Research On Well Pattern Adjustment And Optimization Of Jing 63-35 Block Layer

J63-35 fault block is situated in the northeast side of the edge of the Shen 84-an12 fault block, with 6 single sand body as unit. Because of restriction by the sedimentary facies, sand body distribution, porosity and permeability distribution, micro structure characteristic, oil distribution and affecting factors in the current development mode is not perfect conditions, there are many have taken no note, no well controlled area, effective response is weak, the problem of poor reservoir producing degree.Through the analysis of the characteristic of continuous reservoir, reserve scale, sand block single sand body of mineralization of static 63-35 and so on, and combined with logging data, well logging data, seismic data and other research results and the formation of static dynamic production data of the study area the edge block list sand body optimization, numerical simulation, analysis and calculation of reserves of oil and water distribution of remaining oil enrichment area, clear. Aiming at the bad adaptability of well pattern, injection production well ratio is relatively low, the well spacing density is low, the well spacing larger area by using horizontal well technology in well network encryption, improve development well network, so as to realize the efficient development of the overall requirements.
