background technology:
After blowout out of control is meant that blowout takes place, can't controls well head and the phenomenon of uncontrolled flow occur with conventional method.Blowout out of control is the catastrophic failure that character is serious in the drilling engineering, loss is huge, and its harm is huge.Upset comprehensive operate as normal order, the influence overall situation is produced; Make drilling failure complicated; Blowout out of control very easily causes fire and ground subsidence, and huge numbers of families' life security causes environment pollution around the influence, influences irrigation and water conservancy, fishing ground, pasture, forest farm construction.Injury oil-gas Layer, destruction underground oil and gas resource; Cause fatal crass and oil gas well to scrap, bring enormous economic loss.After well control is out of control mainly is according to the well head situation, formulates emergency measure, selects the correct device of speedily carrying out rescue work.
Emergency measure after the present drilling well generation blowout mainly is the blowout out of control to the land.
The drillng operation blowout supporting technology of speedily carrying out rescue work is exactly to different blowout situation, uses different emergency techniques, and the supporting spraying equipment of robbing is accordingly subdued blowout fast and effectively, reaches the purpose of safety in production.Drillng operation blowout emergency technique is more single at present, and blowout control device is mainly speedily carried out rescue work with HK-3, HK-4, double disc blowout preventer, cock and all kinds of blowout control device.
The device of more than speedily carrying out rescue work all need or be removed former wellhead assembly to the well head trimming.Remove at present old wellhead assembly, can adopt that the winch pressurization is set upright, guiding, long-armed crane integral body hang.New wellhead assembly is installed, can be adopted integral hoisting or bulk-breaking spiral-lock method to carry out.
The design of HK-3 type oil gas well blowout control device is after the blowout of oil gas well takes place, can within a short period of time installing wellhead blowout preventer and to guarantee that the well head operating personnel person and construction safety are the basis.Its operating principle is; The lower slips of device is fixed on the casing nipple; Be fixed in well head one side with two reducing bearing pin handle assembly axis bodies; Push blowout preventer the axial location of oil well casing to through Upper shaft sleeve around the rotation of axis body, through adjustment leading screw fine setting eccentric throw blowout preventer latus rectum center is overlapped with casing axis then.Through the center leading screw blowout preventer is pressed on the former wellhead flange dish, gets final product safe installation well head bolt, fastening well head, close blowout preventer, accomplish emergency work construction.For guaranteeing the construction safety in the whole process of speedily carrying out rescue work, do not adopt any equipment dynamic in the device design process, to avoid in whole construction course, causing fire.
Summary of the invention:
The objective of the invention is to overcome the shortcoming of prior art, the device of speedily carrying out rescue work after the deepwater drilling blowout out of control is provided.Purpose is after the blowout out of control loss to be dropped to minimum, controls blowout rapidly in time.This device is applicable to that the deepwater drilling well control speedily carries out rescue work.
Operating principle of the present invention
This device is as shown in Figure 1: 11,12 are preventer combination, open wide, but can adopt the soft pipeline control of surging; 4 is housing, has enough weight and is convenient to stablize, and have enough bearing capacities; 2,3,8,9 is choke valve, opens wide, but can adopt soft pipeline to surge the by-pass valve control aperture until closing extremely; 5,6 is the fixing seal system,
This device can fixedly be sealed on the former wellhead assembly, and the preventer that lost efficacy is under water firmly covered; Be lowered in the process, choke valve and preventer open wide, and reduce the impact force of the oil gas of blowout to new equipment; Fixing back choke valve and preventer can carry out hydraulic control through platform soft pipeline etc. and close.
This blowout out of control being lowered to of well control device of speedily carrying out rescue work can be lowered to through drilling rod.At first, near the seabed, this process preventer, choke valve and bypass valve are opened under the novel well control device, to reduce the blowout impact force.When this device safety is seated in well head, make it concentric with former wellhead assembly.The bottom chuck is fixed on the former wellhead assembly.Squeeze into sealing substances such as cement paste subsequently through bypass valve, this device is cemented in well head.Then, preventer is closed in examination, and choke valve is closed in examination, selects different processing schemes according to condition of different.
This device is fixedly sealed on the former well head, and this is a very important step, also is a big difficult point.For fixing seal well, specialized designs chuck (as among Fig. 1 6) and bypass valve (as among Fig. 1 5).This device is lowered to the seabed, and chuck can close rapidly extremely, is fixed on the former wellhead assembly.Then, squeezing into sealing substances such as cement paste through bypass valve installs and fixes brand-new well head well control device on the former well head.
The present invention compares with background technology, has the following advantages:
1, preventer of this device and choke valve all are existing elements, do not need design separately and making.
2, this device is a conceptual design, can be according to the size of former wellhead assembly, design the different blowout out of control device of speedily carrying out rescue work.
Description of drawings:
Fig. 1 is the blowout device sketch map of speedily carrying out rescue work
Fig. 2 well head sketch map of can pressure-bearing speedily carrying out rescue work
Fig. 3 well head can not pressure-bearing running against pressure bar sketch map
The specific embodiment:
(1) former well head can bear shut-in pressure situation kill-job scheme
Former well head can bear under the shut-in pressure situation, has three schemes available:
First kind of scheme closed preventer, closes choke valve then, and be thoroughly that Jing Guan is dead, prevents the leakage of crude oil;
Second kind of scheme through this device snubbing drilling rod, squeezed into the direct kill-job of well killing fluid, rebulids circulation, makes this well controlled;
The third scheme after blowout is controlled, is installed production tree on new well control device, recover the oil, and makes to face the well of scrapping and radiate the vigour of youth.
(2) former well head bears part shut-in pressure situation kill-job scheme
Former well head bears under the part shut-in pressure situation, and the kill-job step is following:
During this period, flexible pipe can be installed on choke valve, through flexible pipe oil gas controlledly be drained into drill ship and handle.
