Turpan Hami downhole production problems aimed at tackling 81 QC results, effective 10 million yuan
Chinese oil network news August 12th, Flaming Mountains fracturing construction site, past fracturing hammer union employees perspiration comes down like raindrops scene disappeared, replaced by "air hammer" in the job, you can easily complete the work.
In the past 3 years, Tuha oilfield downhole company has extensively carried out QC activities to solve the problems of production, quality and safety. Each unit has registered 95 QC teams, and has studied 81 outstanding achievements, creates the benefit 10 million yuan.
The QC campaign focuses on improving efficiency. Every year, Turpan Hami underground fracturing in 280 wells, the average fracture union 16 butt, each of the Union and 5 minutes, sometimes hammer not easily hurt. The QC development team of the equipment maintenance center developed the hammer "air hammer", which was completed in 1 minutes. It not only improved the work efficiency, but also eliminated the risk of wounding.
QC activities focus on improving the quality of tools. Elevator pin Turpan Hami underground company currently in use, the wire ring welded on the pin shaft, the wire diameter is small, easy to weld cracking in use, each elevator pin used for the duration of 4 months. Study on the repair process of QC well group to develop the new elevator pin, this product is originated in China, has the advantages of simple structure, high durability, low cost, total production of 108 elevator pin, no quality problems.
In addition, according to a variety of fracturing design formula, dozens of fracturing fluid and the preparation of the experimental database of fracturing and acidizing by QC research group, has the guiding sense to the construction site, the fracturing success rate increased from 92% to the current 95.7%. The test team QC team used high precision micro pressure gauge, can cut stage fast measurement of oil-water mixture in the form of a variety of output rate, used in oil production, the measurement error is controlled within 3mm, for the rapid production of providing conditions.
