摘要
常规的地层因数劈分方法在实际应用中存在着一定的局限性,其适用性将直接影响到研究结果的精度和可信度。介绍一种新的产量劈分方法,以产液剖面数据为基础,通过数据挖掘方法,找出影响单层产出量的关键因素,并通过试凑法建立多参数的产量劈分方程,以提高精度。用该方法在准噶尔盆地石南21井区对块状砂岩油藏的产量劈分过程中,计算出的数据与实际情况符合度较高,应用效果较好。与常规方法相比,该方法具有精度高,运用方便,实用性强等特点,可以较好地解决块状砂岩油藏的产量劈分问题。
The conventional formation coefficient splitting method had certain limitations in practical application,its serviceability directly affected the accuracy and reliability of the study results.A new method of production splitting was presented.It was based on fluid production profiles,through data mining,the critical factors influencing the single layer production were found out,the trial-and-error method was used to establish an equation of multiple parameter production splitting to improve its accuracy.It is used for production splitting in the blocky sandstone reservoirs of Wellblock Shinan 21 in in Junggar Basin,the calculated result is well coincided with actual application and good result is obtained.Compared with conventional production splitting method,the new method has high precision,it is easy to use and has high practicability.It can be used to well solve the problem of production splitting in blocky sandstone reservoirs.
