Description
Technical field
The utility model belongs to oil and gas development simulator design field, and in particular to a kind of fill out sand tube convenient for sand removal.
Background technology
Before rock core displacement test starts, according to the needs of simulation core, the sand grains in fill out sand tube need to be compacted.
After rock core displacement test, to recycle fill out sand tube, the column sand body in fill out sand tube need to be cleaned out.Since sand body is solid simultaneously
It squeezes and is attached on back-up sand inside pipe wall, removing is more difficult, and generally use impact drill combines the mode for removing sand body with long hand shovel.But
That impact drill desanding is primarily adapted for use in the higher sand body of compacting intensity, for longer fill out sand tube, conventional bit can not touch compared with
Deep sand body, and using when drill bit have strong contact with sandpipe inner wall and damage tube chamber, the sand body higher to stickiness is imitated
Fruit is bad；Long hand shovel desanding digs ineffective and easily damages the edge of shovel for the higher sand body shovel of sand body compacting intensity, for compared with
Long fill out sand tube, because the sand body that body is heavy and shovel is dug is extruded in baggermulde, almost shovel is required for removing baggermulde after digging each time,
Laborious time-consuming, work efficiency is very low, and the fill out sand tube recycling cycle is longer, if for a long time, repeatedly shovel, which is dug, easily makes lumen wall
It is damaged, so as to waste of resource, also improves cost.
Authorization Notice No. is that the utility model patent of CN203515571U discloses a kind of improved high temperature and pressure fill out sand tube
Experimental provision, including a tube body and two end cap, the both ends of tube body are respectively equipped with a ring ear, and two end cap corresponds to lid and closes in two ring ears
Place, and fixation is bolted respectively；The lateral surface of ring ear is equipped with circular boop, and the port of circular boop and tube body is in being arranged concentrically, circle
A copper washer is arranged on hoop, circular boop is corresponded on the side of end cap equipped with a bulge loop, the shape of bulge loop and the shape phase of circular boop
Matching, circular boop correspondence are embedded in bulge loop, and the inner peripheral surface of outer circumferential surface and bulge loop is mutually closely connected, is embedded strainer and close in circular boop successively
Seal washer, end face and the copper washer of bulge loop abut against.At work, the joint of end cap and ring ear has the utility model patent
There is good leakproofness, it can be ensured that experiment is normally smoothed out, but still can not easily be disposed inside fill out sand tube
Sand body.
