Problems solved by technology

Research on domestic and foreign data shows that although there are various forms of well control simulation experiment wells and simulation devices at home and abroad, and their design schemes have their own merits, so far there is no well control simulation experiment device that can cooperate with classroom education, improve hands-on ability and complete open experiments. , it is necessary to develop a small, simple, visual, and operable well control simulation teaching experiment device that can cultivate students' hands-on ability and deepen their understanding of theoretical knowledge

Embodiment Construction

[0022] Such as figure 1 As shown, the drilling well control simulation teaching experiment device mentioned in the present invention includes five parts: a wellbore simulation system, a drilling fluid circulation system, an aggravated drilling fluid circulation system, a gas-liquid mixing circulation system, and a computer data processing system.

[0023] The wellbore simulation system includes a plexiglass inner tube 1 for simulating a drill string, an plexiglass outer tube 2 for simulating a casing, an internal rotating motor 3 for providing rotation power of the drill string, and a check valve 4 . The upper part of the plexiglass inner tube 1 is connected with the check valve 4 and the inner rotating motor 3, which can simulate the rotation of the drill string. The function of the check valve 4 is to only allow the drilling fluid to flow downward from the top, but not to allow the upward flow; the check valve 4 can be dismantled. The upper and lower parts of the wellbore c...

Abstract

The invention relates to a drilling well control simulation teaching experimental device. The technical scheme is that the drilling well control simulation teaching experimental device comprises the five parts of a wellbore simulation system, a drilling liquid circulation system, a weighted drilling liquid circulation system, a gas-liquid mixing circulation system and a computer data processing system; the drilling liquid circulation system comprises a drilling liquid storage tank; the weighted drilling liquid circulation system comprises a weighted drilling liquid storage tank; the gas-liquid mixing circulation system comprises a stratum liquid phase liquid storage tank, a gas compressor and a gas-liquid two-phase mixture. The beneficial effects of the invention are that the drilling well control simulation teaching experimental device is simple and easy to assemble, can deepen students' understanding and mastery of the drilling well control theoretical knowledge, and can also perform similar simulation operation on the drilling well control site, thereby providing the students with an immersive feeling, improving their basic skills of drilling well control technology, achieving the purpose of engineering practice, and avoiding risk factors brought by on-site operation.

Description

technical field [0001] The invention relates to an experimental device in the field of oil and gas development, in particular to a drilling well control simulation teaching experimental device. Background technique [0002] Drilling engineering is a professional compulsory course of petroleum engineering, which requires high practicality. Its characteristic is that the course content is closely related to on-site production, and theory is closely connected with production. Due to the expansion of enrollment scale and the limitation of actual production conditions on site, the difficulty of drilling production practice and practical teaching for students is increasing, especially in oil drilling, which is a high-risk industry. During the process of site practice, students can only study in the form of visits, not Carry out practical operation training. Due to students' lack of understanding of the actual process of the site, when it comes to issues related to the site, t...
