地层倾角测井能寻找不对称背斜构造、盐丘构造、断层构造、不整合构造,为勘探背斜油气藏或隐蔽油气藏提供可靠的地质基础资料。本文提出8种褶曲模型、3种盐丘构造模型、11种断层构造模型……的地层倾角矢量图模式,产以中原油田地层倾角测井资料为例,在3口井(文33—50、刘1、开38)中各自找出一个背斜构造,在新文401井与文215井之间找出文23盐丘窿起构造,在17口井中找出各类断层,在开38井找出沙河街与中生界地层之间有个角度不整合构造。用地层倾角测井资料还可判断砂体类型、砂体延伸方向、增厚方向、古水流方向。文中对文152井两个砂体作了初步分析。地层傾角测井资料还可以提供沉积学方面的许多信息,本文以文152井为例,提出用傾角测井资料区分岩性、区分岩性均质与非均质情况、确定岩层界面特征等。在石油勘探与开发中,地层傾角测井资料结合其它资料进行综合分析,能大大提高石油勘探与开发效率。
Stratigraphic dip logging can find asymmetric anticline structure, salt dome structure, fault structure and unconformity structure, and provide reliable geological data for exploration anticline or subtle reservoirs. In this paper, 8 kinds of fold model, 3 kinds of salt dome tectonic model and 11 kinds of fault tectonic model ... are presented. Based on the data of stratigraphic dip logging data of Zhongyuan Oilfield, Liu 1, Kai 38), respectively, to find an anticline structure, between the Xinwen 401 well and the Wen 215 well to find Wen 23 salt uplift structure in 17 wells to find all kinds of faults in 38 wells Find an angle between Shahejie and Mesozoic strata unconformity. Sedimentary logging data can also determine the sand body type, sand body extension direction, thickening direction, ancient water flow direction. In this paper, we have made a preliminary analysis of two sand bodies in Well 152. The data of dip logging can also provide much information on sedimentology. In this paper, taking Well 152 as an example, this paper proposes to distinguish lithology by dip logging data, distinguish lithologic homogeneity and heterogeneity, and determine the characteristics of rock strata interface. In petroleum exploration and development, the comprehensive analysis of formation dip logging data combined with other data can greatly enhance the efficiency of petroleum exploration and development.
