【Abstract】 The drilling program and technological measures of shielding temporary plugging technique for formation damage control have been widely used after success was made in SZ 36 - 1 and QHD 32 - 6 oil fields. According to well testing results, production index per meter of trial well increased 14.5% -37% and skin factor decreased greatly. Therefore,its application has very good economical benefits. This technique not only controls formation damage in such reservoir, but also controls hole enlargement and is benefit to one trip success ratio in well logging.更多还原
