摘要

在深埋藏碳酸盐岩裂缝型储层中，裂缝既是主要的储集空间，又是重要的渗流通道，其发育程度直接关系到油气藏聚集规模和单井产能大小，但该类油藏埋藏深、经多期构造作用和岩溶作用改造的特点使储层内裂缝分布规律极为复杂，裂缝识别和预测难度大，裂缝空间分布和属性参数表征困难。本文根据示点性过程模拟理论，提出基于示点性过程模拟的碳酸盐岩裂缝型储层建模方法，并以塔河油田X区裂缝型油藏为例，利用蚂蚁体属性数据约束单井裂缝密度插值得到裂缝密度分布模型，进而在裂缝产状统计数据和裂缝密度分布模型的约束下，建立了研究区离散裂缝网络模型，直观刻画了油藏内裂缝网络的空间形态和结构，为准确描述裂缝系统的连通性、非均质性及渗流行为提供有效的地质模型，丰富了储层建模方法研究，对有效开发碳酸盐岩裂缝型储层具有一定的实际意义。

Abstract

The cracks not only serve as the major reservoir space, but also as the important fluid flow channel in deep buried carbonate fractured reservoirs, and the development of fractures controls the scale of reservoirs and the productivity of a single well directly. Such reservoir features deep buried depth and complicated distribution of fractures due to the reformation of reservoirs. The crack identification, fracture prediction, and fracture characterization are very difficult. In this paper, a modeling method of carbonate fractured reservoir based on the marked point process simulation theory is proposed. The fracture density distribution model is established through the single-well data interpolation under volume constraints with attribute of ants. Taking the fractured reservoirs in Tahe X area as an example, a discrete fracture network is built with fracture occurrence statistical data and fracture density distribution model constraints. The discrete fracture network modeling can be intuitively reflect the fracture's space form and structure, to provide an effective geological model for the research of connectivity, heterogeneity, and percolation characteristics of the fractured system. This method can be used in reservoir modeling and development of carbonate fractured reservoirs.
