Method for grouping and priority processing in intelligent well gun source driving

Abstract

The invention discloses a method for grouping and priority processing in intelligent well blasting source driving, which comprises the following steps: firstly, dividing N blasting machines into a group A, a group B and a group C according to geographic positions, classifying the similar blasting machines into one group, then staggering and alternately sequencing the blasting machines in the group A, the group B and the group C in time by adopting a time-sharing collaborative excitation control method, and calling a roll through a central control radio station, blasting the blasting machines in sequence in sequence; and an urgent point name unit is arranged in the roll call of the central control radio station. According to the method, grouping and time-sharing cooperative excitation control are combined, a large amount of coordination time can be saved, it is only needed to compile groups and group members in advance, meanwhile, the preferential blasting unit is further arranged, urgent blasting is processed preferentially, and time is saved.

Description

technical field [0001] The invention belongs to the technical field of well shot source driving, in particular to a grouping and priority processing method in intelligent well shot source driving. Background technique [0002] As the country's demand for oil and gas increases, the rapid increase in reserves and production in oil and gas fields requires geophysical exploration to improve quality and efficiency. With the advancement of seismic acquisition technology, the data acquisition efficiency has been continuously improved. The acquisition efficiency of offshore and onshore vibroseis has reached 1500-2000 shots per hour, but the maximum efficiency of mountain well shot acquisition can only reach about 200 shots per hour. The reason: mainly because the mountain terrain is complex and the communication conditions are extremely poor, the construction can only be carried out by manual relay, the collection efficiency is difficult to improve, and it is easy to cause errors in...

Problems solved by technology

[0007] However, in practical applications, the following situations also occurred, which affected the overall work efficiency

[0008] 1. How to arrange the blasting sequence of N blasting machines? When one of the blasting machines blasts, will the nearby blasting machines be affected accordingly? When the entire blasting project line is very far away, manual coordination is required for alternate blasting. For example, the No. 1 blasting machine in the east blasts first, followed by the No. 2 blasting machine in the west, and then it is the turn of the No. 3 blasting machine in the south, and then it is the turn of the No. 4 blasting machine in the east, and so on. The blasting needs to be confirmed manually, which is a waste of time

[0009] 2. If there is a problem with a certain shot point, the central control radio station sent a blasting command but did not blast, and the shot point needs to wait until all the blasting is completed before it can be blasted. There is no expedited blasting unit, and this point cannot be blasted first. The members of the blasting point need to wait for the blasting to be completed before proceeding to the next place, which not only delays the blasting at the wellhead, but also delays the overall process.
