Abstract


Due to the complexity of geological and field conditions of well constructions and reduction of their mining opportunities (velocity, drifting) the defining role is played by indicators that characterize the quality of the work carried out. The article considers an overview of the quality of well construction indicators including field-geophysical researches by acoustic method with the use of the ACC8CM device.
Acoustic cement metering equipment is an eight-sectored scanning multi-frequency ACC8CM device which is used for selection of vertical channels in wells between the column and cement stone, cement stone and formation with disclosure of at least 15 degrees in oil and gas wells. The analysis of the dynamic parameters of the target waves makes it possible to reveal the character of the contact and to identify the intervals of poor cementing of the casing string. This device provides registration of acoustic wave fields excited by a monopole emitter.
The scope of the equipment is research by the method of wave acoustic logging of cased wells with a diameter from 125 to 300 mm at the upper values of the ambient temperature of 120oC and hydrostatic pressure of 80 MPa with a well inclination angle of no more than 35oC, at a logging speed of up to 280 m/h.

Key words:

casing string, cement stone, acoustic cement metering, contact, estimation of quality
