Abstract

The invention discloses a high temperature drilling experiment device. The high temperature drilling experiment device is composed of a high temperature fluid chamber, a rotary drilling system, a flushing fluid circulating system and a drilling control recording system; the high temperature fluid chamber and the flushing fluid circulating system are fixedly arranged in the rotary drilling system respectively, and the drilling control recording system is connected with the high temperature fluid chamber, the rotary drilling system and the flushing fluid circulating system through cables respectively. According to the high temperature drilling experiment device, a high temperature formation condition is simulated in a laboratory for drilling experiments, small-size drill bit rock drilling experiments are carried out, mechanism changes of high temperature formation drilling rock breaking and drill bit abrasion features are researched through data collection for the rock breaking effect and efficiency, drilling parameters and the like, the drilling rules are summarized to be used for guiding drill bit structure design and drilling parameter selection of an ultra deep well and a hot dry rock formation, and a basis is provided for improving the coring efficiency and reducing the cost.

Description

technical field [0001] The invention relates to the field of drilling experiments, in particular to a high-temperature drilling experiment device. Background technique [0002] With the development of industrial economy, the earth's shallow conventional energy and resources are exhausted, and the exploration and development work continues to develop into deep and complex strata. Deep geological exploration is also the need of human scientific exploration. Studies have shown that for every 1,000m depth increase, the formation temperature will rise by 30°C on average, and the formation temperature at the bottom of wells drilled over 10,000 meters will exceed 300°C; the development of hot dry rock is currently a hot spot in the development of new international energy, and has broad application prospects. The rock formation temperature generally exceeds 200°C, and the higher the temperature, the greater the development value. However, rock mechanics studies have shown that as t...
