Calcium carbonate scale is a problem in many industrial and domestic processes, as it precipitates from solution to form a hard deposit which grows on equipment surfaces. The potential for scale formation and aggregation is present whenever a solution becomes supersaturated. Scale formation and prevention creates a considerable capital, operation and maintenance problem. Achieving effective and economical scale control and removal is consequently a major concern for efficient and safe industrial operations. To prevent such potential problems, it is important to understand the mechanism of the calcium carbonate scaling process.

This paper is part of the continued effort to understand calcium carbonate formation and mitigation related to oilfield operations. The paper describes the application of a new method, based on laser refraction measurement in transferring the signals to current, to determine the formation of calcium carbonate scale in high calcium brines. This method provides a real-time measurement of the magnitude of scaling crystals, and has been proven to be a sensitive method to monitor the initial stages of the precipitation process. This study focuses on the comparison between two techniques to evaluate formation and aggregation of scale in the presence and absence of scale inhibitors at different temperatures. Also, the efficiency of laser technique will be assessed as an effective tool for the scale and aggregation inhibitors performance and ranking, where the results will be compared with the offline measurement technique using a static test method.

碳酸钙水垢在许多工业和家庭过程中都是一个问题，因为它从溶液中沉淀形成硬质沉积物，并在设备表面生长。每当溶液变得过饱和时，都可能形成水垢形成和聚集。结垢和防止结垢会产生大量的资金，运营和维护问题。因此，实现有效和经济的规模控制和清除是有效和安全的工业运营的主要关注点。为防止此类潜在问题，重要的是了解碳酸钙结垢过程的机理。

本文是继续努力以了解与油田作业有关的碳酸钙形成和减缓的一部分。本文介绍了一种基于激光折射测量的新方法在将信号传输到电流中的应用，以确定高钙盐水中碳酸钙垢的形成。该方法可实时测量结垢晶体的大小，并且已被证明是监测沉淀过程初始阶段的灵敏方法。这项研究的重点是在两种温度下在存在和不存在阻垢剂的情况下评估结垢形成和聚集的两种技术之间的比较。此外，激光技术的效率将被评估为衡量阻垢剂和聚集抑制剂性能和等级的有效工具，
