Reserves exploitation degree is low, development effectiveness is poor thoroughly.There is water injection well and open in waterflood development of low-permeability reservoirs
Dynamic pressure is high, injection pressure rises soon, water absorbing capacity declines to a great extent, producing well yield declines fast
Etc. problem, recovery ratio is the highest；And for bottom water low-permeability oil deposit, in development process not only
There is low permeability flow, there is also bottom water coning phenomenon, this has a strong impact on development effectiveness.Opening
Send out in bottom water low-permeability oil deposit, selection development scheme (straight well or horizontal well development) that holds water,
The deployed position etc. of new well, it is possible to slow down or avoid the outstanding problem in exploitation, improving oil reservoir
Recovery ratio, it is thus achieved that bigger economic benefit.
In Patents at home and abroad, manufacturing more for Thief zone scale-model investigation, China is specially
The analoging detecting device of profit document 200520000431.4 oil saturation field, this model is to fill out
Sand, Thief zone model, do not account for the situation of hyposmosis；New well deployed position is not accounted for yet
With different development schemes on oil recovery, the impact of remaining oil saturation distribution.
The bottom water coning rule of bottom water reservoir is carried out physical modeling, has answered
With.Physical model for bottom water reservoir exploitation is more the most both at home and abroad, but existing model
Certain gap is there is in design to oil field, the particularly similarity of offshore oilfield completion method；Existing
Model experiment to bottom water coning phenomenon, and effective control measure that different development phases is taked
Modelling lacks preferable method.
