碳氢化合物化石燃料被认为是为工业目的提供足够能源的首选燃料。此外，从勘探威尔斯井中提取石油可能是未来几十年关注的问题，石油工程师们将自己推向极限，寻找新的解决方案来提高石油采收率。井筒增产措施对目前的增产效果有着深远的影响，在生产过程中，储层产能指数急剧上升，从而消除了其他方法的不必要支出。对酸化工艺的适当研究及其在井筒增产中的重要作用完全取决于添加剂的质量和类型、酸的类型、酸化操作和地层类型。本研究的目的是研究碳酸盐岩储层中注入酸的效果，并随后将其与酸化作业模型进行比较。因此，可用的试井实验管理，以确定关键的储层参数，如表皮系数，储层压力和渗透率。此后，通过在酸化施工模拟软件中模拟井筒条件，模拟酸化对储层的影响。因此，将来自软件的所提供的信息与来自试井操作的真实的数据进行比较。结果，由于成功的酸化程序，生产指数显著提高。
The hydrocarbon fossil fuels are considered as the preferable fuels to provide sufficient energies for industrial purposes. Also, extracting oil from the exploration wells might be a concerning issue in the coming decades, and petroleum engineers push themselves into limits ind novel solutions to enhance the oil recovery factor. Wellbore stimulation procedures exert a profound impact on the current production rate enhancement; respect of the way, reservoir productivity index witnesses a steep rise during the production operation and subsequently would virtually eliminate unnecessary expenditures of other methodologies. Appropriate investigation of acidizing procedures and its significant role in the wellbore production enhancement are utterly dependent on the quality and types of additives, types of acid, acidizing operation and types of formation. The objective of this study is to investigate the effect of injected acid in the carbonated reservoir and subsequently its comparison with the acidizing operations model. Therefore, available well-testing experiments are administered to determine the critical reservoir parameters such as skin factor, reservoir pressure, and permeability. Since then by modeling the wellbore condition in the acidizing operation simulator software, the impact of acidizing on the reservoir is simulated. Consequently, the provided information from software is compared with the real data from well-testing operations. As a result, productivity index is increased dramatically owing to successful acidizing procedures.
