Abstract: Low oil prices forced shale oil and gas cost to decline sharply in a short period of time. This fact makes us realize that cost-effectiveness of oil and gas operation has been downplayed for a long time. The profit sourcing from high oil prices, to a large extent, has weakened the initiative for cost reduction by means of technological progress. From the angle an enterprise, the main factors influencing cost-effective objectives include corporate development strategy and collaboration for business management in addition to engineering services. Therefore, it is necessary to regard costeffectiveness as the fundamental principles of an enterprise, which should be implemented at various levels and in different links, thus strengthening collaborative innovation of the whole industrial chain and restructuring system at the industrial and State levels. In face of energy structural optimization and the new round of industrial and technological revolution at the present time, we should meet the new challenges on the basis of revolutionary innovation of oil and gas technology.
