One-well multi-control method for offshore low-permeability reservoir thick oil layer exploitation

InactiveCN104818978ALow costReduce well construction costsFluid removalPrincipal stressDisplacement pressure
The invention relates to a one-well multi-control method for an offshore low-permeability reservoir single relatively thick oil layer. The method at least uses a long section horizontal well and a plurality of artificial fractures located between an oil layer top and an oil layer bottom, wherein the extension direction of a well section of the horizontal well is the maximum principal stress direction of a stratum; the artificial fracture surfaces are vertical to the horizontal well section and extend along the minor principal stress direction; injection and recovery are carried out simultaneously by implementing an offshore same-well injection and recovery technology in the horizontal well; injection water is firstly injected into the artificial fracture at the farthest end from the root of the horizontal well section; the injection water drives crude oil to enter the closest artificial fracture to enter a wellbore so as to be recovered; and when the far end artificial fractures are flooded by water in succession and water plugging is invalid, conversion is carried out in sequence from a far end to a close end. According to the method, the well building cost is reduced; the injection effect is improved; the distance between adjacent artificial fractures is adjusted, so that the small-well-distance water injection is realized, the displacement pressure gradient is favorably built, the start pressure difference is overcome, and the oil recovery effect is increased.
