老井复查评价技术在浅层油藏中的研究与应用

本文以靖安地区浅层老井为例,利用钻井、录井、测井、取心等资料,结合现代测井解释评价技术,对受当时技术条件限制被误判的储层进行再分析研究.制定可行的复查评价标准与流程,确定出油下限,优选补孔潜力井,并结合精细地质研究成果筛选建产目标区,达到挖潜增效和滚动增储的双重目的.对老区日后寻找新储量进行勘探开发具有十分重要的意义.

Study and application for evaluating technology of old well reexamination in shallow reservoirs

The misinterpreted reservoirs,because of the limitation of technical conditions at that time were re-examined by use of drilling,logging,coring and other data and combined with the modern well logging interpretation and evaluation,by the example of old wells in shallow reservoirs of Jing'an area.Feasible reexamination and evaluation standards and processes was established,lower limit of oil production was determined,the potential wells were suggested,favorable areas were optimized combining with the results of fine geological studies in order to increase the reserves,tap out the potential and improve the benefit.It is of great significance for the exploration and development of new reserves in the old area in the future.
