Contain in polymer drilling fluid as polyacrylamide, guanidine that glue, hydroxyethyl cellulose, sodium carboxymethylcellulose are contour
Molecularly Imprinted Polymer, these polymer to be more likely formed mud cake in stratum, stratum are damaged.Therefore, it is given birth in oil well
Before production, the polymer degradation in mud cake is needed to fall.The degradation of polymer will use the chemical agent with oxidisability in mud cake.
Oxidisability chemical agent in injection well before need to its feasibility carry out laboratory experiment evaluation.At present often using glass container into
Row evaluation experimental, but glass container poor sealing, can not be pressure-resistant, it is impossible to which simulating underground has the situation of pressure, and baking oven
More than after certain temperature, glass container is easy to burst temperature, leads to not be tested, reaction solution even corrodes baking oven.
Utility model content
The purpose of utility model is provided and is polymerize in a kind of heat resisting and pressure resisting drilling fluid aiming at problem of the existing technology
Object degrades evaluation experimental device to solve the problems, such as to encounter in existing experiment.

Courage 3, wherein, 2 bottom of column pressure resistant vessel setting bottom cover 1, top are equipped with the container cover 6 being connect with column pressure resistant vessel 2, container
Lid 6 is axially arranged with the plunger 8 of thread fitting, and 8 bottom of plunger is formed with the gland 5 being arranged at column pressure resistant vessel upper opening
Extrusion fit；Anticorrosive inner bag 3 is arranged between the bottom cover 1 of column pressure resistant vessel 2 and gland 5, and anticorrosive inner bag 3 is with upper cover 4
The cylindrical barrel body of cooperation is sealed, outer diameter is less than 2 internal diameter of column pressure resistant vessel.
Said program further comprises：
2 bottom of column pressure resistant vessel is made up of mating with bottom cover 1 through-hole and boss；The top of plunger 8, which is equipped with, to be added
Power bar 7.
Digital coding is equipped in column pressure resistant vessel 2 and 6 outer surface of container cover, anticorrosive inner bag material is polytetrafluoroethylene (PTFE),
Other component materials are all stainless steel.
Utility model effect:

It is single rationally, using simplicity, the features such as corrosion resistance is good, heatproof is high, compression resistance is big.
Description of the drawings：
Attached drawing 1 is a kind of example structure figure of the utility model.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Polymer degradation evaluation experimental device includes bottom cover 1, column pressure-bearing in the heat resisting and pressure resisting drilling fluid of the utility model
Container 2, anticorrosive inner bag 3, upper cover 4, gland 5, container cover 6, plunger 8 etc..
The opening that 2 bottom of column pressure resistant vessel has with bottom is concentric circles, bottom cover 1 are to have certain thickness round plate,
Diameter is more smaller than the diameter of column pressure resistant vessel 2, can be moved freely in column pressure resistant vessel 2, there are protrusion, projection portion in centre
It is concentric circles with round plate, projection portion can pass through the opening of 2 bottom of column pressure resistant vessel but height is no more than bottom；In anti-corrosion
Courage 3 is cylindric pressure resistant vessel, and the upper cover 4 of same diameter arranged at top, and the diameter of anticorrosive inner bag 3 is than the diameter of column pressure resistant vessel 2
It is smaller, it can be moved freely in column pressure resistant vessel 2；Gland 5 is pressed in above anticorrosive inner bag 3；Column pressure resistant vessel 2 it is suitable for reading
There is screw thread in outside, and the medial surface of container cover 6 has screw thread, and by being rotated around screw thread, container cover 6 can cover tightly column pressure resistant vessel 2；
There is opening among container cover 6, opening has screw thread, and 8 lower outside of plunger has screw thread, and horizontal bore, extension bar are arranged at 8 top of plunger
7 pass through the horizontal bore on plunger 8；To beat at steel seal at column pressure resistant vessel 2 and the side outer wall 9 of container cover 6, beaten at this
Upper identical number.In addition to anticorrosive inner bag material is polytetrafluoroethylene (PTFE), other component materials are all stainless steel.
When being tested using the device, by the protrusion of bottom cover 1 to the bottom for transferring to column pressure resistant vessel 2, by anticorrosive inner bag 3
It cleans, add in reactant and covers lid 4, gland 5 is pressed in above anticorrosive inner bag 3, container cover 6 is screwed, column is covered and holds
Pressure vessel 2 is screwed plunger 8 by rotating extension bar 7, and 3 upper cover 4 of anticorrosive inner bag covers tightly anticorrosive inner bag 3.Then, it will entirely fill
It is placed in the baking oven of required temperature and heats, the reactant allowed in anticorrosive inner bag 3 reacts at a certain temperature.
After reaction, whole device is taken out from baking oven, when confirming that temperature is cooled to room temperature in anticorrosive inner bag 3, first
8 turn-knob of plunger is unclamped pressure release with extension bar 7, then opens container cover 6, gland 5 is taken out and withstands bottom cover 1 with extension bar 7, it will
Anticorrosive inner bag 3 ejects upwards, and anticorrosive inner bag 3 is taken out from column pressure resistant vessel 2, removes after reaction can be poured out after lid 4
Raffinate judges response situation.
It finally cleans each component and dries, steel parts will go up lubricating oil, in order to avoid corrosion, in case using again next time.
