The Feasibility Study Of Waterlfood Development Of Block M Difficult-to-produce Reserves

The buried depth of Block M is generally in the460-620m, the viscosity of degassedcrude oil(50℃)is176.34MPa*s, belongs to ordinary heavy oil Production process is difficultdue to poor mobility. A series of measures such as pulse thermal flooding steam stimulation,steam flooding in situ combustion and so on has been carried out. But by the effect of the poorphysical properties, low reservoir temperature (38℃) formation energy of reservoir and otherreasons, they all can not change the status quo of fault block mining.This paper starting from drilling, logging, seismic, well logging, oil testing anddevelopment of test data, working out reservoir structure reservoir development waterdistribution law of M-block reservoir, and making complex operator of reservoir, study thereservoir properties and evaluate the affecting factors of injection. Aming at injectionfeasibility of the block making study, based on water injection to supply the formation energy,and further evaluate the complex operator of reserves. At the same time through researchingthe mining technologies and approaches which is suitable for this area, converting it to qualityreserves that can be to-produce Reserves. As.it. lay the material foundation for oil fieldproduction.
