    Abstract: China’s cementing software is mostly imported, and the automation level of cementing equipment is low. As a result, the cementing information management capabilities is insufficient. Therefore, in order to solve these problems, this paper studied the multi-equipment collaborative control method and the whole-process flow automatic monitoring method, and developed a major new automatic monitoring cementing equipment to achieve a multifunctional and integrated cementing system (AnyCem®). As a result, a novel automatic cementing technology was formed, and a whole-process automatic cementing operation was achieved. Further, the technology has been applied in 85 wells in Liaohe Oilfield and Changqing Oilfield as well as Southwest and North China oil and gas fields, with the construction parameter monitoring accuracy rate reaching 100%. Furthermore, the cement slurry density control accuracy is 0.01 kg/L, and the cement head gate and valve operation can be completed within 2s, with the cementing operation accuracy improved by more than 80%. Research and applications show that through the integrated software and hardware interaction, the automatic cementing technology based on the AnyCem® system has achieved the prediction of complex cementing situations, the control of the cementing process, and the assurance of high cementing quality. In addition, it has achieved scientific cementing design and accurate operation and thus can efficiently support complex deep and unconventional oil and gas resource exploration and development.
