         产品特点:Product Features

         一、适用范围广 Wide range of application

        本产品靠自洁式栅型缝隙尺寸来控制防砂范围,缝隙是由过滤芯片形成,可根据油田储层粒度分布特性进行缝宽的设计,因此防砂范围广,适应性强。

        The product controls the sand-proof range by the size of the self-cleaning grid type slit. The slit is formed by the filter core, and the slit with can be designed according to the distribution characteristics of the reservoir granularity of the oil field, so with the wide sand-proof range it is widely adaptable. 

        二、防砂精度高 High precision of sand control 

        该防砂管的过滤元件是用精密数控机床加工的,并经激光检测,因此加工出来的滤片精细,成缝精度高,误差可控制在10±µm以内;滤片具有一定的厚度和强度,并且N个过滤芯片叠压在一起,因此在各种情况下都很难使它变形而影响防砂效果。

The filter element of the sand-proof tube is processed by a precision CNC machine tool and is laser-detected, therefore the processed filter is fine, the seam precision is high, and the deviation can be controlled within 10±μm. With a certain thickness and strength, by stacking N filter cores together, it is difficult to deform it in various cases to affect the sand-proof effect.

         三、过滤面积大,流通性好Large filtration area and good circulation  

        可根据油气田产能需要定制过流面积,每米有效过滤面积可达到基管表面积的4.3-9.2%,是普通割缝管的2-3倍,适应高产井的生产需求。

        The filtration area can be customized according to the oil and gas field production capacity. The effective filtration area per meter can be up to 4.3-9.2% of the surface area of the base tube, which is 2-3 times that of the ordinary slotted tube, and could meet the production needs of high-yield wells.

          四、自洁功能 Self-cleaning function

         自洁功能是由外窄内宽V字型缝隙结构决定的,且缝腔很光洁,所以小于缝宽的细粒粉砂或泥质很容易通过V字型缝隙,不会受阻停留缝隙中间而达到自洁;
The self-cleaning function is determined by the outer-narrow-inner-wide V-shaped slit structure, and the slit cavity is very smooth, so the small-grained silt or muddy which is smaller than the slit width can easily pass through the V-shaped slit and will not be blocked in the middle of the slit, achieving self-cleaning function.  
         大于缝隙宽度的砂挡在管外,在管外形成高渗透的“砂桥”,起到了管外砾石充填的作用。
Sand larger than the slit width is blocked outside the tube, forming a high-permeability "sand bridge", which acts as filling gravel outside the tube.
        五、适合高抗腐介质 Suitable for high corrosion resistance medium
        过滤件材质均选用优质的不锈钢材料,特殊井况选用特殊材质;
        滤片有一定的厚度,因此本产品具备很强的抗磨、抗压、抗高温、抗腐蚀能力;
The filter materials are all made of high quality stainless steel, and special materials are used for special well conditions. 
The filter has a certain thickness, so this product has strong wear resistance, pressure resistance, high temperature resistance, corrosion resistance ability;
        六、整体性好、强度高 Good integrity and high strength 
       基管采用符合API标准的加厚套管或油管;保护套和过滤片采用不锈钢氩弧焊双焊接在基管上,整个过滤件完全融入基管中成一整体,整体性很强;
Our products adopt API-standard thickened casing tubes or oil tubes. The stainless-steel protective jacket and filter are welded
onto the base tube with argon arc double welding technology. And the filter is thoroughly integrated inside the base tube.
      七、施工工艺简单,尤其适合水平井 Simple and convenient construction, especially suitable for horizontal Wells
      过滤单元件为内嵌式结构,管径小,表面光洁,下入阻力小,施工简单方便,尤其适合水平井与大斜度井作业。
The filter unit is an embedded structure with small tube diameter, smooth surface, low inserting resistance, simple and convenient construction, and is especially suitable for horizontal wells and high-slope wells.
