[Abstract]:The production of onshore oil and gas wells is more complicated, combined with the production of ultra-deep oil and gas fields and offshore oil and gas fields, drilling technology has been further developed. In this process, a new type of deep well drilling equipment with high automation level and high performance is needed. Ac frequency conversion point drive drilling rig is the most scientific drilling equipment in deep wells. This equipment has advanced structure simplification technology, excellent output characteristics, good safety, adaptability and reliability. The users are very welcome and widely used. Is the development direction of deep drilling rig. The research object selected in this paper is 50DB drilling rig in Liaohe Oilfield. By summarizing and arranging the relevant research results of hydraulic system of drilling rig in China and abroad at present, Based on the related design of 50DB in Liaohe Oilfield and the load characteristics of the system in the following aspects, the hydraulic system of drilling rig is studied. Then, this paper simulates the core loop of the rig with the simulation system, and establishes the model, which provides the theoretical basis and practical reference value, and provides a great help for the design and simulation of the hydraulic system of the 50DB drilling rig in Liaohe Oilfield. The application of dynamic design in hydraulic system design of drilling rig is proved to be feasible. The main contents of this paper are as follows: according to the current situation of domestic and foreign research, this paper mainly introduces the background and significance of the research, and discusses the characteristics and design of 50DB drilling rig. The related contents of hydraulic system of drilling rig are analyzed, and the traditional hydraulic system of drilling rig is analyzed with examples. The hydraulic system of 50DB drilling rig in Liaohe Oilfield is designed through the feed loop of power head, rotary hydraulic circuit of power head, walking and rolling field control circuit, auxiliary hydraulic circuit, hydraulic circuit of mud pump and so on. The main parameters of hydraulic system of 50DB drilling rig in Liaohe Oilfield include the main technical parameters of drilling rig, hydraulic power element and the selection of hydraulic actuator. The simulation of 50DB hydraulic system in Liaohe Oilfield is carried out in the process of design, and the simulation analysis of drilling hydraulic system is carried out by using AMESim software, which provides the basis for improving the design of hydraulic system. Finally, the direction of further work is prospected.
