摘要:

冀中坳陷的油气勘探,如果从1956年在牛驼镇凸起上开钻固1井算起,已超过30年了。回顾这个历程,是很有必要的。

Abstract:

The Jizhong Depression is famous for the discovery of Renqiu buried-hill oilfield. This achievement was gained after nearly 20 years of hard exploration.To review the discovery process, there are two respects worth noting: 1. Itshould be based on the option of the most favourable exploration objects with-in the whole region in stead of concentrating too early efforts on some localareas in the early stage of exploration: 2. Choosing the object bed for explo-ration should be fit in with the drill capacity and search for more oil-bearingsets for test in stead of restricting the test within some sets subjectively sothat it may enhance the discovery of oil and gas fields. The output of Renqiu oilfield has decreases progrossively after more than ten years of production. To develop hydrocarbon exploration and open up newprospect, we ought to make more exploration in lower explored places in the Jizhong Depression and draw a plan to find new hydrocarbon-bearing sets. There are a certain number of sedimentary subdepressions which are notsmall in area developed in the Tertiary and Mesozoic to be explorated in the depression. It is estimated that the decreasing trend of crude oil out put in the Jizhong Depression at present could be changed and North China oil fields will get a new development so long as suitable work load is thrown in.
