特高含水期油藏经济极限产液量研究

摘要

我国大部分老油田已处于特高含水期开发阶段，提高产液量是保持稳产或减缓递减的重要手段。但特高含水期油藏受到地质、油藏、注水、工艺等限制，总体产液量水平偏低。本文综合确定了随油价波动的经济极限末产、经济极限含水、不同含水率下经济极限产液量等指标，为特高含水期油藏参数经济政策界限计算提供借鉴。%For most oilfields which are now under the development stage of ultra-high water cut,increasing the liquid- producing capacity plays an important role in keeping high yield or slowing down the decrease of yield. However,the general liquid- producing capacity stays on a low level due to the limitation of geology,oil field,water injection and technical processes. Based on the study of max liquid producing rate of the single well,the indicators including economical limited oil production rate and water cut,liquid production rate under different water cut rate,which fluctuate with petroleum price to provide reference for calculating economic policy limitation of ultra-high water cut oil fields parameters.
