Description
Technical Field
The invention belongs to the technical field of petroleum propping agents, and particularly relates to a petroleum fracturing propping agent and a preparation method thereof.
Background
In oil and gas exploitation of oil fields, a fracturing process is widely adopted for improving the oil well yield, prolonging the high-yield life of the oil well and exploiting resources which are difficult to use. To prevent closure of the subterranean fracture, the hydrocarbon passages are preserved, the conductivity is maintained, and proppants must be used to fill the fracture. Petroleum proppants are also known as petroleum fracturing proppants. When petroleum and natural gas deep well is mined, after the high-closure pressure low-permeability ore deposit is subjected to fracturing treatment, the oil-gas-containing rock stratum is cracked, oil gas is collected from channels formed by the cracks, at the moment, fluid is required to be injected into a rock base layer to exceed the pressure of the fracture strength of the stratum, the rock stratum around a shaft is cracked, a channel with high laminar flow capacity is formed, and in order to keep the cracks formed after fracturing open, oil gas products can smoothly pass through.
In recent years, with the development of petroleum fracturing proppants in China, the proppants are not limited to two conventional types of quartz sand and ceramsite. Various proppants have emerged, such as coated proppants, concretionable proppants, and selectively oil-permeable and water-blocking proppants. The flow conductivity of the resin coated propping agent is superior to that of quartz sand and ceramsite, mainly because the crushed quartz sand and ceramsite are wrapped inside by the coating resin on the outer layer, broken fine particles are prevented from blocking crack channels, and the flow conductivity is reduced. However, the resin coated propping agent is generally made of quartz sand or ceramic with higher density, so that the density of the fracturing propping agent is still higher, and polymer viscous fracturing fluid is needed to be used for pressing in and discharging the fracturing propping agent, which definitely causes construction difficulty and is inconvenient to pump into the well.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a petroleum fracturing propping agent and a preparation method thereof.
According to the invention, hollow glass beads and slag micropowder are used as supporting materials, and the supporting materials and epoxy resin are used for preparing the petroleum fracturing propping agent together, so that the product with low density, high strength and strong crushing resistance is obtained. The petroleum fracturing propping agent obtained by the invention has low density, so that polymer fracturing fluid is not needed or used less, and water can be directly used as the fracturing fluid for conveying, thereby reducing the use of the fracturing fluid and simplifying the fracturing construction process.
The aim of the invention can be achieved by the following technical scheme:
the preparation method of the petroleum fracturing propping agent comprises the following steps:
firstly, mixing hollow glass beads and slag micro powder, soaking for 8-10min by alkali liquor, taking out, washing to neutrality, drying, and carrying out grafting modification treatment on the surface by using a silane coupling agent KH792 to obtain a pretreated supporting material;

mixing the dried powder with ethanol water solution (volume fraction 50%) according to the ratio of 1g to 15mL, performing ultrasonic dispersion for 10min, adding a silane coupling agent KH792, heating to 80 ℃, stirring and refluxing for 4-5h, filtering, washing with distilled water for 3-4 times, and fully drying to obtain a pretreated supporting material; the adding amount of the silane coupling agent KH792 is 2-3 times of the mass of the powder.
Further, the specific operation of the second step is as follows: dissolving chloropolyethylene glycol in DMF according to a mass ratio of 1:9, uniformly mixing and dissolving, mixing with a pretreatment support material according to a solid-to-liquid ratio of 1g:20mL, stirring for 4-5h, filtering, washing with ethanol for 3-4 times, and fully drying to obtain a modified support material; silane is grafted on the surface of the pretreated supporting materialMolecular chain of coupling agent KH792, containing-NH thereon 2 Can react with chloro polyethylene glycol, thereby grafting polyethylene glycol molecular chains on the surface of the support material to obtain the modified support material.
Further, the grain size of the slag micropowder is 15-25 μm.
Further, in the first step, the alkali liquor is any one of sodium hydroxide solution, potassium hydroxide solution and calcium hydroxide solution, and the pH value of the alkali liquor is 10-12.
Further, the viscosity of the methyl silicone oil is 10 Pa.s; the curing agent is curing agent MTHPA, the accelerator is accelerator DMP-30, and the toughening agent is polytetrahydrofuran toughening agent PTMG3000.
Further, the dosage ratio of the epoxy resin, the curing agent, the accelerator, the toughening agent, the modified supporting material and the methyl silicone oil is 100g to 80 g to 85g to 2 g to 3g to 5g to 6g to 7 g to 10g to 3000mL.
Further, the mass ratio of the hollow glass beads to the slag micropowder is 3:2.
The modified supporting material is prepared by modifying hollow glass beads and slag micropowder; besides ultra-low density, the hollow glass microsphere has the characteristics of high compressive strength, high melting point, high resistivity, small thermal conductivity coefficient and thermal shrinkage coefficient and the like, and can obtain higher anti-crushing capability by taking the hollow glass microsphere as one of supporting materials; the slag micropowder has small particle size, slag has the advantages of high temperature resistance and high strength, and can also promote the comprehensive performance of propping agents; on one hand, the interfacial compatibility of the support material and the epoxy resin can be improved, and the dispersion performance is further improved; on the other hand, an interpenetrating polymer network can be formed between a flexible polyethylene glycol molecular chain and an epoxy resin molecular chain, so that carrying and dispersing capacities of the support material are further enhanced, and the finally prepared microsphere is high in strength and excellent in sphericity.
The invention has the beneficial effects that:
according to the invention, hollow glass beads and slag micropowder are used as supporting materials, and the supporting materials and epoxy resin are used for preparing the petroleum fracturing propping agent together, so that the product with low density, high strength and strong crushing resistance is obtained. The petroleum fracturing propping agent obtained by the invention has low density, so that polymer fracturing fluid is not needed or used less, and water can be directly used as the fracturing fluid for conveying, thereby reducing the use of the fracturing fluid and simplifying the fracturing construction process.
