Technical field
The present invention relates to the high hole rock Seepage Experiment technical field of meter level, the specially high hole rock Seepage Experiment of nanoscale is close
Sealing.
Background technique
Seepage Experiment is that the important research means in Petroleum finance are usually prepared in traditional Seepage Experiment
Centimetre to decimeter grade regular geometric shapes rock sample (as cylindrical), sealing film is pasted to rock sample side, at unencapsulated both ends
Injection and outflow fluid.However, being studied in practice some, generally require to meter level, the rock of even more large scale is seeped
Stream experiment, at this moment, Fluid pressure added by sample interior is higher, and experimental period is longer, and sealing area is bigger, conventional seals at this moment
No matter film from the strength of materials, sealing joint degree, whole durability degree and scantling etc. all suffers from great challenge, In
It is inconvenient in practical operation, test failure rate is high.
In this regard, the glue class using high strength after curing carries out one-piece casting to rock sample, formed in sample surfaces close
Adhesive layer then can solve this problem, such as conventional epoxies class glue.In general, conventional epoxies class glue is pressing one
After certainty ratio and process are prepared, the often process of experience " first thinning, then retrogradation ", still, for some holes, molten
Rock that hole, crack are developed very much (as the carbonate rock after weathering or corrosion occurs), hole, hole, when being sewed with most
It is high several centimeters reachable, if pouring above-mentioned traditional glue, it can be penetrated into after thinning in the hole, hole, seam of rock sample, change rock
The porosity and permeability of script, leads to the failure of an experiment.
Summary of the invention
The purpose of the present invention is to provide the high hole rock Seepage Experiment sealants of nanoscale, to solve in above-mentioned background technique
It is proposed in traditional Seepage Experiment, usually prepare centimetre to the regular geometric shapes rock sample of decimeter grade (as cylindrical), it is right
Rock sample side patch sealing film injects and flows out fluid at unencapsulated both ends.However, being studied in practice some, often need
Seepage Experiment is carried out to meter level, the even more rock of large scale, at this moment, Fluid pressure added by sample interior is higher, experiment week
Phase is longer, and sealing area is bigger, conventional seals film at this moment, no matter from the strength of materials, sealing joint degree, whole durability degree and
Scantling etc. all suffers from great challenge, is inconvenient in actual operation, the high problem of test failure rate.
