Abstract
The invention discloses an inflatable suspension proppant for an air bag shell, which structurally comprises a proppant body serving as a core, wherein the surface of the proppant body is coated with an inner coating, and the surface of the inner coating is coated with an outer coating. The inner coating comprises an adhesive and a gas generating agent, wherein the gas generating agent is at least two of ammonium chloride, sodium nitrite, potassium nitrite, urea, sodium carbonate, ammonium carbamate, sodium bicarbonate, ammonium nitrate, potassium nitrate, sodium nitrate, acetylsalicylic acid, citric acid, sulfamic acid and oxalic acid. The outer coating comprises a capsule shell agent, and the capsule shell agent is formed by polymerizing at least two monomers of polyethylene glycol diacrylate, polyethylene glycol dimethacrylate, tert-butyl acrylate, butyl methacrylate and styrene. The gas generating agent is decomposed to generate gas in response to the stimulation of a certain external environment, the outer coating layer wraps and seals the generated gas to form an air bag, and the support agent is supported to realize self-suspension in the slick water under the buoyancy action of the air bag.

Volume fracturing is a mainstream technical approach for developing unconventional oil and gas resources such as shale oil and gas and dense oil and gas. The fracturing fluid system widely applied to the unconventional oil and gas volume fracturing technology at present is mainly slickwater fracturing fluid. Compared with the conventional linear glue and cross-linked glue fracturing fluid, the fracturing fluid has the advantages of low cost, small reservoir damage, strong complex seam network forming capability and the like, but the slickwater has low viscosity and poor sand carrying capability, so that the ore field mainly utilizes large-discharge hydraulic impact to carry sand, the sand ratio is difficult to improve, the propping agent is not uniformly spread, and the yield increasing capability of volume fracturing is greatly limited.
The use of slimy slickwater is one type of solution to the above problems. The method is typically characterized by using low-viscosity slickwater as the pad fluid and high-viscosity slickwater as the sand carrier fluid. However, high viscosity slickwater is usually achieved by increasing the dosage of the drag reducer, which causes high residue of the later-stage gel breaking liquid and damages the reservoir. In addition, the "high viscosity" of high viscosity slickwater is just a relative concept of low viscosity slickwater, and compared with cross-linked glue, the sand carrying capacity is still greatly different, so that the improvement of the sand carrying capacity of high viscosity slickwater is also very limited.
The development of self-suspending proppants that achieve suspension independent of fracturing fluid viscosity is another type of solution. The density of the proppant is reduced or the wettability of the surface of the proppant is changed through the surface adhesion of the coating material, so that the proppant is self-suspended in the fracturing fluid. The coating of the proppant is usually a polymer or hydrophobic material, and for the polymer material, if gel breaking is incomplete, polymer molecules can cause serious reservoir damage, while for the hydrophobic coating material, the existence of surfactants such as foam drainage agents can invert the wettability of the surface of the proppant from hydrophobic to hydrophilic again, so that the proppant loses the self-suspension capacity. In recent years, the interest of petroleum workers is gradually increased, bubbles can be adsorbed on the surface of the proppant by utilizing the affinity of the gas-philic coating and gas, and the self-suspension of the buoyancy proppant based on the bubbles can be realized. However, the gas-philic coating proppant has high construction cost because nitrogen is required to be matched and injected in the construction process, and the proppant loses self-suspension capacity after bubbles are desorbed from the surface of the proppant.

The weight percentage of each component is as follows: 96.2-99.3% of a proppant body, 0.4-1.8% of an inner coating and 0.3-2.0% of an outer coating.
The gas generating agent responds to generate gas under the stimulation of certain external environment (temperature or acidity), the outer coating capsule shell wraps the sealing gas to form an air bag outside the propping agent, so that the gas is prevented from overflowing, and the propping agent is supported to realize self-suspension in the slick water under the buoyancy action of the air bag.
Preferably, the inner coating layer further includes an adhesive agent selected from at least two of tripalmitin, pentaerythritol tetra (stearate), cetylstearyl acetate, acrylic acid, polyurethane, silicone oil, epoxy resin, silane coupling agent, ethylenediamine, and m-phenylenediamine.

In another preferred mode, the outer coating further comprises a capsule shell reinforcing agent, and the capsule shell reinforcing agent is at least one of organic nano montmorillonite, nano silicon dioxide, nano titanium dioxide, nano calcium carbonate, nano graphite powder, a carbon nano tube and nano halloysite. The mass ratio of the capsule shell reinforcing agent to the capsule shell agent is 0: 100.0-1: 49.0.
The preparation method of the inflatable suspension proppant for the air bag shell comprises the following steps:
step 1, dissolving an adhesive in an organic solvent A, and then atomizing and spraying the adhesive on the surface of a proppant body. The organic solvent A is one of petroleum ether, formaldehyde, toluene, dimethylformamide, acetone and xylene.
And 2, uniformly stirring and mixing the proppant body with the adhesive obtained in the step 1 and the gas generating agent powder, and adhering the gas generating agent powder to the surface of the proppant by using the adhesive.
And 3, respectively using the outer coating material and the initiator in the organic solvent B, successively atomizing and spraying the outer coating material solution and the initiator solution onto the surface of the product obtained in the step 2, and standing at room temperature for 6-12 hours to obtain the inflatable suspension proppant for the air bag shell. The outer coating layer is made of a capsule shell agent or a mixture of the capsule shell agent and a capsule shell reinforcing agent. The organic solvent B is one of ethanol, white oil, diesel oil and kerosene.

The raw materials of the capsule shell agent are selected from at least two of polyethylene glycol diacrylate, polyethylene glycol dimethacrylate, tert-butyl acrylate, butyl methacrylate and styrene. In step 3, the raw materials of the capsule shell agent react and polymerize under the action of an initiator under the normal temperature environment to generate the capsule shell agent.
Compared with the prior art, the invention has the advantages that:
(1) the surface of the proppant comprises an inner coating and an outer coating, wherein the inner coating comprises an air generating agent and an adhesive, and the outer coating comprises a capsule shell agent; after the proppant is injected into the stratum, the gas-generating agent generates decomposition reaction to generate gas along with the rise of the temperature of the stratum, and the outer coating wraps and seals the generated gas to form an air bag to prevent the gas from overflowing. Because the air bags are formed on the surface of the propping agent, the propping agent realizes self-suspension in the slick water under the buoyancy action of the air bags. If the temperature of the stratum is low or the temperature is not enough to decompose the gas generating agent to generate gas, a certain amount of slow-release acid (such as sulfamic acid or chloroacetic acid) can be added during the preparation of the sand carrying fluid, and after the sand carrying fluid enters the stratum, the slow-release acid acts to gradually reduce the pH value, and the gas generating agent is decomposed to generate gas under the dual stimulation of the acidity and the temperature of the stratum. The suspension of the gas-filled suspension propping agent of the gas bag shell does not depend on the viscosity of fracturing fluid, and the self-suspension can be realized by inflating the gas bag shell. The suspending capacity is strong, the construction process can reach higher sand ratio, and the proppant in the crack is spread evenly.
(2) The gas-filled suspension proppant of the air bag shell has wide application range to temperature, mineralization and pH and strong oil reservoir environment adaptability.
(3) The gas is not required to be injected in the construction process of the gas-filled suspension proppant of the air bag shell, and the construction cost is low.
(4) The surface of the gas-filled suspension propping agent of the air bag shell is inert, and the gas-filled suspension propping agent has strong compatibility with fracturing fluid additives such as foam discharging agents, antiscaling agents, gel breakers and the like.
