摘要

利用统计分析方法研究了油层参数与压裂增产效果间的关系, 并对参数进行了无因次化处理, 开展了敏感性分析, 并将其结果应用到模糊决策。采用模糊综合评判方法, 建立了相应的数学及求解模型, 对油井(层)能否采取压裂作出定量判断。经七个泉油田压裂井实际数据进行计算验证, 方法可行, 从而为油田压裂选井选层提供了理论依据。

Abstract

By statistics and ana ly sis, the influence o f reservo ir
param eters on the incrementa l resu lt of fracturing we lls is
researched. By making the param eters d im ension less, the
sensitiv ity of these param eters is ana ly sed and then is applied
to fuzzy theo ry. U sing comprehensive identification fuzzy
theory, the m athem atical model and so lved m ode l are
established to de term ine the fractur ing m easu res
quantitative ly. Them ethod is feasible by testing and ver ify ing
using the data o f Q ig equan O ilfie ld, wh ich can prov ide a
theory founda tion for the optim ization o f fractured fo rm ation
