Embodiment 1

[0037] Heat 2 kg of quartz sand (particle size 0.425 / 0.85mm) to 170°C and pour it into a mixer, stir to cool down to 160°C, 1) add 0.5 g of γ-aminopropyltriethoxysilane and phenolic Stir 40 grams of resin for 50 seconds to make it evenly coated on the quartz sand, add 8.0 grams of hexamethylenetetramine and stir for 60 seconds; 2) Add 50 grams of epoxy resin and stir for 60 seconds, add 12.0 grams of alicyclic polyamine Stir and solidify for 60 seconds; 3) Add 4.2 g of an amino-terminated organosilicon compound, stir and solidify for 150 seconds, cool and sieve to obtain a functional resin-coated quartz sand proppant.

Embodiment 2

[0039] The first two steps are the same as example 1, 3) when the material starts to agglomerate, add 6 grams of calcium stearate and continue to stir and solidify for 150 seconds, cool, crush, and sieve to obtain the resin-coated quartz sand proppant.

Abstract

The invention relates to a functional resin tectorial membrane proppant and a preparation method thereof, and belongs to the technical field of oil-gas field development. The functional resin tectorial membrane proppant comprises aggregate and a resin film coated on the aggregate. Said resin film comprises organic silicon compounds of one or more active groups of amino, hydroxyl, carboxyl, alkoxyl and hydrosulphonyl. The side chain of the organic silicon compound is a hydrophobic group. The cured resin film has different wetting qualities for oil and water. The functional resin tectorial membrane proppant of the invention has a function of allowing the smooth permeation of oil gas and preventing water from penetrating through the proppant. Such a function improves the separation effect ofoil gas and water and reduces the oil production cost. The excellent hydrophobicity of the resin film facilitates the proppant to have excellent water resisting property and improves the crushing resistance of the proppant, so that the stream guidance effect is good for a long time.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to a resin-coated proppant used in the field of oil and gas fields, which has the functions of promoting oil and gas permeation and preventing water from passing through, and a preparation method thereof. The proppant keeps hydraulic fractures open and has differential wettability to oil and / or gas, water, thereby greatly improving the specific recovery of each well. Background technique [0002] In the process of exploration and development of oil and gas fields, especially in the exploration and development of low-permeability and ultra-low-permeability oil and gas fields and the reconstruction of old oil and gas wells, fracturing has become the main means of increasing production and improving recovery. [0003] In the fracturing process, the role of proppant is extremely important. When fractures are formed in the formation, the addition of proppant keeps the fractures supported. The p...
