欢127东块地堑油井受油层发育不均、物性差、井况差等因素影响,采出程度较低,剩余油富集。针对井区北部油井井况差的矛盾,优选欢127-20-29(大修)、欢127-21-30c(侧钻)两口油井,措施初期见到较好效果,进一步验证了井区存在较为富集的剩余油。下步将继续采取大修、侧钻等措施恢复油井产能。并针对井区中部区域油层发育较好油井,实施分注合采措施复产,提高井区油井利用率。
Huan 127 east block graben oil wells affected by uneven development of the reservoir, poor physical properties, poor well conditions and other factors, the recovery of the lower, the remaining oil enrichment. In view of the contradiction between well conditions in the north of the well, the two wells, Huan 127-20-29 (overhaul) and Huanhuan 127-21-30c (sidetrack), were found. The preliminary results showed good results and further verified the existence of well Rich remaining oil. The next step will continue to take overhaul, sidetracking and other measures to restore oil well productivity. In the middle part of the well area, well-developed oil wells are well developed.
