Zhu Hongren, chief engineer of the Ministry of Industry and Information Technology, who is mainly engaged in the work of small and medium-sized enterprises, has just returned to Beijing from Wenzhou, Zhejiang Province. He will hold a meeting of the State Council to promote the development of small and medium-sized enterprises in the first day of June, the National Development and Reform Commission and the Ministry of Finance. The relevant responsible persons of the ministries and commissions participated. According to informed sources, the heads of the ministries and commissions at the meeting realized the actual difficulties faced by SMEs, especially under the continuous pressure of tight monetary policy and inflation expectations. The production costs of enterprises have risen sharply, and operational pressures have increased. SMEs with money are now more difficult to finance. "Reducing the tax burden has already formed a consensus within a large scope, and put forward opinions and suggestions for further doing a good job of reducing the burden of enterprises. It may involve more than 100 administrative fees for canceling and stopping the collection," said a Ministry of Industry and Information Technology official. More and more ministries are joining the ranks of tax cuts and burden reductions. The Ministry of Finance recently issued a notice requesting that the import tariffs on gasoline, diesel, aviation kerosene and fuel oil be significantly reduced from July 1, 2011, and diesel and aviation kerosene will be imported at zero tariff. Prior to this, the National Development and Reform Commission also said that it will reduce coal import value-added tax and port-related expenses. The NDRC's tax reduction involves a total of 33 tax items, mainly energy and raw materials, and is a major tax reduction measure in recent years. Lin Boqiang, director of the China Energy Economic Research Center of Xiamen University, said in an interview with this reporter that imported coal accounts for only 2% of the country's coal consumption, and diesel accounts for less than 1.3%, which will not have much impact on prices. Rather than saying that this is to alleviate imported inflation, it is better to encourage enterprises to import more and guarantee supply, so as to avoid “electricity shortageâ€, “oil shortage†and “coal shortage†in July and August. Luxury tariffs are also brewing down. The Ministry of Commerce has recently released news from the outside world. It intends to start with tariffs and appropriately reduce the relevant tax rate for luxury goods, in order to prevent the loss of domestic strong purchasing power from abroad and to re-expropriate purchasing power back to China. Previously, Xu Shanda, deputy director of the former State Administration of Taxation, also said that business tax is a very serious institutional obstacle to restrict the development of the service industry. To develop the service industry and start domestic demand, it is necessary to reform the business tax. Zhu Baoliang, chief economist of the Economic Forecasting Department of the National Information Center, believes that reducing import taxes and reducing corporate tax burdens are all part of a proactive fiscal policy. In his view, the next fiscal policy will be more active, and relevant departments will also introduce measures to expand domestic demand and maintain growth. "Whether it is to reduce import taxes or reduce corporate tax burdens, it is a means and measure to expand domestic demand, especially consumer demand, and at the same time, it can alleviate the difficulties faced by enterprises. It can be described as one stone." Zhang Hanya, president of China Investment Association, told this reporter. Say. The experts interviewed agreed that the ministry began to intensively reduce taxes and reduce burdens, indicating that fiscal policy is more active. The more active fiscal policy is due to the decision-making level's concerns about China's economic downturn. According to data released by the National Bureau of Statistics, the value-added of industrial enterprises above designated size increased by 16.5% in May, but it fell by 1.3 percentage points in April. Zhang Hanya said that the enterprises above designated size this year are different from last year. This year, sales were over 20 million yuan, compared with more than 5 million yuan last year. This will inevitably cause statistical distortion, and the actual added value may be less than 10%. Zhang Hanya is not optimistic about the economic trend in the second half of the year. "The data in June is likely to be lower than that in May. It may be lower in July, August and September, and then decline. The data in the third quarter is definitely not good." China Logistics and Purchasing Union The China Manufacturing Purchasing Managers' Index (PMI), which was released in June, was 50.9%, down 1.1 percentage points from the previous month. The index continues to remain above 50%, reflecting that the current economy continues to grow, but the growth rate is still continuing. The Ministry of Industry and Information Technology's research is also not optimistic. The newspaper was informed that the most serious areas for SMEs to shut down are Wenzhou and the Pearl River Delta. 20% of enterprises in Wenzhou have stopped production and stopped production. The enterprises in the Pearl River Delta have stopped production, exceeding 30%. There are indications that the problems and contradictions of financing difficulties for SMEs are becoming the main contradiction in economic life, and tight monetary policy is being increasingly severely tortured. The famous financial commentator Shuipi believes that the central bank’s practice of raising deposit guarantees has also approached the dead end of the policy, and the effect has gradually lost and the negative effect has become increasingly obvious. Under the premise of continuous expansion of government investment, the only ones who are tight monetary policy can only be SMEs. They are undoubtedly victims of the crowding out effect. Many experts interviewed by the China Times reporter said that it is somewhat evasive to implement only a proactive fiscal policy. At present, the tight monetary policy is the chief culprit in pushing small and medium-sized enterprises to a dead end. Monetary policy should return to a stable or even moderately loose And the adjusted window should not exceed the fourth quarter of this year at the latest.
 Drilling BOP And Control System
During oil drilling, it is installed on the wellhead casing head to control high-pressure oil, gas, and water blowout devices. When the oil and gas pressure in the well is high, the blowout preventer can close the wellhead (shut down). When the heavy mud is pressed into the drill pipe, there is a four-way under the ram, which can replace the mud invaded by gas, increase the pressure of the liquid column in the well, and suppress the ejection of high-pressure oil and gas.
Its types are divided into ordinary blowout preventer, universal blowout preventer and rotary blowout preventer. The universal blowout preventer can be activated in emergency situations to deal with any size of drilling tools and empty wells; the rotary blowout preventer can realize the blowout and drilling operation. In deep well drilling, in addition to two ordinary blowout preventers, universal blowout preventers and rotary blowout preventers are often added, so that three or four combinations are installed at the wellhead.
Annular Blow-out Preventer Annular Blow-out Preventer is usually equipped with a large gate with a ram-type blowout preventer. During operation, a sealed annular space is formed between the pipe string and the wellbore. When there is a pipe string in the well, it can also be separated The well is closed, but it will not work after several times of use, and long-term shut-in use is not allowed.
