LIL 2D is a digital logging system specially designed for the convenience of field work, which can connect with various kinds of pipe and log. Using a series of advanced technology, the system improves the use of one ground-based instrument controlling one heavy logging probe into one ground-based instrument controlling various kinds of logging probe. It also includes the deep measurement, the power supply and so on. The instrument has a light weight and simple operation and maintenance, which can be connected to the tube type, which can be aseismatic, temperature-resistant, moistureproof and high reliability.
Description
LIL 2D integrated digital control logging system is a new generation of digital logging equipment. This set of equipment has the following advantages over other similar products:
The measurement parameters are large and the scope is wide.
The reliability is high and the Mean Time Between Failure (MTBF) is long.
Portable, convenient for mobile transportation.
Operating and maintenance is simple.
LIL 2D system can measure more than 20 kinds of parameters, covered with metal ore, coal, oil field, radioactive, hydrology, and other areas of the various user's requirements, with great cost-effective.
Advantages
Standardization and Modularity
In the LIL 2D integrated digital control logging system, both hardware and software, no matter probe or ground box, signal measurement or signal transmission, have adopted the standardization and modularization design concept. The benefits of standardization and modularity product is excellent in products' consistency , maintainability and reliability. It is convenient to operate and maintain. The accessories are 100 percent universal and can be expanded at any time.
Fully Underground Digital and Measurement's Signal Transmission
All the signals from the underground probe are converted by A/D and sent to the ground after being encoded. The underground probe is a two-way street communication. Digital code transmission measurements greatly improve the anti-jamming capability, and the system itself can correct the error code, which guarantees the quality of the signal transmission.
Oversampling Technology to Obtain the Most Formation Information
The LIL 2D system uses the sampling method for the collection of formation information. The oversampling amount increases with the decrease of the logging speed, and oversampling ensures the need for digital filtering, enhancing spatial resolution and screening useful information.
Small Size of the Underground Probe with High Pressure
The diameter of the LIL 2D probe is almost Φ40 and Φ50 mm, and the appearance length is 1000~1500mm. The probe is made of stainless steel. Resistance to 20~40 MPa water pressure, temperature of 70 ~ 90 ℃. Special orders can be 60 MPa water pressure resistance, temperature 120 ℃ resistance.
