杭锦旗区块储层产水及气层有效性分析

Analysis of the Effectiveness of Reservoir Water Production and Gas Reservoir in Hangjinqi block

杭锦旗地区属于典型的低孔低渗致密砂岩储层。目前测试层位大多出水,进而影响气层产能。针对该区储层产水情况,从储层区域位置、岩性、物性、孔隙结构、含水饱和度及试采方式等方面对储层产水进行了分析,明确了储层产水原因,据此应用核磁测井资料及岩心实验资料对气层有效性进行了分析,取得了较好的应用效果,明确了气层中水的含量,进而可以为甲方提供合理施工建议,提高气层产能。

Hangjinqi area is a typical tight sandstone reservoir with low porosity and permeability.At present,most of the tested horizons can produce water,which affects the productivity of gas reservoir.According to the water production situation of the reservoir in this area,the water production of the reservoir is analyzed from the aspects of the location,lithology,physical property,pore structure,water saturation and test production mode of the reservoir,and the causes of reservoir water production are sorted out.Then the effectiveness of the gas reservoir is analyzed with the nuclear magnetic logging data and core experiment data,and the water content of the gas reservoir is clarified so as to provide reasonable suggestions to the construction for party A,which can improve the productivity of gas reservoir and achieve better effects.
