具体实施方式
下面将结合附图对本公开的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在本公开的描述中，需要说明的是，如出现术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等，其指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开的限制。此外，如出现术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。
另外，在本公开实施例的描述中，除非另有明确的规定和限定，术语“相连”、“连接” 应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本公开中的具体含义。
第一实施例：
如图1和图2所示，本公开实施例提供的非金属敷缆连续油管，包括：内衬管100，所述内衬管100用于形成介质输送的通道，用于运输原油。由内向外，内衬管100的外壁上依次设置有线缆内嵌层200和保护套300，线缆内嵌层200包括线缆和多条增强带210，所述增强带210用于抵抗扭转变形且承受轴向拉力；所述保护套300用于防止所述线缆磨损。本公开实施例提供的非金属敷缆连续油管中嵌入有线缆，而非传统方式中，将线缆外置，解决了传统钢制油管需要外置独立线缆进行单独铠装，作业费时费力且成本高，线缆容易损坏的弊端，从很大程度上降低了线缆的磨损速率，延长了线缆的使用寿命，提高了采油效率，降低了采油成本。
因为非金属敷缆连续油管的工作环境特殊，保护套需要具有耐磨耐腐蚀性能。本实施例中，保护套300的材料可以为高分子材料，高分子材料具有优良的耐磨耐腐蚀性能。其它实施例中，保护套可以为其它耐磨耐腐蚀的材料。
根据需要线缆的种类和数量，线缆内嵌层200的数量可以为多个。例如，每一层线缆内嵌层200中嵌入的线缆的种类可以相同，根据种类的不同，由内向外设置多层线缆内嵌层200，逐层加工，互不影响。
具体的，增强带210的材质包括纤维和树脂。具体的，在实际加工过程中，增强带210由纤维和树脂按一定比例混合浸润后缠绕到内衬管100外侧的层位上再固化成型其中层位指的是内衬管100外的螺旋槽，用来形成增强带210的固化形态，当增强带210固化后，螺旋槽就与U型耐磨带相互配合，U型耐磨带用于将相邻的增强带210隔离，方便增强带210的成型。增强带210的宽度范围在8～15mm。本实施例中，增强带的宽度为12mm，其它实施例中，增强带的宽度也可以为10mm、14mm等。
还需要说明的是，多层线缆内嵌层200的层与层之间以及增强带210之间均为非粘结的可以相对滑移的，层与层、带与带之间可以相对滑移，螺旋槽和U型耐磨带的配合避免了内衬管100在滑移时对增强带210造成磨损。
每个线缆内嵌层200中，多个所述增强带210围绕所述内衬管100轴向螺旋缠绕排列，这种螺旋缠绕的方式大大提高了非金属敷缆连续油管的抗拉强度。
如图3所示，线缆可以根据需要设置于多个增强带之间或者单个增强带中。在一个实施方案中，至少有两个相邻的所述增强带210之间存在让位间隙，所述让位间隙用于容纳 线缆，以使所述线缆围绕所述内衬管100轴向螺旋缠绕。线缆缠绕采用取代原纤维增强带210的位置的方式将线缆缠绕至内衬管100上，线缆得到了很好的固定。在另一个实施方案中，线缆也可以直接内嵌于所述增强带210内。
本公开实施例提供的非金属敷缆连续油管可以包括上述两种实施方式，根据需要固定的线缆的粗细程度可以采用不同的固定方式。具体的，当线缆较粗时，可以采用让位的方式固定线缆，也就是两条增强带210夹持固定一条线缆；而当线缆较细时，可以在加工时直接将线缆加工入增强带210中。这样线缆的保护效果更佳。
