深入探究青化砭油田长2储层四性关系,对研究区以后的新井解释和开发方案设计提供重要依据。通过收集青化砭油田的录井、岩心、测井、分析化验和试油生产等资料,建立了岩性、物性、含油性、有效厚度、测井参数等相关下限标准,区分油、水和干层。结果认为,长2油层的岩性、物性、含油性以及测井参数的有效厚度下限标准为:电阻≥10%;声波时差≥233μs/m,且在拐点处必须满足RT>-0.136 4 DT+47.091;K>1.0×10-3μm2;Φ>10%;So>37%。
In-depth exploration of the relationship between the four reservoirs of the Chang 2 reservoir in Qinghua Oilfield provides an important basis for the interpretation and development of new wells in the study area. By collecting such data as logging, core, well logging, laboratory analysis and test oil production in the Qinghua Oilfield, the lower limit standards of lithology, physical property, oiliness, effective thickness and logging parameters were established to distinguish oil, water and oil Dry layer. The results show that the effective lower limit of lithology, physical property, oil content and log parameters of Chang 2 reservoir are: ≥10% resistivity; Acoustic wave time difference ≥233μs / m, and RT> -0.136 4 DT + 47.091; K> 1.0 × 10-3 μm2; Φ> 10%; So> 37%.
