摘要/Abstract

摘要： 为了达到随钻判别铂金箱体的目的,以四川盆地黄瓜山构造龙马溪组为研究对象,利用气测参数、特殊录井数据与测井数据开展相关性研究,从页岩气铂金箱体录井响应特征诸参数中确认岩屑TOC、岩屑硅元素含量、岩屑钙元素含量及龙马溪组纵向位置4个录井响应特征明显的参数,钻进时依据这4个参数并结合其余录井响应特征可实现综合判别铂金箱体。研究表明:气测数据、自然伽马能谱录井数据及X射线荧光(XRF)元素录井数据与钻后测井解释数据的铂金箱体参数相关性较高;应用气测录井、自然伽马能谱录井及XRF元素录井等模型所确定的H 202井区铂金箱体录井响应特征,能够达到随钻判别铂金箱体的目的。将研究成果应用于该井区3口水平井,页岩气铂金箱体录井解释平均符合率达95.9%,说明铂金箱体录井响应特征具有实用性。

Abstract: In order to solve the problem of discriminating shale gas platinum box while drilling, the Longmaxi Formation of Huangguashan structure in Sichuan Basin was taken as the research object, and the correlation study was carried out by using gas logging parameters, special mud logging data and logging data. From the multiple mud logging response characteristic parameters of shale gas platinum box, four parameters with obvious mud logging response characteristics, namely, cuttings TOC, cuttings silicon content, cuttings calcium content and the longitudinal position of Longmaxi Formation, are confirmed. The platinum box can be comprehensively discriminated according to these four parameters and other mud logging response characteristics during drilling. The research shows that the correlation coefficient between the platinum box parameters in gas logging data, natural gamma ray spectrum logging data and XRF element logging data and those in post drilling logging interpretation data is high. The response characteristics of the platinum box mud logging in H202 well area determined by gas logging, natural gamma ray spectrum logging and XRF element logging models can achieve the purpose of discriminating platinum box while drilling. The results of this study are applied to three horizontal wells in this area, and the average coincidence rate of platinum box mud logging interpretation is up to 95.9%, indicating that the response characteristics of platinum box mud logging are practical.

Key words: shale gas, platinum box, correlation, gas logging, natural gamma spectroscopy, element logging, response characteristic
