Abstract
The invention discloses a water distribution system applied to oilfield exploitation. The water distribution system applied to the oilfield exploitation is mainly composed of a water injection station, a water distribution chamber and a water injection well. The water injection station is connected with a water source, the water distribution chamber is connected with the water injection station, and the water injection well is connected with the water distribution chamber. The invention further discloses a water distribution method based on the water distribution system. The water distribution system facilitates stratification testing and is suitable for a rank water injection developing block which is big in oilfield area, multiple in water injection wells and big in water injection amount.
Description
Technical field
The present invention relates to a kind of water distribution system and decreasing water distribution method thereof that is applied to oilfield exploitation.
Background technology
Water filling is a kind of very important mining type in oil field development, and it can replenish stratum energy effectively, improving oil recovery factor, guarantees to have played positive role in oil field high yield, stable yields.But water filling itself is also an energy consumption rich and influential family, and the power consumption of flood pattern is huge, accounts for 33%～56% of China's field produces electricity consumption.And along with the rising water injecting consumption of oil field composite water cut also will sharply rise.Therefore, the energy-saving and cost-reducing of flood pattern has great importance for reducing the field produces cost.Add up according to investigations, China's water injecting pump operational efficiency average out to 75.2%, domestic advanced value is 79.9% (grand celebration), is abroad 80%～85%.Domestic water filling electricity consumption unit consumption average out to 6.94kWh/t, advanced value for 6.15kWh/t, is abroad 5.6～6.0kWh/t.The average Water Injection Efficiency in the whole nation is 47.8%.This shows, improve Water Injection Efficiency, energy-saving and cost-reducing, have great significance.
Water Injection Efficiency is the index of a reflection oil field flood pattern ground surface works comprehensive economy technology, and the height of Water Injection Efficiency directly affects the height of cost of crude oil production.Development along with the development technology in oilfield technology, each oil field, the whole nation has begun to take shape the Above Ground Technology that satisfies the water flooding needs that is fit to this oil field all kinds oil reservoir, different injection pressure, different quality characteristics on flood pattern, for good condition has been created in stable yields, the volume increase in oil field.But along with the increase of oil field development difficulty, the Water Injection Efficiency in most of oil field does not all reach standard-required.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, a kind of water distribution system that is applied to oilfield exploitation is provided, this water distribution system zonal testing that is applied to oilfield exploitation is convenient, is applicable to the line drive water injection development block that the oil field area is large, water injection well is many, water injection rate is larger.
Another object of the present invention has been to provide a kind of decreasing water distribution method based on above-mentioned water distribution system.
Purpose of the present invention is achieved through the following technical solutions: the water distribution system that is applied to oilfield exploitation, mainly consisted of by water-injection station, distributing room for water injection and a water injection well, described water-injection station is connected with the water source, and distributing room for water injection is connected with water-injection station, and water injection well is connected with distributing room for water injection.
Described distributing room for water injection is connected with water-injection station by a water filling main line.
Described distributing room for water injection is provided with the water distribution loop.
Described water distribution is provided with flow meter on the loop.
Decreasing water distribution method based on above-mentioned water distribution system is characterized in that, comprises the following steps:
(a) at first, by after flow meter, enter water-injection station from the water at water source;
(b) then, after entering water in water-injection station and carrying out supercharging, enter the distribution pipe of distributing room for water injection by the water filling main line;
(c) according to the actual requirements, by the water distribution loop, the water that enters in distribution pipe is regulated, finally completed water distribution in the water injection well.
In sum, the invention has the beneficial effects as follows: zonal testing is convenient, is applicable to the line drive water injection development block that the oil field area is large, water injection well is many, water injection rate is larger.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited only to this.
Embodiment:
As shown in Figure 1, the water distribution system that is applied to oilfield exploitation that the present invention relates to mainly is made of water-injection station, distributing room for water injection and a water injection well, and described water-injection station is connected with the water source, and distributing room for water injection is connected with water-injection station, and water injection well is connected with distributing room for water injection.
Described distributing room for water injection is connected with water-injection station by a water filling main line.
Described distributing room for water injection is provided with the water distribution loop.
Described water distribution is provided with flow meter on the loop.
Decreasing water distribution method based on above-mentioned water distribution system comprises the following steps:
(a) at first, by after flow meter, enter water-injection station from the water at water source;
(b) then, after entering water in water-injection station and carrying out supercharging, enter the distribution pipe of distributing room for water injection by the water filling main line;
(c) according to the actual requirements, by the water distribution loop, the water that enters in distribution pipe is regulated, finally completed water distribution in the water injection well.
To sum up, the present invention is convenient to adjust injection pipe network, and distributing room for water injection can be unified with the oil gas metering station, is convenient to management.This flow process is applicable to that the oil field area is large, and water injection well is many, the block of the large tracts of land waterflooding extraction that water injection rate is large.
The above is only preferred embodiment of the present invention, is not the present invention is done any pro forma restriction, and every foundation technical spirit of the present invention, any simple modification, equivalent variations that above embodiment is done are within all falling into protection scope of the present invention.
