HC Network Petrochemical News: “to stunt into the market, promote development through innovation” is the Dagang oil field logging company has been upheld by a great development with the new technology-driven path, the right to lead in this idea, the company actively involved in relevant research and staff technical upgrading and innovation, and new results are emerging.
DGK-1-based CNC production well logging system
The system logging process by the Institute of Dagang development of a new integrated computerized logging system, simple, compact and reasonable, the power allocation strong anti-interference ability, control, and with a pair of downhole Apparatus Power switch is simple and convenient and practical. Modular design of hardware devices, and defines the machine bus, various modules are inserted in the machine slot on the motherboard of the same run, the upgrade is simple and inexpensive to replace.
Equipment to Industrial Machine as the core, under the control of the computer’s real-time, downhole data through Cable Interface sent to the interface box, interface circuit of the corresponding box on the downhole equipment module sent to the signal denoising, separation, decoding, Plastic Processed into the computer, while computer controlled plotter records store data in real time, system application software interface with pull-down menus and multi-window graphical user interface and online help system with ready access to help support the application simple intuitive , the application software system robust and reliable, practical, to be completed by seven parameters, hole diameter, isotope, shed neutrons, electromagnetic flow, and other logging projects, can also be perforated according to customers need to configure the functionality (application-specific perforation ), and oil pipeline transportation of NC perforation perforation and many other work, as well as powerful software and hardware upgrades scalability. Compared with other similar instrument, the instrument hardware and software technology are at the advanced level.
Perforator diameter of 89 to improve 51 / 2 inch oil and gas well production casing new method
As oil exploration and development further, thin layer and the mining of sand more and more of the perforation of the increasingly high demand. To reduce the penetration depth in the low range, aperture index on the premise of hole density, to increase the discharge area, lower pressure, less sand, enhanced oil recovery, lower cost, oil and gas wells to achieve the best results the input-output , technology innovation has become a top priority. For now, the most used type of conventional perforator diameter of 89 domestic maximum hole density of 20 holes / m, had been unable to meet the oil production.
Port logging companies and technical personnel will be hole density greater than 26 holes / m, penetration depth greater than 400 mm, diameter not less than 8 mm, as a breakthrough innovation, research and development of a hole diameter of 89 higher density type perforator. The study has successfully passed the testing center in Daqing oil field perforating test, to resolve the thin and the sand in the perforation to find a new way.
Diameter of 32 mm high pressure and temperature combination of gamma magnetic positioning apparatus
Diameter of 32 mm high pressure and temperature combination of gamma magnetic positioning instrument is for the super-deep well, window wells and construction needs of small drill wells specifically developed. The instrument used in a casing part of the special steel high pressure Make , Temperature 175 , pressure indicator up to 150 MPa, in the 7,000 meters to ensure the instrument can be used around the wells. In circuit design, signal processing and signal amplification coupling part collection of high-thick blocks into the circuit, the instrument signal to sequential processing safe components removed in the past caused by the Weld, and insulated low potential causes of accidents. Instrument has in Xinjiang Shanan 1 Well (depth 6000 m), tower 54 wells (depth 5400 m) used in construction, are a successful, 100% pass rate data.
Through practical application of this instrument fully with the diameter of 38 mm and 50 mm in diameter combination of instruments comparable to the gamma magnetic orientation, more than 80 counts per second, apparatus fluctuation error is less than 10%.
Present, three new technologies and new methods have been successfully used in market practice with remarkable results. I want to comment
