Description

一种钻井废弃物的回注系统及回注方法
本申请要求于 2014 年 04 月 16 日提交中国专利局、 申请号为 201410153268.9、 发明名称为 "一种钻井废弃物的回注系统及回注方法" 的中 国专利申请的优先权, 其全部内容通过引用结合在本申请中。
技术领域
本发明涉及陆地钻井废弃物的处理技术领域,特别涉及一种钻井废弃物的 回注系统及回注方法。 背景技术
众所周知,在钻井的过程中将会产生大量的废弃物, 这些废弃物大致分为 三种, 其中一种为纯固相废弃物, 一种为纯液相废弃物, 还有一种为固液混合 的废弃物, 这些废弃物中通常都包含有大量的有害化学物质, 若不及时进行处 理, 会对自然环境造成较为严重的污染。
钻井废弃物回注法是一种较为成熟的废弃物处理方法,所谓钻井废弃物回 注法就是将钻井废弃物与水进行混合后形成可泵送的浆液,然后将浆液回注到 深层的井底里。
目前钻井废弃物回注系统中包括固相废弃物回注系统、液相废弃物回注系 统, 固液混合废弃物的回注目前是借用固相废气物回注系统进行,相比于固相 废弃物的处理, 固液混合废弃物的回注过程中所需要加入的水分较少。
固相废弃物回注系统一般包括废弃物研磨设备、 制胶设备以及回注泵等, 其中废弃物研磨设备需要与喷水设备配合工作,两者共同协调工作将固相废弃 物研磨成为可以泵送的浆体,制胶设备主要是将浆体制备成适合回注的胶性浆 体, 回注泵最后将适合回注的胶性浆体回注到深层井底; 液相废弃物回注系统 一般包括油水分离装置和回注泵,其中油水分离装置用于将液相废弃物中的油 和水进行分离, 并将油进行储存, 而剩余的水通过回注泵回注到井底深层。

本发明核心是提供一种钻井废弃物的回注系统,该钻井废物的回注系统可 以显著降低整个系统的占地面积, 并且还可以有效合理的利用水资源,避免水 资源的浪费。
为了使本技术领域的人员更好地理解本发明方案,下面结合附图和实施方 式对本发明作进一步的详细说明。
首先请参考图 1 , 图 1为本发明一种实施例中所提供的钻井废弃物的回注 系统的示意图。
本发明实施例中所提供的钻井废弃物的回注系统中,包括固相废弃物回注 子系统、液相废弃物回注子系统以及供水管路, 其中固相废弃物回注子系统中 包括研磨设备组、与研磨设备组串接的制胶设备以及与制胶设备串联的回注泵 13 ,供水管路主要用于为研磨设备组研磨固相废弃物供水, 液相废弃物回注子 系统中包括油水分离装置, 并且油水分离装置的出水口和供水管路相连。
本领域技术人员可以理解的是, 所谓相连具体是通过管道连接, 并且通常 情况下, 用于连接两个设备或者部件之间的管道上应设置有开关阀。
由上述实施例中可以看出,本发明中所提供的钻井废弃物的回注系统可以 同时对固相废弃物和液相废弃物进行处理,实现了固相和液相废弃物的一站式 处理, 并且两套子系统设置在一起还可以有效减小占地面积, 降低整套钻井废 弃物回注系统对工作场地的要求,固相废弃物回注子系统和液相废弃物回注子 系统之间协同工作, 形成一个固相和液相废弃物同时处理的大系统, 并且液相 废弃物回注子系统中所产生的水直接供给固相废弃物回注子系统中的研磨设 备组制浆使用, 这可以有效利用液相废弃物回注子系统中所产生的水,从而减 少固相废弃物回注子系统在制浆过程中对其他方式供水的消耗量,减少水资源 的浪费。
本发明实施例中的研磨设备组中包括一级研磨罐 5和二级研磨罐 6 , 请参 考图 1 , 其中一级研磨罐 5对固相废弃物进行初级粗磨, 一级研磨罐 5通过其 内部的搅拌器对固相废弃物进行搅拌研磨 ,经过初级粗磨后的固相废弃物将被 泵送到与其串联的二级研磨罐 6内进行细磨,二级研磨罐 6通过其内部的搅拌 器对固相废弃物进行搅拌研磨, 为了进一步使固相废弃物细化, 本发明实施例 中所公开的研磨设备组中, 至少包括两个串联的二级研磨罐 6, 经过第一个二 级研磨罐 6研磨后的固相废弃物将再次被泵入第二个二级研磨罐 6内进行再次 细化研磨。在实际固相废弃物处理的过程中, 可以根据需要设置更多的二级研 磨罐 6。
