Research Of Water And Oil Distirbution Of The Complex Structure Lithology Reservoir In Gao20Oil Area

Now, the oil field already puts into the high containing water exploitation moment, thedistribution of residual oil is thin and complex, the change of the new area is from the bettergeology qualification reservoir to the poor, the water and oil distributing is from simple tocomplex。following the more study of the exploration and development, the quality of newincrease reserves is poor, the most lies in the bide of the oil field, the economic performance ispoor。The high20oil area lies in the north side of the GAOTAIZI oil field, it is exploded in2007byGULONGBEI, lies in the west of the DAQING oil field, the north of the GAOTAIZI oil area。Itsmain oil stratum is PI, it belongs to the narrow and small structure lithology reservoir, thecontaining oil area is28.58km2, petroleum geology reserves is1240.85×104t, the distributing ofwater and oil is complex, there is the phenomenon of water and oil coexistence in the samesedimentation formation, and the water stratum lies in the higher part, the oil stratum lies in thelower part. There is the phenomenon of water is up and oil is down in the portrait。 The precisionof the electricity and testing is low in the high20oil area, there is44.4%using the water and oiltesting data of the produce well. Because the low of the understand for geology character, thereare89wells not to drilled in the development, the part geology reserves is difficult to develop。To understand fully the rule of the sediment in the deposited formation and the distributingcharacteristic of water and oil, this article anvances to use the technology of combining test withearthquake, passing detailed explanation of structuring with three structure set up the moldpractical tiny structure and inside small break the layer；full use of reflect drilling, perspective andproperty slice up, to enhanced the forecast cell precision of the narrow and small structurelithology reservoir； to establish the estimation plate of water and oil formation, and the secondexplaination to the oil and water formation of the study area, to explain oil and water formationcombining mobility water technique, to use structure, deposited formation to particularexplaination, to enhance the identify precision of water and oil formation； we can study the waterand oil characteristic by analysis structure and faultage and water and oil distributing relation. Theresearch production is meaning to identify oil and water formation of complex area in oil fieldside。...
