The paper analyses deeply on the lateralfault seal by clay smear on the basis of the precensors studies.
在前人研究的基础上，对粘土涂抹作用造成的断层侧向封闭性进行了深入分析。

Fault is the key factor of subtle traps to oil accumulation, and has the function of linking reservoir and lateral sealing.
断层是隐蔽圈闭成藏的关键因素，能起到沟通油源和侧向封堵的双重作用。

It is practically shown that both horizontal fault distribution and lateral reservoir variation etcetera can be seen distinctly from the seismic data which have undergone derivation processing.
