The field of high temperature and high pressure is a key area of oil and gas exploration and development in China in the future, and it is also a very rich area of oil and gas resources. Unlike conventional oil and gas fields, high-temperature and high-pressure oil and gas fields are characterized by high-pressure systems, overlapping sand bodies and more complex gas-water modes. How to effectively predict the pressure, clear the distribution of sand and water, guide the smooth implementation of drilling operations, reasonable development plan is a key step. The authors analyze the reservoir in detail from pre-drilling pressure modeling technique, reservoir fluid fine identification and reservoir formation mechanism respectively. Finally, the Dongfang M gas field has a good effect after drilling, and the output and production capacity are all over expectations, especially for the development effect of low permeability breaking the ceiling of traditional low permeability reservoir development, and form a high temperature and high pressure implementation technology system to guide the subsequent development of similar areas.
