The Research Of Geological Reserves Distribution On The Data Of High Water In The Saertu Oilfield Of DaQing

Oil and gas reserves are their standing stock under the land, they are compositive reflects ofthe result of oil field and gas field exploratory development. Oil and gas reserves are the mostaim oil workers pursued and every important assignment during exploration stage ordevelopment stage.With more and more development stage works were penetrated at the date of highlycontaining water, computing geological reserves in 1980s and calculating untabulated reserves in1990s can not meet with the requests on the date of oil field. In order to solve the contradictionof reserves and recovers unbalance, computing geological reserves was asked to do deep intosedimentation unit and concrete type of sand body. For the sake of above, developing theresearch of fine computing geological reserves at the date of highly containing water, computinggeological reserves according to concrete type of sans body and beating out the character ofgeological reserves distribution, supply reliable base of reserves for infill develop, not only withgreat theory meaning but also with every important fact meaning.This text according to the deposit characteristic of Sa Zhong developed region in the DaQing oil-field, on the foundation of fine geology research, we made sedimentation micro faciesof interest area and certified 11 types sand body,they were made in different reason, research andmake the distribution characeters of every type sand body, at the last,we found out the changingrules of sand body under different well nets.This literary uses method of net of triangulation tocertain single-well-control area, overlaying to keep the area an all wells of the quantitycalculation, making the single well control area more reasonable, solving the error that" thethickness is even" calculate way of" single well control area= a total number of wells of a totalarea/ all wells of area" produce adopt currently, make the quantity calculation more reasonable.This text put forward the random boundary geology keeps the quantity calculation method,carrying out the random boundary, single well, well set, the different type sand body geologykeeps the quantity calculation, coming to a the geology to keep the fine and calculating requestof quantity. on the calculating foundation of quantity in the single well geology, connect therelation according to the well of water and oil well, the water well geological reserves keeps tomeasure the allotment influence factor, carrying on the water well geological reserves to allot,carrying out to use the geological reserves to analyse.We can reflect the distribution characters of geological reserves and residual geologicalreserves by the method of computing geological reserves bowed forward in this paper, supplyreliable base of developing oil field and increasing recovery ratio.
