Title: FAN DEPOSIT CHARACTERISTICS OF SHAHEJIE FORMATION IN SHENGTUO AREA OF DONGYING DEPRESSION
Abstract: Various fan deposits such as fluvial fans, coastal subaquatic fans and turbidity fans were developed in Es\-3 and Es\-4 deposition periods in Shengtuo area of Dongying Depression. The reservoir forming and distribution rules of above mentioned fans were analyzed comprehensively, according to the sedimentation and reservoir features. Fluvial fans developed in Es\-4 deposition period were characterized by conglomerate and gravel bearing sandstone formation. These fans often developed anticlinal and block reservoirs, and sandstones near faults have good reservoir properties. Coastal sub aquatic fans often developed in early period of Es\-3 deposition were characterized by conglomerate and gravel bearing sandstone formation. The mid fan often developed structural lithologic hydrogen pool with the best reservoir property. Turbidity fans developed in the middle period of Es\-3 deposition were characterized by sandstone formation showing good reservoir property and thin sand bodies, and the lenticular body and updip wedge out reservoirs were often developed.
