Description
Technical field
The present invention relates to a kind of preparation method of fracturing propping agents and the fracturing propping agents that prepared by this preparation method, and a kind of deep well fracturing method.
Background technology
In the fracturing technology of oil, Sweet natural gas deep mining and ultra deep well, all can use fracturing propping agents, the effect of fracturing propping agents is the sand packed fractures that form a high flow conductivity in the stratum, and the passage of hypertonicity is provided for the circulation of oil gas.Therefore, fracturing propping agents need to have certain intensity and flow conductivity, to satisfy the closure stress requirement on different depths stratum.
At present, the more fracturing propping agents of field use mainly are haydite and quartz sand.But the percentage of damage of haydite and quartz sand is high, and the haydite of crushing in reservoir easily moves, and flow conductivity is poor.Resin-coated sand propping agent also is widely used in recent years, and this propping agent can obtain by the type of regulating resin the propping agent of various different performances, for example, when gathering oil, adopts lipophilic resin can improve recovery ratio.The existing method for preparing resin-coated sand normally joins additive in the resin and utilizes mechanical stirring to mix, and still, adopts the consumption of the method resin large, and the unstable properties of the fracturing propping agents that obtain, percentage of damage is high, flow conductivity is poor.
Summary of the invention
The object of the invention is to overcome when adopting existing method to prepare fracturing propping agents, resin demand is large, and the product percentage of damage that obtains is high, the poor defective of flow conductivity, a kind of resin demand that reduces is provided, and can accesses the preparation method of the fracturing propping agents that percentage of damage is low, flow conductivity is strong and the fracturing propping agents that prepare by the method and a kind of method of deep well fracturing.
The invention provides a kind of preparation method of fracturing propping agents, wherein, the mixture that will contain additive and molten resin is mediated evenly, and mixes, solidifies with aggregate, so that aggregate surface forms coating layer.
The surface coated resin layer of the fracturing propping agents that adopt method of the present invention to obtain can prevent effectively that the aggregate chip from escaping, thereby keeps the ability of fracture guide, improves the recovery ratio of oil or Sweet natural gas.The present inventor finds, because intensity and the antistatic effect of resin are relatively poor, can improve the performance of described resin behind the adding additive.But adopt the existing method that additive is joined in the resin and utilizes mechanical stirring to mix, the performance of the fracturing propping agents that obtain is also unstable and percentage of damage is higher.Inferring reason, may be because the viscosity of described resin is larger, can not make additive Uniform Dispersion in resin by mechanical stirring, and the composition heterogeneity of aggregate coating layer can cause the heterogeneity of single particle strength and coating thickness.At present, prior art adopts the consumption that increases resin to improve the performance of described fracturing propping agents usually.And the present invention is with after the resin heating and melting, again additive is added under the kneading effect, can be so that described additive be evenly dispersed in the resin, the fracturing propping agents that obtain have larger intensity, lower percentage of damage and more stable performance, and the consumption of resin also can reduce.
The present invention also provides the fracturing propping agents that prepared by aforesaid method.
In addition, the present invention also provides a kind of deep well fracturing method, and the method is included in the bottom of deep-well and forms the crack, and fracturing propping agents are filled in the crack, wherein, and the fracturing propping agents of described fracturing propping agents for being prepared by aforesaid method.
Other features and advantages of the present invention will partly be described in detail in embodiment subsequently.
