Abstract
A quantitative core filling device includes a base, a tube seat, a bracket, a stainless steel hammer, a sling, a core barrel, a pulley and a marked handwheel. The core barrel and the bracket which are fixed together are arranged on the base. The top of the bracket is provided with the pulley and the middle part is provided with the marked handwheel. The stainless steel hammer is arranged inside the core barrel. One end of the sling is fixed on the stainless steel hammer and the other end goes around the pulley to be fixed on the marked handwheel. The utility model has high repetitiveness of core permeability, which can be more than 85 percent. The utility model has the advantages of simple structure, small bulk, easy movement, convenient operation and labor saving, which is broadly applied to the indoor lab of oil recovery ratio research.
Description
One, technical field
The utility model relates to petroleum industry and improves recovery ratio indoor physical simulation testing equipment, particularly a kind of quantification rock core device for filling.
Two, background technology
Improve in the recovery ratio simulation laboratory test in oil exploitation, owing to be subjected to the restriction of operability, economy, natural core, Berea core are difficult to obtain, the still mode of artificial back-up sand that the scientific worker generally adopts is made test core, but the rock core that this mode makes exists manually-operated lack of standard, make differing greatly of each rock core filling, can not guarantee the shortcoming or the deficiencies such as comparativity of physical simulation experiment.
Three, summary of the invention
The purpose of this utility model provides a kind of improved quantification rock core device for filling, changes the present situation of existing laboratory core filling poor repeatability.The permeability value repeatability that makes indoors artificial fill rock core improves, and has also effectively improved the indoor physical simulation test efficiency simultaneously, effectively in the shortcoming or the deficiency that overcome or avoid existing in the above-mentioned prior art.
Quantification rock core device for filling described in the utility model, comprise base, base, support, stainless steel hammer, lifting rope, basket, pulley, band scale handwheel, described basket and support are installed on the base, basket and support fix, prop up top of the trellis pulley is installed, the middle part is equipped with band scale handwheel, lays stainless steel hammer in the described basket, described lifting rope one end is fixed on the stainless steel hammer, and the other end is walked around pulley and is fixed on the band scale handwheel.
Wherein, described basket lower end is equipped with pipe cap, and pipe cap is located on the base.Described basket by pipe clamp and bolt on support.The upper end of described stainless steel hammer is fixed by attaching nut and lifting rope.
The utility model has the following advantages compared with prior art:
1, utilize the filling method of machinery, the core permeability repeatability of filling is high, and repeatability can reach more than 85%.
2, matching used small-sized rock core device for filling is simple in structure, mainly hit tight device by basket fastening devices and quartz sand and form, and device itself is less, and mobility is good.
3, matching used small-sized rock core device for filling is simple to operate, laborsaving, easy to operate, in hitting tight the process of quartz sand, only need utilize fixed pulley and band scale handwheel that quartz sand is hit tight device and mention certain altitude release, utilize the gravity of itself quartz sand can be hit tight.
Four, description of drawings
Accompanying drawing is a kind of structural representation of the present utility model.
Five, the specific embodiment
Consult accompanying drawing, a kind of quantification rock core device for filling, comprise base, base, support, stainless steel hammer, lifting rope, basket, pulley, band scale handwheel, basket 9 and support 3 are installed on the base 1, and basket 9 fixes with support 3, and support 3 tops are equipped with pulley 11, the middle part is equipped with band scale handwheel 12, lay stainless steel hammer 6 in the basket 9, lifting rope 7 one ends are fixed on the stainless steel hammer 6, and the other end is walked around pulley 11 and is fixed on the band scale handwheel 12.
During use, permeability is 1.7 μ m
2The placement method of rock core: after basket 9 cleaned oven dry, install the pipe cap 10 of an end after, basket vertically is placed on the basket base 2, pipe cap 10 is buckled well rock core pipe clamp 4 down, tightens set bolt 5.Take by weighing 40g40～60 order quartz sands then, added water than 9: 1 by sand water, standby after stirring evenly.Claim 1860g120～140 order quartz sands, added water than 9: 1 by sand water, standby after stirring evenly.Once insert the moisture quartz sand of 40～60 orders in the basket then, again stainless steel hammer 6 is inserted in the basket, then Φ 3 stainless steel wire slings 7 are fixed on after by pulley 11 on the band scale handwheel 12, rotate handwheel 12, (handwheel 12 edges indicate scale with the mobile straight up 35cm of stainless steel hammer 6, girth is 80cm), freely discharge, so repeat 40 times, behind this EO, again the moisture quartz sand of 120～140 orders is divided every batch to add about 50g and to add in the basket, according to aforesaid operations, every batch hits tight 40 times, tightens pipe cap 10 at last, this basket end-of-fill, the permeability value of filling this basket according to this is at 1.7 ± 0.05 μ m
2Scope in.
Permeability is 0.7 μ m
2The placement method of rock core: after basket 9 cleaned oven dry, install the pipe cap 10 of an end after, basket vertically is placed on the basket base 2, pipe cap 10 is buckled well rock core pipe clamp 4 down, tightens set bolt 5.Take by weighing 60g40～60 order quartz sands then, added water than 9: 1 by sand water, standby after stirring evenly.Claim 2000g180～200 order quartz sands, added water than 8: 1 by sand water, standby after stirring evenly.Once insert the moisture quartz sand of 40～60 orders in the basket then, again stainless steel hammer 6 is inserted in the basket, then Φ 3 stainless steel wire slings 7 are fixed on after by pulley 11 on the band scale handwheel 12, rotate handwheel 12, with the mobile straight up 30cm of stainless steel hammer 6, freely discharge, so repeat 32 times, behind this EO, the more moisture quartz sand of 180～200 orders is divided every batch to add about 50g and to add in the basket, according to aforesaid operations, every batch hits tight 32 times, tighten pipe cap 10 at last, this basket end-of-fill, the permeability value of filling this basket according to this is at 0.7 ± 0.05 μ m
