浮子流量产液剖面解释评价技术研究

Research on Evaluation Technology of Floater Flow Production Profile

随着吐哈油田深层稠油的深入开发,油田迫切需要了解油层的产出状况。为了进一步服务油田,提高解释水平,根据浮子流量响应原理和非对称响应特征,将浮子流量运动分为增量和减量两个阶段,通过分析浮子流量在两个阶段不同的响应特征,应用二项式拟合方法,分阶段建立浮子流量解释图版。所建立的解释图版与标定数据更加吻合,在稠油产液剖面测井评价中取得了较好的应用效果。

With the deep exploration of heavy oil reservoirs in Tuha oilfield,it is urgent to understand the output status of the oil reservoir.In order to further serve the oil field and improve the interpretation level,according to the floating flow response principle and asymmetric response characteristics,the floating flow movement is divided into two stages: increment and reduction. The floats flow interpretation charts in different stages are established by means of binomial fitting method according to the different response characteristics. The established interpretation chart is more consistent with the calibrated data,and achieves better application effect in logging evaluation of heavy oil production profile.
