保护储集层的控制及模拟技术

CONTROL AND SIMULATION TECHNIQUE OF THE PROTECTION OF FORMATION FROM DAMAGE

保护储集层应以预防和控制为主，以确立预防与控制措施为主要思路。由此进行了模拟、仿真研究，运用神经网络方法研究了储层伤害的识别与诊断。建立了保护储层的计算机软件系统，它由储层伤害的识别、评价、诊断、预防、处理5个子系统，以及各子系统的知识库、系统总控、知识获取、解释器、用户接口等模块组成。储层损害的诊断、预防、控制与处理是个系统工程，已形成配套技术，它的应用已取得十分明显的经济效益和社会效益。

On the protection of formation from damage, the most importunt measure is to prevent it before the damage occuring, and to decide the ideas of proventing and controlling formation form damage.By making the simulation and emulation researches, we studied the identification and diagnesis of formation damages with the methods of neural network, as well as developed the computer software system IEDPTFD (Identification, Evaluation, Diagnosis, Precaution, and Treatment of Formation Damage) for formation protection. It consists of five subsystems and their knowledge bases, a main control module, a knowledge acquisition medule, an explanation module (interpretor) and a man-machine interview module.Indentification, evaluation, diagnosis, precaution and treatment of formation damages is a systematical engineering. A set of mating protection technologies of formation from damage has been established. Application of these technologies has abtained gtal economical and social benefitial results
