通过上述附图，已示出本申请明确的实施例，后文中将有更详细的描述。这些附图和文字描述并不是为了通过任何方式限制本申请构思的范围，而是通过参考特定实施例为本领域技术人员说明本申请的概念。
具体实施方式
首先，目前针对酸化压裂工艺参数优化实验评价大多采用三轴压缩后的岩石样品，开展导流能力、水力裂缝或酸蚀裂缝形态研究，多个研究分开进行。但是，岩石样品在压缩后再进行下一次实验过程中的应力加载或卸载后会产生损伤，裂缝的开度以及摩擦系数等都会受到很大的影响。相关装置在实时获取岩石样品的裂缝形态、导流能力等参数时，其岩石样品四周存在金属框架遮挡以及气液管路等，会产生干扰，导致核磁扫描无法充分旋转，因此无法采集岩石样品中水力裂缝或酸蚀裂缝的形态，同时无法实时掌握形成的水力裂缝或酸蚀裂缝的导流能力参数情况。现有相关技术中的装置无法较好地模拟真实的地层环境，测试结果可靠性较差，无法实现岩心内的流体分布、酸蚀裂缝或水力裂缝形态和导流能力的一体化监测。
其次，相关技术中的装置，为模拟真实地层的岩心受压情况，大多采用钢制或铁制等刚性物体挤压岩心的六面，该方法会导致刚性物体与岩心的接触间隙出现应力集中，影响岩石的整体力学性质，导致模拟情况不真实，无法获取可靠的测试结果。
另外，CN106896043B公开了一种真三轴应力下模拟起裂及评价裂缝渗流的装置，包括岩心夹持系统、真三轴应力加载系统、酸液及压裂液注入系统、渗流能力测量系统。其装置通过X轴、Y轴、Z轴三个平面加压，并使用带孔哈氏合金通透板压紧四氟橡胶密封套密封。但是，该四氟橡胶密封套左侧全开口，岩心压裂后易从左侧溢出，不能反映岩心真实的导流能力。
基于上述的技术问题，本申请实施例提供了一种真三轴酸压物模、导流能力一体同步测试装置及方法，装置包括：夹持模组，包括夹持器、X轴组件、Y轴组件、Z轴组件和全氟醚橡胶胶套，X轴组件、Y轴组件和Z轴组件均连接于夹持器，全氟醚橡胶胶套用于包裹岩心，所述X轴组件位于所述全氟醚橡胶胶套沿第一方向的相对两侧，所述Y轴组件位于所述全氟醚橡胶胶套的沿第二方向的相对两侧，所述Z轴组件位于所述全氟醚橡胶胶套沿第三方向的相对两侧，所述第一方向、所述第二方向与所述第三方向两两垂直；所述X轴组件、所述Y轴组件与所述Z轴组件至少一面与所述全氟醚橡胶胶套内侧紧密接触，所述X轴组件、所述Y轴组件、所述Z轴组件均有独立的液体腔室；伺服模组，与X轴组件、Y轴组件和Z轴组件连接，所述伺服模组用于使X轴组件、Y轴组件和Z轴组件的所述液体腔室发生变化；渗流模组，包括模拟井筒，模拟井筒的一端用于导入酸化压裂流体，其中一端位于岩心内；监测模组，监测模组用于监测酸化压裂流体的流量、岩心内的酸化压裂流体分布、酸蚀裂缝或水力裂缝形态和导流能力；夹持模组被配置为在伺服模组的带动下，使X轴组件、Y轴组件和Z轴组件的所述液体腔室发生变化，以挤压被全氟醚橡胶胶套包裹的岩心。
本申请实施例提供的一种真三轴酸压物模、导流能力一体同步测试装置及方法，通过设置上述的夹持模组，夹持模组可以实现四面刚性挤压以及两面通过液体腔室接触，相较于在岩心六面外侧均采用刚性接触以挤压岩心的传统方式，具有较均匀的应力分布，可以降低六面刚性接触造成的应力集中问题；另外，通过设置渗流模组，可以较好地模拟岩心内部的渗流情况，提高测试的准确性。其次，通过设置监测模组，可以实现岩心内的流体分布、酸蚀裂缝或水力裂缝形态和导流能力的一体化监测，一方面实验结果接近真实情况，另一方面可以降低成本，无需分步完成实验和测试。
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请的优选实施例中的附图，对本申请实施例中的技术方案进行更加详细的描述。在附图中，自始至终相同或类似的标号表示相同或类似的结构件或具有相同或类似功能的结构件。所描述的实施例是本申请一部分结构实施例，而不是全结构的实施例。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。下面结合附图对本申请的实施例进行详细说明。
