Jin 150 Block Of Injected Water With Reservoir

Block Jin-150 is a low permeability water-sensitive reservoir.In view of thecharacteristics such as the block developing on natural energy,the fast drop of formationpressure and the low recovery ratio,some methods have been taken in order to make moreeffective development Once hydrocarbon reservoir damage occurs,the development effects will be affected directly.Hydrocarbon reservoir protection should bepaied more attention especially for low permeability reservoir.This paper studied the main cause for hydrocarbon reservoir damage.Associated with the reservoir geology of Jin150 block in Jinzhou oil production factor,core analyses are made,and meanwhile,sensibility evaluation of this block are made.According to the evaluation results,when injection,operation,acid treating,fracturing and other application,injecting fluid must coordinate with formation,clay inhibitor should be selected,in order to prevent reservoir from damage.To the reservoir that damage has existed,some release technologies are applied.The hydrocarbon reservoir protection technologies are applied to guide the development of Jin 150 block and make better results.
