  • Patent number: 10689366
    Abstract: Provided herein are bifunctional compounds that inhibit MALT1 and/or promote targeted ubiquitination for the degradation of MALT1. In particular, provided are compounds that can bind MALT1, a protein whose activity is responsible for constitutive NF-KB signaling in certain cancers (e.g., activated B-cell diffuse large B-cell lymphoma (ABC-DLBCL)), and can assist in its degradation by recruiting an E3 ubiquitin ligase (e.g., Cereblon, VHL), which can ubiquitinate MALT1, marking it for proteasome degradation. Also provided are pharmaceutical compositions comprising the bifunctional compounds, methods of treating cancer with the bifunctional compounds, methods of promoting the degradation of MALT1, and methods of binding E3 ubiquitin ligase activity in a subject by administering a compound or composition described herein.

  • Publication number: 20190300779
    Abstract: The present invention provides a fracturing process, which comprises the following steps of: injecting a fracturing fluid into the formation to cause fractures in the formation and stopping the injection of the fracturing fluid after the fracture as produced reaches a preset requirement; injecting a phase transition material fluid capable of undergoing a phase transition reaction at a preset temperature and a delayed heat generating agent into the formation, wherein the delayed heat generating agent functions to generate heat after the injection of the phase transition material fluid is substantially completed, so as to cause a phase transition of the phase transition material fluid to complete the fracturing. The technical solution provided by the present invention can effectively reduce the friction resistance of the pipe string; moreover, the use of a delayed heat generating agent can effectively control the initiation and progress of the phase transition reaction.

  • Patent number: 10364388
    Abstract: The present invention discloses a phase change fracturing fluid system for phase change fracturing, including the following components in percentage by weight: 10%-40% of supramolecular construction unit, 0-40% of supramolecular function unit, 0.5%-2% of surfactant, 0-5% of inorganic salt, 0.5%-2% of oxidizing agent, 0-2% of cosolvent and the remaining of solvent. The supramolecular construction unit is melamine, triallyl isocyanurate, or a mixture thereof. The supramolecular function unit is vinyl acetate, acrylonitrile, or a mixture thereof. The solvent is methylbenzene, ethylbenzene, o-xylene, m-xylene or p-xylene. In the fracturing construction process, a conventional fracturing fluid is used for fracturing a formation first; the phase change fracturing fluid is then injected into the formation, or the phase change fracturing fluid and other fluids which cannot be subjected to phase change are injected into the formation together.

  • Patent number: 10301919
    Abstract: A phase-change hydraulic fracturing process, including the following steps: (1) injecting clean water or conventional fracturing fluid to a formation, so that the formation fractures; (2) placing non-phase-change liquid and phase-change liquid in different liquid mixing tanks and injecting into a shaft at the same time, an injection volume ratio of the non-phase-change liquid to the phase-change liquid is (0-0.7):(0.3-1); (3) injecting a displacement fluid into the shaft, so that the non-phase-change liquid and the phase-change liquid in the shaft completely enter a reservoir; (4) performing well shut-in and pressure-out for 30-200 min, so that solid-phase matters generated by the phase-change liquid are laid in the fracture; and (5) relieving pressure to finish the construction.
