摘要:
 

为快速准确估算气井产能，以渗流力学理论为基础，根据单探针MDT测试过程中的渗流特点，建立单探针MDT球形流渗流数学模型，通过拉氏

变换等方法求解模型，对单探针MDT试井曲线的特征及参数敏感性进行分析，提出应用单探针MDT试井解释结果计算探井产能的新方法。应用该方法对南海东部某口探井进行了

产能计算，结果为148×104 m3/d，与DST实际测试结果176×104 m3/d，相差159%，能满足对产能评价的需要。该方法可以部分代替DST 测试，大幅度降低勘

探成本，提高勘探效益。

Abstract:
 

In order to quickly and accurately estimate the gas well productivity, based on the theory of

percolation mechanics, according to the percolation characteristics of single probe MDT testing, the mathematical model of single probe MDT

spherical flow percolation is established. The model is solved by Laplace transform and other methods, and the characteristics and parameter

sensitivity of single probe MDT testing curve are analyzed. A new method is proposed to calculate the productivity of exploration

wells by using the interpretation results of single probe MDT well test. The productivity of an exploration well in the east of South China Sea is

calculated by this method, and the result is 148×104m3/d. Compared with DST actual test result 176×104m3/d. The difference is 159%,

which can meet the needs of capacity evaluation. This method can partly replace DST test, greatly reduce exploration cost and improve exploration

benefit.
