Production and Sand Control Completion Laboratory(PSCCL)  is a research and education team working on oil and gas filed sand control and solid management. The team is a union of vigour and vitality, as well as creativeness. The team belongs to School of Petroleum Engineering, China University of Petroleum. For many years, we’ve been concentrating on the subject of oil/gas field development, and mainly the job of sand control completion. PSCCL focus on oil and gas production engineering, sand production and sand control, water control,  solid control and management, concerning basic theories, technologies, methods, equipment and software.The research area of PSCCL covers loose sandstone, unconventional oil and gas, deep carbonate, coalbed methane, natural gas hydrate, thermal well, underground gas storage. The head of PSCCL is professor Changying Dong. The team includes 1 professor, 1 vice professor, 3 young teachers and more than 20 postgraduates. PSCCL construct united laboratory with CPOE and COSL.

PSCCL is equipped with series of experimental apparatus involving sand production simulation, sand control optimization, sand carrying simulation, fracpack well stimulation, integrity evaluation. the laboratory employs apparatus more than 20 installations with 300 m2.  The laboratory has the full ability to accomplish the experiments on sand control and fluid-solid management.

PSCCL has already accomplished 6 National 863 projects and National Nature Science Fund projects, and over 120 enterprise projects from the start. The theory and method of systematic oil and gas well sandcontrol prediction has been brought up. At the same time, oil and gas well sandcontrol compositive decision-making method and technology system has been constructed properly, which contains sandcontrol decision make, parameter optimization, horizontal well gravel packing and sanding well productivity prediction and evaluation. Moreover, we’ve build up systematic compositive decision-making platform of oil and gas well sand control-- Sandcontrol Office. It has been popularized in many oilfields at home as well as international oilfields. Till now, we have achieved 6 provincial awards for scientific and technological advancement, more than 10 awards of Bureau level. 

PSCCL has published 7 monographs on sold control and management, concerning "Sand Control Technologies in Oil and Gas Wells"、“Theories and Technologies on Sand Control in Oil and Gas Wells","Theories and Technologies on Sand Control in Horizontal Wells", et al.  PSCCL also published technical articles more than 120 items, and retrieved by SCI/EI more than 60 items.PSCCL was authorized 20 China patents, and 16 software. All of the work improves the development of sand control and solid management in China.

◆ Education and Training

---

We have published 7 monographs which are Oil and Gas Well Sandcontrol Technology, Oil and Gas Well Sandcontrol Theory and Technology and Sandcontrol completion theory and technology of Horizontal Well. At the same time, we have open a subject named Oil and Gas Well Sandcontrol Theory and Technology in China University of Petroleum (East China). On the other hand, a systematic oil and gas well sandcontrol experiment laboratory has been well constructed. With abundant scientific research, a complete education system is conducted in a good manner. Based on these conditions, sandcontrol education and research job has been promoted significantly, and Professor Dong Changyin has been awarded as Excellent Young Teacher in Colleges and Universities by Huo Yingdong Education foundation in 2012.
