东风港油田测井精细解释模型研究与应用

Fine Log Interpretation Model Study of DONGFENGGANG Oilfield and Its Application

东风港油田车44区块油水分布复杂,储层物性在平面上的变化主要是受沉积微相控制,沉积微相在平面上变化。从区块物性纵向对比分析,层间非均质不强,层内非均质较强。从常规的分层位建立解释模型都不理想,针对该特点建立了分沉积相带的孔隙度、渗透率解释模型。其模型相关系数较高,相对误差较小,建立了RT与声波时差的交会的识别图版,给出判断油水层的电性、物性标准。将所建立的模型应用到FORWORD解释平台中,处理结果经构造和试油验证,适合实际地质情况。

The oil and water distribution of CHE 44 block in DONGFENGGANG oilfield is complex. The changes of reservoir physical property are controlled by the sedimentary microfacies changed in plane. According to the portrait contrastive analysis of the block physical property, we can see that the interlaminar anisotropic isn＇t strong but the intraformational heterogeneity is stronger. For the traditional horizon interpretation model is inaccuracy, the porosity and permeability interpretation model of different sedimentary facies belt is founded in this paper. The correlation coefficient of the model is higher, and the relative error is smaller. In this paper, it also founds the identify plate about RT and SDT, presents a discriminate standard about the electrical property and physical property of the oll and water layer. The model is used into FORWORD. The processed results verified by the structure and the test oil, accords with the practice geologic aspects.
