Description

用于控制加压流体在管道中输送的设备及控制原动机的方法
技术领域
本发明涉及如分别由权利要求1和6中的前序部分所述的控制原动机的方法以及相关的设备，该原动机配置成驱动一个或更多个流体输送***以输送管道中的流体。本发明在借助于油井增产工艺的压力泵送设备来提取页岩油和/或燃气中是特别有用的，该操作通常被称为“液压压裂”或“压裂”，但本发明不限于这种操作。
背景技术
数十年来，用于压力泵送的大部分设备遵循如下相同的原则：拖车或卡车上安装的动力组(柴油驱动的往复式发动机或燃气涡轮发动机)通过多速变速器齿轮箱来驱动压力泵。所有部分都是机械连接的。
典型的压力泵包括两个主要部分：“流体端部”和“动力端部”。流体端部是对压裂流体进行加压的实际的压力泵。其通常是柱塞泵/活塞泵，通常以每分钟150至300次冲程运行，并且是可替换的单元。动力端部是动力传动***的一部分，并且该动力端部连接至多速变速器。动力端部在入口上具有减速齿轮箱，并且借助于曲轴和十字结联轴节连接至流体端部上的柱塞。尽管也使用燃气涡轮发动机，但通常由往复式发动机提供动力。
与现有技术相关的一些问题在于缩短了设备的预期寿命周期，以及在动力传动***的寿命周期期间的高维护成本。此外，现有技术的设备具有大的表面占有空间。
现有技术包括CN 104806220 A，其描述了具有动力单元和压裂泵的“全液压驱动”压裂设备。动力单元包括发动机单元、分动箱单元和液压泵单元。每个分动箱上安装有三个液压泵，并且液压泵单元借助于液压管线而连接。压裂泵包括左泵头和右泵头；三个并联布置的双向液压油缸安装在压裂泵上。压裂泵由双向液压油缸驱动，使得设备功率提高、设备排出流量增加；设备重量及尺寸减少。
现有技术还包括CN 104727797 A和CN 204552723 U，其描述了发动机、分动箱、多个可变排量的柱塞泵和双作用压裂泵布置在底盘上的一种***。发动机的输出端部与分动箱的输入端部连接，并且分动箱的输出端部包括多个动力输出端口。每个动力输出端口与一个可变排量的柱塞泵连接。柱塞泵通借助于液压***驱动双作用压裂泵。
现有技术还包括CN 104728208 A，其描述了一种高功率液压驱动压裂泵泵站***，其中液压缸与压裂缸连接。电动马达驱动的液压泵提供高压油并且流体出口歧管输出高压压裂流体。
现有技术还包括CN 104453825 A，其描述了包括动力单元和压裂泵单元的模块化压裂泵组。辅助发动机布置在动力单元上并连接至液压泵。变矩器布置在压裂泵中，并且变矩器的输入端部连接至主发动机。变矩器的输出端部连接至齿轮箱，并且齿轮箱的输出端部连接至压裂泵。
现有技术还包括WO 2014/078236 A1，其描述了一种涡轮轴发动机，该涡轮轴发动机具有驱动轴和联接至驱动轴的高压高转速离心泵。
发明内容
在独立权利要求中阐述并描述了本发明，而从属权利要求描述了本发明的其他特征。
因此，提供了一种控制原动机的方法，该原动机配置成驱动一个或更多个正排量流体输送***以在管道中输送流体，其特征在于，感测管道中的流体中的压力变化，并且基于所感测的压力变化控制所述正排量流体输送***中的至少一个并控制原动机的动力输出。
该方法还可以包括确定预估的动力消耗。在一个实施方式中，该方法包括通过感测的压力变化来控制原动机燃料供应。可以基于由操作者或整体控制***确认和设定的设定点(速率/压力)来控制所述至少一个正排量流体输送***。
在一个实施方式中，第一控制器可以向液压泵提供控制信号，液压泵配置成操作所述流体输送***并由原动机驱动，由此基于感测的管道中的压力变化来控制液压泵与原动机之间的相互作用。
还提供了用于控制加压流体在管道中的输送的设备，其特征在于，原动机，其配置成向一个或更多个液压泵供应转矩，每个液压泵配置成向相应的正排量流体输送***供应液压压力，每个正排量流体输送***配置成输送管道中的所述流体，
-第一感测装置，其配置成用于感测管道中的压力变化并且连接至第一控制器；第一控制器配置成向至少一个流体输送***的控制阀和原动机的控制***提供控制信号。
