The synthetic geology research obtains the following steps are included: to reservoirs all within the scope of oil reservoir progress rhythm detail stratigraphic division
Take deposition characteristics data, reservoir characteristic data, characteristics of reservoirs data；According to rhythm detail stratigraphic division result, deposition characteristics data, storage
Layer characteristic, characteristics of reservoirs data, determine reservoir distribution and oil in place, are carried out by reservoir distribution and oil in place data
Geologic modeling；
The reservoir engineering research is the following steps are included: carry out development behavior analysis, well pattern reformation analysis, Well Pattern And Spacing survey
Examination, recovery ratio analysis；
(c) combine synthetic geology research, reservoir engineering research, pilot test as a result, progress numerical simulation, according to described
Numerical simulation result determines remaining oil distribution, arranges adjustment well pattern in remaining oil distribution close quarters.
This method takes full advantage of old filed development behavior data abundance, geologic structure thoroughly research, detail stratigraphic division understand
Clear characteristic has sufficiently carried out synthetic geology research, reservoir engineering research, pilot test.Wherein synthetic geology research
It is that can accurately be determined according to rhythm detail stratigraphic division result, deposition characteristics data, reservoir characteristic data, characteristics of reservoirs data
Remaining reservoir distribution and remaining geologic reserves.Analyzed in conjunction with the development behavior in reservoir engineering research mid-early stage development process,
Well pattern reformation analysis, Well Pattern And Spacing test, recovery ratio analysis, and pilot test is combined as a result, obtaining the whole complete number of oil reservoir
It is worth analog result, so that the remaining oil distribution situation that do not developed is immediately arrived at according to numerical simulation result, to open to be secondary
Hair provides sufficient theoretical foundation, convenient for the arrangement adjustment well pattern directly in remaining oil distribution close quarters, avoids adjustment well weight
Arrange or arrange very few problem again, solve lack in the prior art it is whole to high dip angle old filed, rationally, can implement in full
Development strategy the problem of, realize to high dip angle old filed it is secondary start provide integral layout thinking purpose.
It further, further include that the well data that are drilled in the first development process of ultralow pressure oil reservoir are extracted, with first
Well data are drilled in secondary development process to optimize referring to the secondary well that is drilled of progress.This programme is that the well construction that is drilled of adjustment well mentions
Sufficient data supporting has been supplied, engineering risk is reduced, has improved engineering construction efficiency.
Preferably, the pilot test is to decline to carry out exploration well oil test operation near most slow oil well in yield.
Compared with prior art, the present invention having the following advantages and benefits:
High dip angle oil reservoir of the present invention optimizes and revises method, takes full advantage of old filed development behavior data abundance, geology knot
The cheer and bright characteristic of structure thoroughly research, detail stratigraphic division has sufficiently carried out synthetic geology research, reservoir engineering research, elder generation
Lead test.Wherein synthetic geology research is according to rhythm detail stratigraphic division result, deposition characteristics data, reservoir characteristic data, oil reservoir
Characteristic can accurately determine remaining reservoir distribution and remaining geologic reserves.It is opened in conjunction with reservoir engineering research mid-early stage
Development behavior analysis, well pattern reformation analysis, Well Pattern And Spacing test, recovery ratio analysis during hair, and combine pilot test knot
Fruit obtains oil reservoir integrally complete numerical simulation result, to immediately arrive at the residue that do not developed according to numerical simulation result
Oil distribution situation, so that sufficient theoretical foundation is provided for secondary development, convenient for the cloth directly in remaining oil distribution close quarters
Set adjustment well pattern, avoid adjustment well repeat arrange or arrange very few problem, solve lack in the prior art it is old to high dip angle
Oil field is whole, rationally, the development strategy that can implement in full the problem of, realize to high dip angle old filed it is secondary start to provide it is whole
The purpose of body layout thinking.