需要进行说明的是,图 1和图 2中的箭头方向分别代表物料在系统中的流 动方向, 在大多数的情况下, 由于场地或者设备的限制, 固相废弃物产生之后 并不能直接被送至研磨设备组中进行研磨,通常需要釆用车辆将其运输至研磨 设备组中进行研磨, 这不仅会增加车辆的运输成本, 而且在车辆在倾倒固相废 弃物时还容易与研磨设备组之间发生碰撞或者干涉, 导致研磨设备组出现故 障, 为此本实施例中还设置了用于为研磨设备组输送固相废弃物的送料装置。
请参考图 1 , 本实施例中提供了一种较为优选的送料装置的组成形式, 该 送料装置包括 选箱 3、第一螺旋输送器 1、第二螺栓输送器 4以及废物箱 28 , 其中第一螺旋输送器 1用于将车辆运输来的固相废弃物输送到筛选箱 3 的顶 部, 过滤装置 2设置在筛选箱 3的顶部, 且与筛选箱 3的内腔相通, 过滤装置 2 用于将粒度适合直接进行粗磨和粒度不适合直接进行粗磨的固相废弃物筛 分开来, 并且适合进行粗磨的固相废弃物将会通过过滤装置 2进入到筛选箱 3 内部, 第二螺旋输送器 4与 选箱 3的底部相连, 并且用于将 选箱 3底部的 固相废弃物输送至研磨设备组中,如图 1中所示。被过滤装置 2所筛分出来的 较大的颗粒则直接进入到与过滤装置 2相连的废物箱 28内等待其他方式的处 理。
更进一步的, 如图 1 中所示, 还可以在过滤装置 2的上方设置喷水管路 15 , 以避免过滤装置 2发生堵塞, 可以理解的是, 喷水管路 15可以直接与自 来水管路连接来进行供水,但是该种供水方式显然会浪费大量的自来水, 本实 施例中所提供的钻井废弃物回注系统中, 喷水管路 15优选的与油水分离装置 的出水口相连,这就使得液相废弃物回注子系统中所产生的水同时可供给喷水 管路 15进行使用, 从而进一步节省了水资源。
固相废弃物经过研磨设备组的研磨后大部分可以达到制胶的粒度要求,但 是仍然不可避免的存在着较少部分的大颗粒,若完成研磨的固相废弃物若直接 进入到制胶设备中, 容易导致制出的胶性浆体不符合回注要求, 为此本实施例 中对上述技术方案进行了优化,如图 1中所示, 本实施例中所提供的钻井废弃 物的回注系统中,固相废弃物回注子系统中还包括设置于研磨设备组和制胶设 备之间的振动筛 7 , 振动筛 7用于将所含微粒合格的浆料和所含微粒不合格的 浆料进行筛分, 并且振动筛 7上设置有回流管 8和输送管 9, 其中回流管 8可 供所含微粒不合格的浆料重新回流至研磨设备中进行研磨,输送管 9用于将合 格浆料输入到制胶设备中进行制胶。
制胶过程中若是浆液的粘性达不到回注要求,那么需要向研磨好的浆液中 加入制胶化学药品,通常情况下, 需要将化学药品直接加入到研磨好的浆液中 进行制胶,但是该种制胶方式中存在较大的弊端, 制好的胶性浆体容易在制胶 设备中发生凝结, 导致制胶设备的堵塞, 这对于胶性浆体的输送极为不利。
