Turpan Hami underground capture technical difficulties to raise production
China petroleum Turpan Hami underground network news companies around the needs of oil exploration and development, the main producing areas of technology based on solving the problem to solve the technical difficulties of oil, the main oil producing areas of focus, strengthen the scientific research and innovation, in the fields of fracturing and acidizing and downhole operation, etc. The coiled tubing to achieve breakthrough, effectively promote cost reduction. As of August 11th, the construction of various measures wells nearly 300 times, nearly 40 thousand tons of oil increase.
In order to solve the three cattle and horse Santanghu East volcano rock in tight oil general refracturing effect, mechanical fracturing difficult problem, Turpan Hami underground company based on extensive research and experiments on the development of horizontal well application test, ball staged repeated fracturing field, has been successfully applied in 10 wells. The average single well oil production of 12.6 tons. Aiming at lukqin in imperfect injection production pattern, water injection, injection problem owe to the lack of effective complement formation energy, the conventional fracturing effect is not ideal, carry out the "Turpan Hami underground storage water + fracturing experiment, successfully applied in 17 wells, the average daily oil well 6.7 tons, has now become lukqin in the main production measures. Actively promote the vertical well fracturing sandstone volume, reference volume fracturing transformation method, preferably "slippery water + low viscosity liquid, with large displacement and large amount of fluid to improve the productivity of single well, the average daily gain of 3.5 tons of oil.
