利用塔中4油田压力恢复资料、垂向干扰测试资料及产能资料的分析结果，结合其他静态资料（录井、取心、测井等资料），对该油田进行了早期评价。评价结果认为，该油田同一油组内油层物性相近，但各油组间差别较大；CI油组边界反映明显，横向延续性差，分布范围有限；CII油组油层物性变化大；CIII油组内除部分储层有边界反映外，主要反映的是在探测范围内呈无穷大均质地层特征，油层物性好，厚度大，分布范围较广，地层能量充分，有明显的垂向渗流特征，建议可选择水平井开采来改善油田开发效果。

An early evaluation is made in combination with other static data, such as logging, coring and well logging by using the analysis results of pressure buildup,vertical interference and productivity testings in Tazhong 4 oilfield.The result of evaluation shows that in the oilfield the physical properties of reservoirs within the same group are similar,but there exists bigger difference between groups.An obvious boundary response exists in group CⅠ,in which lateral continuity is poor and distribution range is limited.There is a big variation of reservoir physical properties in group CⅡ,in group CⅢ there exist boundary responses from some of the reservoirs,the main responses include that within the detection range the property of homogeneous formation is infinite,reservoir physical property is good,its thickness is big,distribution range is wide,productivity is high enough and in the reservoir vertical percolation character is obvious.It is proposed that horizontal well would be chosen to improve the efficiency of oilfield development.
