Description

具有防止形成沉积物的内涂层的管道和施加所述涂层的方法
技术领域
本发明涉及石油和天然气工业，更具体地，涉及防止在管道内表面上形成沉积物(沥青质、树脂和石蜡、盐、水合沉积物等)，且能够用于涂布在任何烃原料生产方法(石油或天然气)中所用的管道的内表面，不用考虑油井的使用条件和所提取原料的品质。
背景技术
存在用于涂布管道内表面的已知方法，所述方法提供了例如通过使用因压力差而压在管道表面的薄膜带形成的一层或多层涂层(参见2000年4月27日公告的专利RU 2144803)。
这种方法的缺点在于应用于管道内表面的薄膜带涂布方法的复杂特性、涂层对管道表面的低粘附性和低的耐外部腐蚀介质的性能。
存在利用聚合物材料对管道内表面进行涂布的已知方法，所述方法包括：在管道内表面上涂布这种处于稠密流动状态的材料，随后使其固化(参见1998年9月10日公告的专利RU 2118742)。
这种方法的缺点在于，所述熔融聚合物在热机械模件中快速冷却，使得不可能提供均匀的涂层或在聚合物和管道表面之间的牢固结合，这是因为在聚合物主体中发生强烈的热收缩过程。热机械模件沿管道的移动改变了挤出机和模件之间连接元件的长度，以及聚合物沿该元件经过的状况，这降低了涂层品质和聚合物对金属的粘附性。
存在通过压铸法利用热塑性材料来涂布管道表面的已知方法，所述方法包括：将金属管放入模具内；填充达到稠密流动状态的热塑性材料；加热模具；及随后固化并将材料从所述模具中取出(参见2002年7月10日公告的专利RU 2184903)。
这种方法的缺点在于工艺复杂性和与模具制造、特别是用于大尺寸管的模具制造有关的高成本，以及所述方法对于直径小于200mm的管的不适用性。
在石油和天然气工业中一个未解决的问题是，在烃原料生产(石油和天然气)的石油和天然气井所使用的管道壁上的沉积物。该过程从在任何气候条件下开始生产时开始，并持续直至完全阻塞管道。沉积物导致泵设备的加速磨损、管道清洁所花费的成本和时间的增加、因流动面积减少而产生的在管道中的压降，这加大了烃原料的生产不足。
根据烃原料的品质，在不同区域管道清洁操作的时间各不相同，从一天至一年。例如，在buzulukskoe区域，每1～15天清除石蜡沉积物，这取决于井，在Tumen区域该周期为5～20天，在Surgut区域该周期为7～30天。
发明内容
为了解决上述问题，本发明人对在管道内表面上形成沉积物的原因进行详细分析，提出了一种涂布管道内表面的设备和方法，作为解决这种问题的全面解决方案。
存在三个引起在管道内表面上沉积物形成的主要因素：
1.管道内表面的粗糙度；
2.在石油移动期间在管道内表面上的静应力；
3.在管道壁上的温差。
所述因素导致阻止沉积物形成的涂层的设备和方法的需求。
1.涂层厚度为2～8mm，以在管道壁上降低热传导并避免急剧的温差，
2.高度的涂层表面清洁度-光滑表面，
3.防止静应力累积。
除了规定的要求之外，还包括设计用于防止形成沉积物的那些内容，涂层自身和涂布方法应具有下列性质：
1.耐腐蚀介质(酸、碱)性；
2.均匀性、对金属良好的粘附性和水密性，以防止管道内表面的腐蚀；
3.弹性，耐裂纹性，在高达-60℃的温度下裂纹与冲击载荷和管道弯曲有关；
4.耐磨性，磨损与在莫氏(Moss)刻度中硬度高达7点的悬浮粒子的流动有关；
5.在-60～+110℃温度范围内保持涂层性能。
所提出技术方案的目的是创造一种涂布管道内表面的设备和方法，从而防止形成沉积物并提供用于任何烃原料生产方法中的长寿命涂层，而不必考虑井使用状况、提取的原料的品质，并且与上述规定的要求一致。
研究调查和多次试验为选择满足所述规定要求的材料(聚氨酯体系)选择提供了基础，其特性示于表1中。

得到如下技术效果：聚氨酯对管道内表面的高度粘附性、具有规定厚度的涂层的光滑表面。
通过一种方法获得了所述技术效果，所述方法涉及：将聚氨酯泵送到环状空腔中，所述环状空腔由管道的内表面和利用心轴插入且具有高度精整的表面的冲孔器形成；保持所述聚氨酯至其完全固化，随后将所述冲孔器从所述管道中取出，从而使得聚氨酯能够完全粘附到管道金属壁上，并能够获得具有光亮精整表面和均匀厚度的涂层。根据聚氨酯收缩比，所述管道可以设有由穿孔的金属筛制成的管，所述管的外径等于所述管道的内径。此外，当加工一些聚氨酯而需要时，在所述聚氨酯泵送之前，利用任何已知方法将所述管道加热至所需温度。
设备组件和涂布方法包括下列操作：
1.将水垢、灰尘和水分从管道内表面上除去，然后对所述表面去除油污。
2.将最小外表面精整度为第9级的塞子插入经清洁和去除油污的管道中。塞子的外径在塞子和管道内壁之间提供了间隙，其等于涂层厚度(2～8mm)。
3.在将塞子插入管道之前，利用单独的润滑剂对其外表面进行润滑以有助于其随后的取出。
4.当聚氨酯的收缩因数超过2％时，则在将塞子插入管道之前，将网管插入到管道的内部空间内，所述网管例如由穿孔的金属制成，其外径等于管道的内径且厚度不超过1.5mm。所述网抵抗聚氨酯的收缩，这提供了具有较好均匀性且对管道壁具有高粘附性的涂层。
5.利用心轴(2)将塞子(1)居中，所述心轴安装在管道面(3)上，同时一个心轴具有用于填充聚氨酯的连接管(4)(图1)。
6.为了满足对某些种类聚氨酯进行加工的工艺要求，使用管状加热元件、炉子或任何其它已知方法将组装的设备加热至所需温度，通常不超过80℃。
7.为了防止在涂层中形成空隙，将所述组装的设备安装在与底部的连接管垂直的位置，然后借助于连接管填充聚氨酯物质，直至空间填满。
8.在聚氨酯完全固化之后，将塞子沿水平位置从管道中取出。
9.对管道面进行机械加工以除去任何毛刺。
与规定材料组合，这种涂布设备和方法的使用提供了均匀涂层，所述涂层具有相等的厚度、光滑的表面、高的耐腐蚀介质的性能、对管道内表面的高粘附性、高耐磨性、耐高温性，这防止了沉积物的形成和相关后果，增加了生产井定期修理和大修之间的时间，最终增加了管道的使用寿命。
