摘要
随着葡萄花油层开发的不断深入,油田注采关系不协调的矛盾暴露出来。一是加密区存在注采不完善、油井水驱方向单一的特点。二是老井网下受断层遮挡、裂缝影响,井组存在有采无注、低效无效循环的弊端。为了完善注采关系,提高水驱控制程度,通过转注、补充井等方式对井网进行优化。调整后注采不协调井组水驱方向改变,水驱控制程度提高;同时井组产量保持稳定,递减幅度得到有效控制。
With the deepening of the development of Putaohua reservoir,the contradiction between the oilfield injection and production relationship is not coordinated.First,the existence of incomplete mining area is not perfect,the direction of a single water jet flooding characteristics.Second,the old well under the barrier by the fault,cracks,wells there is no injection,inefficient ineffective cycle of the drawbacks.In order to improve the relationship between injection and production,improve the degree of water drive control,through the transfer,fill wells and other ways to optimize the well pattern.After adjustment,the water diversion and water diversion control degree is improved,and the output of the well group is stable and the decreasing rate is effectively controlled.
