    Abstract: A method includes simultaneously injecting a chemical agent, through an injector, into a perforated wellbore section of a well in a hydrocarbon reservoir, and generating an acoustic wave with an acoustic tool in the wellbore section. The injector and acoustic tool are moved to and fro in synchronization. The acoustic tool includes at least one of a sonotrode and a shock wave tool. A downhole tool assembly comprises the injector, the acoustic tool, and a movable cable hose connected to the injector and the acoustic tool for moving the injector and acoustic tool to and fro in synchronization. The cable hose comprises a wire for supplying power to the acoustic tool and having a conduit for supplying the chemical agent to the injector.

    Abstract: An acoustic waveguide (100) includes a body (101) defining a resonance chamber (102). The body (101) has a tubular section defining a cylindrical central portion (104) of the chamber (102) along a longitudinal axis (108). First and second end sections (110) extend from opposite ends of the tubular section (104). Each end section (110) includes an end wall tapering away from the tubular section and towards the longitudinal axis (108), thus defining a conoidal end portion of the chamber (102).

    Abstract translation: 声波导(100)包括限定谐振室(102)的主体(101)。 主体(101)具有沿纵向轴线(108)限定腔室(102)的圆柱形中央部分(104)的管状部分。 第一和第二端部部分(110)从管状部分(104)的相对端部延伸。 每个端部部分(110)包括远离管状部分并朝向纵向轴线(108)逐渐变细的端壁,因此限定了腔室(102)的圆锥形端部。
