【摘要】 现有的蒸汽吞吐油藏，油层动用程度很不均匀，只有４０％～６５％，而且吞吐井的蒸汽波及范围只有２５～５０ｍ，目前的１４１ｍ井网，难以提高油藏采收率，可通过加密井网的方式，达到提高油层动用程度及采收率的目的。更多还原

【Abstract】 The producing degree of present steam stimulation reservoirs is quite uneven. It only reaches 40%￣65%. Steam swept range of steam stimulated well is only 25￣50 m. With the existing 141 m well pattern, it is difficult to improve oil recovery factor. However, if adopting infill well pattern, the goal of improving producing degree and recovery factor will be achieved.更多还原
