摘要
开发层系细分与重组是有效提高层状砂岩油藏采收率的重要手段,细分与重组开发层系要求有一定的储量规模。利用谢尔卡乔夫公式从单位面积最大收益和单井控制可采储量两个角度,研究了开发层系细分与重组的储量丰度技术经济下限,得到了相同的数学模型,其影响因素有储层物性、流体物性、投资成本、生产成本和原油价格;它与单井投资成正比,与吨油利润(原油价格与吨油生产成本之差)成反比,油层物性和流体物性越好,它越低。该方法也可用来确定新区动用的储量丰度技术经济下限。应用实例表明,该方法简便、实用、可靠。
The subdivision and recombination of development layer series were an important method for improving recovery of multi-layered effectively.It required certain amount of reserves scale.By using XIE formula and from the aspects of maximum revenue unit area and controllable single-well reserves,the technical and economical low limit of the reserve abundance for the subdivision and recombination of development layer series were studied and similar mathematical models were obtained.The influence factors included reservoir physical properties,fluid properties,investment cost,production cost and crude oil price.These are in direct proportion with investment and inverse proportion with oil profit/ t.The better the reservoir physical properties and fluid properties are,the low ratio it should be.This method can be also used to determine the lower limit of reserves abundance to be developed.The applications show that the method is simple,practical and relible.
