A Study of Solid-Free Drilling Fluid for Tight Gas Reservoirs

引用

Open Journal of Yangtze Oil and Gas 2021年第1期6卷 13-23页

作者： Wenwu Zheng Fu Liu Jing Han Binbin He Xintong Li Qichao Cao Sinopec North China Petroleum Engineering Co Ltd. Zhengzhou China Yangtze University Jingzhou China

This project is explaining a laboratory development of a solid free drilling fluid formula that could be potentially used in tight gas reservoirs. The configuration of the weak gel fluid WGL-1, which is resistant to high temperature and high salt, was tested, and concluded that its gelling properties, salt and temperature resistance, and environmental protection were all in line with industry requirements. The final drilling fluid formula was developed as: water + (0.3% ~ 0.5%) NaOH + 5% KCl + 2% WGL-1 + 5% NaCl + (1.0% ~ 2.0%) HBFR Anti-high temperature fluid loss agent + 2% Polyol + (1.5% ~ 2.0%) SDL-1 Lubricant + 0.4% A4O1. The performance of the liquid was tested for temperature resistance, inhibition, gas formation protection effect, plugging performance, and static settlement stability. It was concluded that the temperature resistance performance is satisfied at 150°C, and the cuttings recovery rate is as high as 96.78%. It has good performance in inhibiting water dispersion and swelling of cuttings. The permeability recovery value reaches 88.9%, which meets the requirements of gas formation protection. The SSSI value shows that its settlement stability is good;under high temperature and high pressure, its sealing performance is good. This drilling fluid system has achieved the expected results and laid a foundation for further promoting the development of solid-free drilling fluid systems. The future development direction of solid-free drilling fluids is pointed out, to the improvement of properties to be applied in high temperature environment and have high salt resistance capacity.

绿色、可持续发展已成为当今科技的主题,天然环保油墨的研究是印刷领域凸显该主题的重要课题。然而,传统天然颜料大豆油基环保型油墨存在耐温性差的缺点。本文打破了传统天然颜料大豆油基油墨不能用于高温、加热食品及包装印刷的局限。研制实用型耐温天然颜料大豆油基环保油墨具有重要现实意义。本文引入有机硅,并充分利用其Si-O键的键能121千卡/克分子,在高温下（或辐射照射）分子的化学键不断裂、不分解特性实现油墨耐高温性能。实验选用二甲基硅油、甲基三甲氧基硅烷、乙烯基三甲氧基硅烷和氨丙基三乙氧基硅烷试剂作为油墨的耐温试剂,以红色油墨为例,分析不同温度下不同组油墨的色密度、光谱反射率,探究油墨对高温的敏感性,以便提高其实用价值。实验表明,二甲基硅油与大豆油混合时,发生交联反应,生产白色絮状物,影响实验继续进行。随温度的升高,以甲基三甲氧基硅烷、乙烯基三甲氧基硅烷、氨丙基三乙氧基硅烷作为耐温试剂的油墨,初步表现耐温性:油墨的色强、灰度、色效率均在合理范围内变化,油墨的光谱反射曲线波动较小。氨丙基三乙氧基硅烷除可作为耐温试剂外,还具备调色剂的功用。
