Abstract: The geo-steering technology has achieved good results in the development and application of Mahu sand gravel reservoir in Xinjiang oilfield, and the oil layer drilling rate has been greatly improved. Due to the large difference in the cost of different geo-steering technology, and the need of oilfield development investment control, according to the geological characteristics of different well areas in Mahu, the combination of edge detection technology and conventional LWD geo-steering technology is adopted to ensure the oil production. Under the condition of layer drilling rate, the development cost is effectively controlled. Based on the analysis of the characteristics and differences between the conventional LWD geo-steering technology and the exploration geo-steering technology, this paper introduces the application of the exploration geo-steering technology in Mahu block. Combined with the geological characteristics and reservoir characteristics of the Mahu block, it puts forward the optimization scheme of the application of the exploration geo-steering technology and the conventional LWD geo-steering technology in different horizontal wells, so as to select the best cost-effective geo-steering technology for horizontal wells in the later stage drilling in this block.
