Cement grouting is fed in portions of drilling mud, water and mud again with installation of cement grouting in annular space above stage cementing collar, and water portions in column in interval of cement collar of stage cementing. Hardening of cement of first stage is waited for. Drilling mud is circulated in cyclic mode via column through cement collar of stage cementing with output on head through annular space until complete removal of cement grouting in interval of cement collar of stage cementing. Cementing of second stage is carried out. That is ensured by pumping via column a portion of buffer solution and design volume of cement grouting. Upper plug is placed and flushed by process water. Pressure in string is increased above working pressure while pumping until closure of holes of cementing collar of stage cementing. Cementing hardening is waited for.
