Research On The Fine Description Of The Reservoir In Lamadian NN1Block

The Lamadian oil field reservoir mainly has the thick oil level which deposits by therivers primarily, passes through the unceasing development practice, finally indicated thethick oil level is still the fine control key point in the super-high watercut stage,but the distribution characteristic of the structure contact surface is the important factoraffecting the distribution character of the remaining oil in the thick oil layer.In order to satisfy the demand on the work about the “four fineness” model area, deepen thetechnology of fine describing the reservoir, and extend the dissection technology of the promotionstructural unit, This text has carried out the fine dissection research in NN1Block area.First according tothe developping scale of the single sandstone and the origin characteristic of the internal structure contactsurface, using the basic principle of the hierarchy analysis, carries out the fine recognition research to thesingle sandstone, and further undergo the fine dissection of the interbedded construction structure of thethick oil level that the thickness is above to2.0m; Secondly establish the structure model and facecontrolling sandbodies model and the three-dimensional geology model of the interbedded structurecontact surface and interlayer using the union of the well and the seism, and describe the interlayer surfacedistributed characteristic using model slice; Finally using the fine digital-analog technology, to developvalue simulator study on the subdivide small sub-area in the area, and quantificat remaining oil distributedcharacteristic.Restructures the underground understanding system, realizes to the three-dimensional finetoken on the underground reservoir characteristic and quantification description on the remaining oil,achieved the improvement water drive stage development effect, enhances the recovery ratio the goal.Through developping the research on the oil deposit fine description engineering in NN1Block, thistext fine describes the reservoir growth characteristic, establishes the three-dimensional geological modelbased on the structural unit, fine tokens the structure characteristic and the reservoir distribution, lays thefoundation for the remaining oil description, instructs effectivly the fine water drive developmentadjustment, and has achieved the research goal.
