Abstract
The interval arrangement method for 3-D seismic survey of oil field features that 21 acquisition stations, each having 4 receiving channels, are arranged on each of 8 parallel acquisition lines which are divided into 7 intervals of 600 m X 700 m. Its advantages include low construction cost and simple construction process.
Description
The invention belongs to the oil field geologic Exploration Domain, particularly a kind of interval construction method of arranging of oil field three-dimensional seismic prospecting that is used for.
Carrying out 3-d seismic exploration with earthquake at home and abroad at present need be at several survey line of ground configuration when the collecting work, and on every survey line, be provided with many earthquake-capturing stations (being wave detector), be used for receiving the wave beam that comes through the stratum reflection from seismic origin emission, again these ripples are delivered to via lead and carried out record in the seismograph, at last, through computing machine these waveforms of receiving are put in order, be depicted as structural map through the long-pending underground structure that just can search out the possibility oil storage that is situated between, therefore the arrangement and the arrangement speed of survey line is a vital ring in the open-air seismic work when seismic prospecting; Existing technology is when survey line carries out series arrangement, usually adopt a line three car line falling methods (promptly after finishing each seismic event reception task, a survey line is moved to an other place, and carry out line falling) with three automobiles, this method can be divided into that four lines are arranged and the arrangement of eight lines, during construction will with the wave detector (reception channel) above every row's survey line from left to right side put in order.As when meeting the arrangement of eight surveys line (collection line), the per pass line will have 60 reception channels, distance is 50 meters between each reception channel, promptly a survey line total length can reach 3 kilometers, the staff will put each reception channel above the acquisition station on 3 kilometers long roads from the beginning to the end with a special line falling car during line falling, article eight, survey line needs eight line falling cars to set out simultaneously, therefore, operating efficiency is low especially, take a lot of work and require great effort, when only 3-D seismics team in Liaohe Oil Field constructs, furnish the funds of just spending more in the construction time that are arranged in that have 672 reception channels and reach nearly 1,000,000 yuan.
Purpose of the present invention is just in order to overcome shortcoming and the drawback that above-mentioned 3-d seismic exploration aligning method is brought, and a kind of interval construction method of arranging that provides, it has been broken the construction method that adopts traditional single line three car line fallings wiring and has used a kind of subregion arrangement mode, arrange interval ranges as long as each bar survey line (acquisition station) that ground is distributed is divided into seven during construction, personnel focus on certain and intervally just can replace three vehicles in reaching three kilometer range every survey line to be carried out miscellaneous work with a vehicle during work.
The present invention is achieved in that
Illustrated below in conjunction with accompanying drawing:
Accompanying drawing: the interval construction synoptic diagram of arranging of a kind of 3-d seismic exploration
The present invention is made up of survey line 1 (collection line), acquisition station 2, interval 3.
The present invention is a kind of improvement on former 3-d seismic exploration construction basis as carries out three During the dimension seismic prospecting, in survey area, eight surveys line (collection line) 1 are distinguished parallel Row come, and its interval of survey line is 100 meters, are furnished with 21 acquisition stations 2 above the every survey line, At each acquisition station 24 reception channels (be wave detector, do not mark among the figure), per pass are set again Be divided into above the survey line and be furnished with 84 reception channels, the acquisition station spacing is 200 meters, then, and again Eight surveys line 1 are divided into seven intervals 3 according to 600 meters * 700 meters specifications, at last at each When the interval separated (not drawing among the figure) line falling with flag between the road of different colours, construction team only needed Each minizone work can realize task proposed by the invention.
The present invention compares the advantage that has with traditional construction method: when carrying out the oil field During 3-d seismic exploration, because survey line adopts the interval construction method of arranging to overcome in the past line falling Car is got to the drawback of arranging tail end from the survey line beginning, at every turn when line falling, and vehicle Only need on survey line, to walk original 1/8 distance, just can finish the line falling task, make in addition Go construction can also save a large amount of vehicles with method of the present invention, every survey line needed in the past 3 line falling cars are engaged in work, arrange survey line for one and just need 20 chassis, by annual 100 days The earthquake construction time calculates a construction time and just spends more 600,000 yuan of expenses, exists as adopting the inventive method Checking just can be without vehicle when acquisition station is arranged. The only collection on move the survey line arrangement It is just passable to employ a chassis during article, all adopts this interval the arrangement such as national earthquake team Method can be saved the nearly millions of units of vehicle in 1 year.
The present invention gives prominence to is also advantageous in that and uses the present invention that equipment can be concentrated in the interval that an eyesight can reach, distance is short, it is fast that the line falling task can be finished, the measuring task that will finish an arrangement needs 8-9 hour at least and classic method is because circuit length is slow in action, the present invention's construction method more in the past compares and can improve timeliness more than 4 times and significantly reduced labour intensity, simultaneously, returning the walkaround inspection survey line layouts and has brought convenience.
Because the present invention constructs simply, have certain economic benefit and fundamentally changed traditional construction technology, therefore, can be extensively in oil, coalfield, geologic prospecting work.
