关 键 词：Low permeability Horizontal well Recovery rate Complex well pattern
摘 要：Experimental research on the joint development of horizontal and vertical wells is carried out in this *** well patterns（VIVP,HIVP,VIHP and HIHP）were used to compare the advantages and disadvantages of water-injection and oil-production in horizontal and vertical *** is concluded that HIHP well pattern can form linear drive,delay injection water breakthrough time,improve sweep efficiency and reservoir recovery rate;horizontal wells are more suitable as production wells.
