应用修匀—递减法标定老区水平井可采储量
We take the controlling of the pressure decline rate in low pressure area,the controlling of the pressure build-up rate in high pressure area as a principle.
通过采取以上措施,该区不但未发生新的成片套损,而且平均钻1口井仅影响产量115t,自然递减为7。
If wells produce at natural productivity,their flow rates decline with the same speed as the mid-and high-permeability reservoirs.
若油井以自然产能生产,油井产量的递减速度并不快,而是与中高渗透储集层基本相同。
Using the steam huff and puff temperature field, saturation field result and the in-situ monitoring data of high temperature steam intake and liquid-producing profiles, well temperature profile, the primary factors that the super-heavy crude single well convention steam huff and puff high cycle decreases progressively are analyzed.
以辽河油田曙一区超稠油油藏为例,利用蒸汽吞吐温度场、饱和度场拟合结果及高温吸汽剖面、产液剖面、井温剖面等现场监测资料,分析了超稠油单井常规蒸汽吞吐高周期递减的主要因素。
Based on the mechanism of GM(1,1),we give a method of improving the monotone decreasing sequence in grey modeling.
本文基于 GM(1,1)模型的建模机理,提出一种针对单调递减数据列建立灰色模塑的新方法, 首先对单调递减的原始序列 x~((0))(k)作变换 y~((0))(k)=x~((0))(1)-x~((0))(k)+c;然后对所得序列 y~((0))(k)做对数变换 y_1~((0))(k)=ln y~((0))(k),最后建立 GM(1,1)模型。
