Low Permeability Oil Reservoir Development In Lin 56-4 Block Of The Dalujia Lin Ten Unit

In the Dalujia Lin Ten Unit fault block the central uplift of tectonic model big house, LinYi large faults in northeast area, oily drop km2, geological reserves 282 2.25 104t x. This unit in August 1973 oil production, developing, ZhuanZhu November 1977 start L46 well, try note. Current production speed is low (0.17%), low (5.6%), according to geological forecast the calculation method of comprehensive evaluation of low recovery (7.5%), compared the oilfield development level, the types of reservoir geologic reserves, the average recovery 22.9% comprehensive water 82.13% in 10 pieces, still in the development stage, low speed development potential. Therefore, based on the development status to enhance the recovery of fault block should be the first to its structure, fault fault block based on the combination logging data, and after adjustment layer data, small data etc, sand layer under the two top structure diagram, the sand layer top structure diagram, fault block area micro structural chart. Take the following measures to develop (1) plane perfect injection-production patterns, increase ZhuanZhu shots, increase water flooding, improve water oil reserves than single control, reduce the number of reserves. (2) lower reservoirs, acidification fracturing implementation measures yield note as. (3) based on the water pressure and improve performance. But should pay special attention to the faults of Wells, should strengthen the nets (systems) and the optimization of injection-production pressure system, and advanced technology of injection-production application. This paper mainly to solve the following questions: (1) find near 10 fault blocks and close to LinYi large faults, local structural development discrepancy phenomenon; (2) demonstrates the development plan in 10 units is feasible. (3) according to the development status of the unit worked out, and the treatment plan to evaluate the optimization scheme. (4) put forward plan implementation process problems should be paid attention to, to ensure implementation effect.
