METHOD OF HORIZONTAL WELL OPERATION

摘要

FIELD: mining. ^ SUBSTANCE: flush-joint pipe of koltubing is installed inside flow column. The end of the koltubing pipe is placed in the end of a horizontal bare hole. By means of circulation a high viscosity hydrophilic solution at a volume of 0.1-0.3 of a borehole length is pumped into the horizontal borehole via the flush-joint pipe of the koltubing; then a process solution at a volume of the horizontal borehole in a payout bed is pumped. At that at process solution pumping, the flush-joint pipe of the koltubing is raised at a rate of filling the horizontal borehole of well with the process solution. Process conditioning is carried out for process solution reaction. The well is then developed, and further operation is performed at minimal loads to the well during the first 10-15 days. ^ EFFECT: upgraded efficiency of horizontal well. ^ 1 ex
