Print this pageMahu sag petroleum system in northwest
edge of Junger basin in China has multiple source rocks and multiple periodical
pool formation basing on the active and growing Kalamayi fracture as a
migration
route. The application of present-day welling technique makes
it possible that capturing the oil and gas in these high porosity and permeability
areas. The research has completed three steps:
1. Collecting and setting of data (The emphases
are the effects about growth fault and the migration of oil and gas and
the factual data of Junger basin.);
2. Finding out the tectonic fault system of the
Kelamayi oil field by seismic interpretation;
3. Studying the oil-source correlation and thermal
mature history of source rocks.
The next work will be carried out according to
following two facets:
1. Physical experimental technique and Computer
software simulation will help to understand the relationship between the
histories of oil and gas generation and their migration along the growth
fault in Kelamayi oil field, and the effect of migration and accumulation
by this mechanism today;
2. Indicating the advantaged target and area
by knowledge about the migration principle of oil and gas along the active
growth fault and designating the goal of welling and production.
The project will not only greatly extend the exploration
and development theory today in capturing the accumulated oil and gas along
the growth fault
during drilling, but also accelerate the research for
non-tectonic shady oil & gas traps.
