The Investigation Of Exploration Methods In Inner Mongolia Region Gill

In the Sulige area there are well-developed overlaying coal-bearing hydrocarbon-source rocks, banded sand body distributed near longitudinally in the block, thick and far-ranging caprock, and the side shielding by the claystone (floodplains and distributary bays) and dense sandstone existed in this region. Therefore, a perfect play (source-resevoir-seal) of the Sulige area could be easily formed under good conditions of accumulation and preservation for the lithologic traps, with the structural features of being gradually west-inclined. Although there is huge amount of resource in this Block, the exploration rate is extremely low with even less-level exploration beyond the explored reserve block. However there still exists great exploration potential due to its favorable geological condition for gas accumulation, and so all directions of the Sulige area will be potentially advantageous exploration targets.1990s-2008, in this area, for the natural gas in upper and Lower Paleozoic, undertaken2-dimensional exploration work. The data acquisition in2000-2002, At that time limits by acquisition technology and acquisition equipment Most of seismic profile has a low resolution, Can’t meet the need of lithologic explain.2005-2007, in this area, ongoing of project for regional exploration and natural gas exploration, All acquire higher quality of seismic data. Especially in2007-2008, ongoing of work for2-dimensional acquisition work, After system Research test for excitationcondition, trace spacing and cover frequency, the data quality of Acquisition has a large improvement, The main target is Reflection can continuous tracing, reflection Between the layers inside is clear, In the relatively thin area of low velocity layer thickness can meet the needs of the lithologic explain, Improve the precision of the natural gas exploration and development.In This papers the research object is Jill area of Etuoke Banner churchyard, in the foundation of the analysis of In and around the area of the geological, earthquake, drilling, past old data, Combined with the years of exploration data achievements, Based on investigation and analysis number of related literature, research of the new method Suitable for this area in seismic exploration, optimum and design the gathering parameters Suitable for earthquake foundation, To improve research area gas seismic exploration effect.This research is to be expected to improve Jill region-field seismic data acquisition provides a strong technical support. For Changqing Oil Field Company to achieve the grand goal of annual capacity of35billion cubic meters of natural gas in2015, laid the important foundation.
