油气藏勘探阶段划分与思考

为了掌握正确的油气藏勘探理论、技术和程序,快速找到油气藏,实现科学效益勘探,从盆地石油地质勘察入手,对油气藏勘探的全过程进行了研究。详细解析了油气藏勘探的行业和企业标准,重新定义了圈闭评价和油气藏评价,提出了勘探评价井和油藏评价井概念。在此基础上,建立了新的油气藏勘探的盆地勘探、圈闭预探、圈闭评价3阶段划分方案,并指出了各勘探阶段的技术方法和基本任务。新划分方案油气藏勘探程序清晰准确,更便于指导油气勘探生产实践。

CLASSIFICATIONS AND THOUGHTS ON THE OIL & GAS RESERVOIR EXPLORATION STAGES

In order to correctly master the theories,techniques and procedures of the oil & gas exploration to rapidly find out the petroleum reservoirs and realize scientific and economical exploration,from the viewpoint of the petroleum geological survey of the basin,the whole process of the oil & gas reservoir exploration was researched.The petroleum trade and company standards were analyzed in detail and the trap appraisal and petroleum reservoir evaluation were redefined,and moreover the concepts of the exploratory appraisal well and reservoir evaluating well are presented.On the basis of the above,the new three-stage classifying scheme i.e.basin exploration,trap preliminary exploration and trap appraisal was proposed for the oil & gas exploration,and moreover the technical methods and basic task were determined for each stage of the exploration.The exploratory procedure of the oil & gas reservoir of the new classifying scheme is more clearer and accurate,so it is feasible to guide the operation and practice of the petroleum exploration.
