Abstract
The present invention provides a kind of methods of acceleration magnesium alloy completion tool dissolution, it is related to completion tool field, by being installed with inert metal material on magnesium alloy completion tool, in the well liquid medium that conductive ion is contained in underground, electrochemical reaction occurs for inert metal material and magnesium alloy, so as to effectively control the dissolution for accelerating magnesium alloy completion tool.
Description
Technical field
The present invention relates to completion tool field more particularly to a kind of methods for accelerating the dissolution of magnesium alloy completion tool.
Background technique
Since the intensity of magnesium alloy is big and light weight, so completion tool has gradually adopted magnesium alloy to replace aluminium alloy
Production, completion tool generally use following steps when in use: complete first section pressure break, assembling perforation tool and solvable bridge plug, general
Tool after assembling is packed into lubricator, tripping in perforation tool and solvable bridge plug, swings one's arm after the positioning of solvable bridge plug, utilizes perforation work
Tool completes the ball seat that multi-stage perforator, well head put into solvable ball, solvable ball is pumped to solvable bridge plug, casing injection mode is pressed
It splits, dissolved to completion tool, realize that oil/gas well is fuel-displaced.
Existing completion tool gradually uses solvable magnesium alloy, but solvable magnesium alloy is expensive, and solvable magnesium closes
Gold course of dissolution be difficult to effectively control, due to magnesium alloy completion tool in place after, there are also the working procedures such as perforation, pressure break, institutes
To require magnesium alloy completion tool to slow down dissolution as far as possible at this time, the failure of the processes such as pressure break otherwise will will cause, to works such as pressure breaks
After the completion of sequence, then magnesium alloy completion tool is required to dissolve as early as possible, thus it is smoothly efficiently fuel-displaced, in order to guarantee the smooth of pressure break process
It carries out, so the solution rate of magnesium alloy completion tool is slow, but seriously affects the speed of subsequent construction, therefore how
Control accelerates the dissolution of magnesium alloy completion tool and effectively reduces cost to become those skilled in the art's urgent problem to be solved.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, a kind of acceleration magnesium alloy is provided
The method of completion tool dissolution.
The present invention is to be achieved by the following technical programs: a method of accelerating the dissolution of magnesium alloy completion tool, it is complete
Well tool uses magnesium alloy, is installed with inert metal material on magnesium alloy completion tool.
According to the above technical scheme, it is preferable that magnesium alloy completion tool surface forms inert metal material using packing technology
Expect wrapping layer.
According to the above technical scheme, it is preferable that inert material wrapping layer outer surface is painted with sealing wax.
According to the above technical scheme, it is preferable that magnesium alloy completion tool surface opens up fluted, and inertia is installed in groove
Metal block.
According to the above technical scheme, it is preferable that inert metal block outer wall is painted with sealing wax.
According to the above technical scheme, it is preferable that inert metal material using one of copper, iron, nickel, zinc and chromium or
Mixing material.
The beneficial effects of the present invention are: the present invention is using conventional magnesium alloy materials, advantage be it is cheap, convenient for industrialization
Production, trade mark multiplicity and quality are stablized, once but disadvantage inert metal wrapping layer falls off or embedded with metal block is fallen, magnesium
The rate of dissolution of alloy can reduce, and the present invention on magnesium alloy completion tool by being installed with inert metal material, in underground height
In the environment of warm high pressure, inert metal material is contacted with conventional Mg alloy surface, by electrochemical reaction, completes the molten of magnesium alloy
Solution can efficiently replace solvable magnesium alloy, and realization reduces cost, and can effectively control and accelerate the molten of magnesium alloy completion tool
Solution.
Specific embodiment
