复杂裂缝性双重介质储层有效厚度划分方法——以克拉玛依油田车47井断块和573井区块二叠系佳木河组油藏储层为例

以车47井断块和573井区块二叠系佳木河组油藏裂缝性双重介质储层为例介绍了确定裂缝性双重介质储层有效厚度的方法。首先通过岩性判别，排除非储集性岩性，在此基础上采用以经测试已得到证实的油层、千层（水层）的单层测试为依据，用费歇（fisher）判别法求得反映储层储渗能力的集总参数来确定有效厚度下限标准，用测井计算的多种参数（裂缝孔隙度、孔隙度和含油饱和度）建立有效厚度判别模型，并进行有效厚度划分。运用该方法，近年来在准噶尔盆地多个区块储量复算中，进行了有效厚度的划分，证明结果是可靠的。

THE INTERPRETATION METHOD OF NET-PAY LAYER OF COMLICATED DUAL POROSITY RESERVOIR

Take the che 47 wells fault blocks and 573 wells sub-areas jiamuhe group oil deposit crack dual medium reservoir as an example,an effective thickness determinative method of crack dual medium reservoir is introduced.First step is through the lithological character to remove the non-accumulation lithological character.On the tasis of tested layers,the Fisher law is used to figure out the total parameters which can reflect the ability of reservior infiltration so as to determine the effective thickness low,limit standard.With many kinds of oil well logging computation parameters(fracture porosity,porosity and oil aturation), the effective thickness distinction model has been established.In recent years, Using this method,the oil and gas reserves in the Zhungaer Basin many sub-areas reserves have been recalculated,the effective thickness division has been carried out.The result is proved reliable.
