Accumulation History

The quantitative grain fluorescence and quantitative grain fluorescence on extract have become effective approaches in the analysis of hydrocarbon evolution in clastic reservoirs recently. The cutoff threshold for differentiating current/paleo-oil and water zones is crucial to reconstruct accurately hydrocarbon accumulation history. However, the absence of theoretical study on the cutoff threshold in the carbonate reservoir has precluded their application and development. In this paper, we attempted to investigate the cutoff threshold by analyzing the quantitative grain fluorescence and quantitative grain fluorescence on extract parameters and spectra of the cores and natural carbonate outcrop samples in known current/paleo-oil and water zones revealed by the frequency of oil inclusions, formation test, logging analysis, etc. Based on this, the hydrocarbon charging history of the Suqiao Buried-hill Zone, Bohai Bay Basin, eastern China was reconstructed using the gotten threshold. Results show that the carbonate minerals fluorescing will lead to a higher cutoff threshold of quantitative grain fluorescence index value in the carbonate reservoir, while the threshold of quantitative grain fluorescence on extract intensity value is coincident with the corresponding value in the clastic reservoir. The quantitative grain fluorescence and quantitative grain fluorescence on extract data have unraveled a complicated hydrocarbon accumulation history in Suqiao Buried-hill Zone including oil charging before gas and paleo-oil loss due to the tectonism. The ascertained cutoff threshold in this study is of great significance for reconstructing accurately and effectively the complicated hydrocarbon charging history in the carbonate reservoir, which provides significant models for future petroleum exploration.

Different Parts

The reservoir in different parts of buried-hill draping zone is often quite different, so it is of great significance to clarify the reservoir characteristics for exploration and development. Based on core, well logging, seismic data and production data, reservoir characteristics of oil layer Ⅱ in the lower second member of Dongying Formation of L oilfield, Bohai Bay Basin, offshore eastern China are systematically studied. Analyses of seismic facies, well-seismic combination, paleogeomorphology, and sedimentary characteristics are carried out. Sediment source supply, lake level and buried hill basement geomorphology all contribute to reservoir quality. The research suggests that the different parts of buried-hill draping zone can be divided into four types. Reservoir thickness and physical properties vary. The area where the provenance direction is consistent with the ancient valley direction is a favorable location for the development of high-quality reservoirs. Under the guidance of the results, oilfield production practices in L oilfield offshore China are successful. Knowledge gained from study of L oilfield has application to the development of other similar fields.
