(Reporter Ye Guihua correspondent Chen Jian) ​​Recently, Egypt's petroleum equipment global procurement agent Smith rushed to Hailing District, specially inspected the PDC drill bit produced by Taizhou Baorui Petroleum Equipment Manufacturing Co., Ltd., and purchased two on the spot. The box was checked back to Egypt.
The reporter saw that after packing two PDC bits, the volume was only one meter square, and the price was as high as more than 50,000 US dollars. "This is the value of the core technology." Zhou Yuhua, chairman of the company, revealed that the two parties have reached an agency agreement, Bao Rui will enter the Egyptian petroleum equipment procurement chain.
The abbreviation of PDC oil drill bit and polycrystalline diamond cutting bit is a major achievement of American oil drilling technology in the 1980s. Due to its high drilling speed and long life, it has brought epoch-making progress to drilling technology. China has introduced PDC bits since the 1990s, but the core technology has been blocked by foreign countries. “The drill bit is not enough, the oil and gas are not taken.†In oil and gas exploration, if the quality of the drill bit does not meet the requirements, the rock formation cannot be drilled, and the underground oil and gas cannot be extracted.†Zhou Yuhua said that due to the complex underground geological conditions, the rock formation is not strong. First, the drill bit has always been a consumable item. The annual consumption of the PDC bit in China exceeds 10 billion yuan, mainly relying on foreign imports.
Baorui Company, which was completed and put into production in 2004, mainly produces supporting equipment for oilfield development. At the beginning of last year, under the leadership of the Industry and Research Institute of the Municipal Science and Technology Bureau, the company successfully merged with the Southwest Petroleum University, a well-known university in China's petroleum industry, to form a school-enterprise alliance.
According to the agreement, the two sides established the "Taizhou Baorui Southwest Petroleum University Petroleum Engineering Technology Research Center", and new oil drilling equipment such as PDC bits became the technical research direction.
Through mechanical analysis and material improvement, Baorui gradually mastered the core data of PDC bit production and produced the first batch of PDC bits. After the trials of the three major oil giants of CNPC, CNOOC and Sinopec, the company's PDC drills have won unanimous praise, and the technical level is leading domestically, which can completely replace imported products.
According to the test, the drill speed of the drill is 3 to 4 times that of the first generation of cone bit, the rock breaking efficiency is high, and the bit loss is small. For example, in the past 3,100 meters deep oil and gas wells, drilling time required 22 days, loss of drill bit 4, and the use of the new PDC bit, drilling the same formation, the time is shortened to 11.5 days, the bit loss is only 2.
In order to speed up the drilling speed more quickly, Baorui has jointly established a downhole data analysis software and a drill bit database with Southwest Petroleum University since the second half of last year. "These softwares can analyze data of different geological conditions and rock formations, realize the individualized design of drill bits, develop PDC drill bits of different models and different cutting structures, and maximize the drilling and mining speed." Zhou Yuhua said.
On March 12 this year, the Sulige gas field in Inner Mongolia cooperated with Baorui Company to drill a gas well with a depth of 3062 meters. Through software analysis, the gas well rock layer is thick and difficult to drill. Baorui Company used PDC drill bit optimization and segmented drilling to design two 8.5-inch PDC drill bits. The result was that the drilling was successful for more than ten days, and the highest daily footage reached 1150 meters, creating a domestic daily drilling scale. The new record of speed.
At the beginning of this year, Baorui Company reached an agreement with the Lancaster Oilfield in Kazakhstan to drill two oil wells, G71X and G74X, with depths of 3,800 and 4,700 meters respectively. These two well sections are the most complex and difficult to mine sections of the field, with a depth of 4,700 meters that will create the highest depth of exploitation for Baorui's PDC bits. At present, Baorui has completed the cutting structure design of the PDC bit by analyzing the compressive strength and internal friction angle of the rock in the section, and the finished bit will be shipped to Kazakhstan in recent days.
At present, Baorui PDC bit has passed the API certification of the American Petroleum Institute, which is the highest certification standard in the global petroleum industry. Last year, the company completed sales of more than 40 million yuan, and sales will exceed the goal of 100 million yuan in the next three years.
