Problems solved by technology

However, the latitude and longitude coordinates are often inconsistent with the plane coordinates in the area to be explored, which will cause the collected latitude and longitude coordinates to be unable to accurately represent the actual location of the wellhead, and will also result in waste guns

Abstract

The invention provides a wellhead positioning device and method. The device comprises an acquisition end, a receiving end, a blasting machine and a seismic apparatus host, wherein the acquisition end is arranged in a preset position of a wellhead and used for acquiring first geographic information of the wellhead and sending the first geographic information to the receiving end; the receiving end is connected with the blasting machine through a preset port and used for pushing the first geographic information to the blasting machine; the blasting machine is used for sending a request command including the first geographic information to the seismic apparatus host; the seismic apparatus host is used for converting the first geographic information into second geographic information as per a preset rule according to the request command sent by the blasting machine and acquiring a flag number of the wellhead corresponding to the second geographic information. With the adoption of the wellhead positioning device and method, the actual position of the wellhead can be determined automatically and accurately.

Description

technical field [0001] The present application relates to a remote explosion system for seismic data acquisition, and in particular to a wellhead positioning device and method. Background technique [0002] In the process of exploration and development of oil, natural gas and coal resources, several wellheads can often be arranged in the area to be explored, and each wellhead can be used as a shot point. By detonating explosives on the shot point, seismic waves can be generated. By collecting the seismic waves refracted and reflected in the formation and analyzing the collected seismic waves, the geological structure of the area to be explored can be known. [0003] The above-mentioned process of obtaining the geological structure of the area to be explored may be referred to as a well shot construction process. In the process of well shot construction, positioning the wellhead is often an important step, because once the wellhead positioning is not accurate, it will often ...