参照图1所示，第一方面，本申请实施例提供了一种真三轴酸压物模、导流能力一体同步测试装置10，包括夹持模组100、伺服模组200、渗流模组300和监测模组400。
参照图2所示，具体地，夹持模组100包括夹持器110、X轴组件180、Y轴组件120、Z轴组件130和全氟醚橡胶胶套140。夹持器110可以提供稳定的支撑结构，确保各个组件的正确位置和运动轨迹。全氟醚橡胶胶套140用于包裹岩心A。
可以理解的是，全氟醚橡胶(Perfluoroether Rubber，简称为FFKM)具有出色的耐高温性能，可以在高温环境下保持稳定的性能，不易变形或老化，适合在高温条件下使用；另外，全氟醚橡胶具有优异的耐化学腐蚀性能，能够抵抗多种化学物质的侵蚀，不易受到腐蚀和损坏，保持较长的使用寿命；其次，全氟醚橡胶具有良好的密封性能，能够有效地防止液体或气体的泄漏，保证系统的密封性和稳定性；全氟醚橡胶具有较高的耐磨性能，能够抵抗摩擦和磨损，保持表面光滑，延长使用寿命。全氟醚橡胶是一种环保材料，不含氟利昂等有害物质，符合环保要求，对人体和环境无害。
通过使用全氟醚橡胶胶套140包裹岩心A，全氟醚橡胶胶套140保护和固定岩心A，防止岩心A在夹持过程中受损或移动。另外，全氟醚橡胶胶套140可以保证岩心A与外部环境的密封，不会影响酸化压裂流体对岩心A的影响，进而保证测试与实验的可靠性。需要说明的是，岩心A仅四个侧面被全氟醚橡胶胶套140包裹，如X轴与Y轴两个方向上的四个侧面。
X轴组件180、Y轴组件120和Z轴组件130均连接于夹持器110，X轴组件180位于全氟醚橡胶胶套140沿第一方向的相对两侧，Y轴组件120位于全氟醚橡胶胶套140的沿第二方向Y的相对两侧，Z轴组件130位于全氟醚橡胶胶套140沿第三方向Z的相对两侧，第一方向、第二方向Y与第三方向Z两两垂直。这样，装置10可以实现多轴运动控制，精确定位和夹持目标物体。
可以理解的是，第一方向即为X轴方向，第二方向Y即为Y轴方向，第三方向Z即为Z轴方向。
这样，X轴组件180、Y轴组件120和Z轴组件130分别位于全氟醚橡胶胶套140的不同侧，使得岩心A可以在三个方向上被夹持和固定，以实现多轴夹持和固定，提高夹持的稳定性和精度。
其中，X轴组件180、Y轴组件120和Z轴组件130中的至少一者与全氟醚橡胶胶套140内侧紧密接触，以挤压被全氟醚橡胶胶套140包裹的岩心。
所述X轴组件、所述Y轴组件、所述Z轴组件均有独立的液体腔室，液体腔室连通于全氟醚橡胶胶套140；通过设置液体腔室，可以在全氟醚橡胶胶套140周围形成一定的液体压力环境，有利于液体的均匀分布和传递，提高对岩心A的挤压效果。
伺服模组200与X轴组件180、Y轴组件120和Z轴组件130连接，伺服模组200用于使X轴组件180、Y轴组件120和Z轴组件130的液体腔室发生变化。
渗流模组300包括模拟井筒310，模拟井筒310的一端用于导入酸化压裂流体，其中一端位于岩心A内；模拟井筒310可以在实验室环境中模拟井下条件，可以模拟实际油田中的地下岩石结构和流体渗透情况，使得对酸化压裂流体在岩心A中的渗流行为进行研究和测试成为可能。
监测模组400用于监测酸化压裂流体的流量，且用于监测岩心A内的流体分布以及酸化压裂流体作用后岩心的导流能力。监测模组400可以实时监测酸化压裂流体的流量，了解在模拟井筒310中的流体行为，同时监测岩心A内的酸蚀裂缝或水力裂缝形态，为研究岩石渗流特性提供数据支持。
夹持模组100被配置为在伺服模组200的带动下，使X轴组件180、Y轴组件120和Z轴组件130的液体腔室发生变化。若液体腔室的压力发生变化，如压力增大，液体腔室会挤压被全氟醚橡胶胶套140包裹的岩心A。通过夹持模组100的移动，可以实现对岩心A的均匀挤压，确保全氟醚橡胶胶套140对岩心A的包裹和压实效果，提高实验的准确性和可靠性。
