摘要
随着吐哈油田大部分井进入开采后期,流体关系复杂,使得产出剖面测井解释与油田实际生产解释相差很大,低产井产液剖面测井解释结果无法准确反映井筒内的产出状况。利用地面三相流模拟井实验装置标定仪器,将理论与现场实验相结合,研制出流量、含水率的解释图版,形成吐哈油田一种新的低产井产液剖面资料油水两相图版解释方法。利用图版解释方法进行定量解释,减小了井下流体因轻、重相之间的流速差异所带来的滑脱影响。在油田实际应用中,该解释方法得到的解释结果与实际情况相差很小,具有良好的应用前景。
As most of the wells in the Tuha oilfield enter the late stage of exploitation,the complexity of the fluid relationship becomes more and more serious,which makes the production profile based on logging interpretation very different from the actual production.As a result,the liquid production profile based on log interpretation of stripper well cannot accurately reflect production status.Using the ground three-phase flow simulation well experimental device to calibrate instrument,combining the theory with the field experiment,this paper develops the interpretation chart of the flow rate and water content.Based on that a new oil-water two-phase chart interpretation method for liquid production profile of stripper well in Tuha oilfield is established.According to the analysis of quantitative interpretation results from this method,it is found that the slippage effect due to the differences in flow rates between light and heavy phases decreases.In practical application,the result is very close to the actual production situation and has good application prospect.
