公益性陆域油气地质调查钻探工程技术进展与攻关建议

公益性陆域油气地质调查主要针对“新区、新层系、新类型、新领域”开展基础性、公益性、战略性工作。近年来，通过部署多项油气地质调查科技攻坚战，取得了一批重要地质发现及页岩油气突破，为国家能源安全保障做出了应有贡献。但“新区、新层系、新类型、新领域”的陆域油气地质调查工作区具有复杂构造区多、工作程度低、工程实践少、资料相对缺乏的特点，导致钻探工程面临复杂故障预见性差、安全风险高、地质目的实现难度大等挑战。结合近年来油气地质调查钻探工程实践，对公益性陆域油气地质调查钻探工程总体现状、难点挑战、技术进展进行了阐述，从安全环保、取全取准各项地质资料、提速降本等角度，提出了技术攻关建议，以期对公益性陆域油气地质调查钻探工程的发展和进步起到一定推动作用。

Advances and research suggestions for onshore oil & gas survey drilling engineering for the public benefit

The public benefit onshore oil and gas survey is to carry on basic， public and strategic exploration focused on new areas， new strata， new types and new fields. In recent years， many important geological discoveries and shale oil & gas survey breakthroughs have been made through a number of scientific and technological projects in oil and gas geological survey， making contributions to national energy security. However， the geological survey work on “new areas， new strata， new types and new fields” has the characteristics of many complex structural areas， low degree of work， few engineering practices and relative lack of data， which lead to the challenges of poor prediction of complex problems， high safety risk and difficult realization of geological objectives. With respect to the practice of oil and gas survey and drilling practice in recent years， this paper expounds the overall status， difficulties and challenges， and advances in the public benefit onshore oil and gas survey drilling engineering. From the perspectives of safety and environmental protection， obtaining full and exact geological data， increasing speed and reducing cost， some research suggestions are put forward to solve technical problems so as to promote the development and progress of the public benefit onshore oil and gas survey drilling engineering.
