Oil Plant Nine Engineering and Technology Brigade to extend the inspection pump, pipe column overhaul time trick to easily skip the "double 700" annual for the whole plant to save operating expenses more than 2300 million Daqing Reuters (Qu Fengbo Yu Guanghua reporter repair army) Oil Plant 9 Check the pump and column overhaul cycle, both skipping the height of 700 days. As a result, nine plants each year less pay more than 2300 million operating expenses. In the past, nine factory oil well pump cycle up to 398 days, wells can reach 480 days. Check the pump cycle is short, frequent operations, operations brigade busy "halo". However, you have to hire a job team. Check the pump or repair pipework time with two days, a single well cost more than 30,000 yuan. The number of operations, the cost of oil is difficult to drop, but also, due to pump inspection and maintenance of columns, the annual output of over 2,000 tons. As a result, scientists here to extend the inspection pump and column maintenance cycle launched a "charge." Sure enough, an item of scientific research has brought surprises to people. Let's talk about wells, to achieve a "triple jump." Their own research and development of washable well pipe supporting technology, from low pressure water injection to high pressure water injection, subdivision water injection has also achieved a seal can wash well. Six of these achievements won the Technology Innovation Award. As a result, the overhaul period of water-injection string jumped to new heights from an average of 480 days to 618 days. After 700 days, the longest single-well overhaul period reached 967 days. Look at the pump cycle to extend the unique skills, unique skills have 3 strokes. One is out of the "misunderstanding." In the past, copy the old oil field approach, that the greater the pressure wellhead the better, however, the effect is not satisfactory. After research, the conclusion is not the bigger the better, the key is to choose the best kowtow machine "kowtow" number. Because of the low permeability of peripheral oil fields, thin oil reservoirs, kowtow å’£ å’£ kowtow, ineffective to do more, the result, the pump tired. Out of the "misunderstanding", they developed a set of optimized pumping parameters of the software, through the calculation to determine the parameters, the effect is good. Second, anti-off wear technology has a new breakthrough. After the design of super rod limit, last year also developed directional well trajectory simulation technology, the installation of sucker rod centralizer more scientific. Deep well up to install 154 centralizer. The partial wear rate dropped from 14.6% five years ago to the current 7.9%. Third, anti-pump card on the new measures. Oil pump is most afraid of wax cards and sand card, a card would have to check the pump. In the past, some methods worked well, but their newly applied superconducting thermal wax removal technology was even better last year. The whole plant more than 4000 wells, wax cards appeared last year, only 13 wells. Sand control card, they focus on the application of sand screen technology, the effect is very good. Now, nine plants to achieve inspection pump and pipe overhaul cycle "double 700" in 2006 than the previous year, the number of operations was down 656 wells, according to a single wellhead operating expenses 35,000 yuan, the operating cost savings of only one year More than 2300 million.
