致密砂岩气藏储层物性下限及控制因素分析
Methods to Determine the Lower Limits and Controlling Factors of the Effective Reservoir of Tight Sand Gas Reservoirs
摘要
Abstract
The tight sand reservoirs of the east of Sulige Area in Changqing Oilfield is typical of relatively lower porosity and much lower permeability in gas reservoirs area.Research of lower limit of reservoir set is the base for distinguishing effective reservoirs from non-effective ones.We have researched the lower limit of reservoir by several methods.The lower limits of effective porosity and permeability for reservoirs are determined by productivity simulation technique.On the basis of the research,the controlling factors of effective reservoirs are discussed.Our research indicates that the low limit of porosity and permeability is 4.0％～5.0％ and 0.075～0.100 mD,respectively.And the lower limit of gas saturation is 45％.The property of reservoirs in east Sulige Gas Field is mainly controlled by lithology and sedimentary microfacies.The mechanical compaction is the key factor which caused the porosity decreasing.Quality of sandstone reservoirs is controlled by the efficiency of corrosion and alteration.Thickness of sandstone has less influence on the reservoir effectiveness.关键词
