Patent number: 11015109Abstract: A particulate profile control agent self-adaptive to a size of formation pore throat and a preparation method thereof include: raw materials and mass fraction for preparing a system including a main agent of 0.04˜0.2%, a nucleating agent of 0.005˜0.01%, a crosslinking agent of 0.002˜0.04%, an additive of 0.005˜0.01% and water. The preparation method includes: adding the main agent in proportion to the water and evenly mixing the mixture of the main agent and the water, and then adding the additive, the crosslinking agent and the nucleating agent in turn so as to form the profile control agent; pumping the profile control agent into the formation to be reacted at a reservoir temperature for a period of time to form colloidal particles on the spot for sealing off a high-permeability layer. The present disclosure is of easy operation and low cost, low initial viscosity and good injectivity.Type: GrantFiled: October 15, 2020Date of Patent: May 25, 2021Assignee: Southwest Petroleum UniversityInventors: Fayang Jin, Daijun Du, Wanfen Pu, Xiang Li, Ye Ju, Kexing Li, Lin Sun, Rui Liu, Shuyu Song, Mian Wang, Wei Liao, Desheng Qian

Patent number: 10876032Abstract: Disclosed is a composition and use thereof for the recovery of hydrocarbon fluids from a subterranean reservoir. More particularly, this invention concerns ?-glycol containing sulfonated epoxy resin composition and method for preparing said composition. The ?-glycol containing sulfonated epoxy resin composition is made by forming a reaction product comprising an epoxide-containing compound, a primary amino sulfonate, and optionally one or more of a primary monoamine alkylene oxide oligomer, followed by converting any unreacted epoxide groups in the reaction product to ?-glycol groups by hydrolysis. Said ?-glycol containing sulfonated epoxy resin compositions demonstrate good solubility in aqueous solutions and are useful for modifying the permeability of subterranean formations and increasing the mobilization and/or recovery rate of hydrocarbon fluids present in the formations.Type: GrantFiled: June 26, 2017Date of Patent: December 29, 2020Assignee: Dow Global Technologies LLCInventors: Stephen M. Hoyles, Robert E. Hefner, Jr.
