Background
The exploration and development of deep-water deep oil and gas resources has the characteristics of high safety risk, high operation cost and high technical difficulty, and due to insufficient mastering and cognition of deep-water deep stratum information, various underground accidents are often caused by gas invasion, solution gas invasion, rock debris invasion and other invasion in the exploration and development process, so that early monitoring and control of invasion are one of the keys for avoiding major accidents such as blowout and the like.
The existing intrusion monitoring device is mainly used for monitoring based on an ultrasonic principle, for example, a Chinese patent document CN 111364979A discloses an underground gas intrusion monitoring system based on ultrasonic, the method separates gas, liquid and solid three-phase flows through turbine combination, then a self-receiving bicrystal probe and a single-shot/single-shot oblique probe are used for receiving an acoustic wave signal, and early gas intrusion monitoring is realized, but the method has several defects: firstly, the device is complex, a turbine and a turbine protection device are required to be installed, and the underground complex working condition cannot be met; secondly, the acoustic wave signal is transmitted through a shaft, the intensity of the acoustic wave signal is greatly attenuated, thirdly, only a small part of the acoustic wave signal passing through the shaft is reflected back to be received by a bicrystal probe after encountering bubbles near the shaft wall, most of the acoustic wave signal is dispersed in a refraction and scattering mode, and the installation angle of a single crystal inclined probe cannot be ensured to be in accordance with the migration track of the bubbles at the bottom of the shaft, as disclosed in China patent document CN 115596430A, the main body of the device is an arc-shaped plate, an acoustic wave generator and an acoustic wave receiver are symmetrically arranged at the outer side of the arc-shaped plate, the device is required to be poured and fixed in a cement ring in order to avoid the influence of stratum environment, and has a plurality of defects in the use process, firstly, the device can realize effective monitoring of the gas invasion, but cannot be repeatedly used because the device is poured in the cement, secondly, the ultrasonic wave detection gas invasion principle is based on the fact that the ultrasonic wave signal is scattered, absorbed and attenuated at the position, and finally whether the gas invasion occurs through the change of the received signal at the bottom of the shaft, however, in the oil well production process, small solid particles such as rock debris can be generated, and the small solid particles can also act on ultrasonic signals, so that whether the rock debris or bubbles affect the ultrasonic signals cannot be accurately judged, and the accuracy of an ultrasonic detection method is further affected.
The existing ultrasonic monitoring gas intrusion method has good response characteristics only for multiphase flow with obvious acoustic impedance interfaces (such as bubbles with physical forms) due to the principle limitation, but has insignificant response characteristics for gas intrusion in a dissolved state.
Accordingly, there is a need for a reusable intrusion monitoring device that can cope with complex downhole conditions to avoid major accidents during drilling.
