Description
Technical field
The utility model relates to a kind of offshore oil exploitation water filling collective and distributive type control system.
Background technology
Makeup energy is come owing to geogen causes oil field development must be based on water filling in the oil field in zone, the Bohai Sea.Early field life owing to there are not enough oily waters, can only take the mode of seawater injection, but the fresh water ratio is large in the near Bohai Sea seawater, and water quality is complicated, and seawater injection becomes problems of concern to the injury of oil reservoir.In oil field development mid-term, oil field produced composite water cut reaches 40%, and this part oily water does not exist and the stratum problem that is incompatible, as long as the indexs such as suspension content, grain diameter, oil content are handled well, can be used as the water filling water source.At present, the oily water produced quantity is not enough to satisfy whole oil-field flooding requirement, must replenish the part seawater.Therefore how effectively to adjust water injection rate, realizing recovering the oil with the dynamic equilibrium that mixes water filling is the problem that current needs solve.
The utility model content
The purpose of this utility model is exactly for addressing the above problem, a kind of offshore oil exploitation water filling collective and distributive type control system is provided, it is by the Import computer control technology, pass through ethernet communication, realize mixing the automatic operating configuration of flood pattern, so that recover the oil and mix water filling and reach dynamic equilibrium, improved output.
For achieving the above object, the utility model adopts following technical scheme:
A kind of offshore oil exploitation water filling collective and distributive type control system, it comprises seawater treatment apparatus and wet crude treating apparatus two parts, wherein seawater treatment apparatus comprises seawater lift pump, it is connected with coarse filter, coarse filter is connected with the seawater subsider, the seawater subsider is connected with fine cleaner, and fine cleaner is connected with oxygen remove; The wet crude treating apparatus comprises three phase separator, and three phase separator is connected with Water Tank, and Water Tank is connected with sewage pump, and sewage pump is connected with hydrocyclone, and hydrocyclone is connected with strainer; Strainer is connected with distribution pipe with oxygen remove, and distribution pipe is connected with water injection tank, and water injection tank then is connected with water injecting pump; Seawater lift pump, sewage pump and water injecting pump are respectively equipped with corresponding flow transmitter, each flow transmitter is communicated by letter with host computer by Ethernet, host computer simultaneously also be arranged on seawater lift pump, sewage pump and water injecting pump exit and be connected corresponding electric control valve and be connected.
The sump oil that described three phase separator, hydrocyclone and strainer separate is sent into contaminated oil pipe.
The utility model can real-time monitoring system operational factor, guarantee the recovery that can be saved of stratum energy, improved output, have the characteristics such as reliability height, workable, easy maintenance, brought good economic benefit and social benefit to enterprise.
