It is: firstly, obtaining the permeability and effective thickness of each oil reservoir；Then, by a permeability for oil reservoir and multiplying for effective thickness
Formation capacity of the product as the oil reservoir；Finally, by the ratio of the sum of the formation capacity of the formation capacity of the oil reservoir and each oil reservoir
Value splits score value on the oil reservoir as water injection rate, thus, determine water injection rate in vertical direction split a point ratio.Due to water filling
Amount to split point result not only related with the permeability of oil reservoir and effective thickness, it is also related with dynamic parameter, for example, oil reservoir is aqueous
The moisture content etc. of certain depth in saturation degree, producing well, so splitting water filling determined by point method using existing formation capacity
The accuracy for splitting point result of amount may be lower.
