    摘要: A method for increasing the rate of shear rehealing of fluids made with cationic, zwitterionic, and amphoteric viscoelastic surfactant fluid systems by adding an effective amount of a rheology enhancer package containing, for example a polyethylene glycol-polypropylene glycol block copolymer and a polynaphthalene sulfonate. The rheology enhancer package allows viscoelastic surfactant fluids to be used at lower viscoelastic surfactant concentrations in certain applications, for example certain oilfield treatments, for example fracturing and gravel packing. Preferred surfactants are betaines and quaternary amines.

    摘要: A method for increasing the foam stability of foams made with cationic, zwitterionic, and amphoteric viscoelastic surfactant fluid systems by adding an effective amount of an amphiphilic polymeric foam stabilizer containing at least one portion that is a partially hydrolyzed polyvinyl ester or partially hydrolyzed polyacrylate. The foam stabilizer allows foams to be used at temperatures at which the unfoamed fluids would not have stable viscosity, and allows use of lower viscoelastic surfactant concentrations in the liquid phase. Preferred surfactants are betaines and quaternary amines. The fluids are useful in oilfield treatments, for example fracturing and gravel packing.

    摘要: Composition and method for shortening the shear recovery time of cationic, zwitterionic, and amphoteric viscoelastic surfactant fluid systems by adding an effective amount of a co-gelling agent selected from triblock oligomeric compounds having hydrophilic (for example polyether) and hydrophobic (for example alkyl) portions. The co-gelling agent also increases fluid viscosity and very low co-gelling agent concentration is needed. Preferred surfactants are betaines and quaternary amines. The fluids are useful in oilfield treatments, for example fracturing and gravel packing.

    摘要: A large-span and special-shaped arch bridge, comprising a main girder (2), a center abutment (11) served as a central bearing point and two auxiliary abutments (12,13) served as bearing points at two ends, wherein further comprising an arch-axis combination (3) and two arch-axis bending beams (4,5) presented as arcs projected upwards, the arch-axis combination being built on the center abutment (11) with two ends connected to the inner ends of the two arch-axis bending beams (4,5), the outer ends of the two arch-axis bending beams (4,5) being built on the two auxiliary abutments (12,13), the two arch-axis bending beams (4,5) being connected to the main girder (2) via a plurality of inhaul cables. A method for constructing said arch bridge is also disclosed. Through the dual-arch axis of two arch-axis bending beams, the bending strength of the cross-section of the arch bridge is significantly increased, the bending moment of the cross-section of the arch at the central bearing point is decreased, the vertical displacement at the haunch of the arch is lesser, and the deformation of the main girder is reduced, thus the force of the entire bridge is more reasonable, the construction cost can effectively be reduced and the construction period can be shortened.

    摘要: A well treatment composition is formed from a fluid mixture of a viscoelastic surfactant and a liquid carrier fluid. The fluid mixture has rheological properties wherein the mixture exhibits shear-thickening behavior when the shear rate is increased from a first shear rate to a second higher shear rate. The fluid mixture may further include a shear activation additive that interacts with the viscoelastic surfactant to facilitate the shear-thickening behavior. The method is accomplished by introducing the fluid mixture into a wellbore formed in a subterranean formation. In certain applications, the fluid mixture may be recycled by bringing the fluid mixture to the surface and reintroducing the fluid into the same or a different wellbore.
