FIELD: oil and gas industry.
SUBSTANCE: invention relates to element, which forms tool as such or its component for wells intended for extraction of hydrocarbon resources, including oil and gas. Element of downhole tool for extraction of hydrocarbon resources comprises a moulded body made of resin based on polyglycol acid, having weight-average molecular weight of at least 70,000 and effective thickness equal to or greater than 1/2 of critical thickness of surface decay. Constant speed of reduction of thickness in water depending on time is provided.
EFFECT: creation of element on basis of degradable polymer with possibility of more accurate estimation of change of its mechanical strength during decomposition in time.
