从遥感图象看楚雄盆地的断裂构造格局及油气勘探远景

A STUDY OF THE FAULTED STRUCTURE FRAMEWORK AND PROSPECT OF OIL AND GAS IN CHUXIONG BASIN BY REMOTE SENSING TECHNIQUE

楚雄盆地是一个勘探程度较低的含油气盆地,基底埋藏深,且经历的构造变动多而复杂,常规勘探手段的应用受到了局限。为此,本文对该盆地的遥感图象做了单因素及综合地质解释,其结果深化了对盆地构造内幕的认识。对遥感图象反映的盆地基底断裂结构及其对后期沉积的控制作用和由此引伸出的几个石油地质问题作了探讨。

The prospecting practise shows that an evaluation of a basin for its prospect of petroleum occurrence can not be concluded sufficiently from good structural shape and combinations of source rock, reservoir and capping beds, in addition interior texture of the structure should be known clearly, correct for a evaluation of the prospect of its oil and gas-bearing feature and a favorable places to start oil and gas exploration. The Chuxiong basin is a oil and gas-bearing basin with low degree of exploration. This basin subjected to complex movement for many times, thus the application of conventional exploration methods are limited to a certain extent. The author has made synthetic explanation of the remote sensing images of she basin by a combination of various simple factors. It is shown that the interior structure of basin can be considered more deeply only if some important conclusion are obtained and some important geological rules are summarized. This paper deals with fault texture of basin basement respondedby remote sensing images and its control action to later deposition, and geological problems relating to petroleum exploration derived from them.
