Abstract: The detection and evaluation technologies of underground reservoirs and fluid properties including plane detection and depth detection are new unconventional hydrocarbon detection and evaluation technologies developed recent years. In order to find out the best gas-bearing regional distribution and depth range of Chen-jiazhuang gasfield,field tests were conducted in the gas well district. The practice proved that the detection results of gas-bearing range had better correlativity when compared with the interpreted results of seismic bright spots. As with portable,low-cost and high-efficiency features,these technologies have great prospects for popularization.
