水下增压泵在水下生产系统中的使用

发布时间:2023-05-31 09:46:30   发布人:http://www.booklovinmamas.com
水下生产系统通常依靠自身压力进行开采。而对于某些少数水下生产系统,需要借助注水/注气或采用水下增压泵以保持系统压力。开发某些水下生产系统,其存在水深较深、重稠油、油藏储量小、储量不明或低采收率、流体低压/极高压、流动保障要求、回接距离远、一期增压泵成熟使用等情况,可考虑采用放置在海床上的水下增压泵进行开发。采用水下增压泵进行油气开发,可有效增加采收率,促进生产,简化上部平台等基础设施。
Underwater production systems typically rely on their own pressure for extraction. For some few underwater production systems, it is necessary to use water/gas injection or underwater booster pumps to maintain system pressure. Developing certain underwater production systems with deep water depth, heavy heavy oil, small reservoir reserves, unknown reserves or low recovery rates, low/extremely high fluid pressure, flow guarantee requirements, long return distance, and mature use of Phase I booster pumps can consider using underwater booster pumps placed on the seabed for development. The use of underwater booster pumps for oil and gas development can effectively increase oil recovery, promote production, and simplify infrastructure such as upper platforms.
水下增压泵在水下生产系统中的应用
The Application of Underwater Booster Pump in Underwater Production System
某油田水下生产系统包括3口水下采油树,水深约500米,油气产出物回接至某上部海上平台。采用水下生产系统开发方案,采用水下增压泵举升的采油方式,可实现油田的高速开发,提高采收率。某油田地质油藏特征表明,砂岩油藏物性好、产能高、地层能量充沛,利用地层能量将流体举升至海底,再利用增压泵进行开采。
The underwater production system of a certain oilfield includes three underwater Christmas trees, with a water depth of about 500 meters. The oil and gas production is connected back to an upper offshore platform. The use of an underwater production system development plan and the use of an underwater booster pump lifting oil extraction method can achieve high-speed and efficient development of the oil field and improve oil recovery. The geological reservoir characteristics of a certain oilfield indicate that sandstone reservoirs have good physical properties, high production capacity, and abundant formation energy. The formation energy is used to lift the fluid to the seabed, and then a booster pump is used for production.
水下增压泵总体要求:
Overall requirements for underwater booster pumps:
水下增压泵系统包括集成在水下管汇上的水下增压泵模块、布置在上部平台上的增压泵的相关动力和控制设备,包括MCS,EPU,VFD,HPU,BPU(隔离液单元)等。以及脐带缆中与增压泵相关的组成部分,增压泵操作、安装、回收专用工具等。
The underwater booster pump system includes an integrated underwater booster pump module on the underwater manifold, and the related power and control equipment of the booster pump arranged on the upper platform, including MCS, EPU, VFD, HPU, BPU (isolation fluid unit), etc. And the components related to the booster pump in the umbilical cable, as well as the special tools for operating, installing, and recycling the booster pump.
水下增压泵模块集成在水下管汇上,水下增压泵模块设计为可回收形式,可提升至水面上进行维修,并使用ROV进行连接和解脱。水下增压泵应设计适应水深。根据某油田现在油藏配产和操作条件,增压泵输送过程中不会出现气体,水下增压泵采用单相泵。单相泵能够适应的GVF(gas volume fraction)范围为0~10%。
The underwater booster pump module is integrated on the underwater manifold, and is designed as a recyclable form that can be lifted to the surface for maintenance, and connected and disengaged using ROV. The underwater booster pump should be designed to adapt to water depth. According to the current production allocation and operating conditions of a certain oil field, gas will not appear during the transportation process of the booster pump, and the underwater booster pump adopts a single-phase pump. The range of GVF (gas volume fraction) that single-phase pumps can adapt to is 0-10%.
在水下增压泵维护方面,应了解增压泵的水下维护空间、安装维修工具等需求,将在设计中予以体现。
In terms of underwater booster pump maintenance, it is necessary to understand the underwater maintenance space, installation and repair tools, and other requirements of the booster pump, which will be reflected in the design.
气体增压泵
水下增压泵模块设计:
Design of underwater booster pump module:
某油田增压泵模块的尺寸约为4mX3.5mX6m,重量约为50吨。水下整个增压泵模块包括泵体、马达箱、泵工艺管线接口、控制接口/隔离液接口/HIGH VOLTAGE接口的ROV操作面板的模块结构。
The size of the booster pump module in a certain oilfield is about 4mX3.5mX6m, and the weight is about 50 tons. The entire underwater booster pump module includes the module structure of the ROV operation panel, including the pump body, gearbox, pump process pipeline interface, control interface/isolation liquid interface/HIGH VOLTAGE interface.
水下增压泵采用立式泵,泵轴和马达竖直安装,马达箱位于泵体上方。马达配置上部组块上的VFD,以满足水下增压泵设计年限内的各种工况。
The underwater booster pump adopts a vertical pump, with the pump shaft and motor installed vertically, and the motor box located above the pump body. The motor is equipped with VFD on the upper module to meet various operating conditions within the design life of the underwater booster pump.
水下增压泵的工艺进出口管线接口位于泵体正下方,增压泵进出口管线采用水下垂直连接器与管汇上管线接口进行快速精准连接,同时方便提升水下增压泵时与管汇上管线解脱。
The process inlet and outlet pipeline interface of the underwater booster pump is located directly below the pump body. The inlet and outlet pipelines of the booster pump use underwater vertical connectors to quickly and accurately connect with the pipeline interface on the manifold, while facilitating the disconnection from the pipeline on the manifold when lifting the underwater booster pump.
水下增压泵ROV操作面板全部设置同一面上,以方便ROV水下连接及操作。操作面板包括控制电飞线、液压飞线(包括液压/化学药剂)、隔离液飞线、HIGH VOLTAGE飞线等接口。
The ROV operation panels of the underwater booster pump are all set on the same side to facilitate underwater connection and operation of the ROV. The operation panel includes interfaces such as control electric flying wires, hydraulic flying wires (including hydraulic/chemical agents), isolation liquid flying wires, and HIGH VOLTAGE flying wires.
水下增压泵ROV操作面板一侧的管汇保护罩为敞开式设计,而其它3面均可设计为用保护罩进行保护,以极大限度地保护管汇内部设施和泵体。增压泵设置ROV操作抓手,ROV操作面板应方便ROV连接及操作,应位于1.5米泥线以上,并且需要考虑ROV操作空间。
The manifold protection cover on one side of the ROV operation panel of the underwater booster pump is designed to be open, while the other three sides can be designed to be protected with protective covers to greatly protect the internal facilities and pump body of the manifold. The booster pump should be equipped with an ROV operating handle, and the ROV operating panel should be convenient for ROV connection and operation. It should be located above the 1.5 meter mud line and need to consider the ROV operating space.
水下增压泵顶部设有吊耳,由于水下增压泵维修时需要提升,应在泵体上方的管汇保护罩上设置顶部开门,实现泵体提升及保护泵体的作用。水下增压泵模块设置导向杆。
The top of the underwater booster pump is equipped with lifting eyes. Due to the need for lifting during maintenance of the underwater booster pump, a top door should be installed on the protective cover of the manifold above the pump body to achieve the function of lifting and protecting the pump body. The underwater booster pump module is equipped with a guide rod.
