Study On The Reservoir Description And The Experiment Of Infilling Adjustment In The Songfangtun Oil Field

There are six blocks that have been taken into production in Songfangtun oil field. Due to long-termproduction, the oil field have come into medium-high water cut period. Moreover undergoing many wellpattern adjustments, injection adjustments, fracture and other measures, all blocks' adjustment effect arebecoming poor. So it is necessary to carry on a comprehensive adjustment which takes infill adjustment asa core.Through evaluating Songfangtun oil field's geology feature and development effect, the main factorswhich influence different blocks' production effect are found. Aiming at existed main problems, anobjective and effective infill adjustment project is made.Through analyzing six blocks reservoir and geology feature, reservoir detail description anddevelopment effect, referencing Songfangtun pilot area and Shengping oil field well pattern inflll effect,combining F708 block's numerical simulation result, basing on comprehensive analysis and research, F507,F17 and F6 blocks of Songfangtun oil field are chosen to be carried on well pattern infill adjustment,Zhusan and Songfantun pilot areas don't take this measure temporarily.Take economic benefit as center, through a comprehensive adjustment which takes infill adjustment asa core., we can perfect injection-production relation, change seepage direction, enlarge sweep efficiency,improve water drive control degree and reservoir recovery rate. So the purpose of improving blocks'development effect and increase recoverable reserves can be reached. It can also provide an adjustmentbasis for similar type block's treatment.
