Evaluation Of Jilin Oilfield Yingtai Post Exploration Project

The natural geographical location of exploration project of YingTai South JiLin Oilfieldbelongs in DaAn County Jilin province.The exploration area which is in the north of NengRiver is apart of DaQing Oilfield;DaAn Oilfield is in the south of it and HongGang Oilfieldis in the southwest. Regional structural location is in the middle of DaAn-HongGang Terracecentral depression area south part of Songliao Basin which is in the west of western slopezone,in the east of GuLong sag.Based on DaAn Oilfield and HongGang Oilfield, this blockhas superior geographical and economic conditions.Since2009,there are total57exploration wells drilled, footage of12.3976×104m;complete investment of307,470,000yuan about exploration. In which,it has completed13preliminary prospecting wells, footage of2.7105×104m and preliminary prospectinginvestment of77,180,000yuan;the number of appraisal wells is44, footage of9.6871×104m, completing investment230,290,000yuan of reservoir evaluation. The submission ofoil geological reserves is6148×104t, oil controlled geological reserves is5504×104t,proven oil geological reserves of5103×104t,oil recoverable reserves is1041×104t,completing102.5%,100.1%,127.6%and127.6%of the program respectively.This paper mainly evaluates exploration project of South YingTai systemicly from theproject decision-making deploy, drilling, exploration benefit, environmental impact andsustainability, and draws the corresponding conclusions.Also,It summarizes the experienceand lessons in the implementation of the project and puts forward improving suggestion forthe future which has important significancei n JiLin Oilfield exploration work.It provides thetheory basis and technical support for exploration of other blocks in Jilin Oilfield.
