Concurrent Design Study of the Petroleum Equipment CAD System

Military petroleum equipment, as the special device a nd tool for petroleum storage, transportation, filling, chemical analysis, detec tion and maintenance for the army, is an important means and basis of petroleum indemnificatory. To adapt to modern war in high-tech conditions, the petroleum equipment have to develop towards higher reliability, adaptability, maneuverabil ity, standardization, container and cell type with versatile multi-functions. As a new design theory and design process, concurrent engineering may prod uce remarkable benefit when applying to product development. With the aid of the state-of-the-art modeling and simulation technology, it foresees the future or even the whole life cycle of the products designed. Based on wide statistics and survey, the product design period is reduced by 1/2～1/3 with concurrent des i gn process. The application of concurrent design process in new petroleum equi pment development shall greatly accelerate the petroleum equipment updating an d promote their indemnificatory.

Practice and understanding of developing new technologies and equipment for green and low-carbon production of oilfields

The core of China’s low-carbon development includes optimization of industrial structure,clean energy technologies,emission reduction technologies,and innovation of relevant systems and institutions.China National Petroleum Corporation(CNPC)has always been a proactive participant in developing low-carbon economy,shouldering the responsibilities of safeguarding oil and gas supply,conserving energy,and reducing emission.Therefore,CNPC fulfills those responsibilities as a substantial part of its overall strategy.Guided by low carbon and driven by innovation,petroleum corporations have taken constant innovation of low-carbon technologies,especially the development of green and low-carbon petroleum engineering technologies and equipment,as major measures for energy conservation and emission reduction.Large-scale development mode o f unconventional resource anhydrous fracturing should be innovated.And supercritical C 02 should be used to replace water for fracturing operation,in order to achieve multiple objectives of C 02 burying,conserve water resource,improve single well production and ultimate recovery,realizing reduced emission and efficient utilization o f C 02 resources.Artificial lifting energy-saving and efficiencyincreasing technologies and injection-production technology in the same well should also be innovated.Energy consumption of high water-cut wells is reduced to support the new low-carbon operation mode of high water-cut oilfields and realize energy saving and efficiency improvement during oil production by developing the operation efficiency of the lifting system and reducing the ineffective lifting of formation water.These technologies have been widely recognized by local and international experts and have greatly enhanced CNPC's international influence.This study expounds the key technologies and equipment with regard to the development of green and low-carbon petroleum engineering and provide relevant suggestions.
