Patent number: 10458218Abstract: A method of modeling hydrocarbon flow from a fractured unconventional reservoir, where the formation has variability in stimulated reservoir properties caused by multi-stage fracturing treatment. A map is created which divides the formation into a plurality of closed production regions, each of which in turn is divided into a plurality of flow sub-systems extending between fractures in the formation. Production behavior is then calculated for each flow sub-system based on the geography and characteristics of the individual flow sub-system. Region hydrocarbon flow for each closed production region is determined by coupling the calculated production behavior of the flow sub-systems and the reservoir hydrocarbon flow can be modeled by aggregating the region hydrocarbon flows. Type curves showing the modeled hydrocarbon flow at selected points in time can then be plotted.Type: GrantFiled: December 22, 2015Date of Patent: October 29, 2019Inventors: Xiangzeng Wang, Ruimin Gao, Fanhua Zeng, Shanshan Yao, Hong Liu, Quansheng Liang

Patent number: 10282385Abstract: A method for the estimation of oil recovery factor in a foam flooded hydrocarbon reservoir. The hydrocarbon reservoir is divided into three sweep sub-zones, with sweep efficiency and displacement efficiency for each zone being estimated. The oil recovery factor is determined as a function of porous volume injected, based on the sweep efficiency and displacement efficiency.Type: GrantFiled: December 22, 2015Date of Patent: May 7, 2019Inventors: Xiangzeng Wang, Shubao Wang, Ruimin Gao, Yongchao Yang, Fanhua Zeng, Jun Yang, Yizhong Zhang

Patent number: 10099931Abstract: A method for directly preparing an empty shell type small grain ZSM-5 molecular sieve. The method comprises: uniformly mixing and stirring an organic template agent, a silicon source and water; dripping an aqueous solution of an aluminum source into the mixture; preserving room temperature, and continuously stirring for a period of time; and performing hydrothermal crystallization, and washing, drying and roasting the obtained product to obtain the molecular sieve. The molecular sieve has high degree of crystallinity and uniform particle size. Moreover, the method requires short time, simple operation and only one step, no extra surfactant is needed, and secondary acid and alkali treatment is not needed.Type: GrantFiled: July 14, 2015Date of Patent: October 16, 2018Assignees: RESEARCH INSTITUTE OF SHAANXI YANCHANG PETROLEUM (GROUP) CO., LTD., DALIAN UNIVERSITY OF TECHNOLOGYInventors: Jiuchang He, Wei Zhang, Xiongfu Zhang, Dapeng Li, Ruimin Gao, Yongbin Lu, Shuqin Zhang, Mingfeng Wang, Pengju Huo, Si Li, Yuan Zhang, Zhiling Liu, Gang Chen, Ting Pei, Hua Zhang

Publication number: 20170175493Abstract: A novel method for the estimation of oil recovery factor in a foam flooded hydrocarbon reservoir. The hydrocarbon reservoir is divided into three sweep sub-zones, with sweep efficiency and displacement efficiency for each zone being estimated. The oil recovery factor is determined as a function of porous volume injected, based on the sweep efficiency and displacement efficiency. The method provides good results with higher certainty, at a higher rendering speed and using less input data, than conventional numerical simulation approaches.Type: ApplicationFiled: December 22, 2015Publication date: June 22, 2017Inventors: Xiangzeng Wang, Shubao Wang, Ruimin Gao, Yongchao Yang, Fanhua Zeng, Jun Yang, Yizhong Zhang