为此本实施例中对制胶设备进行了改进,如图 1中所示, 该制胶设备包括 浆料腔 10和胶液腔 11 , 其中浆料腔 10用于接收研磨好的固相废弃物浆体, 并通过其上设置的搅拌器持续不断地进行搅拌, 胶液腔 11 中用于储存配置好 的胶液, 其中浆料腔 10的底部设置有浆料管, 浆料管用于输送浆料腔 10中的 浆料, 胶液腔 11的底部连通有胶液输出管和胶液回流管 12, 并且浆料管与胶 液输出管并联在同一管路上, 因此当胶液输出管和浆料管上的阀体打开后,研 磨好的浆料将与胶液进行混合形成适合回注的胶性浆体, 胶液回流管 12的端 部分别与浆料腔 10和胶液腔 11相连通, 并且胶液回流管 12上设置有用于盛 装制胶用化学药品的漏斗状容器, 在胶液回流管 12中的胶液回流时, 化学药 品将进入胶液回流管 12中并与其中的胶液混合, 胶液回流管 12与浆料腔 10 连通主要是为了利用胶液的粘性来清理浆料腔 10底部的泥沙等沉淀物, 如图 1 中所示, 胶液配置过程中所需的水来自于与胶液腔 11相通的水管。 由此可 见, 本实施例中所提供的制胶设备不仅可以有效解决之前的堵塞问题, 而且还 可以有效清理浆料腔 10中残存的泥沙等杂质。
被制成胶性浆体的固相废弃物即可直接通过回注泵 13 注入到深层井底 内, 当然, 若是胶性浆体较多, 还可以设置带有搅拌器的暂存箱 14, 如图 1 中所示, 不能及时回注的胶性浆体可以暂存在暂存箱 14内等待回注。
更进一步的, 本发明实施例中所提供的钻井废弃物的回注系统中,还包括 用于处理固相和液相混合废弃物的混合相废弃物回注子系统, 请参考图 1 , 该 混合相废弃物回注子系统中包括过滤器 20、 与过滤器 20相连的输送总管 21 , 并且输送总管 21 上设置有分别与振动筛 7和研磨设备组相通的第一支管 22 和第二支管 23 , 其中过滤器 20主要用于过滤混合相废弃物中的大块固相废弃 物, 若经过过滤器 20后的混合相废弃物中的固相废弃物粒度较小, 则可直接 打开第一支管 22上的开关阀,通过第一支管 22泵送到振动筛 7位置进行筛分; 若经过过滤器 20后的混合相废弃物中的固相废弃物粒度较大, 则可打开第二 支管 23上的开关阀, 通过第二支管 23被首先泵送到研磨设备组中进行研磨, 然后通过固相废弃物回注子系统被最终回注到深层井底。
本发明实施例中所提供的液相废弃物回注子系统中的油水分离装置如图 1中所示, 包括沉降罐 16、 油水分离罐 17、 储油罐 18和储水罐 19, 其中沉降 罐 16主要用于液相废弃物短暂的沉降, 沉降后的液相废弃物将被泵入油水分 离罐 17中进行油水分离, 由于油分的密度小于水, 因而油水分离罐 17的上半 部分将为油分, 下半部分为水分, 储油罐 18与油水分离罐 17的上部相连, 储 水罐 19与油水分离罐 17的下部分相连, 并且储水罐 19的出口与供水管路相 连, 图 1中的储水罐 19具体设置有两个, 本领域技术人员可以根据实际情况 的需要适当进行数量上的加减。
由于混合相废弃物的处理需要与固相废弃物的处理共用全部或者部分通 道, 因而为了暂存无法被及时处理的混合相废弃物, 本发明实施例中还增设了 緩存箱 25 , 如图 1中所示, 该緩存箱 25上设置有可向研磨设备组泵送浆料的 管路, 并且混合相废弃物回注子系统的输送总管 21上还设置有带有开关阀并 且与緩存箱 25相连的第三支管 24 , 若混合相废弃物无法被及时处理, 则可暂 存在緩存箱 25内等待被送入研磨设备组中进行研磨。 更进一步的, 本实施例 中储水罐 19的出水口还通过带有开关阀的旁通管与緩存箱 25连通,因而液相 废弃物回注子系统中暂时没有被利用的水也可存入緩存箱 25内部。
由以上实施例的介绍可以看出, 本发明中所提供的钻井废弃物回注系统 中, 可以一站式实现固相废弃物、 液相废弃物以及混合相废弃物的处理, 这可 以有效提高钻井废弃物的处理效率, 降低整个系统对场地的要求, 同时本发明 中所提供的钻井废弃物回注系统还实现了对水资源的循环利用,降低了废弃物 回注过程中水资源的浪费。
