High Resolution Sequence Stratigraphy

Using high-resolution sequence stratigraphy theory and its technology, based on 22 well cores and 4 256 logging data, interface types and characteristics of different grades the base-level cycle in Putaohua oil layer of Sanzhao Sag was systematically analyzed, and Putaohua oil layer is divided into 1 medium-term base level cycle, 4 short-term base level cycles, 8 super-short-term base level cycles, established high-resolution sequence strata framework, and proposed sequence stratigraphy model of middle super-short-term base level cycles meridionally grado-thin and up to vanish with syndepositional structure lifting control in the south of Putaohua oil layer. Sandstone is offlap Pinch-out in the upper of Putaohua oil layer, and Sandstone is onflap Pinch-out in the under of Putaohua oil layer from north to south.

With the instruction of the high resolution sequence stratigraphy and sedimentology theory, and the comprehensive application of 11 wells core, more than 800 mud logging and log data, high resolution sequence stratigraphic characteristics research in the XII Group of the Member III of Qing Shankou Formation in the Qianan oilfield has been finished. The results show that the study area can be divided into one middle-term base level cycle and five short-term base level cycles. The only sequence structure of middle term cycle is (B type) and the short term cycle mainly consists of B types meanwhile there are small mounts of upward deepening structures (A type) and symmetric structures (C type). Based on the classification of base-level cycles, fine stratigraphic correlation is conducted by using isochronous cycle correlations. In addition, 15 high resolution sequence stratigraphic frameworks are established which unify the study area and provide the solid geological basis for the sandstone distribution, the identification of mainly oil-bearing sand bodies and potential oil reservoirs.

High Resolution Sequence Stratigraphy

By using geological and geophysical data and according to the basic characteristics of sequence boundary, Putaohua Reservoir in Daan Oilfield is divided into a rise hemicycle in long-term cycles, a full middle-term cycle, nine short-term cycles and a number of ultra-short-term cycles.The high-resolution sequence stratigraphic framework of Putaohua reservoir under monosandbody rank is established, and a set of techniques and methods to high-resolution sequence stratigraphy correlation in shallow delta is summed up.

High Resolution Sequence Stratigraphy

With the method of the high resolution sequence stratigraphy and sedimentology theory, oil-bearing sand bodies have been accurately recognized and descripted which could provide precisely geological data for 3-D modeling and numerical simulation. It has the vital significance for the development of oilfield during the late stage of high water cut. According to the drilling, logging, seismic and analytical experiments data, the results show that the study area can be divided into one long-term base level cycle, four middle-term base level cycles, sixteen short-term base level cycles and twenty-eight super short-term base level cycles. Based on the classification of base-level cycles, control functions of cycles which have effects on the sediment environment have been discussed. And with the application of the chronostratigraphic correlation fine stratigraphic correlation, 10 high resolution sequence stratigraphic frameworks are established in the direction that is parallel and perpendicular to the source.

Filter Analysis

For a more accurate reservoir prediction of braided delta front, the method of High Resolution Sequence Stratigraphy was adopted in Moxizhuang Oil Field with the assistance of Comprehensive Prediction Error Filter Analysis. J1s2 was divided into 2 fifth-order base-level cycles, 5 sixth-order base-level cycles, with the turnaround surfaces of base-level rise to fall, and time-equal correlation of shallow braided delta front was achieved. Through study of microfacies correlation in High Resolution Sequence Stratigraphy frame, it is apparent that base-level cycles control microfacies distribution, and furthermore reservoir distribution: reservoirs around turnaround surface of base-level falling to rising are thick and laterally connected, while reservoirs near the middle of base-level falling and base-level rising are relatively thinner and less laterally connected, and reservoirs close to the beginning of base-level falling and the end of base-level rising are undeveloped.
