In the development of massive oil pool of normal cyclothem with sufficient reservoir energy and active edge and bottom water drive, the primary means of controlling the appearance of secondary bottom water and the intervention of water coning is to perforate only the upper part of the reservoir at limited interval so as to prolong the period of production and increase the amount of output without water cut.

This study shows that the bottom-water ventilation was relatively stronger during the postglacial period than during the glacial and deglaciation periods, which is indicated by the oxygen concentration of bottom-water and the changes of microfossil assemblages.

Horizontal well; bottom water reservoir; perforated completion; horizontal wellhole pressure drop; bottom water coning

水平井男人的天堂网免费网站；底水油藏；射孔完井久久九九re精品国产三级；水平段壓降；臨界壓力

The pressure drop along the horizontal wellhole was combined with the critical pressure drop of the bottom water-driven reservoirs, thus the relation between the critical pressure and the critical flow rate when the horizontal well originally put into production was researched,which provide a reference for the design.of the deliverability of the horizontal well used in the bottom water reservoir existing the bottom water coning.

However, the water quality simulation results by CE-QUAL-W2 model revealed that the hydrologically induced density currents in winter together with the external loads of P were the main cause of the surface water quality deterioration, even though the bottom water carrying abundant P internal loads might be lifted to the middle layer by the water momentum force by the density current.

New methods for preventing and treating bottom water coning are found out through deeper understanding of the development practice and rational adjustment, which are to control liquid production in low water cut period, to produce oil and water simultaneously in medium water cut period, and to drill side - track well or to shut well down to kill coning in high water cut period.