为了使工作人员实时监控整个系统的运行,还可以增设控制系统,控制系 统中应当包括对各个设备运行状态进行釆集的数据釆集器,并且可以根据控制 器内所存储的参数对设备的运行状态进行适当调节,以便实现整个系统在最佳 状态下的自动运行。
请参考图 2 ,图 2为本发明另一实施例中所提供的钻井废弃物的回注系统, 该种实施例与图 1中所对应的实施例的区别仅为:筛选箱 3中的固相废弃物到 研磨设备组的输送方式不同,图 1中所公开的输送方式为通过第二螺旋输送器 4将筛选箱 3中的固相废弃物输送到研磨设备组, 而本实施例中所公开的输送 方式为釆用挖掘机 27将将 选箱 3中的固相废弃物输送到研磨设备组中。
当然,本领域技术人员还可以根据实际情况需要釆用多种送料装置完成从 筛选箱 3到研磨设备组的固相废弃物的输送, 例如釆用离心泵、 输送带等等, 本发明中对此不再进行——列举。
本发明中还提供了一种钻井废弃物的回注方法,该回注方法中包括固相废 弃物处理和液相废弃物处理, 并且固相废弃物处理中包括研磨工序、制胶工序 以及回注工序; 液相废弃物处理中包括油水分离工序、并且液相废弃物处理中 的油水分离工序中所产生的水供给固相废弃物处理中的研磨工序。
以上实施例中所提供的技术方案,将固相废弃物和液相废弃物处理进行了 整合, 实现了固相和液相废弃物的一站式处理, 并且液相废弃物处理中所产生 的水直接供给固相废弃物处理中的研磨工序,这可以有效利用液相废弃物处理 过程中所产生的水,从而减少固相废弃物处理在制浆过程中对其他方式供水的 消耗量, 减少水资源的浪费。 为了进一步优化上述实施例中的技术方案,本实施例中所提供的钻井废弃 物的回注方法中,固相废弃物处理时,在研磨工序之前还增加了喷水分拣工序, 通常情况下该工序是通过过滤装置进行分拣的, 具体的, 在喷水的同时釆用过 滤装置对固相废弃物进行分拣过滤,并且可以通过过滤装置的固相废弃物进入 到研磨工序中进行研磨, 更为优选的, 该工序中所需的水为液相废弃物处理中 的油水分离工序所产生的水,这可以进一步降低固相废弃物处理过程中对水资 源的浪费, 提高液相废弃物处理中所产生的水的利用率。
本领域技术人员容易理解的是,还可以将液相废弃物处理中所产生的水通 往固相废弃物处理中的制胶工序中, 或者其他用水的工序中, 以便于进一步提 高液相废弃物处理中所产生的水的利用率。
为了确保经过研磨后的固相废弃物能够成为符合回注要求的浆料,在进行 固相废弃物处理时, 本实施例中优选的在研磨工序之后还增加了筛分工序, 筛 分是通过振动筛实现的, 具体的,将研磨工序中所研磨好的浆料通过振动筛进 行筛分, 并且将可通过振动筛的浆料送入到制胶工序中, 将被振动筛阻隔的浆 料送回至研磨工序中继续进行研磨, 以确保研磨完成后的浆料符合回注要求。
为了进一步完善上述实施例中所提供的钻井废弃物的回注方法,本实施例 中所提供的回注方法中还包括:
混合相废弃物处理, 该工序包括过滤工序, 并且将可通过过滤器的混合相 废弃物送至所述筛分工序中,将被所述过滤器阻隔的固相废弃物送至所述研磨 工序中, 由此可见, 混合相废弃物处理与固相废弃物处理也进行了整合, 并与 固相废弃物处理共用研磨工序、 筛分工序、 制胶工序以及回注工序等, 这就在 最大限度的节省投入的情况下, 实现了同时对多种废弃物进行处理。
以上对本发明所提供的钻进废弃物的回注系统及回注方法进行了详细介 例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出,对于本技 术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以对本发明 进行若干改进和修饰, 这些改进和修饰也落入本发明权利要求的保护范围内。
