Reservoir oiliness prediction is one of the important contents of reservoir description.The method of cluster analysis is used to identify oil,gas and water layers from well logging data.The prediction of oil reservoir is to obtain logging data at the well location and identify the oil content of the reservoir,so as to obtain an accurate understanding of the reservoir at a well location,which can make the identification more objective and obtain a complete understanding of the reservoir.In addition,selecting a suitable algorithm for attribute extraction can improve the accuracy and efficiency of the method.Therefore,this paper will focus on the identification of oil content in petroleum reservoirs based on K-Means cluster analysis.
This research uses uncertainty and sensitivity analysis methods on the mixed refrigerant refrigeration process,obtaining the range of energy consumption under the change of various input parameters and the influence of each parameter on energy consumption,providing guidance for the analysis of mixed refrigerant refrigeration processes.With the help of Python optimization algorithms,the process parameters were optimized,and the minimum energy consumption after optimization was 28497.74 kW.

Exploring and promoting the integration and development of ecosystems and industrial models between petrochemical enterprises and industries such as Beidou and geographic information is a necessity for industry and industrial development,Establishing an enterprise level geographic information platform system is a requirement for petrochemical enterprises to achieve high-quality development and intelligent manufacturing.
After more than ten years of exploration,domestic offshore oil field technology service companies have formed their own models of offshore fracturing supported by vessels.The enhancement ships mainly based on mild integration have problems such as limited capacity,long operation time,and non-standard operation site,etc.which have limited the development of the technology services.This article compares the main parameters of multi-functional production enhancement ships,and combines the relevant characteristics of mature PSV s to propose the selection and supporting scheme of future moderately integrated multi-functional production enhancement ships,as well as the concept of expanding the supply of proppants.It also briefly analyzes the main design of highly integrated production enhancement ships in China.
