Abstract

Asphaltene precipitation can result in several production, operational, and transportation problems during oil recovery. If asphaltene precipitates and deposits, it can reduce reservoir permeability, damage wellbore equipment, and plug the pipelines. It is therefore extremely important to evaluate the conditions at which asphaltene precipitation occurs; this is referred to as the asphaltene onset pressure. Asphaltene onset pressure has been measured using many different experimental techniques. There have also been many attempts along the years to predict asphaltene onset pressure using mathematical correlations and models. This research provides an up-to-date comprehensive review of the methods by which asphaltene onset pressure can be measured using laboratory experiments and mathematical models. The research explains the main mechanisms of all the laboratory experiments to measure asphaltene onset pressure under static conditions and how to conduct them and highlights the advantages and limitations of each method. The research also provides a summary of the commonly used mathematical models to quantify asphaltene onset pressure directly and indirectly.

沥青质起始压力测量和计算技术:综述
在采油过程中,沥青质沉淀会导致一些生产、操作和运输问题。如果沥青质析出并沉积,会降低储油层的渗透性,损坏井筒设备,堵塞管道。因此,评估沥青质析出的条件极为重要,这被称为沥青质起始压力。沥青质析出压力的测量采用了多种不同的实验技术。多年来,也有很多人尝试使用数学关联和模型来预测沥青质析出压力。本研究全面回顾了利用实验室实验和数学模型测量沥青质起始压力的最新方法。研究解释了在静态条件下测量沥青质起始压力的所有实验室实验的主要机制以及如何进行这些实验,并强调了每种方法的优势和局限性。研究还总结了直接和间接量化沥青质起始压力的常用数学模型。
