A Study On Points Sand Body Reserves Producing Status Of Satellite Oilfield Developed Block

Satellite oilfield in changyuan eastern of daqing, is one of low permeability reservoirs in the peripheral oil fields. Satellite oilfield grape spend reservoir overall growth is poorer, Oilfield is very scattered by fault segmentation, is difficulty developing. The currently used Injection-production spacing 250～350m Against nine points area well nets development, Obtaining certain capacity. However, due to the complexity of the development of the reservoir, Each small layer connected sent, Wells network in waterflood control degree is low, Producing extent is low. Therefore, in order to improve all kinds of oil producing extent, improve satellite oilfield recovery, we must analysis all kinds of reservoir use conditions, Looking for effective redevelopment method,for the foundation of Long-term development of Satellite oilfield.This paper analyzes and studies the distribution of remaining oil and Potential research of Satellite oilfield, according to the cause of remaining oil, studied the remaining table-manipulation method and the expected result of different Wells, different layers; For reasons of the formation of remaining oil, given the Table-manipulation method of different types of remaining oil,and evaluation the Measure effect, for the foundation of redevelopment further remaining oil and improve oilfield recovery.Further studied the use status of all kinds of reservoir, analysis the reserves producing degree of currently well nets conditions in Scale development blocks; Choose two typical development block establish numerical model, historical fitting, Residual oil research By using numerical simulation for typical block, quantitative analysis water conditions of reservoir, analysis and comparison developing index variations when take different treatment measures;This paper analysis and prediction development indexes of take different measures workload by Numerical simulation method, So that we can clearly understand the effect of different measures, the future development situation of oilfield, provides scientific basis for satellite oilfield development decision.
