摘要
渤海油田潜山界面类型较为复杂,有多种潜山披覆组合类型,井场潜山界面识别的准确性直接影响到储集层保护、工程施工安全和作业时效。X射线荧光元素录井可以随钻分析地层元素含量变化,具有分析周期短、数据全、时效性强的特点。通过对渤海油田6个典型区块潜山元素特征进行分析研究,确认了渤海探区16种进潜山类型,多种元素标志组合特征,从X射线荧光分析数值、曲线及元素组合等方面对比岩性剖面等地质资料,建立了一套适合渤海油田的潜山界面元素组合识别模式及判别方法。实际验证表明,该方法的实施,不仅可为选择合理的钻井方式、及时调整钻井参数提供依据,而且在油气勘探开发中发挥了重要作用。
The types of buried hill interface in Bohai Oilfield are complex,and there are many kinds of buried hill drape combination.The accuracy of identification of buried hill interface in well site directly affects reservoir protection,engineer ing construction safety and operational aging.X-ray fluorescence element logging can analyze formation element content changes while drilling,which has the characteristics of short analysis period,complete data and strong timeliness.Based on the analysis of element characteristics of buried hill in 6 typical blocks of Bohai Oilfield,16 types into the buried hill and combination characteristics of multiple element markers in Bohai exploration area are confirmed.The geologic information such as lithological profiles are compared with the X-ray fluorescence analysis values,curves and element combinations,and a set of identification patterns and discriminant methods of buried hill interface element combination suitable for Bohai Oilfield is established.The practical verification shows that the method can not only provide the basis for selecting reasonable drilling methods and adjusting drilling parameters in time,but also play an important role in oil and gas exploration and development.
