目前厚油层高含水后期由于储层描述相对较粗,水平井挖潜后,剩余油分布规律不清,挖潜技术相对单一,研究厚油层开发剩余油影响因素及分布规律,根据剩余油分布规律及控制因素,研究挖潜技术及水平井开发的相关技术政策,进一步提高油藏采收率,对于实现厚 Due to the relatively coarse reservoir description at the later stage of high water cut in thick oil reservoirs, the remaining oil distribution rules are not clear after tapping potential in horizontal wells, and the potential tapping technology is relatively single. The influencing factors and distribution rules of residual oil in thick oil reservoirs are studied. According to the remaining oil distribution rules and control Factors, research potential technology and horizontal well development of related technical policies to further enhance oil recovery, for the realization of thick
