Description
Technical field
The present invention relates to a kind of oil-gas field construction material, especially a kind of sand control material of oil-gas field, belong to oil gas drilling and production technology field.
Background technology
Current oil field uses the fibrous plug with having certain length to carry out shutoff sand prevention, and shortcoming to guard against the grains of sand of trickle particle diameter; Or be fixed on perforation place with screen casing, block the grains of sand, screen casing is metal, can form certain incrustation scale or salt grain under the effect of certain temperature and salinity, thus blocks screen casing mesh and lose the effect of sand control; Or inject to enter to block up temporarily with oil well cement, then untie or dredge the passage thus the object reaching sand prevention with certain pore size with certain chemical reagent, shortcoming is that oil well cement solidifies and can shrink, and cannot guard against the fine sand that particle diameter is little.Such as Sebei Gas Field is not only loosened on stratum, and gas well shakes out seriously, and continually developing along with gas field, water-gas ratio rises very fast, and its reservoir is mainly siltstone and pelitic siltstone, and cementing matter is based on shale, rock grain size is flour sand level-fine sand level, particle diameter 0.01-0.4mm, reservoir undercompaction, poor diagenetic grade, loose cementation, shakes out serious, in process of production, relatively thin sand grains is brought to ground, and relatively thick sand grains sinks to shaft bottom.In formation sand production, percentage ratio shared by flour sand is about 48%, and in the sand that gas well is discharged, shared by flour sand, percentage ratio is about 80%, and without coarse sand, medium sand proportion is minimum, mean particle size 0.04-0.07mm, and sand prevention difficulty is very big.
Summary of the invention
Goal of the invention of the present invention is: for above-mentioned Problems existing, provides a kind of sand control liquid adopting oil-gas field fracturing formula constructional method, to overcome the shortcoming of existing sand control technique, improves the sand controlling result of oil-gas field.
The technical solution used in the present invention is as follows:
A kind of oil-gas field fracturing formula sand control liquid, comprise fracturing liquid and the unequal haydite composition of particle diameter, the particle size distribution range of described haydite is 20-140 order.
Further, described haydite is with following specification and mass ratio batching: 20-30%, 100-140 order that 60-70%, 60-100 order that 20-60 order accounts for haydite total amount accounts for haydite total amount accounts for the 2-10% of haydite total amount.
Oil-gas field fracturing formula sand control liquid of the present invention, also comprises fibre object.
Further, described fibre object length is 2.5-3.1mm, and fineness is 5000-6000 public affairs, and the add-on of fibre object is the 5-12% of haydite total mass.
Oil-gas field fracturing formula sand control liquid of the present invention, containing gel breaker in described fracturing liquid.Gel breaker can be oxidized to of the fracturing fluid polymer molecule the effect played and interrupt molecular chain, thus make fracturing liquid lose viscosity and elasticity, return and discharge ground, its consumption carries out according to of the fracturing fluid construction reference, be not generally of the fracturing fluid 0.05% ~ 0.1% not etc., vary with temperature use, the lower consumption of temperature is higher.
Sand control liquid of the present invention can not formation damage, the salt solution that high salinity met in the earth formation by this fracturing liquid can shrink molecular chain automatically, viscosity can be reduced, the natural condition of formation temperature in addition, the chemical action of gel breaker can make of the fracturing fluid molecular rupture very soon, thus the breaking glue solution forming noresidue returns discharge ground, can not result in blockage to gas channel; Haydite can fill the stratum of the deficit owing to shaking out; play a supportive role; due to the particle size dispersion of haydite; microfine particle is made to clamp-on coarse grained space; and microfine particle is as far as possible close to formation sand production particle diameter; will form the natural plugged zone of a performance like this, guard against formation particle, the optimum mix amount of haydite is of the fracturing fluid 18% ~ 27%.Sand control liquid also adds fibre object in addition, makes to improve sand control capability further, compared to existing independent interpolation, at utmost prevents the grains of sand of trickle particle diameter.
Described fracturing liquid does not need to be construed as limiting type, adopt the fracturing liquid of oil-gas field routine, its use-pattern is determined according to fracturing liquid service requirements, can just define a kind of existing viscosity resilient fracturing liquid again in the supplementary thickener of adding certain ratio in the liquid of certain viscosity that has of host preparation, be added into gel breaker according to of the fracturing fluid using method.And the indwelling amount of fracturing liquid in bottom is also divided into conventional fracturing liquid and clean fracturing fluid.
A kind of oil-gas field fracturing formula sand control liquid constructional method, the oil-gas field fracturing formula sand control liquid described in employing, comprises following steps:
A (), to underground sand-prevention layer reverse-pressure perforating, hole density is 12-20 hole/m, and aperture is not less than 10mm;
B () uses Solid Free cleaning liq well-flushing;
C () passes to hydrocarbon zone below lower bound 10m with the drift size gauge tool being less than casing inner diameter 4-6m, without being hampered phenomenon;
D () to above 5-10m position, hydrocarbon zone top circle with sand control pipe under blank tubing, installs well head and constructs;
E () is according to sanding formation thickness and perforation radius calculation construction consumption;
F the minute-pressure of described oil-gas field fracturing formula sand control liquid is split feeding sanding formation with fracturing truck by ();
G () stops fracturing truck work, pressure release after reservoir pressure slow releasing after reaching and dropping into metering, subsequently lift pipe string, under enter screen casing.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: oil-gas field fracturing formula sand control liquid of the present invention, sanding formation is entered in varing proportions with the haydite of specification, after the plugged zone that the tightly packed formation of haydite is certain, stop injecting fracturing liquid and haydite, fracturing liquid to be cleaned is under the effect of well environment or gel breaker effect, and broken glue becomes the liquid as clear water to return discharge ground; The haydite of different-grain diameter distribution is in the earth formation resident, form the relatively stable and filtering layer that strainability is good, thus reaching the effect of sand control, the fibre object wherein added effectively can form hinge layer in the haydite layer formed, and strengthens stability and the sand control capability of haydite layer further.
Oil-gas field fracturing formula sand control liquid constructional method of the present invention, adopt and split with the minute-pressure of oil-gas field fracturing similar process, and carry out process optimization for sand control liquid and sand control construction, its algorithm is simple, operation mature and reliable, sand control process can be carried out efficiently, by after this art breading there is the advantage that sand controlling result is good, sand control stability is strong to oil-gas field.
