在采油操作中,专用于清除生产油管中石蜡沉积物的处理费用或用于抑制石蜡沉积的挤注处理费用是颇为可观的,如果进行上述处理使生产层顶损坏,油田减产,那么所需要的费用就会进一步增加。我们的研究表明,通过使用一种被称为“分散剂”的表面活性剂,是可以防止或大大延缓石蜡的沉积。现有两类专用的表面活性剂可选用,它们用作石蜡分散剂已证明是非常有效的。一类是油溶性的,另一类是水溶性的。分散剂可以连续注入油井或按规定的时间间隔大量加入,实行间歇处理。选用间歇处理还是连续处理的方案取决于需要处理的油井类型和数量。
In oil recovery operations, the cost of treatment dedicated to the removal of paraffin deposits in the production tubing or the cost of squeeze treatment to inhibit the deposition of paraffins is considerable, and if the above treatment results in damage to the production head and a reduction in production on the field, The cost will be further increased. Our research shows that it is possible to prevent or substantially delay the deposition of paraffin wax by using a surfactant called “dispersant”. Two types of specialty surfactants are available, and their use as paraffin dispersants has proven to be very effective. One is oil-soluble and the other is water-soluble. Dispersant can be continuously injected into the well or a large number of time intervals to join, the implementation of intermittent treatment. The choice between intermittent or continuous treatment depends on the type and number of wells that need to be treated.
