二流量试井工艺及资料解释分析方法

Double Flow Rate Well Testing Techniques and Way of the Data Interpretation

描述了二流量试井工艺的实现 ,从常规分析和双对数曲线拟合两个方面 ,给出了二流量试井的资料解释分析方法 ,分析认为二流量试井同样可以计算出正常关井测压力恢复 (或压力降落 )资料所解释的油藏及流体参数。这种试井方法不但可以减少因正常关井测压对产油量和注水量的影响 ,而且可以减缓因突然关、开井造成的套管变形或损坏。实践证明 ,该试井技术方法具有较好的经济效益和应用前景。

The realization of double flow rate well testing techniques is descript in this paper and the way of well testing data interpretation is also provided from the normal analysis and double logarithmic curve. Through double flow rate well testing, the reservoir and fluid parameters can be obtained from the data interpretation of the pressure buildup or breakdown in normal shut-in. This kind of well testing can decrease the pressure testing effect to the oil production and water injection during the normal shut-in. In addition, it can also decrease the case pipe distortion and damage because of suddenly shut-in and well startup. Testified by practice, the double flow rate well testing can get a better economic benefit and application foreground.
