在实际生产和管理中,热洗清蜡是油井正常生产的一项基础工作。如果热洗周期不合理,会使热洗达不到良好的效果。如果热洗周期过短,不仅造成热介质、燃料等的耗费,而且影响产量;热洗周期过长,则将使井筒中的蜡得不到及时的清除,影响泵的正常工作,严重时会出现井卡、抽油杆断脱等事故。同时,对于地层压力过低的油井,洗井液进入油层,产生倒灌现象,使产量恢复期较大。因此,在实际生产和管理中,制定出最佳、最合理的洗井周期,对于延长油井检泵周期保持稳定生产并取得良好的经济效益具有重大意义。
In actual production and management, hot wax cleaning is a normal production of oil wells a basic work. If the hot wash cycle is unreasonable, will make the hot wash does not achieve good results. If the hot wash cycle is too short, not only the heat medium, fuel and other costs, but also affect the yield; hot wash cycle is too long, it will make the wellbore wax can not be removed in time, affecting the normal pump work, will be severe Appear card wells, sucker rod break off and other accidents. In the meantime, for oil wells with too low formation pressure, well flushing fluid enters into the oil layer, resulting in intrusion, resulting in a large production recovery period. Therefore, in the actual production and management, to formulate the best and most reasonable washing-out cycle is of great significance for prolonging the stable production of the pump-checking pump cycle and obtaining good economic benefits.
