Fluid components in cores are crucial parameters in evaluating the quality of a shale reservoir in both laboratory analyses and log interpretation. In the Gulong area, shale reservoirs are characterized by a high clay content, with clay spaces hosting both oil and water phases, complicating the occurrence mechanism of fluid components, as a result, traditional research methods are no longer applicable. As an advanced technique, nuclear magnetic resonance (NMR) has been applied in oilfields to determine the specific petrophysical properties of rocks. To more accurately identify the types of fluid components, this study carried out a new, well-designed 2D NMR experiment, rock pyrolysis experiment, and quantitative oil and water detection experiment (QOWDE) to study the Gulong shale. This study measured the 2D NMR map of the original state, saturation state, centrifugal state, and pyrolysis at different temperatures, and conducted mutual verification between the QOWDE and 2D NMR pyrolysis experiments to obtain the distribution of different components of Gulong shale on the 2D NMR map. Based on the experimental results, this study developed a component identification template suitable for the Gulong area and calculated the 2D NMR porosity and saturation from it. This lays a foundation for the analysis and application of fluid components in the Gulong region and provides a new experimental basis and methodological support for porosity and saturation calculations.

The operation and management mode of “Internet+ Logistics Park” ecosphere has long-term and stable core competitiveness. This paper studies how to obtain the corresponding economic benefits from the perspective of the operators of the logistics park. The logistics park chooses the appropriate logistics service and the public service function to obtain the corresponding economic benefit. The development of the logistics park will finally be implemented to the profit of the park. The paper puts forward the profit model of “Internet+ Logistics Park” ecosphere; This paper mainly analyzes five modes: logistics integration mode, platform operation mode, resource integration mode, service delivery mode and chain replication mode; This paper makes a comparative analysis of different profit models from the aspects of model characteristics and profit thinking.

Since the State Council issued the “Plan for the Adjustment and Revitalization of the Logistics Industry” in 2009, the logistics industry, as the basic and strategic industry in the development of the national economy, has played an increasingly important role in promoting industrial transformation and upgrading and promoting economic development. In order to promote the development of logistics industry, a large number of logistics parks have been built all over the country under the guidance of policies and the promotion of the market. However, after the construction of these logistics parks has been put into operation, There are a series of problems in its development and profit. This paper analyzes the present situation and profit of logistics park in China, and briefly analyzes the main business characteristics of freight hub, production service, port service, trade service and comprehensive service. On this basis, the main problems existing in the existing profit model of logistics park in China are summarized.

The port competition is more and more intense, starts to be the initial infrastructure and the operation ability competition, now is in the port economy hinterland competition. Dry Port has the functions of customs declaration, forwarder, inspection and quarantine, warehousing, loading and unloading, circulation processing etc. At present, the construction and layout of the inland dry port, the possibility and feasibility of construction are the focus of the research. The location of dry port in Jinan is fully analyzed on the basis of reference to the advanced operation mode and development experience of the excellent non-water port in the country and abroad. This paper first analyzed Location factors; Then center of gravity method were analyzed. Finally, the location of the dry port is determined.
