Research and practice of underbalanced horizontal well drilling technology in deep buried-hill reservoirs in Nanpu Oilifeld
摘要
Abstract
The reservoir forming condition of buried-hill is complex in Nanpu Oilifeld, and the vertical and horizontal heterogeneity is very strong. In order to effectively raise fracture penetration rate and achieve economic development, underbalanced drilling technol-ogy for horizontal wells was researched and applied. For the following drilling risk situations, such as:deeply buried, high temperature, high gas-oil ratio, narrow density window, prone to lost circulation and well kick, etc, a series of studies are conducted,such as op-timizing a temperature resistant oil-in-water drilling lfuid system, analyzing the gas-oil ratio and the application of real-time pressure monitoring and reservoir evaluation technology, designing the underbalanced and managed pressure drilling parameters, monitoring dynamic and static temperature variation and the abnormal characteristics when drilling buried-hill fracture, a set of underbalanced drill-ing technology was developed for horizontal wells in deep buried-hill reservoirs with high temperature in Nanpu oilifeld. The results of application show that the technology is able to ensure safe drilling and economic development for buried-hill reservoirs in Nanpu Oilifeld, and also to give references for drilling the same type of reservoirs.关键词
