特低渗透油藏大型压裂技术研究与应用

Research and Application of Large-scale Fracturing Technology in Ultra-low Permeability Reservoir

通过对特地渗透油藏开发技术调研和反复论证,认为"定向、定量地造长缝"的大型压裂技术是实现特低渗油藏效益开发的关键。针对富112块沙三下段特低渗透砂岩地层,应用stimplan整体压裂优化模拟软件开展了压裂工艺技术优化研究。实践证明,大型压裂技术不仅解决了富112块沙三下段油藏的开发难题,而且对实现特低渗透油藏效益开发具有重要的参考价值。

Through investigation and argumentation on the development technology of ultra-low permeability reservoir,the Large-scale fracturing technology which can form long fissure directionaly and guantitatively is considered as the key technology of the economic benefit development technology of ultra-low permeability reservoir.With the example of the parameters of Fu112 Block ultra-low permeability oil reservoir,the Large-scale fracturing technology was studied and optimized using the Numerical Simulation Software（STIMPLAN） of Systematic Fracturing for Reservoir.Field application shows that the Large-scale fracturing technology both applies to Fu112 Block reservoir and may have reference value to the ultra-low permeability reservoir for economic benefit development.
