Sabei development area of Daqing oil field adopts the affiliating techniques based oncross-disciplinary studies of petroleum in field practice at sabei block, meeting a series ofproblems. To solve them, the author applies the achievement on fine geological study with thehelp of organic combination of multi-discipline studies and comprehensive application ofvarious relevant techniques on the basis of dynamic and static data analysis, using methods ofnumerical simulation. All the above will be elaborated to be of significance as following,1,enhancing the achievement on fine geological study by establishing three dimensionalgeological model on the basis of microfacies divided by sedimentary unit;2, accuratelypredicting the distribution of remaining oil with the aid of numerical simulation techniquesand dynamic and static data of oil deposit, realizing the quantization of oil remainingprediction;3,confirming the location of super high water cut and concentrated remaining oil,degree of injection-production, Abnormal pressure horizon and well point according to whichexploitation measurements can be optimized and strategies adjusted;4, evaluating differentsets of measurements with the assistance of numerical simulation, aiming at controls of twoaspects—progressive decrease of productivity and water cut increase, two indicatorsanticipating remarkable improvement. A comprehensive management on the basis of theresearch of the above and the down-to-earth measurements implemented in the field yieldsfavorable results that water cut increase rate reduces2.86percentage while progressivedecrease rate of productivity retards by4.38percentage.
