Description

本公开涉及但不限于石油钻井领域，尤其涉及一种应用于随钻核磁仪器的振动检测装置。
背景技术
目前，为了检测仪器性能，现有的随钻核磁仪器都需要在振动台上进行振动测试。但是，在目前测试过程中，随钻核磁仪器无法在振动台上同时进行回波信号测量，只能进行简单的振动测试，仅仅在结束振动后再通过外接LCR检测装置判断探头是好是坏。
由上述可知，上述检测过程，仪器无法在振动情况下进行高压发射测量，无法有效检测随钻核磁仪器性能，而且测试过程耗时长，操作也复杂。

详述
下文中将结合附图对本公开的实施例进行详细说明。需要说明的是，在不冲突的情况下，本公开中的实施例及实施例中的特征可以相互任意组合。
针对相关振动检测装置的缺陷，本公开实施例提供了一种应用于随钻核磁仪器的振动检测装置，其添加了悬空在振动台上侧的刻度桶，可在振动台上同时获取回波信号，确保仪器振动测量更全面，更好地检测仪器实际抗振动性能。
下面结合实施例阐述本公开的应用于随钻核磁仪器的振动检测装置。
请参阅图1至图7，本公开实施例提供了一种应用于随钻核磁仪器的振动检测装置，其包括振动台100和刻度桶300，振动台100设置为水平夹持着钻核磁仪器200，刻度桶300装有检测液，其中，该刻度桶300的下端设置有容纳随钻核磁仪器200的凹槽302，且凹槽302内设有与随钻核磁仪器200上表面对应的弧面303，另外，刻度桶300设置为悬空在振动台100的上侧，并与随钻核磁仪器200间隔设置，使得刻度桶300在振动台作用振动时一直保持静止状态，而处于振动的随钻核磁仪器200可实时发射高压信号，进行高压发射测量。由此，随钻核磁仪器200可在振动的同时获取刻度桶300 的回波信号，更加准确测得其性能，也会节省测试时长。
如图3所示，随钻核磁仪器200的中部形成环形的探头区域201，即探头天线线圈存在区域，探头区域201具有一定的探测敏感范围(正如图2中虚线所示)。上述振动台100可带动其上的随钻核磁仪器200振动，而为了夹持该随钻核磁仪器200，又如图1至图3所示，其上端设置有间隔的夹具101，两夹具101通过螺栓可拆安装在振动台100上，且可根据随钻核磁仪器200的长度调整两夹具101之间的距离。由此，上述两夹具101分别夹持着随钻核磁仪器200的两端，使得其保持水平。
关于刻度桶300，如图2至图5所示，该刻度桶300呈半圆柱状，其上端为弧形，下端水平，其下端面设置有底板307和凹槽302，底板307设置为水平，凹槽302设置为向刻度桶300的内侧凹陷，该凹槽302内的弧面303使得凹槽302截面为半圆形，该凹槽302贯通刻度桶300，且其长度大于上述探头区域201的长度，使得刻度桶300形成半圆桶状。而且弧面303与探头区域201的上表面相对应，是指当刻度桶300置于随钻核磁仪器200上侧时，该随钻核磁仪器200的轴线与上述弧面303的轴线重合，保证弧面303与探头区域201间距保持一致。另外，该刻度桶300内形成截面呈半环形的半环形腔306，半环形腔306内的检测液为硫酸铜溶液。刻度桶300上端还设置有连通内外的注入口304和流出口305，注入口304设置为与流出口305相间隔，操作人员可通过上述注入口304和流出口305加入检测液，而在检测时，上述注入口304和流出口305需用堵头封堵。上述注入口304和流出口305可设置为分别连接检测液源头和泵，其中，泵可为抽吸检测液提供动力，泵抽出刻度桶300内原有的检测液，并在抽吸力的带动下将检测液源头的新鲜检测液抽入到刻度桶300中，实现循环更换刻度桶300内的检测液。为了定位刻度桶300与随钻核磁仪器200的相对位置，如图2所示，该刻度桶300的端面设有三个定位标记308，其可为刻度桶300与随钻核磁仪器200居中放置定位所用。另外，刻度桶300主要由玻璃钢材质构成，其外部包裹一层金属外壳，金属外壳的材质可为合金铜或者不锈钢等，能够进行电磁屏蔽，其中，玻璃钢材质可以有效避免对仪器的探头区域201天线线圈电感的产生影响，由于刻度桶300外皮包裹了一层无磁材料的金属外壳(合金铜或 者不锈钢等材质)，使得刻度桶300不会影响到随钻核磁仪器静磁场的变化，且金属外壳良好的导通性能可以有效屏蔽仪器测量时空间电磁干扰的影响。
