Wire-line core barrel is a drilling tool that retrives core from the drill pipe without lifting the drill. The complete set of drill tools includes: drill assembly, fishing tool, drill pipe, winch, picker, gripper and free clamp. It has the advantages of high drilling efficiency, high core taking rate, long bit life and low labor intensity. As the drilling deepens, the advantage becomes more obvious.

The power shortage will upgrade the East China Power Grid to a peak of more than 10 million kilowatts this summer.
"This year's situation may have not occurred in the past few years." Yesterday (April 19), Hangzhou Zhongce Rubber (34420, 210.00, 0.61%) Ltd. Director Ni Guoliang talked about the current situation of electricity consumption When told the "Daily Economic News" reporter. In 2011, some provinces and cities in East China and Central China experienced a tight supply of electricity. The peak of electricity consumption to be entered soon may also be the most serious since the power shortage in 2004. In the provinces of East China or the purchase of electricity, Xia East China Power Grid Corporation pointed out on the 13th "East China Power Grid 2011 Summit Summer and Safety Production Work Conference" that it is expected that the production tasks of the East China Power Grid will be very heavy this summer. Production pressure is unprecedented. It is predicted that during the peak summer season in 2011, East China's entire network is expected to have a maximum demand for electricity of approximately 190 million kilowatts, an increase of 14.9%. During the peak period, the power gap of the entire network in East China will reach 11.66 million kilowatts. The balance of power generation and electricity is severe, and the contradiction between supply and demand is prominent. According to Jiangxi Electric Power Company, since the beginning of this year, Jiangxi's electricity load has increased in the forefront of the country. As of April 12, Jiangxi's power consumption reached 20.12 billion kWh, a year-on-year increase of 31.09%. Due to the high power load, the supply of coal has continued to be tight. Since March 29, there has been a gap in the power supply of Jiangxi Power Grid. At present, Jiangxi Province has begun to work on outsourcing electricity to fill the gap in electricity consumption, and at the same time strengthen coordination with coal-producing provinces to ensure the supply and quality of coal. In order to alleviate the problem of electricity consumption in Zhejiang, Zhejiang Electric Power Company is also buying electricity everywhere. At the same time, East China Power Grid has also supported Zhejiang through electricity trading since March. According to East China Power Grid, since March, Huadong Company has supported Zhejiang's electricity consumption by nearly 1.7 billion kWh through electricity trading, including medium and long-term trading power of 1.1 million kilowatts and short-term maximum trading power of 3.1 million kilowatts. In addition, on March 25th, the East China Power Grid Power Trading Platform successfully organized monthly inter-provincial centralized transactions, reaching a total of 300 million kWh in April. According to CCTV, in the first quarter of this year, the electricity consumption in Jiangsu increased by about 15%. Recently, Wang Yonggan, a full-time consultant of the China Electricity Council, also pointed out in an interview with the media: "The power shortage may be the most serious one since 2004. During the 12th Five-Year Plan period, Jiangsu may have a power shortage of 15 million kilowatts. According to documents released by the Changzhou Economic and Information Commission, the State Grid Jiangsu Province company predicted at the beginning of this year that the maximum power gap in Jiangsu Province at the beginning of the year was about 7.3 million kilowatts, and the maximum power gap in summer will be around 10.7 million kilowatts. In fact, from the beginning of the year, power supply in some provinces and cities in East China and Central China continued to be tight. To alleviate this tension, the State Grid Corporation has increased cross-regional inter-provincial power trading efforts to fully support areas with tight power supply in Jiangsu, Zhejiang, Hunan, and Hubei. "Compared with previous years, this year's electricity cost and electricity consumption gap are relatively large. In the past few years, such a severe situation has not been encountered." As a power supplier, Ni Guoliang said that Zhongce Rubber has already prepared for this. . "Because our company's electricity needs are better, the local government is more supportive, so our current situation is still decent, but some companies must have problems with electricity." A variety of factors caused the off-season "electricity shortage" In the view of Ren Haoning, a researcher in the energy industry of China Investment Consulting, the appearance of the electricity shortage in the first quarter of 2011 was caused by a combination of factors such as tight coal supply and increased power load. In an interview with the "Daily Economic News", Ren Haoning said: "In the first quarter, the coal supply was tight and the price continued to rise, causing serious losses in the thermal power plant and insufficient work. The contradiction between 'market coal' and 'planned electricity' is increasingly prominent, and coal prices Rising, the cost of power generation has risen, but the price of electricity entering the grid has remained unchanged, causing the enthusiasm of power companies to decline, causing supply shortages.†Ren Haoning believes that since this year, precipitation in many parts of the country has been less, and the amount of water has decreased, resulting in a significant drop in hydropower. With the use of voltage. Ren Haoning also said that the phenomenon of “electricity shortage†is also related to the rapid development of local economy. “The rapid development of the economy has caused a continuous increase in the power load, especially in the second half of last year, enterprises that stopped production due to energy conservation and emission reduction resume production this year. The power consumption has increased sharply, exceeding expectations. The contradiction between supply tension and increased demand has directly led to a significant increase in the power gap. Ren Haoning also said that various accidental factors have also increased the tension in electricity use. “This year, coal prices have risen and coal quality has fallen. Many power plant generator sets have been shut down due to failures and overhauls. The proportion of unplanned outages has risen sharply. In addition, the overhaul of the Daqin line has intensified the tight supply of coal, and from Anhui to Zhejiang. The shutdown of the transmission line of '皖电东é€' has also aggravated the contradiction of electricity consumption in Zhejiang.†In Ren Haoning’s view, if there is a power shortage, it will bring many important effects: “The first is a serious impact on industrial production. This has led to a large number of enterprises being forced to adopt power-limiting measures, which restrict production development and enterprise growth, and is not conducive to economic development. Second, it has a serious impact on economic activities and affects regional competitiveness. Third, it includes enterprises limiting production and opening limits. Electricity and other measures will affect residents' lives; Fourth, power shortages will also have an adverse impact on the regional investment environment.†Referring to the measures to be dealt with, Ren Haoning said that the orderly power supply plan should be strictly implemented to implement peak-avoidance and peak-peak electricity measures. In particular, it restricts the use of electricity by power-consuming enterprises with high energy consumption and low output. "In the long run, local governments should vigorously promote energy conservation and emission reduction, promote economic restructuring, and limit the development of high-energy and low-output industries. At the same time, deepen power reform, promote the marketization of electricity prices and coal-electricity linkage reform, And vigorously developing new energy and clean energy, optimizing energy structure, and reducing the proportion of thermal power will also be an important direction for future efforts."
