| titleOfInvention | Low-viscosity plugging system for fractured reservoir and preparation method thereof |
| abstract | The invention discloses a fractured oil reservoir low-viscosity plugging system and a preparation method thereof, and the fractured oil reservoir low-viscosity plugging system comprises an adsorbent, a nano capsule shell with a hole, a resistance-increasing protective film and a degrading agent, wherein the adsorbent is coated in the nano capsule shell with the hole, the resistance-increasing protective film is coated outside the nano capsule shell with the hole, the mass ratio of the adsorbent to the nano capsule shell with the hole to the resistance-increasing protective film is 2:2:1, and the mass concentration of the nano capsule shell with the hole in the degrading agent is 10-15%. The low-viscosity plugging system for the fractured reservoir has the viscosity close to that of water, is suitable for reservoirs with various permeability, is easy to enter the deep part of the reservoir, plays a role in deep plugging, has the characteristics of low viscosity before and during injection, and is adsorbed on the wall of a rock hole after reaching the fracture for a period of time, thereby greatly increasing the seepage resistance, and can achieve the purposes of expanding the non-main seepage channel fracture and the sweep efficiency of matrix and improving the crude oil recovery rate of the fractured reservoir. |