该设备可以包括一个或更多个液压泵，液压泵配置成与控制装置连通，并且液压泵配置成操作所述流体输送***并由原动机驱动，由此基于感测的管道中的压力变化来控制液压泵与原动机之间的相互作用。
在一个实施方式中，设备还包括连接至相应的控制阀的阀出口反馈压力传感器以及连接至控制阀的阀入口压力传感器。该设备还可以包括阀控制器，该阀控制器配置成接收来自压力传感器和第一感测装置的信号、来自正排量流体输送***的位置反馈，并且该阀控制器配置成向控制阀提供控制信号。
在一个实施方式中，原动机可以是燃气涡轮发动机。齿轮单元可以布置在燃气涡轮发动机与液压泵之间。在一个实施方式中，原动机是往复式发动机。所述至少一个正排量流体输送***可以包括正排量泵。
本发明的设备可以设置在例如拖车的移动单元上。
尽管本发明在液压压裂的(“压裂”)操作中特别有用，但其也适用于基于流量和压力设定的反馈压力来控制的所有正排量泵送过程。因此，本发明不限于压裂操作。
附图说明
参照所附的示意图，从作为非限制性示例给出的实施方式的以下描述中，本发明的这些特征和其他特征将变得清楚，其中：
图1是示出本发明设备的典型构造并图示本发明的原理的流程图；
图2是处于运输构型的用于本发明的设备的移动单元的实施方式的立体图；
图3是图2中所示的移动单元的立体图，并且图示了处于泵送(操作)构型的设备；以及
图4是图3中所示的移动单元的立体图，但是其中移除了外壳以图示本设备。
具体实施方式
以下描述可以使用比如“水平”、“竖向”、“横向”、“来回”、“上下”、“上”、“下”、“内”、“外”、“前”、“后”等的术语。这些术语通常指的是如附图中所示并且与本发明的正常使用相关联的视图和取向。这些术语仅用于使读者方便，而不应是限制性的。
首先参照图2、图3和图4，本发明的设备在该图示的实施方式中布置为位于拖车19上的移动单元18并由外壳20封闭。外壳中的门提供通向设备的入口，并且后门允许可移动单元在设备运行时向外和向下移动(见图3)，可移动单元包括具有其双作用缸22的流体端部21。管21a配置成用于连接至井管(未示出)。
参照图4，在图示实施方式中移动设备包括：燃气涡轮机26，该燃气涡轮机26经由导管27a连接至空气入口27；以及排出开口26a。燃气涡轮机接纳来自燃料箱32的燃料。由于供应线和软管、动力线以及控制线等这些部件在本领域中是公知的，因此未示出。
燃气轮机26经由齿轮箱28连接至一组单个或串联安装的液压泵30。附图标记31和29分别表示液压箱和蓄能器箱。通风窗和空气过滤容器23布置成朝向移动单元的后方、位于油冷却器齿轮箱25和液压装置24后面。
液压泵30操作设备的流体端部21中的双作用缸22。每个液压缸操作位于设备的两个流体端部中的一者中的一个柱塞。
现在将参照图1中的流程图描述示出了本发明原理的本发明的设备的典型构造。
在图1中示出了分别指示为A、B、C的三个***。应当理解的是，为了说明清楚，在图1中仅详细地示出了***C。技术人员将理解的是，参照***C说明和描述的部件和功能也可以应用于***A和B。还应当理解的是，本发明不应限于图1中所示的***的数量。
附图标记1指示动力源，该动力源包括原动机2。原动机可以是燃气涡轮发动机或往复式发动机，其经由(控制燃料供应F并接收关于转速R的信息的)节流阀3控制。原动机2连接至齿轮单元8并且配置成将转矩T传递至齿轮单元8。齿轮单元8将转矩T’传递至各个液压泵9a至9c；每个泵具有相应的泵压力传感器13a至13c。
如果原动机2是燃气涡轮机，则齿轮单元8可以配置成减少来自涡轮机的高转速输出。如果原动机是另一种类型的发动机(例如往复式发动机)，则液压泵可以由发动机直接驱动，并且可以省略齿轮单元8。
每个液压泵9a至9c经由相应的控制阀36a至36c、37a至37c向相应的正排量流体输送***供应液压，正排量流体输送***在图示实施方式中为双作用液压缸34a至34c。储液罐11和冷却器17流体连接在液压泵9c与控制阀36c、37c之间。该回路还包括用于减轻压力脉冲的蓄能器33。
每个液压缸34a至34c驱动地连接至各组流体柱塞35a1至35c1、35a2至35c2。流体柱塞35a1至35c1、35a2至35c2经由流体供应线10向井供应流体。然而，本发明不限于这种流体柱塞。附图标记12指示来自流体混合***(未示出)的抽吸线。
