斯仑贝谢测井公司的一个测井队自1984年12月起在大庆服务近两年,共测井51口。实际资料表明,斯仑贝谢测井系列较完善,仪器指标先进,刻度严格。所测资料较准确可靠。通过服务不仅提高了我们技术人员的水平,而且解决了一批国产仪器解决不了的问题。利用自然伽马能谱测井确定泥质含量,研究泥质成分,为解释模型及参数选择、储层评价、沉积环境研究提供了重要依据。RFT用于探井油气水层判断、调整井中厚层层内水淹等级划分及小层压力计算取得突破。用EPT资料对地层水矿化度变化大的井段判断油水层以及划分有效厚度取得较好效果。探井解释符合率达75％左右,比国产仪器测井资料解释提高5～7％。初步总结出了裂缝识别方法,为深层油气层研究提供了重要方法。通过对SHDT资料的分析,初步建立了沉积模式和物源模式,并对个别地区提出了有利勘探井位。但是,对调整井水淹层解释、裂缝中流体性质判断及薄层解释尚无一套完善的方法,有待今后进一步研究。
A logging team at Schlumberger Well Logging Company has been serving Daqing for nearly two years since December 1984, logging a total of 51 wells. The actual data show that the Schlumberger logging series more perfect, advanced instrumentation, graduated. The measured data is more accurate and reliable. Through service not only to improve the level of our technical staff, but also to solve a number of domestic equipment can not solve the problem. The use of gamma ray spectrometry to determine shale content and study the composition of shale provides an important basis for explaining the model and parameter selection, reservoir evaluation and sedimentary environment. RFT is used to determine the water, oil and gas wells in exploration wells, and to make breakthroughs in adjusting the classification of submergence gradients and calculation of the sub-layer pressure in the thick wells in the wells. Using EPT data to judge the oil-water layer and the effective thickness of the section with large variation of salinity of formation water, good results are obtained. Exploration wells explain the coincidence rate of about 75%, than the domestic instrument logging data to explain the increase of 5 to 7%. The method of fracture identification is initially summarized, which provides an important method for the research of deep reservoirs. Through the analysis of SHDT data, the sedimentary model and provenance model have been initially established and favorable exploration wells have been proposed for some regions. However, there is not a complete set of methods for adjusting well water flooding interpretation, fluid property judgment and thin layer interpretation in fractures, which needs further study.
