【摘要】：渤海A区油田是国内目前已发现的规模最大的中生界花岗岩潜山油气田。由于潜山复杂多样、横向非均质性强,传统的测井曲线标准化很难满足EI反演对测井数据的要求。为了进一步提高测井数据精度,本文提出了一种分区带测井曲线标准化方法:首先根据研究区地震断块构造空间解释,结合测井解释结果,将工区合理划分为不同的标准化区带,然后采用均值校正法进行分区带标准化。在渤海A区油田的EI反演中对比未标准化、用常规方法标准化和分区带标准化的反演结果,发现分区带标准化方法得到的反演剖面与地震剖面对应最好。在渤海A区油田进行分区带测井曲线标准化是获得合理、准确的EI反演结果的关键。
[Abstract]:Bohai area A oil field is the largest Mesozoic granite buried-hill oil and gas field found in China at present. Because of the complexity and diversity of buried hill, transverse heterogeneity is strong. The traditional logging curve standardization is difficult to meet the requirements of ei inversion for logging data, in order to further improve the accuracy of logging data. In this paper, a method of standardizing the logging curve of the zonal zone is proposed. Firstly, according to the spatial interpretation of the seismic fault block in the study area and the result of the log interpretation, the working area is reasonably divided into different standardized zones. Then the mean correction method is used to standardize the zonal zone. The inversion results of the conventional method and zonal zone standardization are not standardized in the ei inversion of the oilfield in Bohai A area. It is found that the inversion section obtained by the standardization method of zonal zone corresponds best to the seismic profile, and the key to obtain reasonable and accurate ei inversion results is to standardize the logging curves of the zonal zone in the oilfield of Bohai Sea area A.
