Abstract:
The subsea channel sand and sheet sand, in the west of Daqing placanticline, play the most important role in the oil layer of Putaohua. The sand reservoir has the characteristic of chare distribution, 1-3 m thick, which varies fast horizontally . So the prediction of sand reservoir by seismic has a limit of resolution. Therefore the reservoir evaluation and development has a risk of uncertainty. In order to improve the prediction accuracy of thin narrow sand body, taking Gulong oilfield as an example, we created the stepwise well-seismic joint tracking inversion. The method is based on petrophysical response characteristic analysis, optimizing inversion method and parameters. Continuously increasing rolling well numbers, by optimizing and adjusting five batches 161 development wells, the prediction accuracy of sand body is increased continuously, which ensures the effect of preliminary development plan of the oilfield. A set of rolling prediction and adjusting workflow is developed, which can be popularized and applied.
Key words: thin and interbedded sand-shale reservior, seismic response, reservoir prediction, plan conduct
