摘要
由储量行业分类标准可以看出,技术可采储量由证实储量、次经济可采储量和累积产油量构成。中国石油行业标准中计算蒸汽吞吐稠油油藏技术可采储量的方法是注采关系曲线法,油汽比的确定是应用该方法的关键。若引入经济参数,采用经济极限油汽比即可计算证实储量。以曙光油田杜229块为例,其计算结果与SEC储量评估方法计算结果对比,相对误差为4.96%,符合石油行业标准,证实了该方法的适用性和可行性。该方法对其他油田有一定的借鉴意义。
From industry classification standard for reserves,it can be seen that technical recoverable reserve is constituted of the proved reserves, time economically recoverable reserves and cumulative oil production. In China 's oil industry standard,method of calculating steam stimulation technically recoverable reserves of heavy oil reservoirs is from injection curve,determination of the ratio of oil and gas is the key step. If economic parameters are introduced,using the economic limit of oil and gas can calculate proved reserves ratio. In the Du229 block of Shuguang oilfield,for example,compared of the calculation results with the SEC reserves calculated results,the relative error is 4. 96%,meeting the oil industry standards,and the applicability and feasibility of the method is confirmed. This method has some reference to other fields.
