Exploration and Application of Fracturing Operations in Igneous Rock Reservoirs in Bohai Oilfield
In view of the current development and production of oil Wells in Bohai Sea,the demand for the development and exploitation of low permeability reservoir is increasing.Fracturing,as a recognized tool to increase the reservoir production of low permeability reservoir,has gradually stepped on the stage in Bohai oilfield.The reservoir of well A43 of an oilfield in Bohai Sea area was affected by igneous rocks,and the designed production was not reached after putting into operation.This paper introduces the background of fracturing operation of well A43 in this oilfield,the check of pipe column,the construction scheme,the situation of field operation and the effect after operation.At present,the oil increase effect after operation of this well is obvious and good.Fracturing technology has a broad application prospect in the development of low permeability reservoir in Bohai oilfield.
