Abstract

Nowadays, the concentration of mineral cations and anions in the formation water of oil and gas fields is a challenging issue for oil industry technicians managing the formation of mineral deposits during water injection operations. For this reason, the analysis of formation water mineral ions during exploitation operations can be a valuable solution for the efficient management of oil production. Therefore, in this research, the thermodynamic and geochemical evaluation of formation water in the Reg-e Sefid oil and gas field is considered. Based on the results of this study, the formation of calcium sulfate and calcium carbonate can be expected due to the concentration of mineral ions dissolved in the formation water in the Reg-e Sefid oil and gas field according to the StimCad2 software. Also, based on the evaluation of ion ratios, the studied oil and gas field formation has ideal conditions for hydrocarbon production. Based on the results obtained from the comparison of the water and rock formation of the Rag-e Sefid oil and gas field, the source of ions (except calcium and magnesium ions) is related to ancient sea water.

伊朗拉格-塞菲德油气田地层水热力学与地球化学研究

目前，油气田地层水中矿物阳离子和阴离子的浓度是石油工业技术人员在注水作业中管理矿床地层的一个具有挑战性的问题。因此，在开采过程中对地层水中矿物离子进行分析可以为有效的石油生产管理提供有价值的解决方案。因此，本研究考虑了regg -e Sefid油气田地层水的热力学和地球化学评价。根据本研究结果，根据StimCad2软件，根据Reg-e Sefid油气田地层水中溶解的矿物离子浓度，可以预测其形成硫酸钙和碳酸钙。同时，根据离子比的评价，所研究的油气田地层具有理想的产烃条件。根据rage Sefid油气田水体与岩层对比结果，除钙、镁离子外，其他离子来源与古海水有关。
