【摘要】：一点法试井具有测试时间短、工艺相对简单、成本低等优点,不仅减少了测试时的放空气量,而且能有效评价产能,故在气田产能评价中应用广泛,但各气田一点法产能公式中的α存在较大差异。为了将这一方法应用于阿姆河右岸S气田,对一点法产能公式进行了修正,建立了适于该气田的一点法产能公式。根据目前S气田42井次的产能试井成果,获取的S气田一点法产能公式中的平均α为0.28.但由于S气田单井产能差别较大,根据产能高低进行分类,求得不同产能范围内的α,应用气田平均α为0.28和按照产能高低进行分类取得的α的一点法产能公式计算产能,验证了采用产能区间划分后取得的α计算的无阻流量更加准确。
[Abstract]:One-point well testing has the advantages of short test time, relatively simple process and low cost. It not only reduces the amount of gas discharged during the test, but also can effectively evaluate the productivity, so it is widely used in the evaluation of gas field productivity. In order to apply this method to S gas field on the right bank of Amu River, the one-point productivity formula is modified. The one-point productivity formula suitable for the gas field is established. According to the results of 42 productivity tests in S gas field at present, the average 伪 of the one-point productivity formula obtained in S gas field is 0.28.However, the single well productivity difference in S gas field is quite large. According to the classification of productivity, the 伪 in different productivity range is obtained. The productivity is calculated by using the one-point productivity formula of the average 伪 of gas field 0.28 and the 伪 according to the classification of productivity. It is verified that the unobstructed flow rate calculated by using productivity interval partition is more accurate.
