Research On The Factors And Mechanics Of M Developments Zone Causing Damage

Since 2003,M development zone casing damage problem is more and more serious,the current annual number of wells are more than 80 wells,to the oil field development to bring some impact.At the same time,the overhaul of the casing is cost a lot of money.From the current situation of casing damage in the area,the distribution characteristics of the casing and the vertical distribution of the horizon are basically understood.The reason of the damage caused by the damage,the study of the damage mechanism is only from the statistical analysis,there is further in-depth study.The purpose of this paper is to find out the main causes of casing damage caused by M development zone,to understand and understand the mechanism of casing damage,to develop targeted damage prevention measures,so as to carry out comprehensive management of casing damage to reduce oil field maintenance costs The To slow down the damage rate,do a good job in oil field development and adjustment,so that long-term efficient oil production will have a very important significance.In this paper,the main research content of this paper is based on the analysis of geological and development factors,the use of rock mechanics view,combined with oil and water wells due to injection caused by changes in underground pressure,and ultimately lead to changes in rock stress and strain theory,to explain the oil wells The source of the damage to the casing;finally,do a lot of related experiments to demonstrate the argument.This paper first summarizes the development history of M development zone,takes the on-site data as the basic condition,makes the corresponding data by making the relevant experiment,makes the overall analysis of the casing damage characteristics,utilizes the related geological knowledge,develops knowledge and rock mechanics Related theory,combined with the actual production,the purpose is to work in the oil field to help establish the oil casing protection system.
