Geological Background

Heiyu Lake zone of Daqing is located in the southwest hollow borderland of Heiyu Lake and on the arching transitional zone of Daqing placanticline. Based on the geological background of Heiyu Lake, this paper analyzes the landform, the regional geological structure, the formation lithology and the irruptive rock and other metallogenic conditions in detail. The indispensable geological conditions for forming geothermal field in layers were summed up. Combining with the development characteristics and geophysical data of formation, the bore hole site of geothermal well and target stratum were ascertained. The four major elements of forming geothermal resources in this region were confirmed by carrying out geothermal drilling.

Abstract Single polycrystalline diamond compact (PDC) cutting is a practical technique to understand the rock-tool interactions in drag-bit type geothermal drilling operations. This paper introduces a rotary cutting method to determine specific cutting energy (SCE) and compares it with the conventional linear cutting method. In this work, granite is selected to represent hard rock formations in geothermal drilling. Cutting tests are conducted on a CNC machine with a realistic cutting speed of 12.7 m/min and several chip loads ranging from 0.08 to 0.25 mm. The cutting force is measured using a dynamometer, and then converted to SCE. The results show that the rotary method produces an inverse relationship between SCE and chip load, whereas the linear method shows the opposite. As a result, the produced SCE by the rotary method tends to be lower than that of the linear method at a higher chip load at and over 0.16 mm. The difference may be attributed to the cutting configuration and associated force components.
