Description
Technical field
The present invention relates to natural gas extraction technical fields, more specifically collect one kind of earthquake, geology and gas reservoir engineering
Karst-type reservoir well-arranging procedure between carbonate horizon.
Background technique
Carbonate rock hydrocarbon reservoir enters the development phase by the exploration phase in tower, and well spacing is at present with cave type karst reservoir
It is main, the success rate of type karst reservoir in cave in well is drilled within 2010 and 2011 compared with > 80%, and bore and take off crack-hole type, hole
Karst reservoir does not obtain commercial hydrocarbon flow between type, and 17 mouthfuls of wells of deployment produce no breakthroughs through probing, causes in tower well spacing difficulty suddenly
Increase.
Cave type karst reservoir well spacing screens that cave is larger, crack is compared with the reservoir of development, and early period, effect was fine, still
Preferable cave type reservoir is few, educates if remaining crack is owed, when cave scale is smaller, individual well is difficult efficiently.
For interlayer Karst-type carbonate gas reservoirs other than the limitation of the particularity of geological conditions, there is also technically or different
Professional difficult point or limitation.Such as: well location is disposed using seismic method, due to being influenced and the limit of resolution ratio by landforms
System, drilling success are lower；Crack-hole type reservoir, hole type reservoir properties are poor, easy to pollute, and need reservoir reconstruction, right
Process specifications are higher.
Publication No. CN101936165A, publication date are that the Chinese patent literature on January 5th, 2011 discloses a kind of rock
Molten type carbonate reservoir well-arranging procedure, is related to natural gas extraction technology, terminates to construct with Hai Xi in Caledonian tectonic movement and transport
The dynamic time started nearby chooses upper and lower isochronous surface, and low using isopleth map reflection ancient landform Xi Gaodong, monadnock and low-lying area are developed in part
Ground acquires seismic data, and inverting section and cross-well seismic data determine low relief structure form and evolutionary process, divides carbonate
Rock reservoir sedimentation parfacies and Microfacies Types divide advantageous sedimentary micro, using existing production well yield and survey pressure data,
It determines each wellblock reservoir connection, divide well spacing Favorable Areas and is greater than the region cloth well location of 20m in reservoir thickness.The invention well spacing closes
Reason surveys well spacing gas-bearing formation Drilling ratio 100%；Drilling success 82% obtains industrial gas in lower ancient gas-bearing formation section, saves fund.
But it using above patent document as the prior art of representative, can not be directly applied between rock carbonate horizon in tower
The well spacing of molten type oil-gas reservoir, and have the drawback that and do not account for oil-gas reservoir division symbolizing, it cannot accurately divide Oil-gas Accumulation Types
It makes troubles to later period production；Particular lithologic prediction is not carried out it cannot be guaranteed that well track navigates within inside reservoir；Do not carry out
Seismic reflection Type division, planned well can omit the corrosion Cave Development area of earthquake " beading " reflection.
Summary of the invention
The present invention is directed to for defect and deficiency present in the above-mentioned prior art, provide Karst-type between a kind of carbonate horizon
Reservoir well-arranging procedure, the present invention are directed to the complicated geologicals feature such as carbonate reservoir heterogeneity and gas-bearing formation cross directional variations, well spacing
