Introduction Polymeric materials based on polylactide acquire their significant importance in a variety of human activities.
Such materials are biocompatible, do not cause any environmental pollution as in the process of biopolymer production, the CO2 emission into the atmosphere is 2-3 times lower [1, 2].
Large raw materials, material and energy resources are required to implement these steps.
At the same time, the recycling share of spent polymeric materials and products based on polylactide is very small.

Discussion on Preprocessing Technique of Geophysical Logging Data Huaping Yu1, a, Huan Wu2,b 1 College of Computer Science of Yangtze University, Jingzhou, China 2 College of Petroleum Engineering of China University Of Petroleum, Beijing ,China a yhpjz@126.com, b wjndxf@126.com Keywords: logging data; environment correction; normalization; interpolation; standard procedure Abstract: Logging data preprocessing is the basis of reservoir description and reservoir evaluation with logging data, which is a technique that can reduce the influence generated by the non–geological factors (such as the logging environment, logging instrument precision and calibration, the artificial operation etc.) as much as possible by some mathematic methods.
In principle, the first way is most effective way, but it takes a lot of manpower, material and time resources, and it unable to make full use of existing data; the second way refers to the use of high resolution processing on mathematical processing to improve the vertical resolution and radial resolution of logging curve, eliminate the influence factors of surrounding rock, borehole and mud, restore the true value of formation logging parameters [3].
