Description
Technical field
The utility model belongs to offshore oil exploitation technical field, and particularly one provides offshore oilfield integrated acidification to dispel block application system.
Background technology
Offshore oilfield is different with onshore oil field, and its platform space is narrow.If platform beats new well or pump detection and workover, other work measure can not be implemented.Cause injection pressure to raise because well injects sewage quality defective (oil-containing, machine are mixed and particle diameter exceeds standard), when close to formation fracture pressure, must injection rate be reduced, thus affect waterflooding development effect.Adopt acidification to dispel block measure for this reason, reduce note pressure, reach injection allocation amount.Because of platform restriction, acidification to dispel block is constructed on general tugboat ship and is constructed, and tugboat (400T) conventional acidulation technique is: tugboat is stopped near operation platform, and institute's with medicament is extracted into different surge tank (30-40m
3), then be diluted to design concentration with injection water, clamp-on construction well with acidifying high-pressure pump.Tugboat (400T) discharging only can be constructed a bite well, and its cost is quite large, and efficiency of construction is low.In order to reduce costs, improve and execute speed, need develop a kind of integrated acidifying and supporting corresponding construction skill, each tugboat (400T) discharging only can be constructed more than 6 mouthfuls of wells, greatly improves efficiency of construction, and after its construction, effect does not subtract.
Utility model content
The utility model object is the weak point for overcoming prior art, proposes the integrated acidification to dispel block application system of a kind of offshore oilfield.Current tugboat (400T) acidizing unit can be utilized, once go out the material of more than 6 mouthfuls of wells.During construction, need not dilute after medicament is extracted into different surge tank, directly well head high pressure mixer clamp-oned by acidifying high-pressure pump on the one hand, and another aspect platform high-pressure injected water also enters well head high pressure mixer and evenly dilutes, and evenly dilution acid solution enters de-plugging target zone.
The one that the utility model proposes provides offshore oilfield integrated acidification to dispel block application system, it is characterized in that, this system comprises and forms acid solution injected system by surge tank, acidifying high-pressure pump, online wireless transmission flow meter, well head high pressure mixer; Acid dilution system is formed by high-pressure injected water pump, online wireless receiving control metering device, well head high pressure mixer; By online wireless transmission flow meter, online wireless receiving controls metering device and forms online dilution proportion system; Wherein, surge tank, acidifying high-pressure pump, online wireless transmission flow meter, well head high pressure mixer are connected successively; High-pressure injected water pump controls metering device by online wireless receiving and is connected with well head high pressure mixer, and online wireless transmission flow meter and online wireless receiving control metering device and be connected.
The utility model proposes one provides integrated its advantage of acidification to dispel block application system of offshore oilfield to be:
Utilize current tugboat (400T) conventional acidulation equipment, realize a discharging 6 mouthfuls of above acidification to dispel block of well;
Inject water at the scene to mix with acid solution, do not conflict with offshore production platform water filling flow process;
The high pressure mixer of this cover system is arranged in well head, without any safety factor;
This cover system efficiency of construction is high, and effect is not second to conventional acidulation de-plugging;
This system cloud gray model is simple to operate.
