正逆累积法和分布函数法在研制储层电性标准中的应用

Application of the positive and negative cumulation method and the distributing function methods to research the electric standard of reservoir

针对储层电性标准研制时采用的交汇图法——单一的"L"型划分方法存在的不直观性和人为因素的影响,将正逆累积法和分布函数法首次应用到确定电性标准图版中,并以喇嘛甸油田气顶区为例,进行了气砂(含气砂岩)电性标准的研制.误差统计表明,两种划分方法均达到了国家储量规范的要求.这使得电性标准划分更加合理、精确与直观,为储层电性标准的研制提供了新的方法与思路.

Aiming at studying the electric standard of reservoirs by intercrossed chart , which is a single partition method of ＇L＇ type with unintuitionistic and artificial influence, we use the positive and negative cumulation and the distributing function methods to research the electric standard of reservoirs. Taking the Lamadian oilfield as an example, we research the eletric standard of gas layers. Error statistics indicate that the two methods have all attained the request of national reserve criterion. So it makes the electric standard more logical, exact and intuitionistic, which provides the new approach and idea for development of the electric standard of reservoirs.
