Research Of Reservoir Evaluation And Stimulation Technology On Fu-yang Zone Near Xing69Well Field

The fu-yang zone of xingbei-development area Daqing oilfield is one of the mostimportant replacement zones, the zone oiliness area is92square kiloimetres that ispreliminary initially explored, estimated geologic reserve is1700×104t,in2003s, pilottracey si swamped in Xing69well field, utilize xing4-5line row polymer flooding8deepening experiment wells. By means of3D seismics, the reservoir bed is predicted,structural description, there is a preliminary recognition about fuyu zone. Thereforexperience is referred Daqing outer-ring oilfield, but it is affected by well networkdistribution limitation, development manner, well depth, well temperature, nowavailable technology is adapted to. For economical and effective development fuyuzone, Study on the fu-yang zone lifting process technology is necessary。Five sensibility experiments are developed, perforation protective liquid, lowdamage fracturing fluid is optimized, field process about zone protection is explored,formation sensitivity is figured out, hunting for main factors affecting formation flowpotential, it is done about enterence liquids examination and optimized which iseased, paraffin control process technology is done,landing string is optimized accordingto well structure, accommodation fuyang zone recovery is satisfied, extending pumpinspection cycle, production effect is come to project design requirement。...
