Analysis on Chang 6 Channel System and Enrichment Laws of Oil Reservoirs in Zhidan Area

Zhidan area is one of oil and gas enrichment areas in the North Shaanxi slope zone. The study on Chang 6 reservoir found that deposition of channel sand body is the main factor affecting the reservoir. Therefore, according to Chang 6 channel system analysis and study on reservoir enrichment regularity, distribution of sand bodies was obtained as well as reservoir enrichment laws, which can guide the next well deployment and favorable target selection.
