恒速压汞及核磁共振在低渗透储层评价中的应用

通过对渗透率的统计,重新认识和划分了宝浪油田宝北区块的主力层及非主力层。应用恒速压汞技术和核磁共振技术对宝北区块的储层物性进行了重新评价和划分。应用核磁共振技术对水驱油效率以及不同孔隙级别内流体的动用程度进行了研究,并从微观理论上对低渗透岩心中的大孔隙低采出程度、小孔隙高采出程度以及高渗透率岩心中的大孔隙高采出程度、小孔隙低采出程度进行了研究和解释,为油田的后续开发技术政策界限研究及开发认识提供了理论依据。

Application of constant-rate intruding mercury and nuclear magnetic resonance method to low permeability reservoir evaluation

Through the statistics of the permeability,the author again recognizes and classifies the main layer and non-main layer of the north block in the Baolang oilfield.The author uses the advanced constant-rate intruding mercury technology and nuclear magnetic resonance technology to evaluate and classify again the reservoirs in the north block.The author uses the nuclear magnetic resonance technology to research the water drive efficiency and the movable extent of the fluid in different pores.In the micro-economic theory,he researches and explains the low recovery degree of big pores and the high recovery degree of small pores in the low permeable cores,and the high recovery degree of big pores and the low recovery degree of small pores in the high permeable cores in order to provide a theoretical basis for researching and understanding the policy limits of the follow-up development technology.