具体的，本公开实施例提供的线缆内嵌层200的数量可以为两个且分别为内层和外层，所述内层设置在所述内衬管100的外侧，所述外层设置在所述内层的外侧。内层的线缆为信号缆220，因为信号缆220较细，在所述内层中，所述信号缆220内嵌于所述增强带210内。所述外层的线缆为动力缆230，因为动力缆230较粗，在所述外层中，至少有两个相邻的所述增强带210之间存在让位间隙，所述让位间隙用于容纳所述动力缆230，以使所述动力缆230围绕所述内衬管100轴向螺旋缠绕。
由于动力缆230和信号缆220的位置不同，因此动力缆230和信号缆220采用不同的缠绕工艺，对于动力缆230缠绕采用取代原增强带210的位置的方式将动力缆230缠绕至内衬管100上，动力缆230得到了很好的固定。对于信号缆220缠绕采用信号缆220包覆于纤维中和增强带210一起缠绕至管体上，信号缆220受到增强带210的固定和保护，避免了磨损。
详细地，动力缆230的水平横截面呈椭圆形，信号缆220的水平横截面呈圆形，由于线缆缆芯外有烧结层和护套层，因此椭圆形和圆形能够保证外层均匀烧结至烧结层，保证烧结质量，提高线缆使用性能。
内衬管100可以根据需要采用非金属管或金属管，本实施例中，内衬管100采用给金属管，非金属敷缆连续油管中除了可以铺设动力缆230和信号缆220外，还可铺设其他线缆或光纤等，应用范围广范。其它实施例中，内衬管100也可以为金属管。
内层中的增强带210与所述外层中的增强带210的螺旋方向相反。螺旋方向相反可以抵抗扭转变形。
动力缆230与所述信号缆220在径向上错位设置，用于降低所述动力缆230与所述信号缆220彼此之间的干扰。动力缆230和信号缆220分别内置在内外两个线缆内嵌层200内，成螺旋交叉分布，避免两种线缆内嵌于同一层平行排列，动力缆230对信号缆220造成干扰。
需要说明的是，其它实施例中，线缆内嵌层200的数量可以为三个或者四个，任意相邻两个线缆内嵌层200的增强带的螺旋方向相反；动力缆230和信号缆220的水平横截面 也可以呈其它形状，比如均为圆形或者方形。
本公开实施例提供的一种非金属敷缆连续油管，包括内衬管100、保护套300和线缆内嵌层200，线缆内嵌层200包括增强带210、动力缆230、信号缆220，其中所述线缆内嵌层200分为左旋和右旋两层，线缆内嵌层200中嵌有动力缆230、信号缆220，动力缆230用于为油井设备电器输送电力，信号缆220为井下仪器信号传输提供通道，动力缆230和信号缆220分别内置在左右两个线缆内嵌层200内，成螺旋交叉分布。保护套300为高分子材料。
具体地，动力缆230位于线缆内嵌层200(左旋)上，且宽度同纤维增强带210的宽度相同，均布缠绕在线缆内嵌层200上，信号缆220位于线缆内嵌层200(右旋)上，且位于线缆内嵌层200中的增强带210的中间位置。
本公开实施例提供的非金属敷缆连续油管，将各种线缆以不同的形式分别内嵌于线缆内嵌层200中，既保护线缆不受磨损，使线缆具有与内衬管100同等的使用寿命，同时又提高了内衬管100的抗拉强度。
可选地，内衬管100和线缆内嵌层200之间设置有环向增强层400；环向增强层400包括第一纤维集束和第二纤维集束，所述第一纤维集束和第二纤维集束以不同的螺旋方向交叉缠绕固定在所述内衬管100上。具体的，加工时，由纤维集束浸胶后，在张力控制下直接缠绕到层位上，第一纤维集束和第二纤维集束分别沿左旋方向和右旋方向交叉螺旋缠绕最后固化成型。交叉缠绕的结构形式可以有效提高环形增强层的里写性能，从而提高整个连续油管的抗弯扭性能。
环向增强层400和线缆内嵌层200之间设置有骨架层500，以进一步地提高整个连续油管的抗弯扭性能。所述骨架层500包括多条缠绕在所述环向增强层400上的纤维带。具体加工时，可以由两组纤维带浸胶后大角度同时缠绕到内衬管100的层位上。同时，纤维带之间可以设置L型的PVC隔断薄膜，以保证纤维带固化后相互不粘接在一起，同时起到了防止多条纤维带之间磨损的作用。
