喇萨杏油田新测井系列解释厚度精度影响因素分析

Affecting Factors of Effective Thickness Interpreting Accuracy Using New Logging Suite in Lamadian-Saertu-Xingshugang Oilfield

测井解释有效厚度精度如何将直接影响油田三次加密调整方案部署,针对用1983年和1990年研究的表外、砂岩和有效厚度电性标准解释新测井系列厚度偏少的现象,通过测井理论研究、现场实验、各类井网厚度对比分析等,从油田开发过程中钻井条件变化、测井系列变化、电性标准、含油产状下限等四个方面进行了详细的研究分折,从中找出了影响新测井系列解释厚度少划的原因。并提出了今后调整井要从提高钻井和测井质量、提高参数人员的综合解释能力等方面入手,建立完整的适用于新测井系列解释厚度的电性标准,保证各类厚度的解释精度,为三次加密调整提供可靠的基本参数。

How does the effective thickness accuracy of logging interpretation affects tertiary infill adjusting program deployment in oilfield directly? This paper focuses on the phenomenon that the e-leclronic criteria of untabulated, sandstone and effective thickness in 1983 and 1990 interpret the new logging suite and cut down its effective thickness, through logging theory study, field trial, all kinds of well patterns thickness and so on, based on four facts including drilling conditions, logging suites, electronic criteria and oil-bearing occurrence bottoms, study and analyze the details, then find out the reason. This paper also points out that adjusting well should improve the quality of drilling and well logging, the integrated ability of parameter interpreters etc. in the future, and establish the electronic criteria which are intact but applied to new logging suites, assure the accuracy of various thickness and provide with reliable parameters for tertiary infill adjusting program.
