摘要
随着渤海油田勘探程度逐年深入,其勘探领域也逐渐拓宽,深层潜山油气藏、高温高压油气藏、含硫油气藏等复杂油气藏都相继发现。由于深井井身结构复杂,常规测试管柱难以满足该类复杂井的测试作业。在高安全要求的前提下,针对渤中区块深层潜山气层裸眼测试管柱进行优化,通过RD旁通试压阀和RDTST阀的配合使用,解决了该区深层潜山裸眼测试难题,形成了一种新的深层潜山裸眼测试管柱技术。
With further exploration at Bohai Oilfield year by year,the exploration is going to more areas. More complex hydrocarbon reservoirs are discovered,such as deep buried hill reservoirs,HTHP reservoirs,sulfur-containing oil and gas reservoirs,and condensate reservoirs,etc. Because of the complicated well structures,conventional test string is hard to adapt to such kind of complex well testing operations. To meet the higher security requirements,optimization is made on the test string for buried hill reservoirs at Bozhong block,RD bypass valve is combined with RD TST valve to overcome the openhole test challenges there,establishing a new openhole test string for deep buried hill formations.
