As shown in Fig. 2, the present invention provides a kind of determination method of stratified reservoir lower-continuous mapping, include the following steps:
S1: the geology connection panel map of oil reservoir is obtained.
S2: panel map is connected to according to the geology and determines at least one first object oil reservoir according to the first pre-defined rule.

State the theoretical percent inspiration that each oil reservoir is obtained in first object oil reservoir.
S5: according to the theoretical percent inspiration of each oil reservoir according to third pre-defined rule to the oil well pump it is initial under
Pump depth is adjusted to obtain the target lower-continuous mapping of oil well pump.
In the present embodiment, the geology for obtaining oil reservoir first is connected to panel map, for example, Fig. 1 shows the ground of certain oil reservoir
Matter is connected to panel map, as shown in Figure 1,2#Well is injection well, 1#Well is producing well.Panel map is connected to according to the according to above-mentioned geology
One pre-defined rule determines at least one first object oil reservoir.Wherein, the first pre-defined rule is that can connect self seeding well to producing well
Logical oil reservoir is determined as first object oil reservoir.That is, picking out self seeding well to producing well in geology connection panel map
The oil reservoir that can be connected to, using these oil reservoirs as first object oil reservoir.The first object oil reservoir can be multiple.
Then, determine that the initial lower pump of oil well pump is deep according to the second pre-defined rule according at least one first object oil reservoir
Degree.Wherein, the second pre-defined rule is by oil well pump tripping in close to the lower section of the first object oil reservoir in shaft bottom.That is, determining
After first object oil reservoir, by the multiple first object oil reservoirs of oil well pump tripping under the first object oil reservoir in shaft bottom
This position, is determined as the initial lower-continuous mapping of oil well pump by side.Specifically, it is contemplated that the viscous crude effect of oil well pump can will take out
Oil pump tripping in is at the 3-5 rice of the lower section of the first object oil reservoir in shaft bottom.

Pump depth just has having a certain impact.Since the hot exhaust gas that fireflood oil reservoir generates would generally move up.If therefore in producing well
Oil well pump be located at the generating layer position of hot exhaust gas or the top of hot exhaust gas generating layer position, then the oil well pump in producing well is likely to
It aspirates hot exhaust gas and generates vapour lock, and then will have a direct impact on the pump efficiency of oil well pump.So by the oil well pump tripping in producing well
Near the lower section of the second seed oil layer in shaft bottom.Specifically, it is contemplated that the viscous crude effect of oil well pump, it can be by oil well pump tripping in most
At the 3-5 rice of the lower section of the second seed oil layer in shaft bottom.
