Foams are widely used to remove liquid loading at the bottom of gas wells improve natural production. However, it becomes ineffective when a well contains large amount hydrocarbon condensate because oil will rupture foams. In this work, oil-tolerant foams were developed and stabilized by mixture cocamidopropyl hydroxyl sulfobetaine (CHSB) sodium dodecyl sulfate (SDS). The foam properties examined different temperatures under atmospheric conditions high pressures with various contents oil. It...
ABSTRACT In this study, a novel quaternary thickener (S−D−HPAM) for low−damage fracturing was successfully synthesized by using acrylic acid (AA) and acrylamide (AM) as the copolymer backbone synchronously introducing octadecyldimethylallyl ammonium chloride (DMCAAC−18) methacryloyloxyethylsulfobetaine (SBMA) bifunctionalized monomer. The structure of S−D−HPAM has been confirmed Fourier transform infrared spectroscopy, hydrogen nuclear magnetic resonance, thermogravimetric analysis, scanning...
Deliquification with chemical foamers has proved a successful and economic technique to unload the liquids from mature natural gas wells; however, no gases are available create foams in low-productivity wells. In this work, situ generated (ISGF) were developed heat produced by reaction of ammonium chloride sodium nitrite presence acetic acid as catalyst, mixture dodecyl sulfate cocamidopropyl hydroxyl sulfobetaine foamer. The molar ratio reactants specifies salt optimized based on...
Abstract Multi‐pulse soliton molecules are observed in passively mode‐locked fiber lasers by using 2D layered metal dichalcogenides (LMDs) as a saturable absorber. LMD has attracted significant attention photonics and optoelectronics which tin disulfides (SnS 2 ) implemented for energy storage, photo‐catalysts, transistor. However, the applications of SnS fields quite rare. Soliton supramolecules self‐assembly optical solitons into highly‐ordered supramolecular structures have not been...
The application effect of the foam deliquification technology in horizontal wells is poor because foaming agent fails to reach target location. In view this, adaptability capillary Western Sichuan Gas Field Basin was analyzed from aspects gas flow rate, liquid rate and casing program wells, design injection depth selection size, tool string parameters (the maximum length minimum counterweight) (foaming type selection, ground concentration rate) were optimized. Then, a standardized operation...
, also known as spotted laurel, is a woody, broadleaf, evergreen shrub with variegated leaves in the Garryaceae family, widely used urban parks, green spaces and landscaping. In October 2019, an outbreak of disease southern blight symptoms was observed on
Abstract Xylosandrus compactus (Eichhoff) (Coleoptera: Curculionidae, Scolytinae) is a worldwide invasive species that causes huge economic loss and environmental damage in many countries. Traditional morphological characteristics make it hard to identify scolytines due their tiny size. Besides, the intercepted insect samples are incomplete, limitation of (larvae pupae) morphology makes identification more difficult. The majority caused by adults fungi serve as nutrition for larvae. They...

The phase shift method of fringe projection technique has attracted much attention for its high-precision, high-speed, and flexible measurement capabilities. But the increase step also means that is more time-consuming. Compared with at least three steps method, two-step important to coordinate speed accuracy. This paper proposes a new based on neural network solve wrapped map. simulation results show this an accurate efficient shifting solution method.
