SPC技术在致密油储层预测方法优选中的应用OA

This paper focuses on the optimization of tight oil reservoir prediction methods,aiming to improve the accuracy and reliability of tight oil reservoir prediction by introducing statistical process control(SPC)technology,and provides a scientific basis for oil and gas exploration and development.Given the complexity and uncertainty of tight oil reservoirs,traditional prediction methods face many challenges,making it difficult to ensure the stability and reliability of the resulting predictions.For this reason,this paper proposes an optimization scheme of a tight oil reservoir prediction method based on SPC technology.This scheme uses SPC technology to monitor and analyze the prediction process in real time.By comparing the accuracy and stability of different prediction methods,the optimal combination is selected.In the application of this scheme in the Fuyu reservoir in the northern Songliao Basin,the overall coincidence rate of reservoir prediction reached 86.6%on average,and the coincidence rate of sand body prediction greater than 3 m reached 87.8%.This technology offers a new approach to the exploration and development of tight oil reservoirs and has broad application prospects and significant promotional value.
