Abstract Drilling rate of high-quality reservoir in horizontal well is one of the key factors for high production of single well, which directly affects the production of horizontal well. Based on seismic, drilling, well logging, mud logging and geological orientation data, the authors summarized the influence factors of drilling rate in horizontal well reservoir with different reservoir type, and put forward the application of the integrated of positioning, measurement, logging and guiding in improving the drilling rate of horizontal well reservoir, through the mathematical statistics and analysis of horizontal well drilling rate in the main block reservoirs of Sinopec. Besides, the typical application examples are listed, and the future research direction of integrated of horizontal well positioning, measurement, logging and guiding is summarized. The results show that the average drilling rate of petrochemical horizontal wells in Sinopec in 2021 is 93.7%. Due to the constraints of complicated geological conditions, long blind area of measurement and control instruments, and insufficient professional integration, this drilling rate still needs to be improved. The integration measurement technology is able to make a fusion of professional technology and information integration, including geology, seismic, directional, logging and guiding. Combing with the online-experts supports and linkage between front and back, integration measurement technology can be used effectively to solve the technical problems in drilling horizontal well, such as complex local micro structure, fault development and severe change of lithology in reservoir plane, and well trajectory with easy to layer, easy to touch water, which improve the drilling rate of horizontal wells. The next step of the integration measurement technology focus on the establishment of expert's team in different regions, strengthening the deep integration of multiple specialties, and increasement of application of new technologies, which has great significance to the exploration and development of oil and gas fields in China.

Key words： horizontal well reservoir drilling rate integrated of positioning measurement logging and guiding drilling technology
