Aiming at more and more complex exploration target, the petroleum exploration techniques develop and perfect continuously. This paper mainly introduce seismic exploration technology, drilling technology and well-logging technology. The target finding by seismic prospecting in complicated mountainous area, desert and loess plateau，high- precision 3D seismic acquisition technique, which are the main seismic exploration technology developed in these years, are covering the Onshore exploration field in China. Seismic prospecting in Complicated Mountainous Area played an key role in deepening understanding the complexstructural model of Kuche foreland in Tarim basin, finding Dabei3 and Keshen2 gai field, implementation of Dina gas field's reserve scale. It is also give important help to imporve trap identification precision in steep structure region of Eastern Sichuan, realize significant breakthrough in Carboniferous, Feixianguan oolitic shoal and Changxing reef reservoirs. Seismic prospecting in desert works well in Tazhong region, Tarim basin and Kelameili region, eastern Junggar Basin. The new data signal-to-noise ratio is improved obviously, which gave support for the implementation of Tazhong oil & gas field and Kelameili gas field's reserve scale. Seismic prospecting in loess plateau play an important role in Xifeng, Jiyuan, Baibao oil fields' exploration and south Sulige gas field's expleration. High- precision 3D seismic acquisition technique pushes forward the new discoveries in complex fault block oil reservoir in oil-rich sag and stratigraphic-lithologic reservoirs in Eastern China. Air drilling, under-balanced drilling, vertical drilling are three newly arisen techniques used onshore of China, which has played an important role in improving drilling speed, protecting reservoir formation from pollution, detecting the oil/gas show in time, and reducing complex accident. So they should be applied widely in the future exploration. With the the constant perfection and scale application, in Longgang region and Northeast of Sichuan basin, by using air drilling the drilling speed is promoted quickly and the drilling cycle is shorten obviously. In Qianmiqiao gas field of Dagang, Xushen gas field of Daqing, Qiongxi gas field of Sichuan, under-balanced drilling has good effect on detecting the oil/gas show in time and promoting drilling speed. In the high and steep structures of Kuche in Tarim basin, Northeast of Sichuan basin, vertical drilling has realized deflection controlling and fast drilling. The modern well-logging technique includes the new generation open hole logging, logging while drilling and cased hole logging etc., among which the new generation open hole logging is used the most widely. The new generation open hole logging is characterized by regular arrays, spectrum, energy spectrum measurement, and imaging display. The imaging display technique, which highly improved the logging evaluation ability of the fractured, conglomerate, igneous rock, metamorphic rock, low permeability reservoir and low resistivity pay zone, successfully interpreted a batch of difficult exploration well and found complex reservoirs. logging while drilling is the fastest developing well-logging technique, which can evaluate formation and carry out geo-steering. Geo-steering means by supervising the ratio of distances from the horizontal well trajectory to the upper and lower interfaces, we can control the bit position and drilling direction. The new generation cased hole logging can be used to formation evaluation in cased hole. Especially when we cann't get open hole logging data in accident well，we can evaluate the reservoir via cased hole logging.
