ANALYSIS ON THE FACTORS INFLUENCING THE GAS WELL PRODUCTIVITY OF S2 GAS POOL IN PERMIAN OF ZIZHOU GAS FIELD
摘要
Abstract
Due to the complex geological condition and changeable productivity, there are many factors effect on the productivity in low porosity and low permeability reservoir. It is difficult to predict productivity. Aiming at this problem and based on the data of sixteen wells of s2 gas pool of Zizhou gas field, 10 factors affecting the productivity are selected by using open flow potential as a evaluation index of the gas well productivity. Then we found the key factors by using the methods of grey slope relational analysis, principal component analysis and R cluster analysis. Although there are some differences in the key factors, effective thickness, gas saturation, storage coefficient and formation coefficient are in front. Finally comprehensive analysis indicates that the key factors effecting on the gas well productivity of the reservoir include effective thickness, gas saturation, storage coefficient and formation coefficient. This conclusion has some directive significances for wells and layers selection, fracturing design and fracturing operation.关键词
