Abstract

The presence of hydrogen sulfide (H₂S) in oil and gas reservoirs is very problematic during well development stages. The carryover of this extremely toxic gas with the drilling fluid and its subsequent release at the surface could expose working personnel to substantial health and safety risks. Further, H₂S is very corrosive, and its contact with metallic infrastructure could lead to severe corrosion issues and the subsequent failure of these units. To mitigate these safety and operational risks, it is very necessary to incorporate additives with high and effective H₂S scavenging performance into drilling fluid formulations. Herein, we synthesized CuMgFe-layered triple hydroxide (CuMgFe-LTH) and investigated the effects of incorporating this nanomaterial into aqueous drilling fluids on their rheology, filtration loss, and H₂S removal performance. The synthesized CuMgFe-LTH was characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), nitrogen adsorption-desorption measurements, and thermogravimetric analysis (TGA). The obtained results indicate that the CuMgFe-LTH is compatible with the typical constituents of the formulated aqueous drilling fluid. More importantly, the addition of this nanomaterial provided an excellent H₂S scavenging performance, as it was able to scavenge about 216.3 and 268.0 mg H₂S/g LTH (corresponding to 2325.2 and 2881.0 mg H₂S/L mud) at breakthrough and saturation, respectively. Furthermore, the incorporation of these CuMgFe-LTH improved the apparent and plastic viscosities, yield point, carrying capacity, and gel strength of the drilling fluid. In addition, the base as well as the LTH-containing drilling fluids exhibited desirable pseudoplastic (i.e., shear thinning) behaviour, and curve-fitting analysis proved that the Herschel-Buckley model best fits the rheological behaviour of these muds. This further indicates that the addition of the LTH provides favourable rheological properties. To the best of our knowledge, none of the published studies on drilling fluids reported in the literature have investigated the utilization of any LTH or even any LDH (layered double hydroxide), highlighting the significance and novelty of the present work.

含cumgfe层状三氢氧化物的含水钻井液：流变性、滤失和H2S清除性能

在油井开发阶段，油气储层中硫化氢（H2S）的存在是一个非常严重的问题。这种极具毒性的气体随钻井液的携带以及随后在地面的释放可能会使工作人员面临重大的健康和安全风险。此外，H2S具有很强的腐蚀性，它与金属基础设施的接触可能导致严重的腐蚀问题，进而导致这些装置的故障。为了降低这些安全和操作风险，在钻井液配方中加入具有高效清除H2S性能的添加剂是非常必要的。在此，我们合成了cumgfe层状三氢氧化物（CuMgFe-LTH），并研究了将这种纳米材料掺入含水钻井液中对其流变性、滤失和H2S去除性能的影响。采用x射线衍射（XRD）、傅里叶变换红外光谱（FT-IR）、扫描电镜（SEM）、氮吸附-解吸测量和热重分析（TGA）对合成的CuMgFe-LTH进行了表征。结果表明，CuMgFe-LTH与配制的含水钻井液的典型组分是相容的。更重要的是，该纳米材料的加入提供了出色的H2S清除性能，在突破和饱和时分别能够清除约216.3和268.0 mg H2S/g LTH（对应于2325.2和2881.0 mg H2S/L泥浆）。此外，这些CuMgFe-LTH的掺入改善了钻井液的表观粘度和塑性粘度、屈服点、承载能力和凝胶强度。此外，基液和含lth钻井液表现出良好的假塑性（即剪切变薄）行为，曲线拟合分析证明Herschel-Buckley模型最适合这些泥浆的流变特性。这进一步表明LTH的加入提供了良好的流变性能。据我们所知，文献中没有任何关于钻井液的已发表研究报告调查了任何LTH甚至任何LDH（层状双氢氧化物）的利用，这突出了本研究的重要性和新见性。

期刊介绍： The journal includes papers in the following areas: – Simple organic liquids and mixtures – Ionic liquids – Surfactant solutions (including micelles and vesicles) and liquid interfaces – Colloidal solutions and nanoparticles – Thermotropic and lyotropic liquid crystals – Ferrofluids – Water, aqueous solutions and other hydrogen-bonded liquids – Lubricants, polymer solutions and melts – Molten metals and salts – Phase transitions and critical phenomena in liquids and confined fluids – Self assembly in complex liquids.– Biomolecules in solution The emphasis is on the molecular (or microscopic) understanding of particular liquids or liquid systems, especially concerning structure, dynamics and intermolecular forces. The experimental techniques used may include: – Conventional spectroscopy (mid-IR and far-IR, Raman, NMR, etc.) – Non-linear optics and time resolved spectroscopy (psec, fsec, asec, ISRS, etc.) – Light scattering (Rayleigh, Brillouin, PCS, etc.) – Dielectric relaxation – X-ray and neutron scattering and diffraction. Experimental studies, computer simulations (MD or MC) and analytical theory will be considered for publication; papers just reporting experimental results that do not contribute to the understanding of the fundamentals of molecular and ionic liquids will not be accepted. Only papers of a non-routine nature and advancing the field will be considered for publication.