可以理解的是，在夹持模组100中，可以是X轴组件180、Y轴组件120和Z轴组件130中的一者直接接触并挤压全氟醚橡胶胶套140；也可以通过液体腔室带动其他结构挤压全氟醚橡胶胶套140，以实现间接挤压。
通过设置上述的夹持模组100，液体腔室相较于刚性挤压，具有较均匀的应力分布，可以降低应力集中带来的不良影响；另外，通过设置渗流模组300，可以较好地模拟岩心A内部的渗流情况，提高测试的准确性。其次，通过设置监测模组400，可以实现岩心内的流体分布、酸蚀裂缝或水力裂缝形态和导流能力的一体化监测，实现测试与监测的同步完成，一方面实验结果接近真实情况，另一方面可以降低成本，无需分步完成实验和测试。
作为一种可选的实施方式，X轴组件180、Y轴组件120和Z轴组件130中的一者包括框架181，框架181与全氟醚橡胶胶套140之间形成第一液体腔室182。通过框架181与全氟醚橡胶胶套140形成的第一液体腔室182，第一液体腔室182与伺服模组200连通，可以实现对液体的控制和传递，确保液体在挤压岩心A过程中的均匀分布和作用效果。
第一液体腔室182被配置为在框架181的带动下发生变化，以挤压被全氟醚橡胶胶套140包裹的岩心A。通过带动框架181，使第一液体腔室182发生变化，实现对被全氟醚橡胶胶套140包裹的岩心A的挤压操作，确保对岩心A的处理效果和操作精度。
可以理解的是，第一液体腔室182可以用于刚性结构无法抵接的位置，可以直接抵接全氟醚橡胶胶套140，即第一液体腔室182内的液体可以直接挤压岩心A，相较于在岩心六面外侧均采用刚性接触以挤压岩心的传统方式，可以降低六面刚性接触造成的应力集中问题。
X轴组件180、Y轴组件120和Z轴组件130中的另两者中的至少一者包括间接压头121和挡板122，间接压头121相对挡板122靠近全氟醚橡胶胶套140，间接压头121与挡板122间隔设置以形成第二液体腔室123；第二液体腔室123实现了对液体的控制和传递，确保液体在挤压岩心A过程中的均匀分布和作用效果。

可以理解的是，第二液体腔室123通过间接压头121间接抵接全氟醚橡胶胶套140，即第二液体腔室123内的液体可以间接挤压岩心A，用户可以通过调整第二液体腔室123内的液体压力来调节间接压头121对全氟醚橡胶胶套140的挤压力，具有较高的调节精度，有利于实现精准的实验和测试。
需要说明的是，第一液体腔室182、第二液体腔室123的形状可以是任意的。示例性的，第一液体腔室182与第二液体腔室123的形状相同，均为长方体或圆柱体等；另一示例性的，第一液体腔室182与第二液体腔室123的形状不同，如第一液体腔室182为长方体，第二液体腔室123为圆柱体。本申请实施例对第一液体腔室182、第二液体腔室123的具体形状并不加以限定，也不局限于上述示例。

加热件170与温感件160电连接，加热件170用于获取温感件160获取的温度信息，并加热全氟醚橡胶胶套140。这样，根据温感件160获取的温度数据，通过控制加热件170的工作状态和功率，实现对全氟醚橡胶胶套140的加热控制，确保实验操作的温度要求和稳定性。
可以理解的是，通过设置温感件160和加热件170，可以模拟地层的实际温度状态，以模拟真实的地层。

S400、开启渗流模组，将酸化压裂流体导入模拟井筒内；
启动渗流模组300，将预先准备好的酸化压裂流体导入模拟井筒310内，模拟地下岩石受到酸化压裂的作用。这样可以进行相关实验研究，了解岩石的性质和反应情况。
通过开启渗流模组300，可以将酸化压裂流体导入模拟井筒310内，模拟地下岩石受到酸化压裂的环境，进行相关实验研究。
S500、监测模组监测酸化压裂流体的流量、岩心内的酸化压裂流体分布、酸蚀裂缝或水力裂缝形态和导流能力。
