This work investigates the efficacy of a biodegradable natural product, litchi leaves powder (LLP) as a filtration loss control agent in the water-based drilling fluid formulations. In order to evaluate the potential of litchi leaves powder (LLP), a strict protocol of experimentations according to API (American Petroleum Institute) standard has been followed. The experimental outcome showed that before hot rolling and after hot rolling of mud samples at 100 °C it was observed that 3–5% Concentration of LLP significantly increased the rheological parameters such as PV, YP and gelation of drilling fluid as compared to reference mud. Also, LLP reformed the filtration loss control characterization, suggesting a better biodegradable fluid loss reducing agent. After hot rolling at 100 °C for 18 h, the water-based drilling fluid with LLP as an additive showed a marked reduction in filtration control property as compared to reference Mud (RM). Experimental results concluded that 5% concentration of LLP significantly reduced the filtration loss of drilling fluid by 70.6% as compared to reference mud under the influence of 100 psi pressure. However, the conventional fluid loss additive CMC (LVG) reduced the filtration loss by maximum 67.5% as compared to reference mud. Therefore, LLP can be used as an alternative to CMC (LVG) in water-based drilling fluid with a maximum subsurface temperature of 100 °C.

这项工作研究了可生物降解的天然产物荔枝叶粉（LLP）在水基钻井液配方中作为过滤损失控制剂的功效。为了评估荔枝叶粉（LLP）的潜力，已遵循API（美国石油学会）标准的严格实验规程。实验结果表明，与参考泥浆相比，在100°C的泥浆样品热轧前和热轧后，发现LLP浓度为3-5％会显着提高流变参数，例如PV，YP和钻井液胶凝。此外，LLP还改进了滤失控制特性，表明了一种更好的可生物降解的滤失量降低剂。在100°C下热轧18小时后，与参考泥浆（RM）相比，以LLP为添加剂的水基钻井液的过滤控制性能明显降低。实验结果表明，在100 psi压力的影响下，与参考泥浆相比，浓度为5％的LLP可使钻井液的过滤损失显着降低70.6％。但是，与参考泥浆相比，传统的降滤失剂CMC（LVG）最多可将过滤损失降低67.5％。因此，在最大地下温度为100°C的水基钻井液中，LLP可用作CMC（LVG）的替代品。在100 psi压力的影响下，与参考泥浆相比为6％。但是，与参考泥浆相比，常规的滤失添加剂CMC（LVG）最多可将过滤损失降低67.5％。因此，在最大地下温度为100°C的水基钻井液中，LLP可用作CMC（LVG）的替代品。在100 psi压力的影响下，与参考泥浆相比为6％。但是，与参考泥浆相比，常规的滤失添加剂CMC（LVG）最多可将过滤损失降低67.5％。因此，在最大地下温度为100°C的水基钻井液中，LLP可用作CMC（LVG）的替代品。
