本文利用岩心、测井曲线等综合资料，依托夹层特征刻画单砂体界限，利用野外露头观察及测井曲线特征，结合勘探开发生产需求，将砂体连续性划分为两种类型：连续叠加型和间隔叠加型。根据砂体发育期次划分为两种类型：侧向单层型和多期互层型。并表征了纵向及平面砂体展布特征，为后期开发调整提供基础。

Based on the comprehensive data such as core and logging curve, the boundary of single sand body is described by relying on the characteristics of interlayer, and the continuity of sand body is divided into two types: continuous superposition type and interval superposition type by using the characteristics of field outcrop observation and logging curve and in combination with the needs of exploration, development and production. According to the development stages of sand body, it can be divided into two types: lateral single-layer type and multi-stage interbedding type. The distribution characteristics of vertical and plane sand bodies are characterized, which provides a basis for later development and adjustment.<br>

In this paper, the boundary of single sand body is depicted by using comprehensive data such as core and logging curves, and the continuity of sand body is divided into two types: continuous superposition type and interval superposition type by using outcrop observation in the field and logging curve characteristics, in combination with the demand of exploration, development and production. According to the development stages of sand bodies, they can be divided into two types: lateral monolayer type and multi-stage interbedded type. It also characterizes the distribution characteristics of longitudinal and plane sand bodies, and provides a basis for later development and adjustment.
