考虑吸附和扩散的页岩视渗透率及其与温度、压力之关系
Factors influencing the productivity of fractured horizontal wells in the tight gas reservoir of eastern Sulige Gasfield and the optimization of them
摘要
Abstract
The staged fracturing of horizontal wells is the effective stimulation measures of tight gas reservoir. There are many factors influencing the productivity of the fractured horizontal wells, including geological factors and technological factors ( that is, the parameters of the fractured horizontal wells). Under different geological conditions, the effects of technological factors on the productivity are different. The factors influencing the productivity of fractured horizontal wells in the tight gas reservoir of eastern Sulige Gasfield are analyzed,and the main factors are found. Based on these,the optimization charts of the fractured horizontal well parameters under different geological conditions are obtained. The results show that, with the reservoir permeability becoming low and anisotropy becoming strong,the optimal horizontal section and the optimal fractured fracture of the horizontal wells will be longer,and the optimal space between fractures will be less. The effects of the factors on the productivity are correlative. The research results in this paper can provide guidance for the optimization of the fracture parameters of the staged fracturing horizontal wells in the tight gas reservoir.关键词
