永3断块开发效果评价

永安油田永3断块为一多油层、中高渗透复杂断块油藏，1996年以来年产能力迅速下降，2003年采油速度只有0．28％。2004年对该断块进行了综合研究，对水驱效果、储量动用状况、井网状况、能量状况进行了全面、深入地评价，明确了存在问题和开发潜力，编制了综合调整方案，实施后取得了很好的开发效果，对同类油藏的开发具有一定的指导意义。

The Evaluation of the Droduction Effect in Yong 3 Fault Block

Yong 3 fault block of Yongan oilfield is multi oil layer and higher permeability complex reservoir. The annual producibility decreased rapidly after 1996 and petroleum production rate is only 0.28 percent in 2003. The problem and development potential is assured by the comprehensive research and the evaluation about the flooding effect, the reserves employing status, well network adaptability and energy of the block. The better effective is achieved by means of the comprehensive adjusting scheme drafted out and implemented, which has the guidance meaning to the same kind of reservoir.