井反馈压力传感器16连接至供应线10并且配置成感测供应线10中的压力(并因此感测压力变化)。阀出口反馈压力传感器15连接至相应的控制阀36c、37c。阀入口压力传感器14连接到控制阀36c。阀控制器7(通常是可编程逻辑控制器-PLC)接收来自压力传感器14、15、16的信号、来自液压缸的位置反馈Cp，并将控制信号Vf提供至控制阀36c、37c。
主控制***4基于动力需求Pr控制节流阀3并提供动力反馈Pf。主控制***4还接收来自齿轮单元8的运输安全联锁反馈Ts和来自PLC 7的基于由井反馈压力传感器16感测到的压力变化而预估的动力消耗数据EPC。通风窗控制器5也与主控制***4连通，以打开及关闭通风窗(例如用于通风和消防)。主控制***4接收来自液压泵控制器6(例如PLC)的数据并向液压泵控制器6提供动力指令Ac。液压泵控制器6进而基于(来自压力传感器13c的)泵压力反馈Pp向液压泵9c提供所需的排量指令Dc。主控制***4还向阀控制器7提供关于所需的缸速度RCS的数据，该阀控制器7进而如上所述确定阀流量控制信号Vf并向控制阀36c、37c提供阀流量控制信号Vf。
因此，本发明包括液压/流量控制的动力传动装置，其中来自原动机的所有动力通过液压泵转换成液压动力。液压泵使原动机能够在克服很小或没有负载的情况下启动。
当设备用于压裂操作中时，原动机2和液压泵9a至9c操作液压缸34a至34c和流体柱塞35a1至35c1、35a2至35c2以将加压的压裂流体供应至线10(并且因此供应至地下井)。井中产生的液压压裂压力是井压力和由柱塞产生的液压压力的结果。(由传感器16感测的)井压力被传送至阀控制器PLC 7，该阀控制器PLC 7控制控制阀36a至36c、37a至37c并且还确定被传输至主控制***4的预估动力消耗EPC。原动机燃料供应(例如，涡轮机燃料喷射)因此可以由井压力控制，或者更确切地说由通过传感器16连续感测的压力变化控制。燃烧涡轮机燃料控制器接收来自液压控制***的基于来自液压压裂压力的压力和速率读数的压力读数。然后，液压控制***基于由操作员确认和设定的设定点(速率/压力)执行控制动作。
液压部件中固有的“延迟”或者由主控制***4控制的“延迟”为涡轮机燃料控制器提供足够的时间以“预测”将要发生的事情，并在其发生之前采取行动。
这意味着原动机能够在需求出现之前增加燃料喷射(打开节流阀)以为来自液压泵的更高要求做准备，或者降低燃料喷射(限制节流阀)以适应预估的未来需要的转矩，从而适应速率/压力的变化。该功能在原动机是燃气涡轮发动机的实施方式中尤其有用，这是因为这种涡轮机通常在高转速下运行并且具有低转矩。控制***可以以这种方式防止燃气涡轮发动机过速，并且进一步使得燃气涡轮发动机在预测的增加的转矩需求中具有优势(head start)。
当井中压裂流体的需求发生变化或者压裂流体的实际消耗发生变化且与由操作者设定或由整体控制***确定的设定点不相符时，阀控制器7和压力传感器16基于感测到的压力变化感测这种情况。设定点还可以基于由整体控制***规定的如何处理偏离条件的优先处理表来限定。基于设定点与(如由16感测的)实际压力读数之间的速率/压力差，将出现(由泵控制器6馈送至主控制器4的)实际动力指令Ac与预估的动力消耗EPC(其由阀控制器7馈送至主控制器4)不同(小于或大于)的情况。这将导致下述情况：主控制器4将能够将控制信号给出至泵控制器6和原动机节流阀控制器3，并且能够将给出至泵控制器6和原动机节流阀控制器3的控制信号的时刻控制为同时的或者具有受控的差异，从而实现使原动机以预测的方式运行。
尽管已经参照三个液压泵描述了本发明，但是应当理解的是，本发明同样适用于更少或更多个液压泵。
尽管已经参照移动单元描述了本发明，但是应当理解的是，本发明同样适用于固定设备。
尽管已经参照驱动流体端部(双作用液压缸)描述了本发明，但是应当理解的是，本发明同样适用于由液压流和压力驱动的其他泵送原理，即正排量泵。因此，本发明应当不限于双作用液压缸。
