摘要
岩性夹层和物性夹层在陆相沉积中非常普遍,通过岩性和物性特征识别取心井夹层,根据不同夹层的测井响应特征识别非取心井的夹层,并按照一定的标准剔除,能更加合理地确定有效厚度,精细表征油藏地质特征,取得客观的储量数据。
Interlayers are often present in sandstone oil reservoirs.Whether or not eliminating the interlayers in estimating the oil reserves will give very different calculation results.Lithologic and physico-property interlayers are widely found in continental sediments. Interlayers in core well and in non-core well are identified respectively by lithologic and physical-property characteristics and logging characteristics. Eliminating the interlayers according to certain standards will ascertain the effective thickness of reservoirs more reasonably, and describe geological characteristics of the reservoir more delicately, so as to get more objective reserves.
