摘要

为了解决非常规油气效益开发面临的难题,提出了“缝控储量”改造优化设计技术新概念及配套技术方法体系。“缝控储量”改造优化设计技术即通过优化形成与“甜点区”和“非甜点区”匹配程度高的裂缝体系,实现非常规油气资源的立体动用和经济高效开发。该技术以非常规油气资源为研究对象,形成了以初次改造系数最大化为约束进而提高“缝控储量”的“3优化、3控制”的技术路线和途径,通过优化井间距控制砂体范围,优化裂缝系统控制可采储量,优化补能方式控制单井产量递减。“缝控储量”改造优化设计技术强调初次改造系数最大化和补能、改造和开采一体化,延长重复压裂周期或避免重复压裂,通过参数优化和精准的控制技术,实现纵向和平面上油藏的立体全动用和高效开发,最大化实现非常规油气资源大规模、可持续、高效益的开发。在国内致密油、页岩气等5大典型区块开展了20井次先导性试验,致密油压采效果提高,页岩气实现商业开发,展示出良好应用前景。图11参24

Abstract

To solve the problems facing the economic development of unconventional oil and gas, a new concept and corresponding technology system of reservoir stimulation based on “fracture-controlled reserves” are put forward. The “fracture-controlled reserves” stimulation technology is to realize the three-dimensional producing and economic and efficient development of unconventional hydrocarbon resources by forming a fracture system that well matches “sweet spots” and “non-sweet spots”. The technical route of the stimulation technology is “three optimizations and controls”, that is, control the scope of sand body through optimizing well spacing, control the recoverable reserves through optimizing fracture system, and control the single well production reduction through optimizing energy complement method. The “fracture-controlled reserves” stimulation emphasizes the maximization of the initial stimulation coefficient, the integration of energy replenishment, stimulation and production, and prolonging the re-fracturing cycle or avoiding re-fracturing. It aims at realizing the three-dimensional full producing and efficient development of reservoir in vertical and horizontal directions and achieving the large-scale, sustainable and high profitable development of unconventional oil and gas resources. The stimulation technology was used to perform 20 pilot projects in five typical tight-oil, shale gas blocks in China. The fracturing and producing effects of tight oil improved and the commercial development for shale gas was realized.

Key words： unconventional oil and gas; tight oil and gas; shale oil and gas; fracture-controlled reserves; stimulation coefficient; fracture parameters optimization; well pattern optimization; energy complement
