西部ZZ厚沙漠区地震采集关键技术研究
|
摘要
沙漠是西部探区的主要勘探区域之一。西部准噶尔中部区块大部分位于古尔班通古特沙漠中,是典型的沙漠区,存在低降速层巨厚、目的层埋深大、激发接收条件差、静校正困难等技术难点,难以获得高品质地震资料,严重制约了勘探开发的进展。文章针对沙漠的采集难点开展了深入研究,提出了超深微测井、沙丘曲线调查、低速层潮湿沙层多浅井小药量组合激发、井检联合压噪等关键技术,并进行了钻井工艺革新,有效地提高了该区的地震资料品质。
The desert is one of the main exploration area in west exploration area.Most of the area in the middle of Junggar in the west of china is located in Gurbantonggut desert,and it is typical of the desert area.It has technical difficulties of thick low velocity layers,deeply buried target layer,poor conditions of inspire and reception and static correction difficulties,etc.It is very difficult to get high- quality seismic data,and seriously hampers the progress of exploration and development.In this paper,we conducted deep researches on acquisition difficulty of desert,proposed key technologies,such as ultra- deep uphole,dune curve,multi- shallow well array stimulate with small dose in Low- speed- wet sand,and so on.We also carried out the drilling process innovation,which effectively improved the quality of seismic data in the area.
