Description
Technical field
The invention belongs to the innovation of waterproof casing offshore installation method in the offshore oil engineering.
Background technology
The work of following waterproof casing belongs to bores preceding preparation, and purpose is insulating sea water, control drilling tool direction and provides mud circulation to return the passage of platform.Traditional waterproof casing offshore installation method is squeezed into method and is pierced method.The method of squeezing into is when fixed platform is dug a well, and after jacket installs and fixes, presses cluster well design well location, one by one waterproof casing is squeezed into well location by pile driver, is driven into the degree of depth and is not less than 40m.The method of piercing is to utilize drilling equipment on floating type or movable offshore boring island, and the well of subdrilling is descended waterproof casing then, grouting well cementation at last.As seen, traditional waterproof casing mounting method all needs Large-Scale Equipment, and therefore, marine mounting cost is high.For the situation that increases the minority well at existing platform facility, traditional waterproof casing mounting method is particularly uneconomical, the more important thing is that the method for piercing still squeezes into method and all have intrinsic defective, the defective of squeezing into method is to cause the platform vibration, influences ordinary production; The defective that pierces method is borehole wall slump problem.
Summary of the invention
Especially pierce the defective that method exists for fear of traditional waterproof casing mounting method, simultaneously also for reducing marine mounting cost, the present invention propose at the newly-increased minority well situation of existing platform facility a kind of waterproof casing mounting method---immersed tube pierces method.Immersed tube pierces method and pierces in reservation on the basis of method friction advantage, and the rig drill bit is installed in bottom, waterproof casing bottom, and the waterproof casing that hangs is followed drill bit and pierced and sink in the soil.Avoid holing borehole wall slump thereby reached, reduce the purpose of mounting cost again.
The scheme that the present invention solves its technical problem is that waterproof casing is hung into mud by platform brill (repairing) well machine hook, the rig drill bit that is positioned at bottom, the waterproof casing bottom boring of breaking ground, bore diameter is slightly larger than the waterproof casing external diameter, and waterproof casing inserts in the boring, up to design attitude with rig.According to this invention, the concrete use of this method comprises rig is installed on bottom, waterproof casing bottom; Rig is connected with power station on the platform by the power hose bundle in the waterproof casing; Waterproof casing is hung on platform and bores on the hook of (repairing) well machine and slowly transfer; Realize the handling and the power hose bundle folding and unfolding of drilling tool by placing cable winch on the platform and hose winch; The rig drill bit dashes the mode that combines with power auger strand and waterpower spray and bores native pore-forming, and the aperture is greater than the waterproof casing diameter, and waterproof casing creeps into drill bit and inserts in the boring.
Be described further below in conjunction with drawings and Examples.
