China Petroleum network news, as of November 13th, Turpan Hami oilfield large displacement large scale fracturing volume control technology has successfully applied 9 wells, single well average daily production of 33.4 tons, compared with the conventional volume fracturing production increased by 40%.
Tuha oilfield has established a national tight oil development demonstration zone in Ma 56 block by tackling key problems of horizontal well + volume fracturing technology. In order to further improve the recovery efficiency of tight oil wells in Ma Zhong oilfield, 44 infill wells have been deployed in Tuha oilfield.
On the basis of practical experience in volume fracturing, Turpan Hami Engineering Institute has put forward the concept of volume controlled fracturing for the first time, so as to effectively develop the tight oil and gas technology, and solve the problem of tight fracturing oil production and benefit. After nearly a year of technical research, Tuha oilfield formed a "pre water storage, dense dense cluster distance, improve some distance from the slippery water ratio, using quartz sand instead of ceramsite" large displacement large-scale joint control volume fracturing technology. Technical personnel to take "water + water + slippery low concentration of guar gum fracturing fluid combination, improve the slippery water proportion, using quartz sand instead of ceramsite, single fracturing cost is reduced by 45%, as the volcano rock, tight oil development reserve effective reservoir reconstruction technology.
