塔巴庙区块气层录井参数分析研究

塔巴庙区块气藏属于低压、低渗气藏,储集层物性差异大、含气级别高,但含气非均质性强,录井解释评价困难。针对这一问题,开展了综合判断储集层物性和含气性方面的研究,分别探讨了钻时与全烃、钻井液性能与全烃、钻井液粘度与全烃、气测显示与测井参数和烃组分与气显示之间的关系,分析了其相关性及其在塔巴庙区块气层解释评价中的意义及作用。通过相关性研究,不但摸索出定性解释评价气层的方法,同时为今后深入研究录井相关参数关系,探索其内在规律,为实现准确解释评价储集层奠定了基础。

Analysis and study on gas zone logging parameters in Tabamiao Block.

Tabamiao Block belongs to low pressure and low permeability gas reservoir, it features with large difference on reservoir physical properties, high oil and gas bearing level, but high gas bearing heterogeneity, and it is hard for mud logging interpretation and evaluation. According to this problem, the author carried out the study on judging reservoir physical properties and gas bearing properties comprehensively, discussed the relationships respectively of drilling time and total hydrocarbon, drilling fluid properties and total hydrocarbon, drilling fluid viscosity and total hydrocarbon, gas logging show with well logging parameters and hydrocarbon components and analyzed their correlativity and their meaning and function in gas zone interpretation and evaluation in Tabamiao Block. By the correlativity study, the author found out the quantitative gas interpretation and evaluation method, at same time established the basis for studying mud logging parameters correlativity further, discovering its inner rules and realizing accurate interpretation and evaluation on the reservoirs.
