This paper proposes the exploration and application of ad - hoc network system for physical exploration in physical exploration production, aiming at solving the communication problems during the construction of physical exploration in network - free areas. By comparing and analyzing 4G mobile network, MESH ad - hoc network and BeiDou communication, a wide and narrow band dual MESH self - organized network system suitable for physical exploration production is explored to realize the full coverage of network in the network - less area of physical exploration and reduce the cost of network construction. The mobile APP of the Giscis system collects and uploads the production data in the process of survey, drilling and explosion that the Gisics system through the ad - hoc network equipment in the network - less area, solving the problem that the construction personnel cannot upload the collected data to the cloud in real time. Seismic team managers can command and dispatch the production through the real - time uploaded data, and when the field workers encounter emergencies, they can communicate with the team in time through the ad - hoc network equipment, so as to improve the efficiency and quality of the production of physical exploration and reduce the safety risks.

Impedance matching is a technical issue that cannot be ignored in electronic circuits. Whether the impedance of circuits matches not only affects the quality of signal transmission or acquisition, but also affects the safety of electronic circuits itself. In petroleum seismic exploration, the impedance matching of seismographs does not mean strict consistency of impedance in the analog signal acquisition channel, as the concept of impedance matching in the telecommunication field. Instead, it refers to the reasonable design for the input impedance of the acquisition station and the impedance of the geophone itself, in order to ensure that seismic signals can be acquired with high quality. This article mainly discusses the impact of impedance matching between the input impedance of seismographs and the internal resistance of magnetoelectric geophones on the acquisition effect of seismic signals, hoping to be helpful to peers.

The western exploration area is rich in oil and gas resources and has great exploration potential. The desert pushing road is the foundation and important step of geophysical exploration in the western exploration area. The traditional bulldozer operation involves many processes, which requires the close cooperation between the surveyor and the bulldozer driver. It is necessary to do a good job in the connection of the three processes of measurement, road pushing and measurement. The measurement is frequently lofted and staked out, with high labor intensity, many users, long production cycle and high cost. Through the study of high - precision navigation technology and positioning technology, a navigation and positioning system for bulldozer stakelessconstruction is developed. It can be used to improve the overall operation efficiency, save the process connection, reduce the time of waiting for each other, reduce the number of mechanical work and mechanical leveling, optimize the utilization of equipment, reduce the process and reduce the marking wear of the flag, reduce the on - site construction personnel, reduce the risk of operation and construction, assist the driver to complete the bulldozing operation accurately and efficiently, reduce the consumption input and complete more workload, save equipment rental, oil consumption, labor cost and material cost, promote the bulldozing operation from manual guidance to mechanical independent guidance, and improve the level of bulldozing operation. It is of great significance to realize the stakeless construction of bulldozer.

During the construction process of international oil exploration projects, some projects need to establish independent coordinate systems. In addition, the current high - efficiency exploration and acquisition projects need to adopt global high - precision real - time satellite station differential services to improve the acquisition efficiency, and the coordinate system of the control point needs to be consistent with the real - time satellite station differential results to minimize the impact of different coordinate systems. How to choose the precision single - point positioning online processing service for international projects has become a problem for international oil exploration projects. This paper describes in detail the data requirements and output results of four online processing services, namely, CSRS, AUSPOS, RTX and OPUS, which are often used in international projects. The data of international oil exploration projects at different times, different locations and different acquisition durations are sent to the four online services for processing, and the results show that the processing results of CSRS, AUSPOS, and RTX are more consistent, and the results are more consistent with those of AUSPOS, RTX, and AUSPOS. AUSPOS, RTX and CSRS have latitude and longitude rms (root - mean - square error) less than 0.0003 s and elevation rms error less than 0.030 m, OPUS processing results are more different from the other three, with latitude, longitude and elevation rms errors of 0.00038 s, 0.00051 s and 0.124 m, respectively. In the construction of the international project, it is necessary to take into account the reference frame, calendar elements, results reporting, timeliness and other factors, result reporting, timeliness and other factors, choose one of CSRS, AUSPOS and RTX, and OPUS results are not recommended.

With the wide application of satellite positioning technology, real - time satellite positioning and safe distance threshold between operator and drilling are used in dynamite seismic exploration, which effectively form an electronic fence of safe excitation distance. The setting of electronic fence (explosive area and non - explosive area) in the command center of unqualified excitation mode can effectively avoid the bad shot caused by incomplete collection arrangement or appointment quality control. Electronic detonator used in dynamite excitation has an electronic fence (explosive zone and no - explosive zone) in detonation password, which further controls the risk during the use of the detonator. This paper reviews the application principle and method of electronic fence in dynamite excitation, and brieflyintroduces the setting method of electronic fenceof electronic detonator.

In this paper, the statistical and analytical methods of vibrator time efficiency are discussed in detail, aiming to reveal the main factors affecting the duration of a single vibrator. Based on the time data recorded by the VibPro HD, this study is closely integrated with the Ultimate Source Management System (USM) (hereinafter referred to as the USM system), and the practical application and theoretical exploration of the efficiency statistical function are carried out. Through the analysis on the calculation efficiency of random experiments, the effects of moving time and waiting time for excitation on the duration of a single shot are revealed. At the same time, with the help of application cases, the simulation application of efficiency statistics function in 3D seismic exploration projects was demonstrated, and the construction scheme to maximize the efficiency of vibrators was successfully found, which provided a strong guarantee for the cost reduction and efficiency increase of the project.
