什邡-德阳-广金地区蓬莱镇组致密气藏储层四性关系及有效厚度下限研究
|
摘要
为了提高什邡-德阳-广金地区蓬莱镇组有利区域的预测精度,利用岩心、测井等资料,对蓬莱镇组的岩性、物性、电性和含气性四性特征及其相互关系进行了研究。结果表明:研究区致密储层气的富集程度主要受储层岩性和物性的影响;选取自然伽马、电阻率、自然电位和声波时差等电性资料,建立岩性、物性及含气性测井解释模型,并将测井解释成果与岩心分析结果进行对比检验,发现吻合较好,即所建模型可靠。最终确定了气藏有效厚度划分标准,提高了气水解释的符合率。
In order to improve the accuracy of predicting the favorable area of Penglaizhen Formation in Shifangdeyang-guangjin area,based on the data of core、logging,etc,we studied the characteristics and relationship of lithology、physical property、electrical property and hydrocarbon showings of Penglaizhen Formation. The results show that the degree of the tight gas reservoir enrichment is mainly influenced by lithology and physical property of reservoir. We choose natural gamma cure、resistivity curve、spontaneous potential curve and acoustic time curve data,established lithology、physical property and hydrocarbon showings well logging interpretation model. Then we compared the log interpretation results with the core analysis results,they are in good agreement which means the models are reliable. Ultimately we determined the effective thickness deviding standards of the gas reservoirs,which improved the coincidence rate of the gas-bearing formations of interpretation.
