Study on automatic degasification system of hydrocarbon component in rock cuttings

With the development of well drilling technique and the reform on drill bit technique, each oil field has adopted new PDC drill bit to smash rock cuttings. However, the severely mixed cuttings have greatly increased the difficulty in collecting samples through traditional geochemical logging technique. Based on the further study on geochemical logging and gas logging techniques, a new approach is presented in the paper to analyze rock cutting samples by hydrocarbon component through complete degasification. In addition, using PLC programmed control, an automatic degasification system of hydrocarbon component in rock cuttings is developed, which has achieved good testing results. The precision of exploration for petroleum and natural gas is hereby enhanced.
