Embodiment
The embodiment of the invention as shown in Figure 1, 2, this three-dimensional well drilling rail anticollision verification method step is as follows: the pre-service of a constraint condition is about to the input and the storage of the orbital data of the track of old well and new well; The generation of b Triangular Grid Model; At first to qualified point set carrying out Delaunay triangulation, generate an initial triangulation DTS, know easily, the qualified point set has consistance with this initial subdivision DTS, differ and have consistance with DTS surely and limit line segment aggregate, in order to make the qualification line segment aggregate have consistance with DTS, constantly check the line segment that limits in the line segment aggregate, for each non-existent line segment in triangulation DTS, it is segmented from mid point, simultaneously mid point is added among the triangulation DTS, constantly carry out with this, all line segments all exist in triangulation in limiting line segment aggregate, and algorithm finishes; The advantage of the triangulation network is the well-formed, data structure is simple, data redudancy is little, the storage efficiency height, perfect harmony with irregular terrain surface specifications, can represent the zone boundary of linear feature and superposition arbitrary shape, be easy to upgrade, can adapt to the data of various distribution densities etc., be particularly suitable for the network analysis among the GIS, be a kind of best approach of describing surface configuration; C has the generation of constraint condition ground model, and just the data in a step combine with Triangular Grid Model in the b step, forms the model trajectory of the old and new's well that straight line and curve form; D rejects the well location outside the range of influence, at first definite scope that new well is exerted an influence, again the well location outside the range of influence around the new well is rejected, as default coverage radius is 200m, the track that only keeps the old and new's well in the radius 200m scope, scope outside track data and model are rejected, reduce data processing amount, concrete grammar is: earlier in two-dimension GIS with the method for " judging point whether in polygon " with well location ground side coordinate not the well array outside the diameter double-wide that new well is exerted an influence remove, use " three dimensions bounding box " method to get rid of with the disjoint well of the diameter range that new well is exerted an influence then, finally staying needs the further well location data of calculating; E determines that earlier default escape pit is apart from carrying out orbiting collision scanning then, adopt the horizontal scanning method, normal plane scanning method and minimum distance method, what the horizontal scanning method was calculated is inter-well distance on the same vertical depth cross section, the normal plane scanning method is calculated be on the new well track arbitrarily on a bit perpendicular to the inter-well distance on the vertical plane of axis, straight well section at new well track adopts the horizontal scanning method, employing normal plane scanning method between the lower curved section of new well track and equidirectional well, and adopt the surface level scanning method between the different direction well, using minimum distance method when above-mentioned scanning result instead during less than 1.5 times of escape pit distance calculates, draw minor increment between well, when minor increment between the well that scans the escape pit distance more than 1.5 times the time gain again with flat plane scanning method or normal plane scanning method and scan, scanning result shows in the f step less than the orbital distance of escape pit distance, can express by tabular form, also can show by three-dimensional or graphics, to express intuitively with the well spacing of different elevation correspondences apart from rail portion less than escape pit, be used for new well orbiting collision checking quicklook, avoid the potential safety hazard of later stage drilling well collision.
As shown in Figure 3, the upper bound, emphasis zoning is for recording new well track and old well track space from locating apart from 1.5 times for escape pit among the figure with horizontal scanning method or normal plane scanning method, the emphasis zoning is next for descending most Furthest Neighbor to record new well track and old well track space from being that the escape pit distance is located for 1.5 times, the upper bound, emphasis zoning and the section between the next time of emphasis zoning are considered as the emphasis calculation of sector and adopt minimum distance method, be specially in the key area on two mouthfuls of well tracks according to a fixed step size, get a P respectively, Q, according to 2 range formulas in space: | PQ|=√ [(x2-x1) ^2+ (y2-y1) ^2+ (z2-z1) ^2] draws the space length of 2 of PQ, try to achieve by that analogy Min (| PQ|).
Usually new well track major part is all in the safety zone, so adopting horizontal scanning method and normal plane scanning method to carry out inter-well distance scanning at ordinary times calculates, the little speed of data processing amount is fast, because the offset well that said method calculates distance is minor increment not necessarily, so adopt minimum distance method to carry out minimum distance calculation when it records the result less than 1.5 times of escape pit distance, this combination calculation mode can improve operation efficiency greatly.
This method not only can be used for the old and new's well interorbital, also can be used for new well interorbital; The minimum distance method switch threshold value can be adjusted between 1.5 to 2 times of escape pit distance.
