Abstract


The LWD data preprocessing while drilling is an important task of data interpretation . This paper -based the LWD system developed by the Shengli oilfield drilling Institute , data preprocessing technology research to improve SDRI-LWD LWD accuracy of the information . This article made ??the following work : First, the SDRI-LWD LWD system structure , functions and features , content and process of the proposed SDRI-LWD data preprocessing . Discussed in detail SDRI-LWD the LWD system data preprocessing key techniques and algorithms, and design of the software process flow . Second, based on the depth of the measurement method and measuring the impact of factors proposed an adaptive depth correction technology to achieve accurate depth measurement . Three SDRI-LWD downhole data upload basic methods , and design a highly efficient and reliable measurement data encoding . According to the basic principles of vertical depth correction and oblique deep - vertical depth conversion method designed vertical depth - measuring the value of accurate conversion process . According to the the LWD data error sources and characteristics to determine the smoothing filter filter factor applies to SDRI-LWD . The one-dimensional Akima piecewise cubic polynomial interpolation algorithm , the curve interpolation function calculation method is designed to avoid the drilling rate changes , the data transfer rate and low curve burr . Fourth, establish a memory data processing flow , time-based , the formation depth - memory data standards file . Establish a reasonable LWD scale flow and money transfer method LWD instrument calibration , scale , testing , through traceable wireline industry standards , and achieve SDRI-LWD and wireline logging instruments measure the standard uniform . The practical application results show that the data preprocessing technology with SDRI-LWD logging while drilling the LWD data interpretation can be effectively used .
