North Da'an Oil Field Oil Deposit Project Plan Design And Optimal

North Da'an the oil field is located within the boundaries of the Jilin Province Da'an city. East this area the neighbour Nenjiang River, south and the Da'an oil field is connected, the north west is the red hillock oil field. The areal structure position is located south the pine distant basin the central occupied region Da'an red hillock step middle, west west the neighbour the pitch area, east is hollow for the ancient dragon.This local development main force oil layer holds -odd oil layer for the spring four sections, the spring four sections of tops overall structures appearance the syncline structure which leans for the north, in the north and south to the fault zone between, north west - Nandong to the reservoir granulated substance body which mops the fault is cut and seals off the function, forms the complex fault block oil deposit, east of the fault zone, reservoir oiliness the lithological character, the natural control, has been mainly formed the wide range fault - lithologic deposit and the lithologic deposit.Da'an red hillock step at present accumulates submits 149.3 million tons to verify the petroleum geology reserves, use proven reserves 27.43 million tons, 2004-2005 year in this area new realization proven reserves 50.48 million tons, in order to cause the proven reserves to use as soon as possible, from 2004 in red 75, is red 75-2, the big 26 south sub-areas opened the production pilot area, has laid the foundation for this local effective development.In the deepened oil deposit geology research and in the optimized necessary technology foundation, to developed the design the foundation condition, the petroleum geology characteristic, the oil field geological reserve, the oil deposit geology modelling, the pilot area development effect has carried on the thorough analysis, the oil field oil deposit project has carried on the overall deployment to Da'an north. Simultaneously carried out the development formation design, the development way design, the well pattern system design, the note has picked the system design and the individual well productivity design and so on, and has carried on the forecast to the oil field plan design development target.North Da'the oil field oil deposit project plan according to the well drilling way and the well position network deployed that altogether designs three sets of plans, through delivers the investment to analyze and to invest the increase benefit contrast, has determined north Da'the oil field oil deposit engineering design plan.North Da'an the oil field overall development plan research work area area 253 square kilometers, have verified the petroleum geology reserves 15.68 million tons, treats proven reserves 50.48 million tons which approves, equals 122 square kilometers to contain oil the area, 66.16 million tons reserves (including upside level and so on grape flower, high platform replace reserves). The main goal level for holds -odd oil layer, next for the grape flower oil layer and the catwalk sub- oil layer, the partial distribution has the black emperor temple oil layer. From northwest mops to the southeast the reservoir is cut by the north and south to the fault for the fault - lithologic deposit and the lithologic deposit. Holds -odd oil layer to divide into four granulated substance groups 12 subzones, the average effective thickness 8.7 meters, the single-layer effective thickness is smaller than 1 meter, average porosity 11.97%, penetration coefficient 0.63×10-3μm2, underground crude oil viscosity 1.76 mpa.s, about oil layer burial depth 2,200 meters, formation pressure 20.5 Mpa, saturation pressure 11.1 Mpa . The grape flower oil layer nature compared to holds -odd oil layer well, the penetration coefficient 4.3×10-3μm2, the single -layer effective thickness is bigger, may amount to 1 - 3 meters.The oil field overall development plan design use contains oil the area 122.1 square kilometers, the use petroleum geology reserves 52.02 million tons, has divided 24 developments sub-areas. Holds -odd oil layer to adopt set of formations developments, the main body partially uses 150×500 the rice diamond counter- nine dispersed water injection well pattern, deployed development well 1,594, enter ruler 364 myriameter. After follows "the whole plan, divides a step of implementation, fat is first thin, the attenion benefit" the policy, divides 5 years accumulation to complete produces can 1.25 million tons, the single well daily production 3.5 tons, the extraction speed 2.5%, 2013 annual output amount to the peak value 1.08 million tons, the corresponding extraction speed 2%.This project was the oil field whole development plan, also has the investment content which already occurred, including ahead of time explored and the small scale development experiment, in carried on the exploration to this area to know and to develop in the foundation which the experiment knew, the development project overall feasibility study proof, advanced together the behavior time 5 years development design. The characteristic is the project is huge, involves the oil field exploration development many systems specialty, simultaneously carries on the multi- plans compared to elect, to carry on the whole to optimize, carries on the project cost estimating to the entire project, method and so on utilization economic analysis, carries on the proof to the project feasibility.
