【摘要】：研究区南二、三区西部位于萨尔图背斜构造高点，断层极其发育，交切关系复杂，，尽管萨南油田实现了三维开发地震全覆盖，但是仅靠地震资料也不能精细描述小断层的发育特征，小断层分布仍具有不确定性，影响了对本区注水开发、聚合物驱、剩余油的分布规律的研究。本文在充分利用已有的测井及地震解释等相关地质资料的基础上，对南二、三区西部断层的几何学、运动学特征进行研究，确定断层组合形态及成因分析，针对井震解释后仍然认识不清的断层区域，开展示踪剂验证断层存在及密闭性工作。结合断层形成期次划分成果和数值模拟技术进行构造期次划分，开展南二、三区西部断层成因研究，将有助于正确认识断裂构造的分布特征，对于指导萨南油田增储挖潜具有重要的实际意义。南二、三区西部油层受断层及构造影响，断块区实际开发过程中存在注采不完善井比例高，断块区注入压力升幅快，注入困难井比例高，注采能力差等问题，聚驱开发效果受到较大影响。在全面厘清研究区断层分布及构造成因的基础上，通过综合分析断块附近各套井网注采关系及油层发育连通状况，对不同井网注入采出井设计注采调整原则，使聚驱井网最大程度得到完善，聚驱效果有效发挥，从而改善了聚驱开发效果。
[Abstract]:The two and three areas in the south of the study area are located in the high point of the Saertu anticline structure. The faults are extremely developed and the intersecting relations are complex. Although the SAM oilfield has realized the full coverage of three dimensional development earthquakes, the seismic data can not accurately describe the development characteristics of the small faults, and the distribution of small faults still has uncertainty, which affects the development of water injection in this area. On the basis of fully utilizing the existing logging and seismic interpretation and other related geological data, this paper studies the geometric and kinematic characteristics of the fault in the south two and three areas, and determines the formation and formation of faults. The tracing agent verifies the existence of fault and the closed work of the fault. Combining the division results of the fault formation period and the numerical simulation technology to divide the tectonic period, carrying out the study of the fault genesis in the west of the two and three regions will be helpful to correctly understand the distribution characteristics of the fault structure, and it is of great practical significance to guide the reservoir potential of the southern oil field.
The oil layer in the two South and three region of South China is affected by faults and structures. In the actual development process of the fault block, there are some problems of high injection production, high injection and production, high injection pressure, high injection rate, poor injection and production capacity and poor injection and production capacity. Through the comprehensive analysis of the injection production relations of each set of well networks near the fault block and the development and connectivity of the oil reservoirs, the principle of injection and production adjustment for the design of the wells with different well networks is designed to improve the maximum degree of the polymer flooding well and the effect of the polymer flooding effectively, thus improving the effect of the development of the polymer flooding.
