A Study On Fine Evaluation Way Of Mud Logging And Method To Optimize Perforating Hole Section For Horizontal Well

Through collecting the 2009 in jilin area on the horizontal well logging data, including relevant geological geological logging, electrical measurement, geochemical logging, gas chromatography, quantitative fluorescence analysis and try oil material, made from different areas and different horizon of horizontal section of the logging parameter variation characteristics comparative analysis, the authors pertinently choose those correlation is stronger, the discriminant effect good parameters. Which reflect the lithology and oil-bearing parameters mainly from logging parameter choice; Reflect physical parameters from logging parameters in selected. Then from the parameters of after filtered in different regions was established according to the evaluation standard, summarized the horizontal well logging careful evaluation method of the specific steps are as follows:(1)Tthe combination cutting logging and well logging curves for lithologic section position.(2)Uuse gas logging C1 curve of level of fine division,.(3)Uusing screening of record, logging evaluation parameters to differentiate good small layers from oil-bearing oily, physical properties and characteristics of several aspects such as fine evaluation, evaluation standard interpretation conclusions based on that,.(4) waterflooding revolutionary of horizontal Wells need to conduct water flooded degree of qualitative identification.Implement 2009 every mouth perforating hole section of total length and after production of dynamic data, a relatively long interval and a short interval perforation after modification of horizontal liquid producing, oil production status, from the initial production and the current analysis, the article in two stages, long and short horizontal Wells in jilin area reconstruction quality section perforating malpractice, draw some regularity understanding, further proved perforating hole section optimization and the necessity of establishing a set of based on logging data, combined with the logging and related regional geological information of perforating hole section, establishes the preferred method for optimizing the specific principles are as follows:(1)Tthe logging technology material are significantly relatively high value, third-party lithology and oil-bearing;.(2)Llogging data in the electrical and physical properties on high resistivity and better hole perjmeability.(3)Pperforating hole section to avoid made selection of inclined section and the trajectory of unstable interval, in trajectory stability of interval within selected.