为了使的上述刻度桶300悬空在振动台100上侧，该振动检测装置还包括固定刻度桶300的支架400。如图1、图3、图6和图7所示，该支架400的两端支撑在地面上，其与振动台100无连接，其设置为垂直于振动台100的长度方向设置，并横跨振动台100。该支架400包括支架主体401和支脚402，支架主体401设置为与支脚402相接，其支架主体401垂直于振动台100，而支脚402设置在支架主体401的两端并向下延伸。其中，支架主体401由空心的钢管拼接成水平的方框结构，该方框结构内设有容纳刻度桶300的安装腔404，而安装腔404的底部又设有间隔的两块支撑板406，该支撑板406水平设置，用以支撑上述刻度桶300的底板307，而两支撑板406之间的空隙则避让开了刻度桶300上的凹槽302。另外，该刻度桶300还通过固定卡500定位固定在支架400上，其中，该固定卡包括水平部502和呈半圆形的圆弧部501，圆弧部501与刻度桶300的上表面匹配且焊接固定；水平部502水平设置在上述圆弧部501的两侧，相对应地，上述安装腔406在各自支撑板406的一侧都设有突出的固定筋407，上述水平部502设置为搭在固定筋407的上端且与其通过螺钉固定。另外，支架主体401在安装腔404的两侧设有多个加强筋405，可提升强度，保证结构稳定性。为了方便支架400移动，设置在支架400下端的支脚402，其底部设置有多个滚轮402，使得操作人员可轻松推动支架400，方便刻度桶300移动至振动台100上侧。
当随钻核磁仪器200需要进行振动测试时，首先，需要将钻核磁仪器200固定在振动台100上，并将固定由刻度桶300的支架400通过滚轮推到随钻核磁仪器200及振动台100的上方，使得刻度桶300悬空置于随钻核磁仪器200上方，探头区域201完全藏于刻度桶300的凹槽302内，同时，如图2所示，虚线内为探头区域201的探测敏感范围，可知刻度桶300的弧面303都处于探测敏感范围内，以进行振动下的刻度流体信号检测。如图2所示，随钻核磁仪器200可以实时发射高压信号，并探测刻度桶300内部的刻度流体回波信号，实现在振动的同时，进行仪器发射获取刻度桶内回波信号检测的目的。另外，虽然本振动检测只能探测到钻核磁仪器200上半部半圆柱形 刻度桶300内区域的刻度流体信息，但这不会影响到钻核磁仪器200在振动测试情况下同时完成检测刻度流体信号的目的。
由此，随钻核磁仪器200可在振动检测装置上完成上述振动测试，可以全面检测随钻核磁仪器200在振动下的各种性能。
在本公开另一个示例性实施例中，如图8所示，地面上设置有两条平行的滑道600，且支架400下端的支脚402未设置滚轮，并插入到滑道600内，形成支架400与地面的滑动连接，同样可便于支架400移动。
以上所述实施方式仅表达了本公开的几种实施方式，其描述较为具体和详细，但所述的内容仅为便于理解本公开而采用的实施方式，并非用以限定本公开。任何本公开所属领域内的技术人员，在不脱离本公开所揭露的精神和范围的前提下，可以在实施的形式及细节上进行任何的修改与变化，但本公开的专利保护范围，仍须以所附的权利要求书所界定为准。
