Self-adaptive drilling measurement and control system of deep sea core drill

Abstract

The invention discloses a self-adaptive drilling measurement and control system of a deep sea core drill. The self-adaptive drilling measurement and control system comprises an overwater control system and an underwater measurement and control system which are in communication connection; and the overwater control system comprises a first communication module, an industrial control module and a man-machine interaction module, the first communication module is in communication connection with the industrial control module and the underwater measurement and control system, and the man-machine interaction module is in communication connection with the industrial control module. According to the self-adaptive drilling measurement and control system, parameter feedback information such as the rotating speed and the bit pressure is added into a drilling execution module of the drill, a self-adaptive control algorithm is correspondingly fused into a proportional valve control module of the underwater measurement and control system, geological attributes of a drilling area block are recognized, the theoretical drilling speed under official big data in the geological environment is matchedin a self-adaptive mode, constant-rotating-speed cruise drilling is conducted, and the drilling efficiency and the drilling effect are effectively improved.

Description

Technical field [0001] The present invention relates to a deep sea rock core drilling machine adaptive drilling measurement and control system. Background technique [0002] The seabed rock core sampling rig is a special equipment for the deep-sea geological drilling of deep-sea geological exploration and marine geological science research, suitable for census exploration in the seabed, and has a completely different ways of working with the usual drilling or drilling platform. When the seabed rig is working underwater, it requires a umbilical cable with load carrying vessels to achieve remote energy supply and communication control. [0003] Since the first completion of the experimental sample in 2003, more than 300 effective station sampling have been completed, and more than 300 effective stations have provided a variety and effective geological sample for deep sea geological exploration, further consolidate my country. Investigation status in the international deep sea scien...

Problems solved by technology

At present, the working mode of the existing subsea drilling rigs is open-loop control. During the drilling operation of the drilling rig sitting on the bottom, it completely relies on the on-site professional engineer to perform manual remote control operation, and manually adjusts the drilling pressure, rotation speed and speed according to the data feedback of various underwater sensors. Flush pump flow and other parameters to complete the drilling operation, the whole operation is complicated, the requirements for operators are high, and a certain degree of automation is lacking
