Abstract
The present invention provides a kind of slow-release magnesium alloy completion tool cosolvents, it is related to magnesium alloy completion tool auxiliary reagent field, compare according to parts by weight, including glutinous rice glue, potassium chloride, iron chloride, calcium sulfate, stabilizer and fungicide, by specific preparation process, to realize magnesium alloy completion tool solution rate by slowly to quickly.
Description
Technical field
The present invention relates to magnesium alloy completion tool auxiliary reagent fields more particularly to a kind of slow-release magnesium alloy completion tool to help
The preparation method of solvent.
Background technique
Existing completion tool includes solvable bridge plug and solvable ball, since the intensity of magnesium alloy is big and light weight, institute
Magnesium alloy has been gradually adopted to replace aluminium alloy production with completion tool, solvable bridge plug and solvable ball mostly use greatly when in use
Following steps: first section pressure break, assembling perforation tool and solvable bridge plug are completed, the tool after assembling is packed into lubricator, lower incidence
Hole tool and solvable bridge plug swing one's arm after the positioning of solvable bridge plug, are solvable using perforation tool completion multi-stage perforator, well head investment
Ball, the ball seat that solvable ball is pumped to solvable bridge plug, casing injection mode carry out pressure break, dissolve to solvable ball and solvable bridge plug,
Realize that oil/gas well is fuel-displaced.
The course of dissolution of existing completion tool is difficult to effectively control, due to magnesium alloy completion tool in place after, also penetrate
The working procedures such as hole, pressure break it requires that magnesium alloy slows down dissolution as far as possible at this time, otherwise will will cause the mistake of the processes such as pressure break
It loses, after the completion of the processes such as pressure break, then magnesium alloy completion tool is required to dissolve as early as possible, thus it is smoothly efficiently fuel-displaced, in order to guarantee
Pressure break process is gone on smoothly, so the solution rate of magnesium alloy completion tool is slow, but seriously affects the speed of subsequent construction
Degree, therefore how to make the solution rate of magnesium alloy completion tool by slowly to quickly becoming those skilled in the art urgently
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 sustained release magnesium conjunction is provided
The preparation method of golden completion tool cosolvent, the cosolvent realize magnesium alloy completion tool solution rate by slowly to quickly.
The present invention is to be achieved by the following technical programs: a kind of slow-release magnesium alloy completion tool cosolvent, according to weight
Measure portion rate, including 25-36 parts of glutinous rice glue, 11-20 parts of potassium chloride, 10-20 parts of iron chloride, 30-44 parts of calcium sulfate, stabilizer 1-
5 parts and 1-4 parts of fungicide.
According to the above technical scheme, it is preferable that compare according to parts by weight, including 28-32 parts of glutinous rice glue, potassium chloride 13-17
Part, 13-18 parts of iron chloride, 32-40 parts of calcium sulfate, 1-3 parts of stabilizer and 1-3 parts of fungicide.
According to the above technical scheme, it is preferable that compare according to parts by weight, including 30 parts of glutinous rice glue, 15 parts of potassium chloride, chlorination
15 parts of iron, 36 parts of calcium sulfate, 2 parts of stabilizer and 2 parts of fungicide.
A kind of preparation method of slow-release magnesium alloy completion tool cosolvent, comprising the following steps:
(1) above-mentioned each raw material is weighed according to parts by weight；
(2) stabilizer and fungicide are placed in agitator and mixed solution is mixed evenly into；
(3) glutinous rice glue, potassium chloride, iron chloride and calcium sulfate be ground to powdered；
(4) successively powdered glutinous rice glue, potassium chloride, iron chloride and calcium sulfate are added in mixed solution；
(5) plastic stir rod is driven to stir evenly mixed solution using high speed agitator.
(6) mixed solution is poured into the mold of certain shapes, dries 18-30h in 45-70 DEG C of baking oven.
According to the above technical scheme, it is preferable that step (6) pours into mixed solution in the mold of certain shapes, at 60 DEG C
Baking oven in dry for 24 hours.
The beneficial effects of the present invention are: cosolvent finished product of the invention is by inlaying or technique for sticking and completion tool phase
Connection, and it is pumped to underground with completion tool, in the environment of liquid, cosolvent is slowly dissolved, and discharges effective component, hydrotropy
Iron ion in agent reacts generation iron with magnesium alloy and is attached to Mg alloy surface, and it is anti-that electrochemical corrosion occurs in potassium chloride medium
The dissolution that quickening magnesium alloy completion tool should further be promoted, to realize the solution rate of magnesium alloy completion tool by slow
To quick.
