Abstract

One of the most serious complications in the production, transport and treatment of oil is asphaltene-resin-paraffin deposits. Their formation in underground well equipment, as well as in flow lines, collection system pipelines increase the cost of oil production. There are no sufficiently effective reagents to solve these problems. The results of implementation in many other wells testify to the high efficiency of the new reagent. The effect of reagents on the rheological properties of oil was also studied. Sangachal Deniz oil was used as a crude oil sample. We have developed multicomponent and multifunctional reagents M-R, P-R. In addition, due to paraffin formations in the tubing, they had to change 50–60 pipes for new ones every month. As a result of the introduction of M-R reagents, no paraffin deposits were found in the tubing for almost a year The effect of these reagents on the pour point of oils, dispersion, dissolution, and paraffin deposition has been studied. The use of the new reagent was tested at the mines of the oil and gas production department (OGPD) "28 May". The results of implementation in many other wells testify to the high efficiency of the new reagent. The effect of reagents on the rheological properties of oil was also studied. Sangachal Deniz oil was used as a crude oil sample. The proposed three-parameter Herschel-Bulkley model can be used to assess the rheological parameters of oils during their transportation. This layer, of course, cannot thicken indefinitely. Highly effective multicomponent composite compositions were developed to combat complications in the production of high-asphaltene-resin-paraffin oils. As can be seen from, during the reagent dosing period, there were no particular changes in the well performance. Treatment with hot oil on certain days was, as it were, of a preventive nature, since no changes were observed in the well parameters before and after heat treatment. When a certain layer thickness is formed in the tubing, the linear velocity of oil increases and begins to wash it away

开发一种对抗蜡沉积的新技术

在石油的生产、运输和处理中最严重的问题之一是沥青质-树脂-石蜡沉积物。它们在地下井设备以及输油管线、采油系统管道中的形成，增加了石油生产的成本。没有足够有效的试剂来解决这些问题。在许多其他井的实施结果证明了新试剂的高效率。研究了试剂对油的流变性能的影响。Sangachal Deniz油作为原油样品。我们已经开发了多组分和多功能试剂M-R, P-R。此外，由于油管中有石蜡，他们每个月不得不更换50-60根新的油管。由于引入了M-R试剂，在近一年的时间里，油管中没有发现石蜡沉积。研究了这些试剂对油的倾点、分散、溶解和石蜡沉积的影响。在石油和天然气生产部门(OGPD)的矿山中对新试剂的使用进行了测试。“5月28日”。在许多其他井的实施结果证明了新试剂的高效率。研究了试剂对油的流变性能的影响。Sangachal Deniz油作为原油样品。提出的三参数Herschel-Bulkley模型可用于评估油品在运输过程中的流变参数。当然，这一层不可能无限增厚。为了解决高沥青质-树脂-石蜡油生产中的复杂问题，开发了高效的多组分复合成分。从图中可以看出，在药剂加药期间，井况没有发生特别的变化。在某些日子用热油处理，可以说是一种预防性质，因为在热处理前后没有观察到井参数的变化。当油管中形成一定厚度时，油的线速度增加并开始将其冲走
