North China basin is a large Mesozoic to Cenozoic sedimentary basin in eastern China. A result of strong block-faulting activities, the inner part of the basin reveals the characteristics of multiple uplifts and depressions. Each depression is generally an independent exploration unit. The practice of exploration in recent years has proved the following: taking each depression as an individual unit, the basic geologic framework and evolutionary history are quickly determined. This is very important in order to achieve the best effects in petroleum exploration. Jizhong depression is located at the western part of the North China basin. This area is about 25,000 km/sup 2/ (9650 mi/sup 2/). Extensive seismic surveys and several hundred exploration wells have been completed during the past few years, resulting in the discovery of Renqiu and other oil fields. Taking the Jizhong depression as an example, the writer has considered the four following problems: Pre-Tertiary fault blocks and their distributional form, Some characteristics of block-faulting activities; Block-faulting in relation to the controlling of Tertiary sediments and structures; and the types of oil and/or gas pools. In the future, the exploration of the buried-hill gas or oil pools will continue. This should expedite the exploration for the other two types of oil or gas pools. In addition, we should pay much attention to exploration for Tertiary stratigraphic-lithologic oil or gas pools.
