Description
Technical field
This utility model belongs to oil-gas field development technical field, more particularly, to hydraulic fracturing seam net at a temperature of simulated formation
The laid rule visualization device of proppant.
Background technology
With the development of World Economics, the dependence and demand to oil is increasing, and the yield of conventional oil reservoir and storage are adopted
Than all showing the trend for increasingly reducing, the exploration and development of LOW PERMEABILITY RESERVOIR is supplemented as the energy and is subject to people's attention.And waterpower
Pressure break plays very important effect in the volume increase exploitation of low-permeability oilfield, and the high flow conductivity crack that pressure break is formed not only determines
Volume increase, augmented injection ability after fracture in oil and water wells, and also affect the breakthrough recovery and ultimate recovery of oil reservoir.And
In hydraulic fracturing process, due to the impact of the factors such as fracturing fluid prop-carrying capacity, fracturing fluid leak, proppant is defeated in crack
Send and can have a greatly reduced quality, cause partly the fracture spaces of pressure break there is no proppant pack.As crustal stress is acted on, return in fracturing fluid
After row, the crack without proppant pack closes once more, forms invalid crack, is severely impacted fracturing yield increasing effect.Cause
This, proppant effectively laid situation is carried out studying, predicting be hydraulic fracturing storey increase design key point.
So far, Transport Law research of the Chinese scholars to proppant in pressure-break is concentrated mainly on theoretical derivation
With two aspects of laboratory experiment.However, due to factors all shadows such as the rheological characteristic of liquid, flow velocity, proppant concentration and density
The Transport Law of proppant is rung, therefore, it is relatively difficult by in-house laboratory investigation proppant transport rule.
Experimental provision main at present has：
2005, Yajun Liu have developed the small-sized narrow slit equipment for considering raw sugar wall, high length and width.Using rough
Parallel-plate research shows that, when fracture width is close to proppant diameter, Horizontal Movement speed is remarkably decreased；When the wall in crack is got over
When coarse, the nearly phenomenon of finger of fracturing fluid is more obvious；With low viscosity fracturing fluid displacement high viscosity fracturing fluid, proppant is entered more
Deep Fractures are favourable.
Eissa in 2007 devises a high 0.lm, the small-sized narrow slit model of long 0.2m, wide 3mm, because equipment is less,
Therefore porch does not consider true shaft bottom situation, the only central authorities in end have respectively opened the entrance and exit of a diameter 3mm.Experiment
Using 20 and 30lb/Mgal guar gum, 5lb/Mgal polypropylene phthalein amine, 10lb/Mgal Xanvis biopolymers.Proppant is adopted
With 170-240 mesh silica flours, proppant dosage is 2,4,6lb/gal.Consider the proppant convection phenomena under the influence of concentration.
2009, Adam Dayan et al. were shown using small-sized transparent parallel scale-model investigation, affected proppant in crack
In laid factor have：Uneven fracture height increases, the leak-off of liquid, the heterogeneity in crack etc..Using flat plate model
The settlement law of research granule has considerable prospect.Need to settle granule and the coupled relation between convection current is deeply ground
Study carefully.
2010, Jiang Tingxue adopted similar narrow slit experimental simulation activated water to take sand fingering pressure break, but load fluid simulation
Shi Bingwei adds proppant, but Bian uses and front put the staining solution that liquid Dot degree ratios are, it is the big Dot of observation that its purpose is only
Fingering phenomenon of the degree than under.
2012, Wen Qingzhi, Zhai Hengli etc. took sand feature using narrow slit model and have done certain research, equipment to activated water
Height, long, wide operational discharge capacity, seam by experimental simulation are wide, proppant particle diameter, Dot degree and sand are than isoparametric substantially rule.Its
As a result still disagree with external theoretical derivation, it should be the restriction of observation method to trace it to its cause
