METHOD TO DEVELOP GAS HYDRATE DEPOSITS USING FOCUSED ACOUSTIC IMPACT ON THE LAYER

摘要

FIELD: oil and gas industry.;SUBSTANCE: invention relates to the extraction of natural gas from gas hydrate deposits and gas deposits, characterized by deposition of hydrates in the bottomhole formation zone. Method development of gas hydrate deposits include heating producing formation near the wellbore through the acoustic impact, and the use acoustic transducer with a frequency range from 20 to 30 kHz and a power input of 15 to 20 kW, whose design uses ultrasonic isolation, enhancing the sound radiation due to the geometry design and having in its structure a vacuum chamber in the form of a prism for turning longitudinal sound waves 90° and an outer side surface in the form of a concave lens for focusing a cylindrical product acoustic radiation at a distance of 5 to 15 meters from the borehole axis.;EFFECT: technical result - high power stimulation without the risk of structural failure of the well.;3 cl, 2 dwg
