Description

Technical Field

[0001] The present invention relates to the technical field of oil production, and in particular to a high-viscosity elastic jelly granulation device, a high-viscosity elastic jelly granulation system and a high-viscosity elastic jelly granulation method. Background Art

[0002] Water injection to displace crude oil is a commonly used production-increasing measure in the field of oil extraction. However, due to the influence of reservoir heterogeneity, the water injected into the reservoir or the natural marginal water of the reservoir is prone to crossflow, resulting in a higher water content and a lower oil content in the oil well produced fluid, resulting in lower production efficiency.

[0003] High-viscosity elastic jelly is recognized by the industry as a "good medicine" for controlling water and increasing oil production in high-water-content oil fields, but it faces difficulties in controlling water deep in reservoirs, especially for high-temperature and high-salt oil reservoirs. High-viscosity elastic jelly gels quickly and cannot migrate deep in the formation. Existing shearing equipment, such as emulsifiers, homogenizers, colloid mills, etc., can achieve shear preparation of single brittle or viscous material systems, such as brittle solids such as soybeans and wheat, or viscous fluids such as heavy oil. However, for jelly systems with both high viscosity and elasticity, it is difficult to achieve efficient shear granulation, resulting in a short effective period of water control and poor water control effect.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] Reservoir heterogeneity is the main factor affecting the efficient development of oil reservoirs. Injecting high-viscosity elastic jelly is an effective technical means to regulate reservoir heterogeneity. Since high-viscosity elastic jelly gels gel quickly and cannot migrate deep in the formation, high-viscosity elastic jelly faces difficulties in deep reservoir water control. Existing shearing equipment, such as emulsifiers, homogenizers, colloid mills, etc., can achieve shear preparation of single brittle or viscous material systems, such as brittle solids such as soybeans and wheat or viscous fluids such as heavy oil, but for jelly systems that have both high viscosity and elasticity, it is difficult to achieve efficient shear granulation. In response to the above problems, the present invention provides a high-viscosity elastic jelly granulation device, system and method to achieve shear granulation of jelly that has both high viscosity and elasticity, thereby preparing jelly particles, which is beneficial to the migration of high-viscosity elastic jelly in deep formations and achieves better deep water control effects.

[0055] The first aspect of the present invention provides a high-viscosity elastic jelly granulation device, referring to Figure 1 and Figure 2 As shown, the granulation device includes: a stator assembly 1 and a rotor assembly 2 which are coaxially sleeved and connected, a shear space is formed between the stator assembly 1 and the rotor assembly 2, and a plurality of staggered teeth are arranged in the shear space for shearing the high-viscosity elastic jelly to form jelly particles, and the number of the staggered teeth gradually increases along the conveying direction of the high-viscosity elastic jelly.

[0056] In the high-viscosity elastic jelly granulation device provided by the present invention, the rotor assembly 2 can rotate relative to the stator assembly 1, and the stator teeth in the shear space can be set on the rotor assembly 2 and / or the stator assembly 1. After the high-viscosity elastic jelly is transported into the shear space, the rotor assembly 2 starts to rotate, so that the stator teeth shear the high-viscosity elastic jelly. Along the transport direction, as the number of staggered teeth gradually increases, the particle size of the sheared jelly gradually decreases, and the shape gradually becomes regular, so that jelly particles with controllable particle size and regular shape are prepared. Since the jelly particles have good viscoelasticity, they can be deformed in the formation according to the pore size and shape, so that they can be transported to the deep formation, thereby improving the water control effect of the jelly in the deep formation.

[0057] In some embodiments, along the conveying direction of the high-viscosity elastic jelly, the shear space includes a pre-shearing chamber, a crushing chamber, and a rounding chamber, the number of staggered teeth in the pre-shearing chamber is less than the number of staggered teeth in the crushing chamber, and the number of staggered teeth in the crushing chamber is less than the number of staggered teeth in the rounding chamber. After the high-viscosity elastic jelly is conveyed into the shear space, it is first sheared in the pre-shearing chamber, and then enters the crushing chamber with a larger number of staggered teeth for shearing to further reduce the particle size of the high-viscosity elastic jelly, and finally enters the rounding chamber to further reduce the particle size of the high-viscosity elastic jelly and make the shape of the high-viscosity elastic jelly gradually regular, such as forming a sphere, to obtain jelly particles.

[0058] Of course, according to actual production needs, there can be multiple pre-shearing chambers, crushing chambers and rounding chambers, or the jelly particles output from the rounding chamber can be further transported back to the pre-shearing chamber for multiple cycles of shearing to ensure that the jelly particles that meet production requirements are obtained.

[0172] Along the transportation direction of the high-viscoelastic jelly, the number of staggered teeth gradually increases. When the high-viscoelastic jelly is subjected to multi-stage shearing, the particle size of the sheared jelly gradually decreases and the shape gradually becomes regular, thereby preparing jelly particles with controllable particle size and regular shape. Since the jelly particles have good viscoelasticity, they can be deformed in the formation according to the pore size and shape, and can thus be transported to deep formations, thereby improving the water control effect of the jelly in deep formations.

[0178] In some embodiments, the spacing between any two adjacent pre-shearing rotor teeth 212, crushing rotor teeth 222, and rounding rotor teeth 232 is 1-5 mm, and / or the spacing between any two adjacent pre-shearing stator teeth 142, crushing stator teeth 152, and rounding stator teeth 162 is 1-5 mm.

[0180] In some embodiments, in the multi-stage shearing, the shearing time of the high-viscoelastic jelly is not less than 240 s.
