摘要
本文在分析油田合理井网密度影响因素、非均质多油层油田井网密度与水驱最终采收率关系的基础上,导出了油田加密调整井的经济极限井网密度的求解方法。对喇、萨、杏油田各大纯油区和过渡带在完善一次加密调整后,进一步加密调整可行性及二次加密井网的经济合理界限和经济极限井网密度进行了计算、分析。指出了油田二次加密调整的有利地区,给出了不同价格体系下,二次加密井的数量界限。
<ABSTRACT> Based on the analyses of the influential factors of reasonable well density, the relationship between well density of multi-zone reservoirs with he terogeneity and ultimate recovery by watcrflooding, and the solving process of economic limits of well density in infilling wells is deduced Calculation and analyses of reasonable economic limit and economic limit well density alter the first infill adjustment and feasibility of further infill adjustment and secondary well density in net oilbearing area and transitional zone of Lamadian, Sacrtu & Xingshugang reservoirs is made and points out favourable areas of secondary infill adjustment in the field.Quantitative limit of secondary infill wells under different price systems is given.
