摘要： A method for wellbore perforation in which a section of the wellbore to be perforated is isolated and purged of wellbore fluid to provide a clear path for laser beam transmittal. A laser beam emitter in the purged wellbore section transmits a laser beam pulse from the laser beam emitter to a target area of a sidewall and formation lithology of the purged wellbore section, thereby altering a mechanical property of a material of the sidewall and formation lithology and producing material debris. A liquid jet pulse of a liquid is transmitted immediately following termination of the laser beam pulse to the target area, thereby removing the material debris from the target area. This cycle is then repeated until the desired perforation depth has been achieved.
