Description
Technical field
The present invention relates to a kind of polymer viscosifier for pressing crack construction, in particular for the liquefaction polymer viscosifier of the continuous mixture of pressing crack construction.
Background technology
In oilfield exploitation procedure, pressing crack construction has become transformation storage and has increased the requisite ring of output.In pressing crack construction process, workmen need to use a large amount of fluids, and we are referred to as fracturing liquid conventionally; This fluid is transported to pit shaft by high-pressure pump by ground, and produces pressure (effect of liquid pressure transmission) at pit shaft; In the time that the pressure producing is greater than the terrestrial stress of the borehole wall and tensile strength of rock, the borehole wall has just produced crack.These newly-generated cracks provide oil gas to enter the passage of pit shaft.In order to keep these cracks, we need to add propping agent in fracturing liquid, such as sandstone, ceramic particle, high-intensity polymer materials etc.These propping agents are along with fracturing liquid enters and remains in crack, to bear reservoir pressure; After stopping pumping fracturing liquid, due to the existence of propping agent, crack just can be not closed under the effect of reservoir pressure.Carry the fracturing liquid of these propping agents can be divided into two types: the first is the aqueous fracturing fluid with water compositing dispersion medium; The second is the oil base fracturing fluid using oil phase as dispersion medium.Aqueous fracturing fluid has the following advantages compared with oil base fracturing fluid: 1) production cost lower (water is more cheap than oil), 2) safety performance higher (oil can burn).Therefore, the application of aqueous fracturing fluid is more extensive.In order to transmit pressure, fracturing stratum, carries propping agent, and fracturing liquid must have certain viscosity.Current, in aqueous fracturing fluid, conventionally contain a certain proportion of wetting ability thickening material and carry out adjusting viscosity.This thickening material uses waterborne polymeric conventionally, such as guanidine glue, Mierocrystalline cellulose, xanthan gum, guanidine gum derivative, derivatived cellulose, xanthan derivatives etc.Itself can increase liquid viscosity these polymkeric substance, then has added after linking agent, and the viscosity of its aqueous solution can further improve.
The compound method of above-mentioned waterborne polymeric or the fluid of other polymkeric substance can be the method for batch mixed or the method for continuous mixture.The implication of batch mixed is: before pumping into down-hole, polymkeric substance and additive (such as sterilant, polymkeric substance, inorganic salt, buffer reagent, acid or alkali, clay stabilizer etc.) mix with water in material-compound tank; Mix and leave standstill later for some time, until polymkeric substance aquation in water completely.Batch mixed can ensure the quality of configured liquid, but has also caused the waste of material.This is owing to there being certain parameter in site operation process, these parameters cause final consumption that cannot accurate calculation liquid, therefore, designer is calculating and on the basis of spent material, can add certain safe clearance, and the increase of these safety using amounts has caused waste.Boring in completion technique service industry, the severe challenge that the continuous rising Ye Shi enterprise of cost faces always.The method of batch mixed, except waste material, also causes the rising of cost.Adopt in the process of batch mixed method preparing fracturing fluid, well site needs a large amount of liquid of storage and maintenance, and this has just caused high cost; The existence of safe clearance, causes again the further raising of cost.Mixture is also a kind of burden to environment protection in batches.Ecological environmental protection requires zero waste in process of production without abandoning.But in the engineering of batch mixed method preparing fracturing fluid, a large amount of residual liquid is often arranged at the bottom of material-compound tank, how processing these residues becomes the very thorny environment difficult problem that slip-stick artist need to face.Different from batch mixture, mixed technology is a kind of method that basis need to configure liquid in real time continuously.Mixed technology can overcome the easy waste of above-mentioned batch mixed technology continuously, and cost is high, the disagreeableness various shortcoming of environment.This real-time continuous mixed technology can measure the quantity of each material at the scene accurately, and it is unnecessary or residual can not produce in process of production.Mixed technology can be realized real-time formulated fluids continuously, according to adding in real time material, at utmost reduces the waste of material, reduces unnecessary cost.
In continuous mixed technology, workmen needs a kind of simple and quick method that measures thickening material.A very cost-effective method adopts pumping system exactly.Adopt pumping system can control the volume of fluid, also without adding extra equipment.But pumping system requires thickening material preferably to exist with liquid instead of with solid form.At present, thickening material, as guanidine glue, Mierocrystalline cellulose, xanthan gum, guanidine gum derivative, derivatived cellulose, xanthan derivatives, exists with solid state powder conventionally.These solid polymers are applied to continuous mixed technology following difficulty: 1) need to add extra control device and measure material; 2) disperse inhomogeneously, hydration rate is slow, 3) easily produce flake and caking.Therefore, how to overcome the above-mentioned shortcoming of solid-state thickening material, develop a kind of thickening material based on liquid polymer systems, become the problem that first continuous mixture and batch production pressure break must solve that realizes.
Summary of the invention
In order to overcome the various shortcoming that uses the existence of solid thickening material in fracturing liquid preparation and construction, meet the needs that Hydro Fracturing Stimulation Treatment scale expands gradually, realize continuous mixture and large-scale industrialized pressure break, the invention provides a kind of liquefaction polymer viscosifier of the continuous mixture for pressing crack construction.
