Introduction
Analysis of the core content of the standard
As an important part of the SY series of exploration technical specifications, this standard has established a complete oil and gas exploration well design technology system. It is complementary to SY 5518-92. The former focuses on measurement specifications, while this rule focuses on design methodology.
Comparison of key technical requirements
| Exploration well type | Scale requirement | Core design goal | Typical well depth control |
|---|---|---|---|
| Regional exploration well | ≥1:200000 | Reveal formation integrity | Meet geological mission depth |
| Pre-exploration well | ≥1:100000 | Location of oil and gas enrichment area | Reveal all oil and gas layers |
| Evaluation well | ≥1:50000 | Reserve parameter acquisition | Control of oil and gas reservoir range |
Key points for implementing geological demonstration
Taking a block in Daqing Oilfield as an example, when reprocessing the 3D seismic data, it was found that the original designed well location deviated by 320 meters from the structural high point. After re-demonstration, the well location was adjusted and the thickness of the oil layer encountered was finally increased by 4.7 meters, which verified the necessity of carrying out targeted supplementary work in Clause 4.1.3.
Analysis of Standard Evolution
Compared with earlier versions, the 1996 version of the standard mainly strengthened:
1. Dynamic adjustment mechanism (Clause 3.4)
2. Application of human-machine collaboration technology (Clause 4.1.3)
3. Requirements for risk quantification analysis (Clause 5.1.f)
Implementation Suggestions
- Give priority to the use of GIS system to integrate geographic and geological data
- Establish a multi-scheme comparison mechanism for well location design
- Strictly implement the three-level approval system of Clause 6.3
