Description
Technical field
Oil-gas field development field is the utility model is related to, analyzing a kind of used long cores to reservoir core displacement clamps
Equipment.
Background technology
In oil-gas field development field, it is often necessary to which reservoir rock is analyzed.There is a kind of important rock core displacement test,
Long rock core holder can be used.Long rock core holder on the market more or less lacks during use in the presence of some at present
Fall into.Subject matter is that the adjustable extent of long rock core holder is little.The length of experiment long cores is all different every time, and adjustable extent is small
Limit the use of core holding unit.Whole device is installed cumbersome with dismounting.If in addition, experimentation inlet pressure and
Confined pressure control is improper to cause packing element to be worn by pressure leakage or pressure, cause the failure of an experiment, rock core is contaminated.Wherein, one it is critically important
Reason is that short rock core is not compacted.The seal approach design deficiency of clamper.In view of the above-mentioned problems, we pass through to long cores
The structure of clamper redesigns, and solves the defects of existing design.A kind of easily operation, the clamping of safe and reliable long cores are provided
Device.
Utility model content
The purpose of the utility model is to overcome the shortcomings of the existing long rock core holder technology in market, there is provided a kind of easy
Operation, safe and reliable new long rock core holder.
Technical scheme is used by the utility model：
The utility model long rock core holder mainly by clamper cylinder, inner thread sleeve, entrance plug, middle plug,
Export plug, the special disposable plastic packing element in laboratory, screw rod, jump ring, pipeline, sealing bolt composition.Long rock core holder cylinder
Body uses symmetrical integrated design.It is confined pressure hole among cylinder, confined pressure is added to packing element by confined pressure hole.The right is steam vent.Cylinder
Body is locally designed using regular hexagon, convenient installation and fixed cylinder during dismounting clamper.
The installation of clamper.First, by measuring the length of long cores and both ends probe, the length of plastics packing element is determined
Equal to rock core length and probe length sum.Rock core to be measured is fitted into plastics packing element.The entrance of plastics packing element, port of export difference
It is connected by entrance plug with the probe of middle plug front end, probe distal end has O-ring seal, for sealed plastic packing element.Modeling
Material packing element extends further into plug groove, and notch end has sealing ring, secondary seal plastics packing element.Plug outer end is equally positive six
Side shape design.Facilitate equipment installation and dismounting.Then, the internal thread of screw rod one end and entrance plug is coordinated by screw thread fixes,
The screw rod other end passes through the preformed hole of middle plug, tightens nut.Rock core is compacted with this, prevents plastics packing element quilt in experimentation
Pressure is worn.
Next sealing line segments are done.Two root long degree are taken to be equal to the straight pipe-line of clamper barrel lenght, pipeline one end connects
I type sealing bolts are connect, and bolt is fastened on middle plug end face.Secondly by the entrance assembled above plug-plastics packing element-
Middle plug-line construction is put into clamper cylinder.Entrance plug passes through fitted seal circle, inner thread sleeve clips holder
Cartridge inlet port.Then the pipeline other end is coordinated through outlet plug, outlet plug with sealing ring, inner thread sleeve, sealing
Clamper cartridge outlet end.Inner thread sleeve uses anti-skidding design.Finally, the pipeline other end is connected into II type sealing bolts, spiral shell
Bolt coordinates with packing ring, tightens bolt.Clamper cylinder is fully sealed.Jump ring is installed, the dismounting of clamper after convenient experiment.
Clamper opens steam vent after assembling, and hydraulic oil is added from confined pressure hole.Treat that air is drained, hydraulic oil fills annular space,
Seal vents.

Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of new long rock core holder of the utility model, mainly by clamper cylinder
1, inner thread sleeve 2, entrance plug 3, middle plug 4, outlet plug 5, screw rod 6, the special disposable plastic packing element 7 in laboratory,
Confined pressure hole 8, steam vent 9, jump ring 10, II types sealing bolt 11, I type sealing bolt 12-13, pipeline 14, jump ring groove 15, probe
16-17, internal thread 18, pop one's head in groove 19-20, the sealing ring 21-28 of different size, and seal washer 29 forms.Long cores clamp
Device cylinder 1 uses symmetrical integrated design.It is confined pressure hole 8 among cylinder, by confined pressure hole to plastics packing element 7 plus confined pressure.The right
It is steam vent 9.Cylinder 1 is local to be designed using regular hexagon, convenient installation and fixed cylinder during dismounting clamper.The peace of clamper
Dress.First, by measuring the length of long cores and both ends probe 1617, determine that the length of plastics packing element 7 is equal to rock core length
