本文从四川天然气勘探情况出发,探讨了提高勘探效益的路子。在气田主体探明储量后,应精简扩边勘探;隐蔽性气藏发现后,一般不宜转入评价勘探;要按市场经济完善勘探部署,卡住低效井。实行稀井广探要区别对待,对不同圈闭应采用不同的布井方式,多产层构造重在落实“一井多层”,新区、新层、新领域是稀井广探的重点。提高勘探效益还要从井筒技术入手,充分利用地层自然造斜、中途VSP测井、测试、岩心标定的测井评价技术等。还要从改善勘探项目管理入手,提高勘探前期工程和项目部署设计质量,提高单项勘探工程设计的预见性,逐步完善项目经理、监督的招聘,建立一个稳定的、以地质专业为核心的多学科综合研究设计组。总之,一是走向市场,二是依靠科技,三是改善管理,这才能达到提高勘探效益的目的。
Based on the exploration of natural gas in Sichuan, this paper explores ways to improve exploration efficiency. After the main reserves of the gas field are proven, expansion exploration should be streamlined. After the concealed gas reservoir is discovered, it is generally not suitable for exploration and evaluation. Exploration and deployment should be perfected in the market economy, and the inefficient wells should be stuck. The implementation of extensive exploration of different wells to be treated differently for different traps should be deployed in different ways, multi-layer structure emphasis on the implementation of “one well multi-storey”, new area, new layer, new area is the focus of dilute wells. To improve exploration efficiency but also start from the wellbore technology, make full use of natural strata stratum, midway VSP logging, testing, core calibration logging evaluation technology. We should also start with improving the management of exploration projects, improve the quality of the design of pre-exploration projects and the deployment of projects, improve the predictability of individual exploration project designs, and gradually improve the recruitment of project managers and supervisors so as to establish a stable and multidisciplinary discipline with geological major as its core Integrated Research Design Group. In short, the first is to go to the market, the second is to rely on science and technology, the third is to improve management, which can achieve the purpose of improving exploration efficiency.
