摘要(Abstract)：

以气水两相渗流理论为基础,从岩心测试资料出发建立井口综合数据、小层数据以及小层流体饱和度之间的回归关系,求取气井生产任意阶段的合采层段各小层的相渗,并结合相渗进行产量劈分。该产量劈分方法避免了传统方法只靠静态参数无法考虑动态变化影响和不能识别开发过程中储层特性变化的弊端。实践证明:该方法与气藏开发资料结合更加紧密,可以较好地解决薄互层砂岩气藏的产量劈分问题,具有较高的准确性和较强的操作性。
Based on gas and water phrase percolating theory,from the viewpoints of the core and tested data,the regression relationship are established among the comprehensive wellhead and individual layer data and fluid saturation of the single layers,the phase permeabilities of each layer in the commingled intervals are obtained in each production stage of the gas wells,and furthermore combined with the phase permeabilities,the productions are split.The splitting method has remedied the defects that the traditional method only uses static parameters and can't consider the dynamic performances and moreover identify the changes of the reservoir characteristics in the course of the development.The practice shows that the approach can well solve the production spilt problem of the thin and interbedded sandstone gas reservoirs,closely combine with the gas reservoir development data and moreover more concisely and feasibly put into practice.