内衬管100与所述环向增强层400之间、所述环向增强层400与所述骨架层500之间、所述骨架层500与所述线缆内嵌层200之间、所述线缆内嵌层200与所述保护套300之间均为滑动套接。也就是非金属敷缆连续油管中层与层之间是互不粘连，能够相互滑动的，可以通过外包耐磨带的方式实现。通过非金属敷缆连续油管的层与层之间可以相对滑移，来实现管材的弯曲，而非通过材料的弹性变形来实现弯曲，提高管材的强度，拉伸伸长率低。
增强带210、环向增强层400和骨架层500中的纤维采用湿法缠绕的方式成型。湿法缠绕具有以下优点：a、成本较干法缠绕大幅降低；b、产品气密性好，因为缠绕张力使多余 的树脂胶液将气泡挤出，并填满空隙；c、纤维排列平行度好；d、湿法缠绕时，纤维上的树脂胶液可减少纤维的磨损；e、生产效率高；f、可实现长距离连续管的生产；g、可根据产品需求随时更改树脂及纤维的含量。
第二实施例：
请参照图1-2，本公开实施例提供了一种非金属敷缆连续油管，其包括从内到外依次连接的内衬管100、线缆内嵌层200及保护套300；
其中，线缆内嵌层包括线缆和多条增强带210，多条增强带210螺旋缠绕于内衬管100的外壁，所述线缆设置于所述增强带210中或者多条所述增强带210之间。
本公开通过在非金属敷缆连续油管中嵌入有线缆，而非传统方式中，将线缆外置，解决了传统钢制油管需要外置独立线缆进行单独铠装，作业费时费力且成本高，线缆容易损坏的弊端，从很大程度上降低了线缆的磨损速率，延长了线缆的使用寿命，提高了采油效率，降低了采油成本。
第三实施例：
请参照图1，本公开实施例提供了一种非金属敷缆连续油管，其包括从内到外依次活动连接的内衬管100、环形增强层400、骨架层500、线缆内嵌层200及保护套300。内衬管100、环形增强层400、骨架层500、线缆内嵌层200及保护套300的横截面均大致为圆环状，上述“横截面”指的是垂直于连续油管的轴线方向的平面。
其中，线缆内嵌层200设置有两个且分别为内层和外层，内衬管100、环形增强层400、骨架层500、内层、外层及保护套500从内到外依次活动连接。详细地，内层包括两条信号缆220和多个增强带210，多个增强带210绕内衬管100的轴线螺旋缠绕于内衬管100的外壁，两条信号线220分别内嵌于两个增强带210内部，以作为井下仪器信号传输提供通道。
外层包括两条动力缆230和多个增强带210，多个增强带210绕内衬管100的轴线螺旋缠绕于内衬管100的外壁，且外层的增强带210的螺旋方向与内层的增强带210的螺旋方向相反。多个增强带210之间设置有两个让位间隙，其中一个让位间隙由其中两个相邻的增强带210形成，另外一个让位间隙由另外两个相邻的增强带210形成，两条动力缆230分别设置于两个让位间隙中，用于为油井设备电器输送电力。通过将不同作用的信号缆220和动力缆230分别设置于不同的线缆内嵌层200，可以在方便加工的同时，更好地对线缆进行保护。
内衬管100、环形增强层400、骨架层500、线缆内嵌层200及保护套300中任意两个结构之间活动连接，即互不粘连，可以相对移动，这样就可以在保证提高油管强度，降低拉伸率的同时，实现油管的弯曲，有效弥补现有油管弯曲只能通过弹性变形的方式。
最后应说明的是：以上所述实施例，仅为本公开的具体实施方式，用以说明本公开的技术方案，而非对其限制，本公开的保护范围并不局限于此，尽管参照前述实施例对本公开进行了详细的说明，本领域的普通技术人员应当理解：任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，其依然可以对前述实施例所记载的技术方案进行修改或可轻易想到变化，或者对其中部分技术特征进行等同替换；而这些修改、变化或者替换，并不使相应技术方案的本质脱离本公开实施例技术方案的精神和范围，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应所述以权利要求的保护范围为准。
