近日，华东油气分公司首次在延川南煤层气田W75平台气井储层改造中应用自动加砂系统。该公司于2023年自主研发这一系统，并在页岩油大规模储层改造中成功应用。该系统的加砂效率较传统吊装方式提升近3倍，并可取代吊装登高作业，提升本质安全水平，大幅降低施工费用。

Recently, East China Oil & Gas Company applied the automatic sand addition system in the reservoir reconstruction of W75 platform gas well in Yanchuan South coalbed methane field for the first time. The company independently developed the system in 2023 and successfully applied it in large-scale reservoir reconstruction of shale oil. The sand adding efficiency of the system is nearly 3 times higher than that of the traditional hoisting method, and it can replace the hoisting and climbing operation, improve the essential safety level, and greatly reduce the construction cost.
