24 - در این مقاله به بحث وبررسی تکنولوزی حفاری با لیزر که اساسی ترین جایگزین برای حفاری دورانی می باشد ،پرداخته می شود ما ابتدا با تاریخچه کوتاهی از آزمایشاتی که قبلا در موسسات دیگر انجام شده است می پردازیم .در ادامه با ذکر پارامتر های موثر بر روی کاهش مقدار انرزی مخصوص سنگ ودر نتیجه افزایش مقدار سرعت حفاری ف به بررسی این موارد خواهیم پرداخت .موضوع دیگری که در این آزمایش به آن اشاره خواهد شد ،تاثیرات لیزر بر روی سرعت حفاری ،هزینه های حفاری وهم چنین محیط زیست می باشد .ودر آخر با داده هایی که از آزمایشات مختلفی که در طی این تحقیق بدست آمده است اثبات خواهد شد که این نوع حفاری نوین می تواند جایگزین مناسب ومقرون به صرفه ای به جای حفاری دورانی باشد .حفاری با لیزر یکی از راه کار های موثر ومناسب جهت حفاری وعملیات مشبک کاری سازند های سخت ومتراکم با عمق زیاد می باشد .یکی از مزایای استفاده از لیزر جهت حفاری چاه های نفت وگاز ،توانائئ کاهش مدت زمان حفاری می باشد .در حفاری با لیزر به جهت تماس نداشتن با سطح سنگ در حین حفاری وجلو گیری از توقف حفاری برای تعویض مته ، در مدت زمان حفاری صرفه جوئی عمده ای صورت خواهد گرفت .
