FIELD: well research, possible use for determining and controlling static and dynamic oil level in product wells. ^ SUBSTANCE: in accordance to method, signal s0(t) is generated in form of a sum of rectangular impulses, changing time of n-th impulse and its duration depending on n. Generated signal s0(t) is sent to generator of acoustic signal for generation thereof. Acoustic signal s1(t) reflected from liquid is transformed to electric signal and subjected to analog-digital transformation. Signal s0(t) is subjected to folding operation with digitized reflected signal s1(t), and then temporary position of signal reflected from liquid is determined relatively to moment of generation of acoustic signal in inter-tubular space, using which, level of liquid is determined. ^ EFFECT: possible control over level of liquid in wells with high value of signal/noise ratio, resulting in decreased probability of error during computation of level. ^ 5 dwg, 3 tbl |
