Chinese oil network news in September 27th, with the deep tectonics of the Huoerguosi Huo 11 completion, the new historical drilling fluid Chuanqing again to write the "liberation of Huoerguosi oil and gas field".
Huo 11 well is the nineteenth well constructed in Huoerguosi. Igawa high density and strong sealing oil base drilling fluid power well Huo 101 only 6.9 days will be safe and rapid drilling through the "sea of death" said the Anjihaihe group, compared with the same structure of other wells, the horizon at least shorten the drilling cycle for more than 80 days, Party A is known as "the liberation of the Huoerguosi oil and gas field".

It is the deepest well in the well, and there is no drilling data for more than 1800 meters. In this regard, Chuanqing drilling established technology research group, formulate the construction scheme of customized drilling fluid, long-term suppression technology, near wellbore hardening technology, control technology and a new type of fractured oil based drilling fluid plugging technology were used in different strata, the Huo 11 become the block of the same openhole pressure system call the first well, created the oil based drilling fluid density of 2.52 grams per cubic centimeter, the highest single day and Huoerguosi block footage of 301 meters and a number of records.
