Abstract

Tight oil is one of the important substitute areas of the oil industry in China. The effective development of tight oil is of great significance for the development of China's economic sustainable and stable. Changji tight oil of Xinjiang oilfield is a typical Chinese blocks of tight oil, it has the characteristics of high viscosity and low mobility. With reservoir numerical simulation method, based on the historical fitting of tight oil production data in Changji oilfield, Xinjiang, The author have calculated and analyzed the formation factors, engineering factors and fluid factors of the tight oil production. The results show that the SRV volume of the fracturing, the spacing of the fracturing section and the size of formation matrix created by network fracture are the main parameters that affect the initial productivity of tight oil. The SRV volume, the formation pressure coefficient and the viscosity of crude oil are the main parameters that affect the cumulative production.
