摘    要:总结了塔河油田碳酸盐岩洞缝型油藏的堵水工作.对堵水效果及其影响因素进行了探讨.认为堵水井储集体剖面类型、水淹特征及其类型、完井方式、投产方式对堵水效果有不同程度的影响:①大型洞穴型储集体堵水效果较其余储集体类型差.单一储集体剖面类型堵水效果较多重储集体剖面类型差:②底部出水型堵水效果明显好于其它出水类型.全井出水型堵水效果最差:⑨裸眼(直接)投产井堵水效果好于酸压(完井)投产井.最后就塔河油田超深碳酸盐岩洞缝型油藏的特点对行标SY/T5874—93的某些内容在操作上进行了讨论:建议统一机械堵水、化学堵水和复合堵水的有效期级别评价指标.并考虑降水幅度;措施有效率评价时应包含经济效益评价指标.针对油藏特点适当上提降水指标下限值;堵水增油量或有效期的计算应考虑堵前指标的动态变化趋势来综合确定。

关 键 词:碳酸盐岩缝洞型油藏  堵水效果  评价方法  行标

Abstract:After water plugging effects in Tahe carbonate fracture and vug reservoir were summarized and water plugging effect and influence factors were analyzed, we suggest that reservoir types of water plugging effects, watered-out features and types, completion ways and production ways influenced differently on water plugging effects: water plugging effects of cave-type reservoir is worse than the ones of the other type reservoirs, water plugging effects of single-type reservoir is also worse than the ones of multiple-type reservoirs; water plugging effects of well bottom water cut is better than the ones of other water cut types, it is worst for water plugging effects of all well log water cut; water plugging effects of bore hole (directly )production well is also better than the ones of acied treatment well. Some contents of SY /T 5874-93 standard in petroleum industry in term of Tahe reservoir are discussed, suggesting that estimate indicator of different levels in effective period include chemical plugging, mechanical plugging and composite plugging which should be united , the multitude of decreased water cut should be taken into account; the effective ratio of different measures should include economic target, lower bound of precipitation index should be raised according to reservoir features; performance trend of index before water plugging should be further studied during calculation for the increased amount due to water plugging or effective period.
Keywords:Tahe Oil Field  fracture and vug carbonate reservoir  water plugging effect  estimation method  standard
