苏里格气田苏xx区块天然气储层具有孔隙度低,渗透性差,低阻气层与高阻气层并存的特点,由于地层骨架对测井信息的贡献远大于天然气对测井的影响,增大了储层物性和含气性的解释难度。本文利用岩心分析化验资料,建立了孔隙度、渗透率等测井解释方程,绘制了测井解释图版,研究了天然气的识别方法,并在实际工作中得到了验证,取得了良好的效益。
The natural gas reservoirs of the Su-xx block in the Sulige gas field have the characteristics of low porosity and poor permeability, and the coexistence of low gas barrier and high gas barrier. Because the contribution of the formation skeleton to logging information is far greater than that of natural gas logging, Increased reservoir physical and gas-containing interpretation of the difficulty. In this paper, the logging interpretation equations of porosity, permeability and so on are established by using core analysis and laboratory data. Well logging interpretation charts are plotted, natural gas identification methods are studied, and the verification is made in practical work. Good results have been obtained.
